Thread: weird Calum base tune ecu

well i have a calum base tune ecu in my car set for 4bar[59psi] and 300zx maf 7psi stock, my wideband shows 10s as soon as i get over 4k.. anyone have this with a basic tune? at idle i get a good 16 reading...

Whats the afr like at idle? It should be high 10s low 11s under boost.

Sounds about like mine was under boost. I'd have low to mid 10's under boost. Ended up advancing the timing a little bit as it was too retarded.

at idle its 15-16afr

Then you are all set!
