AKWRX, thanks for your reply. Can I ask what the ratio of alcohol/water injection to fuel is on the car that you mentioned?
I'm not really sure where to proceed from this point. My concern is that my EGTs approach 1600 F near redline with an AFR of 11.1-ish (on wideband), with water injection. I would like to lean the mixture out but my EGTs are high enough that I don't think I have any room to move. Can you suggest a method of safely moving to a leaner mixture?
