Hello i'm new user ! :wink:


In my 300zx car i have installed:
555cc
Stock maf
Upgrade turbos

In my nistune i check 140 to 202 k constant but running rich 10:1 or more in fourth gear, but in third gear running lean 13,2:1 to stoichmetric ( can do this o2 sensor in high revs)
I reescale TP and down pulsewith to minimum possible but in fourh and fift gear running more rich.
I put 7,38 ms in fuel map but i see 15 ms injection.

Thanks

You might have to adjust your Injector latency too.

new or old style injectors ?

for the old model injectors I've had the best results by leaving the latency to the stock value (4B) and 205 as K-Value
