mopar pt?????

[derekf]

Are there more sensors that just those four, or is there some sort of external programming interface? I can't see it being tuneable without being able to configure injector flow/engine CI/etc, or at least some oxygen sensors so it can monitor itself.

hell yeah! another mopar man... my car is little by little making it to Pro touring... building a 528" EFI wedge currently... will be getting tubbed and caged next summer

i know it seems weird ,there is no oxygen sensor or external hookup
heres a clip from the manual

9.0 USING THE ECM

The ecm is very simple and easy to operate. It can learn most functions needed to run an engine on its own, however there are several features and adjustments that need to be explained.

9.1-9.9 Priming, idle system, etc.

10.0 GENERAL TUNING INFORMATION

The ecm tunes by seeking out the peak torque an engine can produce at a given load. After every new point is tuned the ecm uses this new point as well as all the other previously tuned points to build a fuel map optimized for the engine.

The ecm is used on a variety of engine sizes and power ratings. Until the ecm has learned about your engine it may cause the engine to run rich. It may take several minutes to tun these first points correctly. As the ecm gathers more information about the engine and has built a more accurate fuel map, the final points the ecm tunes will take less time than the first points.

The ecm is tuning correctly when the Check Engine light is solidly on and the engine is either increasing in RPM or running at a constant RPM. Because the ecm has to wait for engine performance data to analyze and tune the engine, the lower the RPM the longer the ecm takes to tune. At 900 RPM the ecm can take up to 10 minutes to tune a point. At 3000 RPM, the ecm can tune a point in less than a minute.

When the ecm encounters an un-tuned point it will immediately start to tune. If during the first 8 hours of operation the vehicle stays at a load point for more than one minute the ecm will re-tune this point. After 8 hours the ecm will re-tune load points whenever the engine stays at a given load point for more than five minutes.

For the ecm to build an accurate fuel map it is very important that the ecm be allowed to tune every point it can. To optimize the tuning process, the engine needs to be kept under constant load until the ecm has finished tuning.

like i said it ran good at first but is getting worse
