looking for a Jeep stroker expert in Los Angeles

“However witht he stock ECU timing can't really be adjusted”

-This is wrong, the stock ECU timing can be adjusted, with a DRB2/3 you can retard the timing, and the ecu can be chipped to advance the timing. That being said, I cannot see how the normal advance mapping could cause a overheating issue.

“yes, we have cut off the tooth in the distributer and tried to turn it to get better timing but the ecu keeps changing timing to 12 degrees not matter what”

-You cut the tooth ??? What does this mean, and how do you expect to change the timing doing that ?

-How are you coming to the conclusion that the “timing is 12 degrees not matter what” ? Are you reading the timing at idle, off idle, under load ? Do you understand that timing varies considerably based on rpm and load, and that it is typically lowest at idle?

As jsawduste pointed out, these Jeeps have good cooling systems stock, in Los Angeles, you should not have overheating issues, as long as everything is working right.

I believe you would save yourself a lot of trouble, if you were to bring your Jeep to a competent /experienced mechanic or individual to properly diagnose this issue.
