E85 usage with JB4

Just recently bought a JB4 Bluetooth kit for my 2022 Limited Hybrid. Planning on making a installation video along with initial impressions. Paired with that I noticed a ECA kit from FuelIt which I have ran on my Audi in the past. Curious if anyone has experience with running E85 and noticed any power gains. Purely interested in the option for fun when offroading and towing. Thanks in advance.

 

I am not familiar with the JB4 but you wont make much more power unless you advance timing and raise a bit of boost when running E85.

 

Ive been running the Fuelit kit since it came out...actually got it before it came out, helping Payam with some r&d. Before that, I was guessing E content and hoping I was close. No issues with the kit, never skipped a beat so far.

Def a power gain on map 5 and E30. Pair that with tow+ mode and youve got rolling burn outs from 25-30mph.

 

Sounds fun! One thing I noticed with the JB4 is that it reads 12 PSI of boost under map 1 with the App. However, the gauge cluster boost levels are reading around 18PSI. Unclear which is more accurate ha.
