I need help flashing my ECU

[boostnhard]

Hello! Im having an issue doing the initial set up for my DSM.

Im using ECUflash and EVOscan. everything works fine. I was able to flash the latest ROM into the ECU but i just cannot set up the injectors, I have 720 densos, My idle is super lean, but when i drive the car is super rich. Mods list is updated.
which tables do i use to tune as I drive on low throtle and which os for the idle?
Is there a write up or something that could point me out in the right direction? or someone that has done this before. I need help

Any help is greatly appreciated.
Angelo

you sure about the mod's list? i just checked it and it still shows you having 950cc injectors and a SAFC for engine management in a 95... is this true? are you running a MAFT??? if not and you are using a 98/99 ecu then i would start by getting rid of that SAFC or at very least zero it out (all of it), it is doing you no good as of right now and just making things harder to tune... what do you have entered in ECU flash as your injector size and dead times? also it might help us out to post an idle log and a copy of the rom you flashed to your ECU so we can see what is going on, or at least a screen shot of those settings

You need to adjust your injector scaling and injector voltage latency values to fix your problem.

Latency values make a difference down low (like idle) and injector scaling has more of an impact under higher loads.

It's explained better here:

Go to the injector setup pages 65-76.

You have to find the balance.
