So you may or may not know my wagon, 4G63T RWD swap, stock DSM harness, stock DSM ecu, stock DSM electronics
went out and hooked up the logger today because I've had a sneaking suspscion that the CEL was on, since i dont have one hooked up, i didnt have a means of knowing. I did however feel like the car had timing retard in boost, i had been not getting on it since the swap, i mean, i barely ever get into the throttle but the few times i have, i have though "this thing is gutless" and it feels like timing retard, well first i thought it was the lifter tick, which turned out to be the hydraulic lifter failed. replaced that, no more tick/rattle, still no guts.
Hooked the logger up and it shows my timing at idle to be 5* seems normal enough, rev the engine and the timing doesnt move, this concerns me.
take it out for a drive, timing is LOCKED, FROZE, SIEZED at 5* all through the RPM band, regardless of TPS, regardless of boost level.
I'm supposed to drive this car to shoot out next weekend, so of course now im bugging out.
I unhooked all the sh*t and checked the base timing diag port under the hood, it had connectivity to ground for some reason! i must have screwed something up in the wiring harness when i made it! /ubbthreads/images/graemlins/banghead.gif /ubbthreads/images/graemlins/banghead.gif /ubbthreads/images/graemlins/banghead.gif
So i went to the ECU, pin 12, Ignition timing adjust and cut the wire, figure i can do a short hand diag and see if that fixes the problem
start it back up, STILL LOCKED AT 5*
another weird thing:
When the car is off but the MPI switch is on, fuel pump running, ECU powered, (my ecu and stuff isnt hooked to key, just a switch) i have code 22, CAS
however if the car is running, the code is not active, just stored, i assume it has something to do with how im powering the ECU but the engine isnt turning. IDK, im dyin here.
Anyone have any help, i will try to swap the CAS this week but it's on the back of the engine against the firewall, soooo.... that'll be fun....
