Hey guys, bought another cherokee a 92 laredo with 4 inch lift and wanna use it but the ecu smokes so no driving lol What ECU's will work on it? And do i have to program it or can i just take one and put it in and drive. Id rather do a junkyard than new so any help about ECU's id appreciate it!! Will any cherokee from 91-95 work? thanks!

 

91-95 will work without flashing. but, i would erase the adaptive memory anyways

This very simple procedure will Erase the “Adaptive Memory” stored inside the PCM and allow a new “Adaptive Memory” to be developed.

After performing this procedure the PCM will re-learn and store into Adaptive Memory your engines performance characteristics.

Please perform these steps exactly as they are written, in the order they are written. This will cause the adaptive memory in the PCM to be erased and cause the PCM to go into Fast Learn Mode adaptive mode.

Disconnect the battery terminals and touch them together for 30 seconds. (This is to discharge the PCM capacitors, which maintain the Adaptive Memory.)
Reconnect the Battery Cables
Turn Ignition Switch to the “On” position but DO NOT start the engine
Turn Headlight “On”
Turn Headlights “Off”
Turn Ignition Key “Off”

The PCM Adaptive memory has now been flashed, or erased from the PCM.

When you start the engine it will be running off a set of pre-programmed tables that come with the PCM from the factory.

When you get the engine up to operating temperature the PCM will start to collect data for the “Adaptive Memory”.

The PCM will collect data for Adaptive Memory for the first 50 Warm-up Cycles.

 

Check your battery voltage with the engine running before you pop a new one in there, make sure it isn't what blew the PCM. Just in case...

 

I had a Question also would it matter if it was a Standard or auto trans as i am having the same issue. Mine is a 5 speed n a buddy of mine has a ECU from a auto.
Thanks,
