Guys, help me figure out why I can?t get my IAC counts below 134.

I have a 5.3LS throttle body on a LS6 intake on my 5.3LS engine. The engine has a mild cam, about the same as an LS6 cam and some...

Well the VSS pulses per revolution was indeed the problem. I made the change from 17 to 40, wrote the new tune and everything is perfect!
I can put the shifter in D4, gently let off the brake and...

I think I might be onto something.
Turns out the VSS in the SPEDO tab was set for a manual car, 17 pulses per rev instead of a 4L60e at 40 pulses per rev.
I haven't confirmed it yet but it sure...

Thank you very much for that. I have started doing exactly that but ran out of time last night. Its very convenient that after I copy one set of data over from one tune to the other, then I can...

Just make sure the first thing you do is READ the stock file. Save it as "2006 f150 5.4 4x4 base file" and then at any time you can WRITE it back to the PCM if things go pear shaped.

Hi Guys,

I have picked up a used 0411 PCM from an 02 Suburban for my LS swapped BMW in attempt to fix my transmission issues. This new 0411 PCM is using O.S. 12216125.

This will be to replace a...

Thanks Bill, bit of a bummer, I was hoping that was why my transmission is not acting right in my LS swap project.

Hey guys, I am getting conflicting answers to this question:

After doing a transmission segment swap in VCM Editor do I need to "Write Entire" or "Write Calibration" to the PCM?

Thanks in...

I have been working with someone I found on the Facebook tuning forum, but we are not making much headway. He is pretty busy. The tune was originally a mail order tune from LSX Power Tuning. I don't...

Hi guys,
Wondering who can help get my tune dialed in?
NA 5.3 LS in a BMW E46, with cable throttle and mild cam. LS6 intake and injectors. Engine will start and idle. Engages into Drive HARD and...

Thank you for your response. I chatted with a guy on a HP Tuners Facebook forum last night and he determined the same thing.

My original mail order tune was set up for a manual car. My new...

Hi guys, I finally bought and installed HP Tuners, and tried to create my first log file tonight, with some success.

Some back story.

I built a 5.3 LS with a mild cam, flat top pistons, LS6...

I have emailed 3 times, called twice and no response from ERM Performance. I have asked them to refund my money, but will have to file a claim through Paypal on Monday to get a refund.
I don't...

Hi guys, first post here as I am about to get into tuning my LS swap BMW E46.
I ordered the HP Tuners MPVI2 and Training Package from ERM Performance on Monday then realized I should have ordered...
