Not sure what you mean by being scientific but, I'm trying to calculate the fuel flow and compare it to the MAF rate. If understand how the PE fueling mode works, it uses the MAF rate and the EQ...

Is this right?

From scanner:
IFR = 43.81 lb/h
InjDC(%) = 77.0 %

fuel flow per cylinder = IFR x InjDC = 33.73 lb/h
total fuel flow = 4 cylinders x flow per cylinder = 134.93 lb/h

Your...

Here's what my primary table looks like now

I used the Beta version of the VCM editior to read my ECM and TCM. Afterwards I opened the 2.24 scanner to log some data and now all my sensors and PID in the Primary Table are screwed up. When I try...

thende or JimmyS:

Does your Auto Shift Properties - Shift Pressure tab look like this?

I was going to select Performance for my Shift Pattern Type - Pattern A, but it doesn't show up...

Here' something different. My transmission is set up with shift pattern types: Pattern A - Normal and Pattern B - Cruise. Additionally, when I'm in L my transmission only uses 1st and 2nd gears.

I...

This one?

Please correct the IAT Sensor range values in the VCM editor for an E38 (E37) ECM (see below picture).

Your speedy response will be appreciated.

I looks like a typo was made when the range values were entered (see below pic)!

Should be an easy fix......

Thanks for your speedy response

If it's +/- couple of tenths a wouldn't worry about it.



Yep, write your custom PID, test it, them move on to the next step.



Your welcome. After you master this part of your tune you'll...

Please fix the VCM editor to allow me to change the resistance values in the IAT Sensor Curve table. Presently, when I change any value in this table the displayed value changes to this 493.

I looked at the instructions to the AEM UEGO 30-4100. It has a table of the sensor calibrations based on the fuel. For gasoline your sensor calibration curve looks like this:

You'll need...

Your algorithm is correct: 100 x (Actual AFR - commanded AFR)/commanded AFR.

Here's what I'm using. ([PID.7101]*2.75)+7.65)-[PID.6001])/[PID.6001]

Your first term in the expression will be...

I've got 2.24.649 loaded. Is there a page that will tell me what the latest version is?

Thanks, Bill

Has anyone else noticed this anomaly? My WOT status bit is on all the time! The Closed Loop status bit is off most of the time except on occasion it turns on after the PE switches to off! I think the...

I've created a histogram using the Command EQ Ratio (SAE), but it looks like I don't enter PE mode until I'm above 3000 RPM.

I'm trying to initiate the PE mode at 39% TPS,...

Thanks for the help. I down loaded the new tune and drove the car around last night. I thought it ran pretty good on the kit tune, but now its so much more responsive. It idles better now too. I...

I got that done. I also copied the High Octane map to the Low Octane map. Now its time to download!

If got everything else entered except this. It's taking awhile to get these changed. I'm going to have to finish this in the morning.

Thanks again CSSOB!

I don't have a clue why he tuned it that way. The guy that tuned it has got street cred with the Solstice and Sky owners, but I've not got any help tuning his kit. Anyhow, this is where I'm at...

Thanks for your help!
:yay:
I have a couple of quick questions.

1. Does the LE5 use the same ECM as the LSJ? When I cross reference the ECM part number it comes up as an E38, but the VCM Editor...

Can someone look at the attached files and let me know if there's anything I should be concerned about?

I'm new to this calibrating stuff. I bought a supercharger kit for my 2008 Saturn Sky with...

On the VCM Editor window Engine Diagnostics/Airflow it shows a IAT 2 table. Is this a sensor input? If so is there an E38 pin # associated with it?
