I'm hooking up NOS wet 70 shot on my NSX and I just want to do it right and safe

I don't have fuel pressure guage yett and I need to know what is the normal fuel pressure on NSX. Idle and over 3K rpm's. Does any one know ?

I got the automeater air/fuel guage but I don't know where to hook it up on the ECU. Does any one know the pin that is sending the signal to air/fuel meater? I know there must be two. Right? One for 3 cylinders and the other for the other 3 cylinders.

Thanks for your help in advance

Factory spec for fuel pressure is 48-53psi, I believe. This is measured at the rail with the vaccum line disconnected from the FPR and clamped.

As for the A/F gauge you have from autometer...it's just for show...not very useful for tuning. To tune, I'd put the car on a dyno with a wide-band O2 sensor. I'd get a digital EGT intstead...

David B. will have more useful information about how to proceed from here, so I'll leave it to him to chime in...

I just want to be sure that I'm not running lean. It just makes you feel more conftible if you see it

What is a wide-band O2 sensor, and what is digital EGT ? I never heard about it.

Thank You
