Here’s one... I’m tuned for E30 via Stratified and looking to go with the HPA HPFP (I have maintained all my stock parts intact so that’s the draw to the HPA), can I run E85 on the E30 tune? Forgive my ignorance if I missed this in this thread.

No you will need a retune

Copy that, thanks for the quick reply!

Can you install the Autotech HPFP and use your existing E30 tune?

The tune has to be adjusted for the HPFP. You will have fuel pressure spikes if not.

Anyone here run 100% pump e85 with Eurodyne and have a lumpy idle, the power the car makes it worth it but it is annoying.

Do you have correct hardware and software?

 

[Caughtbycops]

Yes, only downside is the idle, tuner contacted eurodyne and have no new updates for E85, was jus wondering If anyone else running 100% has the same issue

 

[Diggs24]

So, if you put pump gas in the car it clears right up?

 

[Caughtbycops]

When I switch to the pump 93 map it idles normal. You can’t just go back and forth with fuel with eurodyne without changing the map. I don’t see too many 100% E85 eurodyne guys that’s why I’m asking, I

What does your lpfp table look like for idle pressure (far left 0 column)? Is it same for both tunes?

Can anyone tell me if PR 305lph LPFP is enough flow for E20 fuel @28psi boost?

You'll know when you see pressure drop in your logs. I think it will be fine on your TTE535.
