Romraider has a nice little tool for scaling injectors and adjusting latency that works pretty well. They also have one for MAF scaling. I really wish they would start working on Evo tuning integration. The possibility is there...
Yup, thats how we do it. I start 15% lower than actual injector size, and slowly work your way up along with adjusting your latencies. I hate doing injectors though, Im not a very patient person, and you need to be patient with injectors. I found a website that has the different latencies for different injectors and Ive found it a good starting point. I use Evoscan, Logworks, Scantech, and ECUflash for everything I do. The new Evoscan 2.6 is pretty good now. It does the same as before (datalogging) and now it does CEL reading and clearing them, and it does the same thing that Logworks does, so I dont even use Logworks anymore.


Sean, I wish I could use this on the LS2, but my current cable doesnt even work on mine for anything. The new cble would work for checking CEL codes and clearing them, but no one has even tried to crack the ECU for this purpose. I really would like someone to give it a shot.

Boost, because sometimes atmospheric pressure just isn't enough.
