I can easily fix that in Open Loop F/A vs. Coolant temp.

I'm not sure why I had made them 1.0 in colder temps. I'm assuming I should begin data logging after 160F once the AFR goes into stoich.

So I've been trying to get my startup, idle, and daily driving tune going.

I did the necessary things to do a MAF tune, however I think I'm missing something.

So when I'm tuning the MAF I do...

First off everything is working as it should, 1st fan comes on when the a/c is enabled via the PCM, if the engine gets too hot it will turn on the 2nd fan and the 2nd fan shut off at the temp that I...

Alright, looks like it was my fault with the wiring.

Come to find out i had swapped the 5v & cam signal wires. fired right up after fixing my mistake.

On I side note, i would not recommend...

yes, Both to the ECM and TCM (I don't think the TCM matters) I'm not sure if I accidentally disabled something with the cam (which I doubt, but i can be wrong) I attached my tune to the first post.

It has a 4x Cam sprocket on it.

I would attach a photo but the forum isn't letting me.

I've been working on project swap, the engine I'm working on is a 2008 6.2L engine with a E38 ECM.

The engine originally had AFM and VVT. BOTH have been deleted from the engine.

Using HPT I...

another thing, i'm assuming that it?s best to do the idle tune first before moving into tuning the VE?

Alright, so now i have an idea of what to do. I'm gonna let the car cool down overnight and start in the morning but I since I'm running the newer version of HPT, the old idle-airflow.cfg didn't open...

I just found out about using a wideband o2 with the pcm via egr or a/c pressure pins, it prolly wont be till next week when I can get a bosch wideband o2 and then wire it up. just an fyi I only have...

I got everything setup on my scanner to record iac counts, ltst trims and mass air flow, but I do have the maf disabled for me to ve tune. If i enable it the engine goes to crap since the maf isn't...

So I'm running into some new issues.

Recently I installed a FAST LSxrt intake on my 6.0L LQ4, I made the proper fuel injector adjustments into HP Tuner and the engine started right up but I'm...

Well after much tinkering and the loss of 2 GM credits (more on that) I finally got it to work.

First off, I have two Truck PCM's the first one is the one I've been using, its the 2001 Truck PCM...

I figured as much that it looks like I'll have to go into a f-body system, I do have a spare 411 PCM that I'll use to load up a stock f-body system in it. I'll have to change out just a few pins from...

To be fair, you only have provided a more of a manual way of enabling the fans when the A/C needs it (via Pressure switch on a/c line that switches the fans on/off)

I've been reading 'How to Use...

You are correct, however I'm not sure by what you mean by segment swap. Be easy on me, I've only had HPT for about 3 weeks now, lol.

Unfortunately, changing the fan Parameters only affects it with Engine Coolant temperatures, from all the documentation I've been reading up the Truck system has no control for fans when the a/c is...

Sorry for the new post, but since this is a little different from my A/C Fan post, I figured I make a new one.

I need some guidance right now as I'm still new and learning each day..

Doing...

Alright, after thorough researching over the past few days I have come to the conclusion that using the Truck calibration simply just won't work for a/c fan operation. At all.

From much reading,...

Here's the problem or maybe misunderstanding, by Default/Factory settings 01-02 PCM didn't have any options for electric fan control as all trucks up till 2003 had mechanical fans.

With HPT, it...

So my next question would be, is it possible to update my PCM to a 2003 so that way i have some control over the fans during A/C operation?

Granted I do not have the original PCM High/Low pressure...

Greetings,

For several days I've been trying to troubleshoot on how come both my fans for my 2001 411 PCM w/ OS 12208322 in a 94 Buick Roadmaster wont work.

I do have the settings and the...

I guess I should have researched this a bit more.

Currently I have a 6.0L with a 01 Silverado PCM with OS 12208322 in my 94 Buick Roadmaster and for days I've been trying to find out why when the...

First off, I'm new here so take it easy on me. lol

Lemme give a little bit of whats going on and what my setup is.

I have a 2004 6.0L (bored .030 over) LQ4 with LS2 intake and injectors...
