1G ECU pin swap

[cheap90gsx]

after swapping pin 2 and 14 to use a 92 ecu it ran fine but the tach didnt work under boost. so i figured i would try to use better wire and better splices. after re-splicing the wires it wouldnt stay running and it wont drive down the road. was i not suppose to splice? could i have fried something from connecting the wires wrong??

you need to switch pin 6 and 14.. check vfaq.com

it starts up but wants to die when i touch the gas and if i dont touch the gas it dies. and when i tried to drive it was cutting out and wouldnt go very far.

You don't cut the wires and splice them, you release the pins from the connector and swap them.

Assuming your putting a 91+ ECU into a 90 car you can expect that the tach won't work correctly.

so i would probably need to pick me up a new wiring harness?

Not if you did a good job.

Yes its not that hard, you shouldnt need another harness, like steve said. I've swapped ECUs out before.
No problems.

Well I already cut and spliced the wires to the ECU and the first time I did it wrong so I ended up splicing 4 wires. Then I used different wire and connected two wires wrong and drove it.

I think I fried something because after I found what I hooked up wrong it did the same thing after I fixed it. And my DSM guy just told me he thinks I could have messed up the ECU.

Without you being specific about what you did it's hard to say.

With the addition of http://www.dsmlink.com/images/forums/1GECUPinout.pdf and http://www.dsmlink.com/images/forums/1GECUPinout.pdf to the links above, you have everything you need to figure out what you did.

All the wires are good now but I messed up and cut pins 7 and 23 then I connected them backwards and that's when it wouldn't run and I found pins 7 and 23 backwards. After correcting them the same thing happens as it did before correcting them.
