I was up at 430am chasing a hunting idle in an e30 and came upon this magical vidya to get it sorted. Thanks so much, man, The whole neighborhood is a lot happier
Man the block of identical VE numbers in the idle range is so obvious after watching your video. I can’t believe I was trying to do a sloped VE across that area. That explains why my AFR was always jumping up and down as the idle finds its happy place
Your videos helped me a ton with my Kdata powered M20b25 E30. My car was running a high idle and erratic AFR's. Turned out my PWM table for the iac was at like %70 open across the board. I tapered it down to about %30 at target temp and it runs awesome now. Thanks so much!
hi, thanks for all your videos, i'm trying to set my IDLE on my ITB Motor, 1.5 Mazda e-series engine, did you think i could use this tips on these one?
THANK YOU for this video , I was so confused on how to get the engine idle smooth. I am working on JEEP 4.0L but I am using Speeduino(sorry) not the MS , Thank you very much for this video 😀
Well i have an idle issue mine doesn't hunt it sits at 1500 then just starts dropping rpms and shuts off unless i give it throttle input. trick is its definintly not a stock car. its got upgraded cams 264/272 with a holley ls intake and a gm 95mm tb on a 3.0l v6. It's an older batch-fire ignition.
Thanks for the help on this, good video. I've been trying to get my mustang to idle without hunting, it's been a pain. It seems like a lot of people are getting away from the Megasquirt platform for the Holley. You're videos are helping me out, thank you so much.
Unfortunately it’s getting harder and harder to get questions answered in the Microsquirt community. It takes days to get facebook and forum posts approved by the admins and by then I’ve usually watched a video (like this) and figured it out
Great info! I am tuning my first car, a 99 miata with a supercharger targeting 200hp. That aside, your ignition table is giving me confidence. All I've ever known is that we want 10-14 degrees advance, and now I am understanding that is a base figure ("x"). Still, 16 degrees seemed intimidating to me, this is on my base map around idle.
Hi mate, I know you posted a long time ago. I’ve got a 96 with a supercharger and I’m having problems with start up and idle. Needs revs for start up every time pretty much. Wonder if you could help me out?
Sounds like you need to increase warmup or afterstart enrichment, if it only happens when cold then likely part of the startup process and not a problem with idle. I have a 96 turbo with big injectors and needed about 30-40% more fuel on startup @@RJ-dr8to
Idle table at 10. Idle control adding +3, add advance 13 at 500 rpm. At 500 rpm will timing be +3 +13 =16 timing? Which will have it spike and overshot the normal idle?
Any particular changes to this method if my car is running on e85? My miata currently idle hunts and especially after being warmed up it revs itself up to about 2-3K RPMs and sits there. I've also noticed idle hunting become worse when my radiator fans kick on. Kind of awkward and don't know why but would love some advice on that!
Great video. I’m looking forward to adjusting mine. I find that my timing table jumps from 14 to 24 at low rpm and when I try to accelerate and disengage the clutch it will typically stall. I will work on the VE table and then adjust that timing accordingly.
Check where your duty cycle is set on. I run the icv test and use that duty cycle where it idles on my table. If set below the car wanted to stall out on deacceration.
I am going in circles, The idle is either not working or too high. It can be this from run to run and also in the same run. What I dont understand is when you do this with idle control end EGO disabled, you have to turn the screw on the TB to let some air in. what do you do then, when you want the idle control to be enabled again?
My engine has a cam and the kpas and fuel idle up and down in kpa cell 75-80 is that normal. I didn't mess with it long . The AFR gauge says 10:1 to 11:1. Took 1 plug out and it was black
I can't start my car without the idle air control turned on. It immediately sputters and dies. Is there a way to have it so that it can run without the idle air control on for the tuning step you mentioned?
Go into open loop. Keep adding fuel and like small increments..if at 34 go 36. If u go to high all the time u will never get anywhere. Then after open loop is good. Then close loop. Keep ego correction off for a few months.
think you have to add fuel in the air temp map compensation, I'm about to do this on my Datsun as when I shut car off for 10 minutes and restart, its super lean AFR as the intake is cooking the air and fuel.
@@TurbineResearch just to confirm also I have spark A 1-6 spark B 2-5 spark C WLED with 1k resistor 3-4 I have two bank batch injection (what 3 cylinders should be tied together?)
beware also, that 10 BTDC that as rpm lowers 10 degrees advanced at 500rpm is a lot more advance at 500 rpm than 1000 rpm because of piston speed is slower
@@TurbineResearch my idle never really stumbled i was really just after rpm the ignition advance did bring it up but i did have to add quite a bit of advance
Stay in open loop till it runs perfectly. Once this is reached..even at higher idle then go close loop and adjust idle table. If starts oscillating at idle go back to open loop. Lower timing to 10 usually will drop the idle down for u. Then add fuel till perrs then back into close..ie due all your tuning in open then close loop to run
Another way of doing it if you want a good idle fast. Tune it for as much vaccuum as the engine can pull at idle as possible. Afrs at idle isnt that accurate and dont have much to do with a good idle.

It helps the idle a lot especially when first starting out . Glad it was helpful!

Really good video.
This will come in handy once I actually get my car to idle.
Thanks for taking the time to do this I'm new to this and u helped me understand a lot
Wonderful video thank you so much
Thank you!
Great video, thanks, subscribed for more MS content. I swear idle and a good cold start and the hardest things (at least for me).
Thanks ! Idle is difficult and takes a lot of tweaking and trial to sort out
Awesome! I’ve been dealing with a slight surge lately

You could probably do 10 episodes about start and idle. Many, many parameters. Thanks for doing these videos
Absolutely it’s the most time consuming part of the process
Nice channel bro. Keep going.
Thanks! Will do

Hello .After making these changes and turning the fuel correction back on . Will that fuel correction change these numbers tha where set? Thank you
Cool stuff, definitely following up on any future videos. I'd like to run MS for my m30 cars so this will be helpful getting started!

Thanks man that’s good info keep humble
My miata idles is pretty low on cold starts but goes up as the car gets to operating temp. Do you know what it could be? Thanks.
Do you have an idle valve ? If so you can increase the idle duty and get the revs up with more air
I can't start my car without the idle air control turned on. It immediately sputters and dies. Is there a way to have it so that it can run without the idle air control on for the tuning step you mentioned?

U might be running on a minus cylinder too.
ur the fuckin best dude. i was chasing my tail for a long time but this really set me on track.. any tips for getting a car to start after heatsoak?
think you have to add fuel in the air temp map compensation, I'm about to do this on my Datsun as when I shut car off for 10 minutes and restart, its super lean AFR as the intake is cooking the air and fuel.
Hmm i see you have a e28 what angle deg BTDC did you use?
Are you talking about the tooth angle in the initial setup ? 87deg or something like that just check it with a timing light to be certain
@@TurbineResearch just to confirm also I have spark A 1-6 spark B 2-5 spark C WLED with 1k resistor 3-4
I have two bank batch injection (what 3 cylinders should be tied together?)
@@michaelcleary5205 that sounds correct 👍batch injection can be 1-3 and 4-6
@@TurbineResearch so 1-3-5 2-4-6 i get it to idle just really rough 12.4 afr going to double check the timing!
@@TurbineResearch so it's runs like a cammed car and is very rich but alot of hesitation and smoking 🤣 any suggestions
beware also, that 10 BTDC that as rpm lowers 10 degrees advanced at 500rpm is a lot more advance at 500 rpm than 1000 rpm because of piston speed is slower
after getting it running do i leave the idle control off ?
You can turn it back on and tune the idle control valve separately
@@TurbineResearch my idle never really stumbled i was really just after rpm the ignition advance did bring it up but i did have to add quite a bit of advance
Stay in open loop till it runs perfectly. Once this is reached..even at higher idle then go close loop and adjust idle table. If starts oscillating at idle go back to open loop. Lower timing to 10 usually will drop the idle down for u. Then add fuel till perrs then back into close..ie due all your tuning in open then close loop to run

What program you use for tuning?
Tuner studio
Another way of doing it if you want a good idle fast. Tune it for as much vaccuum as the engine can pull at idle as possible. Afrs at idle isnt that accurate and dont have much to do with a good idle.
Not a good idea. The idle table has nothing add if it need timing.
