I have a slightly modified Mitsubishi EVO VIII, making about 320AWHP at 11.0:1 AFR at 20.5PSI of boost.
My problems are: Where I live I can't get any unleaded fuel over 91 Octane. My stock ECU, (which has been reflashed by a custom tuned Dynoflash), pulls timing due to detonation (stock knock sensor). I also live in Yuma, AZ. Desert! Hot as hell. In the afternoon, I loose about 3 deg of advance at redline (7800rpms).
After reading a little about WI, it sounds very promising.
Could somebody more knowlegeable on this subject guide me in this area?
Does anybody else have WI on their Evolution?
What system would be best for me?
What safety add-ons are required to keep me from blowing my motor.
( I have an HKS S-AFR to adjust fuel, I also have a WB O2 and datalogger, I can also get my ECU's timing adavanced from Dynoflash).
