R32 Gts4 ECU burned Resistor...advice

Quote

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.

oooh, 

well i would be of the opinion that once an electrical board has released the magic blue genie its best to replace it. i would get a new ecu

I would love to, however finding an ecu for a Auto Trans GTS4 in the USA is proving to be a challenge.

Does haltech have the A/T control?

Replace the resistor and see what happens
