s14 sr20 in limp mode

[drpimper746]

i am finished with the swap and the motor is in limp mode. my check engine light is not coming on either. im trying to figure out if its the mafs or the ecu. anyone know anything to do.

If it won't let you rev past 3000K or so, it would be a bad MAF or a bad MAF connection

Make sure you didnt cross the signal wire with the power wire in the MAF. Could also be a faulty MAF unit. Goodluck

i think i found the problem. i ma using a ka24de mafs and u can only use a z32 or a s14 sr20 mafs. well see.

You can only use the maf designed for your car, unless you use e-manage, AFC, power FC, or some type of tuned/reflashed ecu.

Did you try running the codes at the ecu?
