S.O.S. P28 heat problem SMOKING! ANY IMPUT WELCOME
i installed my p28 and chipped it in my garage a while back, skip to yesterday everything is buttoned up
im taking power from the cigarette lighter for boost/oil gauges, grounded onto bare metal. the wideband got its power from the ecu (and since it im going to datalog it just made sence.) the gm 3bar is in conjunction with the current MAP and is spliced in not replaced. and im powering the boost controller through the dimmer switch, and i dont think it was a bad idea. ive read about it working fine but anything is suspect here .
so when we tried to start the civic we turned the key, then to on. after a few seconds solid CEL...expletive.
-possible problems
*poor wiring.
*poor soldering
*incorrect ground/relay
* (i had about 3 different kinds of wire one was pretty large too much power?)
but maybe its the Ostritch i got from MOATES it went bad on my friends Si and he had 2 P28s with his ostrich handy. (he came prepared lol) so we swapped out my ostritch with his and the CEL went away (bad ostritch GREEAT) we turned off the car and just to make sure it want my soldering we put his p28 in and set it to on. no CEL, but the ecu was SMOKING! shut the car off and slapped in my p28 to we wouldnt break his. attemped the same thing with my ECU and sure enough after the key was rocked to ON it would just heat up
^^this is the problem^^
i figured it had to be something wired into my ECU possibly one of the larger gauge wires, so i disconnected the wideband (only thing wired into the ecu) and retured the 3 harness clips to stock.
rocked the key...SMOKE.
took out the dash. disconnected the wideband, gauges, and boost controller solderd up all the connections to stock...rocked the key. SMOKE
any help as to what might cause this?? all of the people i know say its wired up correct and ive checked the manual HT for everypinout i can find and they all thell me im right... WTF??!
PLEASE HELP ANY IMPUT IS ****** GOLD TO ME
and my friend"hot wired" it to see if it was maybe the starter...nope cranked.

Last time I saw this, it was messed up injector wiring/low impedence w/o resistors.
I have some of these in stock if it was the 2SD1780.
I only found one vendor in america that had any, so I bought them all.
$20 shipped, I take paypal.

You have the purge solenoid plug on the harness swapped with the IAT sensor. There's a good chance your IAT sensor is trashed too.

swap the IAT and the purge valve plugs... better yet cut the purge valve plug off when your sure you got it right so you dont **** it up again...
both the purge valve and the thing on the board you smoked are EXTRA, will run just the same without that ****... but cut whats left of that thing off the ECU, cuz they ****** smell...
