650s 2g MAS and old skool 5 knob problems
 

I am running a 2g MAS, 650s, and a 5 knob safc to correct it out a little in a 1g

First will this combo work? I turned down the fuel pressure a little but even though the 5 knob is a little crude, figured it would work.

However I am running RICH. It will start right up but after that the AFR just peg to 9.6. I am getting a check engine light that turns on and I am wondering if I am having a MAS problem. Do they go bad? Are all 2g MAS the same? Maybe I didn't get one from a turbo car...

what CEL you getting. are you sure you wired the afc in right. and props to your for going old school

Re: 650s 2g MAS and old skool 5 knob problems
 

Ok, I rechecked the wiring on this and it was wrong. Fixed. (stock boost gauge works!)

Still running rich though...

Boost leak test time

I don't know which cel it is yet. I am trying to get my palm working. Check engine light still comes on now but not right away.

i cant remember but is there any of those small switches on the back of te 5 knob to switch it to a karmen sensor, with 4 cylinders or whatever

I made sure that the switches and the dial were in the correct position. That was one of the first things I checked. Set it up according to the manual. Unless the manual is wrong or there is a secret I don't know about these switches. I don't know what each one does...
