Re: K24A Extremely Rich

Just a follow up. Injectors and their voltage checks out, dead times were cleared and reset to what the manufacturer recommended. Car still runs pig rich, reduced overall fuel trim from 30% to 10% and it did help some. I managed to fix the Analog Input from the AFR gauge as well, I grounded it to th...

Re: K24A Extremely Rich

That's a good idea, will check voltage to each one today. These are from a local Vegas racing company, DIYTuning702. Guess deciding to support a local business kinda bit me in the ass :/ The fuel pressure decrease and some adjustments to the dead times might be enough to get it to my tuner in a few ...

Re: K24A Extremely Rich

Ok so I got the attached sheet for the dead times, although they match what I have in there now. Is this just bad data altogether?

Also, checked my FPR and reset base pressure to 43 and that helped some...still sits around 10.5 at idle though.

Re: K24A Extremely Rich

That is interesting. Going to check this out today and maybe shoot the injector vendor a message about these dead times.

Injector dead times are for 310cc injectors not 1000cc injectors, so a minor change in temperature or voltage is going to throw off the fuel at low openings.
Really? Hmmm I input the dead times for the injectors I got according to voltage. That's how it's always been too.

K24A Extremely Rich

93 MR2 K24A w/Borg Warner S252 Turbo 1000cc Injectors / FPR @ 50psi GM 4Bar MAP KProV4 Dyno'd 11/1/18 - 334/300 @ 10psi The issue is that it is running WAY too rich at idle and low RPM. It was pretty rich when it was tuned, for safety, but it's gotten ridiculously richer. AFRs are deep in the 9s at ...
