Leaning out on full throttle

[Rob]

Hey chaps.​

​

Got the micra running sweet now.​

​

I have cut the speed sensor wire to the ECU and ive noticed that still when im on WOT the AFR goes to 10.0 briefly but will then start to creep up, at about 3000rpm it works up to about 13.0/14 and then stops when it gets to around 14.0/15.0.​

​

If i only use say about 50% thottle or go WOT and then back off slightly it will stay about 11.0 AFR.​

​

Any ideas?​

​

Thanks Rob​

Underfueling eh rob, mine was the same and i could only give it half throttle, you need bigger injectors and less pressure at low throttle

Time to fit the SR20DET injectors then.

I have a rising rate FPR also where i can mess around with the pressures.

Will give that ago.

Thanks Frank
