As far as your timing goes, I run 17 around 7k and 16 around 8k and 15 at limiter. I made power with an extra 2* in there, but right above that was when it started pulling timing due to knock retard. So I backed off a couple degrees

 

I need to drive my car to the tuner next week. Can I put gas in my car with E85 tune and "granny-drive" to the tuner?
Or is it better to use some sort of base tune to drive to the tuner? Is there any one in the Flashpro?

If I take it easy i guess that my map-sensor will adjust the fuel?

 

BTW its 70km to my tuner

 

It's going to run very rich but as long as you stay in closed loop (granny drive) the ecu should compensate most of it.
Lycka till

 

Thanks man!!

yes i am getting around 1.8 volt of knock around peak tq i wonder if the water/meth and 80f iat's had something to due with it either way i will take some out and i saw 20 degrees after a few pulls due to belt slip i was falling to 8.5 psi and i had timing a bit aggressive

 

Got my car tuned yesterday.
352whp and 300wnm happy with the result and the car pulled great.
Saw 360whp+ but that was with to aggressive timing so we backed of a bit.

Today when i drove the car had afr 10.3 under WOT and that is not how we tuned it.
Tuned about afr 12-12.5

Why is this? Just got from good to bad over night.

I got some misfire today as well under low trottle. Dont understand?!

 

Hows the temperature outside compared to when / where you had it tuned? misfire at low throttle sounds like a tune issue as well, what were the AFRs when that occurred?

Are you sure you had the e85 completely out of your tank? If you had some kind of mixture in there still of pump and e85, when it finally cleans out to straight pump, you're gonna be running rich

 

Im on the same tank of gas as when I tuned it. So that will maybe happen but not yet, i guess.
The temp outside was warmer yesterday than when I tuned it.

The missfire was about AFR 15 and LOW speed with almost no throttle at all.

This is so weird... Can someone send me a pic of the fuel pump install on a AP2?
I will take a pic of mine when I get it out, but i don´t think that´s the problem.

Is it the pump that have a problem with the returnless fuel system?

BTW, this is the dyno. The car pulled without problems on the dyno:

I assume this is on the AEM EMS? Its surprising how much temperature effects the AFR but I wouldn't expect it to make that much difference. The misfire at low throttle happens where there isn't enough fuel at high vacuum positions of the map. What I do personally is add abit of fuel in those areas and then let the wideband feedback trim it back. That way you have the fuel when you touch the throttle but it wont run rich for ages and ages as the o2 will trim it back.
