Fully appreciate the research into this. If it was me I'd just go for the flex fuel kit and full flex fuel tune so I can run whatever gas I want and get the most out of whatever percentage blend of E it currently is.
Yes youre right! But this is a safe and reliable way to gain 40hp+ without voiding warranty or having the car tuned. If you live in california a flashed ecu wont pass
Tried this and on my 2nd tank of mixing 4 gallons e85 and pump 93. so far no issues, car feels more consistent and with a little more pep. Thanks for the video and all the info
@Dardantuned gotcha. thanks for the info. I really do like how the car runs with the mix. probably the best mod out there, free 40-50 hp you can't beat that.🔥🔥🔥
You mentioned doing this while running a stock 91 tune. What if I run 93 and have a Diablosport canned 93 tune? Would this work the same and still be safe? Still same ratios? 5 gallons of e85 and rest to fill the tank?
No, these cars run open loop at wot and run very rich. Adding ethanol allows it to lean out a bit and doesnt go into cat over temp enrichment. Fuel trims adjust part throttle. Too much ethanol will throw lean code. This mix doesnt, i run it daily
Add up to e30 and youre fine, but up to e25 if you want to play it safwr. You can log it and dyno it if toh would like! If you dyno it tell me before so i can help you remotely!
Enlighten me how is it dumb? Something that’s better for the motor is dumb? Ive been doing this for years! I can tune it on e50 and makes 100whp more but say you got a stock z06 without a tune you can mix up to 4 gallons of e85 for full tank and will gain 40whp+ and be safer than just running 91. Afr was 11.6 and these cars have low and high octane tables for a reason
@@americanpatriot9812 go ahead and do testing for yourself, if you need any help let me know! Put the car on the dyno if you want and test it so you can see afr and hp on your own

Was that full tank or half tank with 3 gallons?
@Dardantuned i pumped 4 gallons E85 first then the rest 93. is that a good ratio?
@@jonathangiraldo2598 if youre gonna fill it up do like 5 gallons of e85 if you do half tank do 3.4 gallons

So this only works aslong as the long term fuel trims can cover and keep the afr under 12s? Of course without flex fuel or tune

@@Dardantuned got it!
Would I still see gains from doing this even tho I am at sea level and have access to 93 fuel?
Yes of course! Test it witb draggy especially on a hot day! You can log it with hptuners as well
@Dardantuned thanks for sharing your experience. Do you think it would be safe to do it with being full catless and have a drop in air filter?
@@z06cam31 yes of course, just follow what i said! Nothing will happen, worse case you will get fuel trim too high code if you put too much
How much E can you safely add doing this? Like e20?

Just dumb to add ethanol without tune the spark tables for ethanol...

@@Dardantunedand you don't have to do any tunes to use that type of fuel?
@@americanpatriot9812 nope! These cars have two octane tables, they will add timing in its own
@@Dardantuned very interesting. I have a stock c7 z06 & this video caught my attention. Thank you for sharing
