Wanting to tune our 2007 Jeep Cherokee Laredo 4.7L for better gas mileage. VCM Scanner connect to computer via OBDII port but does not pull up any supported parameters. Tried adding them through...
Installed 2.22 without un-installing beta version. 2.22 could not load any of the configs or settings from the beta version files. Re-set up most of my config settings. Scanned 15 minutes without...
Will do tonight.
Using the Beta version of HPT and at least once in my scan, the ECC blanks out and the A/C kicks on. The ECC panel is completely locked out, usually with three dashes ( - - - ). Can't turn a/c off or...
Yes.
From my CSV file, O2 Voltage B1S2 (SAE) mV ranges from 45 to 685mv. WOT voltage continues to fluctuate up and down, whereas the narrow band will plateau around the 930 to 950 range. ...
Here's the formula you posted on P3 setting:
(([PID.21]/425)*8.5)+10

I'll switch the gauge to P4 and post those soon...
Interesting...according to AEM user guide (link above) it says, "The AFR calibration (P3) emulates the Autronic Wideband O2 Sensor calibration (0-1V)." But the graph shows P3 doesn't go above...
Not quite.... here's where I'm at. I switched to the PO3 setting on the AEM. I'm working with a guru on another forum. I was hoping the experts here would chime in, but haven't seen any posts...

You have to add a user defined PID. Go to your primary table, right click, insert, under "user defined" choose Configure User Defined, choose a table (I think one has WB as a default).
Here's a...
It says the output voltage can be changed from 0-5v down to 0-1v however, going through the O2B2 sensor, I haven't found the right formula yet. I have not thrown a volt meter on the output to verify...
Found it! The AEM version I have has switchable analog output voltage!
Configuring Calibration Outputs
If a different O2 sensor calibration is desired, the AEM calibration can be changed to one...
I was thinking about it... if the voltage supplied by the WB is 0-5v, and the rear O2 is measured in mv (or 0-1v), the conversion would be PID.21*.001 to get the votage in a range of 0-10v, then the...
Here's a scan with the NB analog output connected to #2.
I can't view the custom PID formula w/o connecting to PCM (standard).
Not sure at all. I've got the WB installed and working on the gauge in the Pod. The AEM has a serial output and an analog output wire. I connected the AEM analog output (White) to the OEM signal...
I've wired up the AEM analog output (White) to the OEM signal wire (purple) using the existing down stream harness not being used.
Looking for proper custom PID formula that converts O2 B1S2 mv...
Or if you're not using the sensor after the cat, I think you can wire right up to the existing harness.
I was told it's the Pass Key II resistor that commonly breaks in the steering column. Fortunately for me, car still starts and works fine. I don't feel like pulling the air bag to find out.

Was going to write BIN w/ PWM enabled, when I noticed in my last file that it already is set to PWM :confused: Sooo...in v2.23, if you change PWM to Serial it's the same as if you changed serial to...
Downloaded beta version, changed VATS from PWM to Serial and wrote calibration only. Recall DTCs were already disabled. I started the car and it stalled after 3 seconds run time. I did not have...
I downloaded the file from this page and opened it. In version 2.22, VATS is set to PWM.

Scan today w/ VATS status bits included.
Wrote new file to PCM with PWM VATS and would not stay running. Here's the bin and scan. I could not find the PID for VATS. I emailed to you Bill and [email protected] (is that right?).
...
Agreed. I too want help on this.
:D Sweet! I have AEM WB that is going in soon. Thanks!
Same here on my 99. All DTCs regarding VATS is disabled and no reporting. Won't run on PWM VATS. Only Serial
