    Engine can make more power, Had trouble keeping the auto trans in gear, was not happy with the power it was making.  Time for M/T swap.

    R32 Gts4 ECU burned Resistor...advice

    Ok, so installed the repaired resistor ecu, used  the injector nodes, injector is firing and the the problem is still there...definately no spark.  Since the harness goes to the ecu and resistors off the ignitor, i measured the resistance across the 6 pinouts..all measures the same except cylinder 4 wire, which read .02.  I need to do more testing, but does that imply that wire is being grounded somewhere? Can someone please test theirs and see what they get?

    let me preface this by stating I am no electrical guy.  I can do mechanical, but thats about it.  Anyways, I upgraded my turbo and injectors and then installed my Nistune ECU a few weeks ago.  The motor when fired up sounded like a wrx...found that unplugging coilpack #4 yeilded no change...boom, dead cylinder.  Pulled the injector, injector is fine....then thought to check ecu since it was just sitting on my floorboard...Burnt resistor that corresponds to cylinder 4.  Now, i dont recall disconnecting my battery before doing all this work, and am hoping that may have been the cause as i was moving a lot of stuff around and out of the way.  I am replacing the resistor, but would like to know what else I should be looking at that could have caused this, besides me being an idiot and not disconnecting my battery before doing all this work.  Thanks in advance for any tips or advice.
