okay so recentally i had to replace the rack and pinion in my 2002 wrx. it is a 2.0t with 5spd manual. while i had the rack out i started buying other parts and kinda doing them while the car was up.. so got the car back together and it RAN GREAT, sounded good, idled good, smelled good(lol) and everything. one of the items i purchased was a wot box. for those of you who dont know its a electronic box that when wired in allows you to have two step(launch control) and be able to wot shift your car without doing as much damage to your already sensitive tranny. the install went like sh*t, every wire the diagram said to use was absolutly wrong and eventually i ended up getting online and usuing the wrx ecu pinout(which i shuld of done in the first place)/(or just not of even bought the pos in the first damn place). so i finally got it wired in correctly but my car ran horribly.
While driving it is like the turbo was removed, the car has no pull and will not rev over 4500rpm. basically in 4th wot the car is struggling to do 65 mph.
checked rechecked rechecked and even re did all the wiring that i taped into the ecu. ( what i mean by that is i undid the wiring into the ecu from the wot box, and rechecked all the wires i cut that were the wrong ones from the stupid diagram)found that a red wire with a white stripe had been cut(previous owner) and this just so happens to be the wire that tells your car you have a cel.so i rewired that and the car instantly came up with a cel( by the way the whole time i was working on the ecu i had the battery unplugged and removed as well as afterwords while trying to recheck) so i borrowed my friends scan guage2 and read the code(only one) which is surprising because i have a tbe, intake, and other things that i would think would show a cel. the code that cam up was P1560 which is back-up voltage circuit malfunction
Whith that being said i have looked this up on many subaru forums and google and everywhere i could think of, i have tried checking the fuses under the hood, i re checked all the wires off the ecu to see if any were loose or being grounded, i tried having a ase tech on just answer help me, and im just stuck. i really love my car and i want to be able to drive it again im just lost. i dont know if i should buy a new ecu and new wiring harness or if there is a simple fix or what but i would really like some help. Any help is greatly appreciated
