Fucking sweet...

Well... I had an issue with my throttle shaft leaking vacuum/boost because of old dried/cracked seals. So, I took a spare throttle body that I had and rebuilt it with new seals. After swapping throttle bodies I turned the key on, opened up my gameboy (interface for DTEC tuner) and left the key on for about 3 or 4 minutes at which point I started to smell burnt electronics. Never started the vehicle. Turned the key off, disconnected the battery and found some smoke under the dash by the PCM. Pulled the PCM and took off the cover to find this...

After talking with some people I have come to find it's a driver for the ISC (Idle Speed Control). Tested my ISC and found low resistance in one of the coils which inevitably resulted in the smoked ECU.

I guess I should have swapped all the old sensors over from my original throttle body.

This comes at an absolutely perfect time because I'm set to race in a tournament which I'm points leader for my class on Friday. Final race of the year. Looks like that won't be happening.

mitsubishi never hear of fuses?

Alot of control circuits from the ECU aren't fused because they have a low current draw. Most vehicles are like this.

My bud may have a spare DSM 4G63T ECU, but I dunno how much good that'd be to you because it for an Auto car... Let me know if you could use it, He would probably give it to you for a baconator AKA cheap.

ecu suck on dsm, the previous owner to my 93 had to change the capisitors on my old ecu becuase they were known to leak

That's been a known problem for yeeeeeeeears. If they're caught, replaced and cleaned before anything happens then there's nothing wrong with the ECU's. They're actually pretty decent.

thanks for the offer! You're right though, an auto ECU wouldn't work correctly without being re-chipped. I found a guy that specializes in the stuff and I'm going to have him tweak it a bit while he's at it.

Shit man, you too?!?! That is a known problem on the 3000s too that burns out one of the EEPROM chips. I'm currently dealing with a limping ECU because one of the 3 caps leaked all over the board and ate up one of the circuits. It runs, but there's a few issues its causing. I replaced the one cap that leaked and left the other 2 temporarily. I need to buy a new ECU then I'll have mine rebuilt.
