computer code 15 and Superchip

[tomazzzo]

Has anyone expirienced any problems with superchips making the ecm send a code 15?

I pulled my ecm computer out of my 93 lx due to a code 15--rom failure to find a superchips module connected to the computer. Now I am wondering if the chip is supposed to make this code 15, or if the computer is really bad. Im going to try to put the computer back without the chip, but I wanted to see if anyone has heard of this.

Thanks,

There was a Ford TSB out awhile back but this was for later years like 96 and above OBDII cars. Something like code 600 rom failure and it stated check ECU for aftermarket chips and remove.
Didnt know you would actually get the code with earlier ECU's. I had a JMS chip in my 93 and it worked just fine. Where does yours plug in. Service port on the side? I could see getting it that way. The chip may just shut the original ROM down and thats how it gets its strategy into the ECU w/out it relearning a way around it.
