Thanks!

How do you change the VIN in V8? I'm using FlashScan V2.

Thanks guys. I now understand I cannot use V8 to change the VIN. I was able to change the VIN with V7, but the PCM Security option was greyed out at the time I posted the question. After messing...

Hi Guys,

I'm scratching my head with the VIN change process for a 2007 E67 Trailblazer SS ECM.

I'm unable to choose the VIN change option in V7 software.

In the V8 software, I'm able to read...

Here's a picture of our new SBC timing cover installed. Machined 6061 aluminum. Anodized black. Face milled for additional logo detail.

For much of this year EFI Connection has been working on a new crank/cam signal conversion for both SBC and LT1 engines. We set out to accomplish two things...

Eliminate crank signal issues where...

That's beyond my control. You'll have to make that recommendation to the publisher.

Who is Airdeano? How has Airdeano used the 411 PCM? I know there are many guys who have shown strong interest in this PCM through the years.

Here's a stroll through memory lane. I posted a thread...

There's a new book available to help plan a Gen III LS-Series PCM conversion. I worked with CarTech to make this information available.

Mallory makes one.

Not in a 6 cylinder configuration. There is no supporting GM calibration. We will use the Holley...

Here's a sneak peek at what we've been working on for 1987-up SBC and 4.3L V6 engines. Early SBC engines won't accept the timing set, but depeding on demand, we may support the early SBC in this...

Keep in mind that the 2002 4.3L S-10 uses the 12200411 PCM and a flat response knock sensor. Because this is true, it must be that all 12200411 PCMs have the hardware for the flat response type knock...

System segment swap.

That's not what I'm saying. I don't recall, using the resistor, if the A/C Pressure PID displayed a value when using the truck calibraiton (I don't see why it wouldn't).

I did a lot of bench testing on this about a month ago...
- 12200411 PCM
- 24x signal generator
- 0-5V A/C pressure sensor
- 12V LEDs as indicators for fan 1, fan 2, and A/C relay control
-...

No, nothing. The harness, ECM, and TCM have been delivered and will soon be installed. My customer requested to proceed with the TCM. If he runs into any problems related to VSS or TCM without...

I do. Not sure if I'll have a chance to bench test that this week.

I'm curious about this as well, but don't have an instrument cluster on the bench to know.

I'm using a VSS from a T56 transmission and spinning a reluctor on the bench top. The 158 mph value is odd because it is displayed with VSS connected and without TCM connected. Once the TCM is...

Thanks Taz.

I can also tell you that without the TCM, SAE.VSS always displays 158 mph. I disabled U0101 (Lost Communication With TCM) with no effect on VSS.

Thanks Alan.

Are these EFILive parameters or HP Tuners. I cannot find these in the EFILive E67 ECM calibration.

*EDIT* I don't see these in HP Tuners either. Maybe this is specific to the GMPP...

I agree! The only catch is that the project requirements include cruise control...which locks me into the Trailblazer SS E67 ECM.

I added the TCM to the bench and the VSS works fine. I'd like to avoid the TCM if at all possible.

I'm working with a 2008 Trailblazer SS E67 and want to use ECM C3 pin 66 and C3 pin 67 for VSS high and VSS low because of a manual transmission application. While this looks good on paper, I'm not...

You are using a PCM calibration from a vehicle with a PRNDL switch on the side of the transmission.
You have wired in a P/N switch (which will supply a ground to the PCM when in park/neutral,...
