Wide and narrowbands both look similar also they are both four wire.
yeah i don't know why they would put a wb on the cobalt and go back to a nb on the cruze, so maybe it is wb, i sure hope it is.
chris, is there anything indicative in the tune?
If I were to take an educated guess I would say its a narrowband.
They only switched to a wideband on Cobalt SS/TC which used a bosch pcm
With ac delco pcm's such as E37, E38, P12, etc they've always used narrowbands. The cobalt having a wideband was likely a phase, not the norm.
It doesn't have to be perfect, it just needs to be done in two weeks...

looks like NB to me

Trying to read my 2012 Cruze... this keeps coming up, is there another version of beta i need? using this currently: VCM Suite Product: VCM Editor 2.23.569 Beta
Security codes denied Unknown error: 11

Yes, you will need latest Beta if it will read .
Yeah download the newest beta 2.23.627, also keep in mind this software is only for 1.4 cruze

Ok emailing support for an update, its a 1.4T Cruze ECO 6 speed manual.Yeah download the newest beta 2.23.627, also keep in mind this software is only for 1.4 cruze

Hmm still doing this error after the beta update...

Email support with an infolog & screenshot of the error please.

After 3 straight attempts in a row it took! I was able to download the tune. I emailed it to support with an info log so it can be made useable by me, thanks!

FYI, Cant upload due to the drop down box limitations not having the cruze or sonic listed, nor the 1.4l engine option in that boxIf you want you guys can start uploading these, sonic 1.4t, 2012 Camaro V6, etc reads to the repository http://www.hptuners.com/customers/tune_upload.php I'm sure we'll have other guys wanting to see what these new pcm's look like from an internal standpoint. For our customers privacy we(HP Tuners) don't upload any tunes to the repository so its purely voluntary

Whats the difference between the Throttle Positions?
one is normalized to the max open position, the other is the raw sensor % 0-5V

Well, more specifically,
When ETC Position is 100%
what is ETC Pedal Position? - at 36%
Throttle Position (SAE) and Absolute TPS (SAE) match at only 84%
What are Accelerator Position 1 and 2 at 42% and 20%?
How do these relate to each other?
ETC Position is what the driver is commanding?
Absolute TPS is what the throttle blade is opening?
What are they??
Ok the above figures were at 1900 RPMs.
As the RPMs go up ETC Pedal Position gets to 99% but the others are still 84%. Accelerator Positions increase also but not very much.

ETC position is the measured position of the throttle, normalized to the fully open position (which is not the same as 5v) on the TPS sensor. ie. it will be 100% when TPS might be around 80-90%.
Pedal position is the position of the pedal.
There is another PID called "ETC Desired Position" which is the desired position.
Absolute TPS is the 2nd TPS sensor absolute value (ie. 0-5V in %). ie. the same as Throttle Position (SAE) but for sensor #2. I've renamed this to Absolute TPS B (SAE) in the next beta.
Usually the sensors are set to read inverse to each other.
Sometimes the SAE PID names are not clear becuase SAE started out with only a dozen or so PIDs and now has many varied names and PIDs and some that manufacturers implement as the same thing etc.
Additionally, sometimes GM screws up the scalers for some of the PIDs and i need to revisit them.

Alrighty, thanks for the explanations!
Am I understanding you correctly that the throttle blade can be 100% open even though the Pedal Position is not 100%? It seems in my log the ETC Pedal Position lagged behind the ETC position.
Or is ETC Position the wrong metric to use entirely when trying to judge the openness of the throttle blade? We should be using Absolute instead?

pedal position is the position of the gas pedal, the Driver Demand tables (Engine, Torque Management, Engine) map the pedal to a desired power which goes in one end of the torque sausage machine and out the other end comes desired throttle position and a bunch of other things.
The best throttle PIDs to log are:
- ETC Desired Position (the position the ECM is trying to set the throttle)
- ETC Position (the measured position of the throttle)
- ETC Source (the system that is currently controlling the throttle)
- Pedal Mode (which map the Driver Demand is using)
- ETC Pedal Position (the pedal position, so you can see when you hit the gas)
- Driver Pedal Axle TqReq (the torque request from the driver)
You can also log the various predicted (airflow controlling) torques and the immediate (spark and fuel cut controlling) torques, desired boost etc.

Where does one find the new beta software? Should it be on the "current build" menu in my profile? Mine is dated Apr 30th, 2008...or is that just never updated?
