I ordered HP Tuners. It should be here tomorrow. I want to tune the car for an e50 blend because i have e85 available locally, and I have KR on my current setup. Once I get some bigger injectors, I will go full E85

Currently im running a blend around e30. and im still seeing KR. (mods: DP, 3.5, 180tstat, K&N drop in, Autolite 104s)

What I am trying to figure out is what to do first.

1. use the method in the Ethanol tuning guide to set my fueling ~115%, THEN work on tuning the car, dialing in timing, fuel trims etc.

Or

2. Get the car back on pump gas, deal with timing and fueling, THEN switch it over to e50, and fiddle with timing etc.


FWIW, im seeing ~3* KR at wot, and some odd spikes at lower boost/ rpm. on pump gas 93, im seeing 7-8
