99 cherokee 4.0 crazy knock retard

[jrogers0696]

so im stumped at this point, i have no idea why im getting this knock retard and ive done everything to try and stop it, all spark ive even turned off anything to do with spark retard or spark knock, it can sit key on engine off and itll bounce from 7.5 to like 120 of KR ENGNE NOT RUNNING... while running it does it to and it bounces the injectors with it. and ontop of all that these jeeps dont have knock sensors. heres a log of it doing it, and the the stock tune it was on (this happened before i ever touched anything in the tune)

I didnt even know them ol 4.0 i6's had knock sensors. My 04 4.7 WJ has them but only because its an H.O., the regular 4.7 and the 4.0 dont have knock sensors in the WJ. Post up your tune file and logs.

Ya, I?ve never figured it out, it drives fine, and I actually just built and dropped in a 4.5 stroker over the weekend, only test fired it so far. But taking it to windrock like next week. Cherokees do have a 4.0 HO, but no knock sensors? So I?m stumped as to why my scanner bounces KR and injectors like tha
