HACKMAC87 2 Report post Posted November 15 The jeep I6 4.0l engine has an odd trigger wheel. It is 3 teeth then 2 solid then repeating 3 times on the flywheel. Is there anyway to set this pattern up in the ecu? Quote Share this post Link to post Share on other sites
Adamw 586 Report post Posted November 15 Use the "Jeep Cherokee 2000" mode. I think from memory it is 18-2-2-2 on the flywheel which sounds like what you are describing. You will need to be on the latest firmware if you dont see this mode in your ECU, it was only just recently added. Quote Share this post Link to post Share on other sites
