Ill post my mods in case they may be relevant. 2009 Ralliart, evo X turbo, evo X equal length header, high flow cat, 3" all the way back, CBRD intake, 4" FMIC, MAperformance UICP, 3 port ebcs, tephramod. I got some FIC 1000cc injectors and started with the values that came with the injectors. 860 scaling and the listed latency was .860 @14.08 volts. the base latency is 0 and min IPW is 1.280. I have been trying to get my trims close to 0 and at 860 scaling they went positive until 12.5 so i kept lowering the scaling to get more fuel and im down to 770 and it seems the trims still climb positive. did I miss something ? I read the thread on upgrading and tuning injectors, and it basically said I had to change scaling and latency, or so i thought. Any help would be appreciated

I think you need to re-calibrate the maf for the intake (Unless you already have). Find the latency/scaling posted somewhere on EvoM for your injectors, plug those in, and then calibrate the MAF to get your desired trims.

So before i ran tephra, I did work on the MAF scaling, it was way off with the new intake and turbo so I got it pretty close. After installing tephra, i maxed out my MAF table to run MAP. I actually think changing the latency solved my problem, the numbers that came with my injectors were not very close, I had to increase the latency a rather large amount and now im within +/- 6% which isnt perfect but shows im on the right track. but I think something is still amiss because anything over 20psi boost, the afr starts to climb enough for me to shut it down.. so i have to figure that out ... is there a place where all the stock evo X maps are that I can look at ?
