I expect for the most part that these are the final settings for e85
Right side of the latency table
3.312
2.904
2.304
1.464
0.96
0.696
0.144
Scaling = 886 or 914 depending on which station I get my e85 from.
These injectors now have perfect manners for me including single crank starting which I never had with stock or evo injectors. What strikes me as different and is probably the reason that many people have problems with these injectors is that you cannot rely on only the correct deadtimes and scaling to make the car idle and cruise nicely. In order to get past the ugly part of their flow chart and keep your pulsewidths wide enough to avoid pintle bounce which will make 1.2-1.7ms pulsewidths richer than 2.0ms pulsewidths you'll need to adjust either SD settings (mapVE and rpmVE) or the MAF comp table to help control 0-60 load under 1250 RPM. Expect that you'll need to increase your asynch vs TPS delta as well by a substantial amount for throttle transients to not go lean and hesitate. I also modified a 1g fpr to fit a 2g rail. The lower pressure regulator was not necessary for e85 but since I had already bought the fpr before I had the injectors acting nicely I decided to put it on anyway in hopes that it will make pump gas tuning nicer if I ever am forced to do that. Until I am for some reason forced into running pump gas I'm not likely to update this thread with any pump gas experience beyond what I've already described which should not be taken to mean anything. I was using very much the wrong deadtimes and taking wild stabs at all other tuning aspects with the last gallon of gas in the tank IMO for cars that live in areas where e85 is plentiful these injectors are an awesome budget choice. I'm looking forward to reading about anyone else's experiences with these especially on gasoline.
