My E85 tune... thoughts? torque suggestions??
Ok guys i've been reading and reading for months trying to plan out my E85 tune.* I've been hesistant since my car is a DD and because i've been waiting to get some 1000CC injectors...* I still havn't bought them.* Anyway on fathers day night around 9:00pm i just randomly decided to give it a shot. My girlfreind daughter and I went for the drive down the 105 to the damn traffic jammed 405. I ran my tank nearly empty and ended up pumping 13.6 gallons of E85. i flash my ECU and car started up great. fuel trims where perfect and my AFR readings were spot on. logged the car all the way home with no problems.* started tuning and tweaking that night and i didn't wrap it up till 1AM. here are my graphs and charts. let me know what you guys think. the base flash was extremely conservative. and my current tune is unfinished. i just wanted some thoughts and opinions.
i am still using load based boost control. i will switch over to psi control after i get my injectors and new FP wastegate. Mods are in my sig.
besides my injectors maxing out its important to note that my wastegate is bent. so my boost falls way to flat at redline. im at 100% wgdc at 7000 and 7500rpm.
base is 24psi. minimal timing based off my 91 tune. my tune so far is at 27psi with much more aggressive timing. no knock.
the base graph is from my logs that night... the second from a log taken 2 days later day
evo 9 5 speed. 3rd gear. weight 3170. contents 340lbs. dyno jet. smoothing factor 6
thanks
