Tunning Question???

[Inprogress]

I have a big 16g, with 450cc injectors. I do understand the concept of keeping your injectors at less that 80% duty cycle, but how would you monitor this? I am going to be tuning with a NGK wide band, SAFC, EGT and a pocket logger. So my concern is not leaning out my car as much as it is over working my injectors. Any advice or knowledge would be greatly appreciated.

i think yoy might need bigger injectors and AFPR and a walbro or a supra fuel pump
(walbro more recamended)

I do have a walbro 255, I sold my 550's because I have a bigger turbo and I am waiting to get ALL of the other mods I need to support it. I thougt I could drive my car stock for a while, but it is driveing me CRAZY!

Sorry, The logger I am useing shows duty cycle. Should have look at the settings before I asked.

You seem to have all you need (logger and S-AFC) to tune.

BUT, since you said you have a 255lph fuel pump, you NEED to get an AFPR otherwise you're going to be running really rich.

Also, please update your profile to reflect your current mods.
