I got my ECU chipped,(92’ OBD1)And I was wondering, If I wanna change to a different chip, Do I have to swap all of the little parts again, or just the main board with the IC socket? ---

Well, if the guy who chipped it wasnt dumb, you will have a socket. All you have to do is pull the chip out of the socket and put the new/reflashed one back in the socket (the right way!!). Ben ---

My mans a PRO…and I was asking a simple question…Can I just swap the main chip in the IC socket to work? or would I need to change all the resistors and stuff too? ---

New Chip Obd1 Well, I just got a new chip and put it in the IC socket. I resetted the ECU like recommended. It was a SPOON chip off of Ebay. It says that I could rev to 8500 RPMs, but I can only go to 7500 RPMs. Does anybody know why I cant go to 8500 RPMs? Is there a safety feature built into the ECU or do I need to upgrade my valvetrain? Also if it adjusts my timing, should I put my timing back to stock? And can I still put it to stock with a chip installed? Any info would be great, and let me know what chips worked for ya’ll. ---
