Need afr for 7 psi
It been a while since Ive been on the forum. But the old miata is giving lean problems.
I threw away the afpr, kept the bipes timing unit and got a TDR fuel tunner 3 (fuel management simular to Voodoo Box)
Running a non-intercooled M45 supercharged 1996 miata.
My afrs are 13.1 @ 7 psi @ 7000 RPMs. With 1.8L injectors.
I cannot get the AFRs to go richer. Guess the fuel pump must be weak.
What afr do u recommend for 7 psi.

Thanks, its good to hear from you 18 psi and everyone.
I thought 13's were fine, but couldnt remember.
i guess Ill change the fuel pump and shoot for 12.5 afr.
This little M45 gives a nice boost.... But its not extreme like a Garrett turbo.
The little controller should work fine for going back and forth to work and passing traffic. Lol
