Got my S14 ECU today!....STILL won't run right

[brandonlgilbert]

I received my stock S14 WC ECU today. Put it in, cranked the car, and the damned thing still will not rev past 2500rpm. I am almost ready to put the working end of my SKS in my mouth over this sh*t!

We're gonna try the CAS from my redtop tomorrow and see if that may be the cause. I really don' t know what else to do. My birthday is Saturday, and I really hoped to be shredding tires this weekend, but it looks like another dead end. So if anybody wants to come to MS this weekend and give me a hand, email me and I'll send you directions lol.

Thanks,Brandon

Sounds to me like you need to check your MAF. It seems that it's in limp mode.

[brandonlgilbert]

checked it. replaced it with an S14 SR MAF and still no change.

Didyou check voltages on the ECU and the MAF plug to see what it is sending to the ECU?

[brandonlgilbert]

I have not. What are the correct voltages?
