I just tried to install a GForce ECU in my 94 RX7, and now it won't start. The engine tries to crank, but it just won't turn over. Any help or suggestions would be greatly appreciated. Thanks. Russell.

 

I just put the stock ECU back in, and everything works fine. Do you think that I might have a bad ECU?

 

I bought the GForce ECU used, off www.thepartstrader.com So I still have my stock ECU and the one that has been remapped. However, my stock ECU has a sticker that says N3C1 on it. The GForce says N3A3 on the cover. Would this difference matter at all? The battery was disconnected when I installed it, and i'm pretty sure that all the connections were solid.

 

Also, with the GForce ECU, the Check Engine Light won't come on with the accesories, but it does with the stock ECU. This is so damn frustrating. Thanks for any help.

 

have you contacted the guy that you bought it off of???
