E30 Tunes? 034? IE?

[Rex32]

I’m currently enjoying running E30 fuel mix in my B9 SQ5 and want to pull the trigger on a full ECU/TCU tune while both 034 and IE are having sales.

I can’t find any definitive info on E30 tunes from either, ChatGPT says IE has one but I can’t find it.

Anyway, can anyone shed some light on this?

I know this isn’t the correct forum, but it gets a lot more eyes than the B9 SQ5 one.


Thanks!

soooo you are running e30 without a tune? thats a bit risky. not sure the OEM calibration can correct that much leanness going on.
i havent seen either of them run an e30 tune, its either full corn or e60, which is what im running.

iE supports any blend from E0 to E100 with their TrueFlex kit.

IE probably the move w/ flex fuel & ethanol blends based on the research I’ve done.

I’m occasionally running an e30 blend w/ JB4 custom tune on map 6.

JB4 can do e30 but I wouldn’t go more than e20 (~2gal e85) without a tune or at least piggyback
