N55 JB4 ISO E85 Maps? HELP!

jzingerman · 12-18-2012, 03:41 PM

I'm going to be installing the flex fuel wires that I recently bought from Terry and also updating the ISO firmware today. I'm curious as to what map I should be running once I finish up. From my knowledge, should I be using map 5 or is it possible for me to use map 7. I'll be using E85 and 91 octane. Also how much E85 should I fill my car with?

Thanks for your time and help

You are going to have to figure out what mix works best for you, some guys run a 70/30, some a 60/40. Just depends on conditions. Yes, use map 5, after, send a log to Terry and see if Map 7 would be ok. Depending on temps, and timing and AFR, sometimes Map 7 is ok.

Terry told me to start at 50% E85 with open loop set to 50 and get some logs in. I'm sure hell tell you the same thing but best thing is to email him directly. GL
