just got an 98 evo 5 GSR with brand new PFC L Jetro and hand controller
ver. 3.05B,FC commander 5.01A the Model ser no : PFC CP9A5 020 - 0400.

I don't hav an English manual for it. I want to set it up in my car. I have a built 2.3L Motor, stock turbo, stock head, stock cams. 750cc injectors, walbro 255 pump, 3 inch exhaust.

I want to set up the power FC and run my 750cc injectors. But in the Japanese manual why does it use 590cc injectors as stock when evo 5 stock injectors are 560cc not 590. Is this a mistake or is there some reason for using the # 590.

So far I have scaled the injectors using the calculations
590/750 =0.786 and 0.786-0.66=0.126msec
but it should be 560/750=0.7466 and 0.746-0.66+0.086

My car drives ok. it hesitates a bit though when just lightly pressing on the throttle. The car doesn't stay idling on start up unless warmed up or driven for a while first.

Im totally new to the power FC and need any or all help I can get.

whats the best way to go about tuning. I don't hav a datalogit.

and is there anyway to get launch control on this thing. As I plan on doing some drag racing. I understand power fc's don't hav it. but read there is a program called FC CO pilot that gives you these functions.

My future updrages would hopefully be a GT35 or td06sl2 20g or 25g turbo
