Cool content !! Here in Brazil E100 is totally usual .. we are even used to calculate if it worths more going over Gasoline or Ethanol once filling up the tank ... Almost all cars have the ability to accept both fuels .. we call them flex fuel .. but some new models are going to be only Ethanol again to increase its fuel economy ..
Outstanding modules! Well explained and relatively simple to follow. Not sure if anyone else is interested, but I would like to see a course on tuning MFI NA and blown motors utilizing E85/E98. Thank you!
Glad you enjoyed the video and cheers for the comment =) MFI isn't on our radar at the moment to be honest. It's not something Andre has experience in himself to be able to easily produce a course on, plus it is not very requested. That said, as we grow and new staff come on board we are open to covering topics that are within their skill set such as MFI tuning, carbs etc - Taz.
@@hpa101 No dramas mate ;) I appreciate the reply. I was hoping some guys who run tuff skid cars at Gazzernats and the like would be interested on learning and sharing blown MFI tuning tips. I'm building a 461ci BBO with a Hampton Super II on Kinsler/Enderle injected E85.
You also seat at 45% throttle vs 60% throttle for the same engine speed in Ethanol test , + engine run ~20°C cooler at the start of the test . I assume that can change the output too , not only the fuel .
Izaak Ramsay what kind of country is it? I'm from Europe and have to listen often twice a time because for me it is very hard to understand. On the other hand, I'm not a native speaker. 😅
Well done sir! At this point all I have to do is watch your videos and I wont have to go to a tuning school and spend many many thousands on a formal education
There is actually no formal qualification for tuning that is officially recognized, so you can spend thousands and still not have the skills an employer wants. Just manage your time well (don't forget that is worth something too), even with free content, start to use it to gain practical experience and you'll be on the right track =) - Taz.
We comprehensively cover road tuning in our course material and also members-only webinar archive. There are a few road tuning related questions in the [HPA Q&A] videos too if you have a bit of a search ;) - Taz.
We do cover both Road and Dyno tuning techniques in our Practical Tuning courses as we're firm believers in using both. Even though a lot of people start out with Road/Street Tuning they often end up with Dyno access in the future so it's also nice to have all of the information there from the start - Taz.
Agreed, This was some great data and method illustrating many of the important factors. I self tune my own turbo car on street with a knock limited Subaru and have started working on an E85 tune. It was nice to see see data to back up my results that E85 likes a little bit less timing at lower loads which I presume is allowing for a bit more heat in the combustion to reach max VE. Thanks again.
in your experiance are knock sesnors a reliable tuning tool for a drag racing right around 1000hp e85 and 10-12psi of boost? looking to switch to efi trying to select a ecu, wondering if knock sensors are going to be something I want to use or if they will give weird issues
So in theory, if you don't encounter knock say 3 degrees after MBT, negating strength of engine components, the basic dimensions of the engine can put up with a higher compression ratio/more boost at that sector of the map?
Need a programmer for a 2002 ford thunderbird. Tried SVT and other brands as well, tripped the pas anti theft system before even downloading the stock tune. Can't find any compatible tuners on the web. What's the big secret? Anyone know why a simple tuner won't work on this model car when they work on almost any other model ford?
So why does the engine want less timing on ethanol? I had assumed it would want slightly more timing because the octane rating of E-85 is higher than pump gas, and it takes longer to burn. What octane was the regular gasoline you used?
Common misconception, you are not alone with this. You have made a huge mistake in your assumption though as ethanol burns FASTER, not slower.. th-cam.com/video/qy_rKQCSevc/w-d-xo.html That explains it and I promise it is quick and to the point, but for TL:DR, ethanol burns faster and cools the combustion charge more. Hope that helps! Octane is irrelevant when you are looking at ethanol blends vs outright gasoline and your specific question - Taz
Glad you enjoyed it! Email me before you hand over any hard earned cash and I can make sure you are getting the best deal we have going at the time =) - Taz. support@hpacademy.com
What was the octane number of the fuels tested? Or it's comparing apples to oranges? I would expect the same ignition timing at full throttle for the same octane number. Apparently the E85 octane was 2 points higher which resulted in 3 degrees difference
i want at least a good start to hondata but problem is that fee is expensive for me here in the Philippines at least put a bginner's guide on efi tuning to hondata here

I have a 2013 kenne belle supercharger with a stock ECU that was reflashed by a tuner. It’s a 6.4 liter with stock internals. 2.8 kenne bell liquid cooled. Approx 6lbs of boost. On e85. It made 566rwhp. Will this class teach me how to effectively tune this motor for max performance with the stock internals? I have access to a chassis dyno. All I need is the tuning knowledge. Also are you familiar with the diablo platform for mopar engines?
Best explanation on how to tune timing. Just one question as I don't understand English perfectly. Do you use speed limiter or just try to maintain the accelerator as smooth as possible when you're tuning?
Glad you enjoyed it! So in this example the dyno we use limits the RPM to whatever we set it to. You only use that function in the low to mid rev range, and then you start doing sweeping runs through the high RPM range as it wouldn't be good for the car to sit there on the limiter while tuning haha. To simulate this on the road, you use left foot braking to hold the RPM instead. it is called 'steady state' tuning if you want to look into it a little more. Hope that helps - Taz.
@@hpa101 I understand perfectly ty so much and I have a dumb question because if it was that I guess you would have told me. Using speed limiter can't work right?
I haven't tried that but generally a speed limiter has the RPM fluctuating, and since we what to hold the RPM rather than speed, I'm not sure it would really be better than simply left foot braking to be honest: www.hpacademy.com/previous-webinars/the-key-to-road-tuning-left-foot-braking/?

Hello, I have a Subaru Impreza compression ratio 8:1 with 100% ethanol. How high would the ignition advance be at 60 kpa and 120 kpa, do you also have any data?

Hey Andre I read one of your past articles and it says motec doesn't support flex fuel but you wrote a program correction for flex fuel my question is does motec support flex fuel now
Well, at low throttle, there's roughly 3° gap b/w E85 and gasoline (30° vs 33°). At mid throttle, 6° gap b/w E85 and gasoline (25° vs. 19°) with the side effect of being knock limited on gasoline. It seems your bench is a Toyota 86 / 4U-GSE engine / direct injection. How these gaps would be on a V6 engine with indirect injection ? Can these gaps increase or decrease according to the engine configuration !?
Correct, those gaps mean nothing and will vary wildly across different engines and setups. This is why we have to tune and why we can't just work out what the engine wants based off another engine, or even an engine that is the same. It's simply not possible to do with any kind of reliability - Taz.
Hi Mohamed, that is a tough question to answer. the EFI Tuning Fundamental course teaches the fundamentals. For some this is enough information to start tuning, it also helps when you do other research online to sort the fact from fiction. For others more information is required, for those people we have more in-depth courses that teach a step by step process for tuning, which is a great guide to use. Either way the EFI Tuning Fundamentals course is the best place to START learning how to tune. The one thing to remember about tuning is your learning is never finished. Even experienced tuners are learning new things every day. Hope that helps.
You need to use a dyno to find MBT. You can get close with road tuning, but there is some 'educated guesswork' involved rather than hard data like a dyno gives you - Taz.
I am a bit confused perhaps someone can clear this up: You needed LESS ignition timing during vacuum to achieve mbt with ethanol but use more ignition timing during boost? should I be lowering ignition timing during closed loop operation for best efficiency? I already have open looped tuned well with more timing compared to gasoline. It almost seems reversed between closed and open loop operation.
During vacuum you are not knock limited with pump gas so you go with the timing that makes MBT for the fuel you are using which for E85 is less than pump gas. For the engine they tested it knocks before it gets to MBT on pump gas under boost. With E85 it is less prone to cause knock so you can continue to add timing until you get to MBT.
Yes. We just chose two points to highlight the differences in knock limited an non-knock limited operation. When we actually perform a complete tune we want to optimise each ignition cell to achieve MBT. We don't however use the Torque Optimisation test in every cell as this would be too time consuming. During normal tuning we are just using the torque feedback on the dyno to find MBT.
Running a diesel on filtered waste oil requires 10 to 30 percent gas to thin the mix. You could probably substitute in e85, but lubricity tests should be done first. More of a Project Farm type of thing
He makes it look easy eh! Years of practice ;) You can set the max RPM via the Mainline dyno and then you adjust to control the load. You can also 'wedge' your foot in certain places to give extra control/different leverage points depending on the vehicle you're in, but like anything, 'practice makes perfect' - Taz.
Great question, here is a reply Andre gave for a similar one, hope it helps: www.hpacademy.com/forum/general-tuning-discussion/show/lambda-on-e85 - Taz.
What specific courses are you looking at? We firmly believe they are the cheapest part of learning how to tune, but you can always email with your learning goals or specific courses you are interested in and see if we have an active coupon going to help you out. If you're new to tuning I promise you that you won't regret it. It's easier to put value on buying a big new shiny turbo vs knowledge, but the knowledge will last you a lot longer and be more useful ;) Most people spend way more on phones and beer alone in a year than they do on their own learning 😅 - Taz. support@hpacademy.com
@@hpa101 hi, thanks for the honest reply, I bet they are valuable for tuning but I'm not certain if I'm gonna get in tuning at all. I don't say that they are overpriced, I respect your work, but it's way too much for me for now. the starter tuning package is $417, which is almost half my monthly wage. I'm an engineer in some country. I guess I'll just start from the free lessons and see where it goes!

For full throttle tuning with a carburetor get your fuel mixture optimized than use acceleration tests to find the timing that gives you the quickest acceleration. Advance your timing 1 degree at a time until you detect knock or your times get slower. For the timing curve it will depend on your engine combo. You can change that with different weights, springs, and stops in your distributor. Then you will want to tune your vacuum advance.
Hopefully this is a good, helpful start for you 😎 We also have another good free lesson here using gasoline, but you need to learn how to tune with that before you tune using E85 or similar: www.hpacademy.com/free-live-lesson? - Taz.
Hey Joseph, you need to learn the same things if you plan to remote tune, but realistically you want hands on experience before doing anything remotely. Even using your own low powered NA project for this experience is worth it. TL:DR: Yes, but it isn't as simple as you might think - Taz 👨🏻 www.hpacademy.com/free-tuning-lessons
Ah ok im from the srt4 counity and e tuning is very popular i have a decent understanding on how timing works and a little about ve tables and trying to learn about injector scaling my tuner uses cmr and hp im currently tuned on cmr i have guides on tuning bht thanks for the input!
Though the information given to this course are excellent your accent is so hard to understand for a non English speaking person. Even TH-cam have difficulties translating you English in to English🤣🤣 Please correct this and I will definitely take the full course 👍
Yes it can. In fact in some countries (I think in Portugal, but I'm not sure) it's used as a main fuel. The problem with running on pure ethanol is that you can't start a car when it's cold, so it works only in warm climates. Even in countries where it's used as a main fuel, cars usualy have small reservoir for petrol used only for starting a car in cold weather.
In Brazil is very common since 70's. Recently the cars started to use the heated injectors technology, so, there's no more need the gasoline reservatoir.
Can i simply increase timing in my load threshold during WOT say i have a minimum of 1.3 load at WOT and a max of 2.4 at WOT , can i up the timing from 3000rpm to redline between 1 3 and 2.4 of load until it knock and back it off and just leave the rest of the table the way it was and have only changed it wher it sits at wide open?

What are the pros and cons of running e85 on an engine with a compression ratio lower then 9.0:1?
Can you explain why is there 10% throttle difference between the two fuels at high loads?
So basically is a gasoline timing table the same as alcohol? Or is the curve different?
I've been tuning for close to 14yrs now, and seeing the approach taken to cover tuning topics, is superb! Well done!

Hi Mohamed, that is a tough question to answer. the EFI Tuning Fundamental course teaches the fundamentals. For some this is enough information to start tuning, it also helps when you do other research online to sort the fact from fiction. For others more information is required, for those people we have more in-depth courses that teach a step by step process for tuning, which is a great guide to use. Either way the EFI Tuning Fundamentals course is the best place to START learning how to tune.
The one thing to remember about tuning is your learning is never finished. Even experienced tuners are learning new things every day.
Hope that helps.
Is advancing the timing a lower number on the timing table?
Going from 10 deg before tdc to 12 deg btdc is advancing
Is possible obtain MTB due to dyno or by the ECU of the car?
You need to use a dyno to find MBT. You can get close with road tuning, but there is some 'educated guesswork' involved rather than hard data like a dyno gives you - Taz.
Can this principle work on a rotary engine
I am a bit confused perhaps someone can clear this up: You needed LESS ignition timing during vacuum to achieve mbt with ethanol but use more ignition timing during boost? should I be lowering ignition timing during closed loop operation for best efficiency? I already have open looped tuned well with more timing compared to gasoline. It almost seems reversed between closed and open loop operation.
During vacuum you are not knock limited with pump gas so you go with the timing that makes MBT for the fuel you are using which for E85 is less than pump gas. For the engine they tested it knocks before it gets to MBT on pump gas under boost. With E85 it is less prone to cause knock so you can continue to add timing until you get to MBT.
Would you usually try and find mbt at different points on the map as well, say 4500rpm at 60 and 120kpa?
Yes. We just chose two points to highlight the differences in knock limited an non-knock limited operation. When we actually perform a complete tune we want to optimise each ignition cell to achieve MBT. We don't however use the Torque Optimisation test in every cell as this would be too time consuming. During normal tuning we are just using the torque feedback on the dyno to find MBT.
What about diesel? Can one use ethanol in Diesel engines? Thanks for the information!
No. Diesels work completely differently, as they are essentially a compression ignition engines ie. no spark.
Running a diesel on filtered waste oil requires 10 to 30 percent gas to thin the mix. You could probably substitute in e85, but lubricity tests should be done first. More of a Project Farm type of thing
How do you keep the throttle so steady?
He makes it look easy eh! Years of practice ;)
You can set the max RPM via the Mainline dyno and then you adjust to control the load. You can also 'wedge' your foot in certain places to give extra control/different leverage points depending on the vehicle you're in, but like anything, 'practice makes perfect' - Taz.
Steady state dyno
when your ecu can be live tune and have awesome software, the whole world is much nicer.
so does it matter what load this test is done under ?
Do you have to repeat the process for every cell?
Yes every cell will be tuned either manually or via interpolation depending on where it is in the map =) - Taz.
was the target lambda the same on both pump gas and e85? thanks
Great question, here is a reply Andre gave for a similar one, hope it helps: www.hpacademy.com/forum/general-tuning-discussion/show/lambda-on-e85 - Taz.
it$s good lesson for me thinks
your courses are of very high quality but they are very expensive ;(
What specific courses are you looking at? We firmly believe they are the cheapest part of learning how to tune, but you can always email with your learning goals or specific courses you are interested in and see if we have an active coupon going to help you out.
If you're new to tuning I promise you that you won't regret it. It's easier to put value on buying a big new shiny turbo vs knowledge, but the knowledge will last you a lot longer and be more useful ;)
Most people spend way more on phones and beer alone in a year than they do on their own learning 😅 - Taz.

@@hpa101 hi, thanks for the honest reply, I bet they are valuable for tuning but I'm not certain if I'm gonna get in tuning at all. I don't say that they are overpriced, I respect your work, but it's way too much for me for now. the starter tuning package is $417, which is almost half my monthly wage. I'm an engineer in some country. I guess I'll just start from the free lessons and see where it goes!
@@klazzera you have a 60-day refund policy option because we know what that is like too, the uncertainty and 'analysis paralysis'.
Forget about the package deal and it's bigger price tag for now, start with a single course, make it this one: EFI Tuning Fundamentals: www.hpacademy.com/courses/efi-tuning-fundamentals/?hpa-acc=HELPDESK50
If you want to upgrade to the package deal in the future we can credit what you paid for this against it, if not, that's cool, and if you decide there is no value in this course or tuning isn't for you within 60 days, boom, refund. We honestly don't mind you buying and refunding if you change you mind, that's why we offer the option, so don't be afraid to commit a little and find out for sure 😎- Taz.

@@hpa101 Yeah I just saw that I can buy courses one by one and it makes much more sense! I also just emailed you, thanks for your replies!
No worries at all! Lauren bet me to your one but I'm sure she got you sorted. Any issues just sing out 😎 - Taz.
Can you cover this but with a carbureted engine.
What is a "car I rated engine" I don't understand? - Ben
@@hpa101 Sorry I meant carbureted engine.
We only cover EFI sorry Sam - Taz.
@@hpa101 okay ;(
For full throttle tuning with a carburetor get your fuel mixture optimized than use acceleration tests to find the timing that gives you the quickest acceleration. Advance your timing 1 degree at a time until you detect knock or your times get slower. For the timing curve it will depend on your engine combo. You can change that with different weights, springs, and stops in your distributor. Then you will want to tune your vacuum advance.
I want to learn this.
Hopefully this is a good, helpful start for you 😎 We also have another good free lesson here using gasoline, but you need to learn how to tune with that before you tune using E85 or similar: www.hpacademy.com/free-live-lesson? - Taz.
where is the programm?
Do you guys cover email tuning also?
Hey Joseph, you need to learn the same things if you plan to remote tune, but realistically you want hands on experience before doing anything remotely. Even using your own low powered NA project for this experience is worth it.
TL:DR: Yes, but it isn't as simple as you might think - Taz 👨🏻

Ah ok im from the srt4 counity and e tuning is very popular i have a decent understanding on how timing works and a little about ve tables and trying to learn about injector scaling my tuner uses cmr and hp im currently tuned on cmr i have guides on tuning bht thanks for the input!
Though the information given to this course are excellent your accent is so hard to understand for a non English speaking person. Even TH-cam have difficulties translating you English in to English🤣🤣
Please correct this and I will definitely take the full course 👍
This is an old lesson, for the new ones we add manual captions. TH-cam autocaptions are crap no matter the accent 😆 - Taz
He kept saying 60 kpa what pressure does that reffer to
commie psi XD
It’s related to the throttle position angle
Can a car run on 100% ethanol safely as a daily.
Yes it can. In fact in some countries (I think in Portugal, but I'm not sure) it's used as a main fuel. The problem with running on pure ethanol is that you can't start a car when it's cold, so it works only in warm climates. Even in countries where it's used as a main fuel, cars usualy have small reservoir for petrol used only for starting a car in cold weather.
In Brazil is very common since 70's. Recently the cars started to use the heated injectors technology, so, there's no more need the gasoline reservatoir.
Can i simply increase timing in my load threshold during WOT say i have a minimum of 1.3 load at WOT and a max of 2.4 at WOT , can i up the timing from 3000rpm to redline between 1
3 and 2.4 of load until it knock and back it off and just leave the rest of the table the way it was and have only changed it wher it sits at wide open?
Should the ignition timing be advanced or retarded for forced induction engines
Hey Akash, it doesn't really work like that. Check out the free lesson series here, it covers ignition tuning: www.hpacademy.com/free-tuning-lessons - Taz.
Why the hell is there a anti trump impeachment on this video?
Was there an advert for that? Weird targeting. We don't control what adverts show where and when for the record - Taz.
