Nistune Forums

I'm new to Nistune and in the process of building an "SRed" KA24DE soon to be KA24DET for my Datsun 510. I've opted to go with GM 6.2L E85 injectors P/N 12609749 @ ~525cc/min.

I've pulled this table from the GM tunes but I'm wondering which latency to use. They all seem reasonable at ~720-790us. I have not switched the injectors out yet but the car is running with the SR CAS disc and SR Nistune with R8 coilpacks.

Is there an optimal latency I should start with based on those values at 14V or am I splitting hairs?

Thanks in advance for the help.

About 790uS is a good starting point. I normally start them at 850uS depending on injector size and after I've established base mixtures (stoich at cruise with near 0% fuel trims) I then adjust latency to get idle running nice

Thanks Matt! I will do that once I get back to it!
