Thats right, not ITR, not p28 or anything else you guys will pm me about but a, 2000-2001 GSR ECU..
Really need this, my car is running extremely rich and not running well cause i have never changed the GSR mani for a single plenum one...


I can also use a obd1 p72 ecu
Not looking to spend much on the p72b, cause it only works with the 2000-2001 gsr...pretty much worthless
