2002 and 2004 don't have same calibration file, look at fuel and PE

hi, have a look page 4, they are showing additionnal capacitors

rear O2 sensors are not supposed to switch, if they do it means cat is bad and the PCM send a code
Whats a good operating range for both stft and ltft?
-They are supposed to ba around 0% +/-5%
But when you use E85 LTFT can reach +20% for exemple in closed loop operation, then when it goes into...
There are MAP - VAC and RPM thresholds, above those threshold it goes into open loop / PE mode
The only thing you can log is your o2 sensor voltage unless you have a wide band o2 sensor
In PE...
Hi there is not so much you can do on this king of JETEC, even less if you don't have a wide band O2 sensor and nock sensor. With out wide band, you cant really tune fuel and with ou knock sensor you...
hi, I may can help you on the 5.9 spark table
me too, now my ZJ 5.9 runs on E85, cold start up to 35?F for now
or switch and tune for E85 if you are having E85 in your country
confirmed, I juste uninstall the KB5006670 then it works fine
are you facing the same problem I'm facing since few days with the 3D chart ?

I'm tuning zj 5.9 for E85
98 ZJ 5.9 and Dodge Ram 5.9 have very different calibration file, fuel & timing
Hi, it's like it can't be done because there is no VE table on JTEC, you can only use fuel trim errors in % and then apply this % error on the injectors pulse width.
