  1. Run a compression check on the motor. Then post the results. Check your oil level.
  2. Any ideas on where to purchase "New" AW4 solenoids. I have Googled and I keep seeing the solenoids for 87/2001 for Cherokee's, 90-93 for Comanche's. I know no 93' Comanches thier info not mine. Any body found a reliable USA based manufacturer of these components. I want to do all three.
  3. The LTFT numbers I guess indicate less fuel required to hit the stoic magic number of 128. Pulse width closed loop after warm up and at idle is about 5. to 5.1 ms
  4. Appears that the O2 is functional STFT moves from 117 to 134, LTFT up to 101 as of this morning. Thats as high as its gotten since the last new O2 install.

Renix ECUs do have a KAM Keep Alive Memory which does store a few values such as previous LTFT, TPS closed %, and how many key cycles since a sensor fault, though I'm still trying to find that last one. The big debate is if Renix stores trouble codes which it does not save for the key cycle. I'm going to do a lot more looking into the few mystery values still left in the stream to see what I can find eventually. As for LTFT in general, after a reset it will read 128 which means it is using the stock look-up table. Once the vehicle sucesfully stays in closed loop then it will start adjusting STFT and an average deviation will be found which is the LTFT. So LTFT shows you the average correction factor from the stock tables that is needed to stay stoic. STFT is the current needed deviation I think, and I forget if that changes in open loop. Lower LTFT readings means it is using less fuel to stay stoic, and higher readings show more fuel is required. For my stroker it sits are 176 but will go a little lower if only city driving. This is the guy who's manufacturing the in-cab diagnostic readers, he a lot smarter than me. But he knows the insides of the Renix computer and a lot of its construction.
  6. 746's are flowing @ 20.2 lbs/hr and 212 cc/min. Stock injectors are flowing @ 21.5 lbs/hr and 240cc/min. These are or should be based on 43.5psi fuel pressure or 3 bar. Could the ECU be trying to compensate for flow from the 746's. What funny is the calculator says both stock and 746's are providing more fuel than required.
  7. This cam out of the Snap-On MT2500 Jeep Guide
  8. The AW 4 the Dana 44 with Trac Loc, and 4.11 thick gears, make driving, the Eliminator easy/peasy, I'm spoiled, not a lot of freeways on the island, but we do have some challenges with lava roads and pretty severe grades. Climbs like a Billy goat.
  9. The O2 is the third one in 10 days, had initially ??? O2, put in the NTK, lasted 2 days, then another NTK, 4,5 days, now the Bosch a couple of days, so far so good
  10. Get rid of that BA10, you should be able to find an AX15. What gears? 3.54 or 3.07?
  11. I have the 89 ECU, 746's, and a 60mm TB. Stock airbox, stock sensors, now running the Bosch O2. Stock plugs, coppers.
  12. JMO413, & OHM are you both saying your LTFT is 90, 91 and now mine is 91 what are the chances of that being random versus something that was designed into the fuel mapping?
  13. Ok just got back average speed 45 mph, for about 30 minutes. LTFT is now 91 down from 97
