When chipping an OBD1 Ecu, it says to jump J1, (connect it) What should I use to do that? Thanks.

 

one of the cutoff legs from one of the resistors/caps

 

yeah just a spare piece of leg from a resistor etc. will di just fine. makes for an easy snip if you need to switch back to stock too

 

an obd0 ecu there is no need for this correct? I read the writeup at ecucontrol.com and think you just unsolder the old chip and solder in a socket right? im about to chip my ecu and need some clarification. (sorry if im a highjacker)

OBD0 ECUs capable of having external EEPROM sockets on the native PCB are already setup to do so.

So, yes, just unsolder the chip, and solder in the socket. "J1" is already shorted.
