For what it is worth, here is what I ended up doing, everything on the truck is now working as expected after the P01 to P59 swap. I did not re-pin anything.


Started over with the...

I'm probably an odd ball here with the trans cluster and the GMT610 calibration... thanks for working with me!

I did previously set System > General > Platform Type from GMT610 to GMT800 but it...

I guess because I am still learning; I knew this PCM would have the IAC, TPS and AC circuits so I made an assumption this OS/cal would be better suited for my 2001 Silverado vs a newer truck that the...

Dang! I believe you are absolutely right! :cool:

I just temporarily flashed (full write) my 2004 GMC Sierra 1500 P59 (OS:12587603) into this P59 in my 2001 Silverado and bang, transmission...

Good question


The P59 PCM and OS is from a 2004 Express 3500 (Non working trans temp gauge)
The P01 PCM and OS was the stock 2001 Silverado, and later a 2002 Tahoe (working trans temp...

Hello,

I'm looking for some help and guidance on a P01 to P59 swap.

Problem: Transmission temperature gauge is not working (needle does not move from below 100*) after P01 to P59 swap.

Here is my experience with this, take it for what its worth: My early 04 would randomly high idle at 900 - 1100 RPM in any weather condition. Letting the clutch grab a bit was the only way to pull it...

I saw that I was able to get the full 120 without hitting any limiters, and I was getting the expected results so I just worked with the 120mm3. If it is advisable to only add more pulse...

Well, Guys... Here is a mild tune that I built and have been running in my truck. (Early 2004 - 305/555 - Intake and Full Exhaust)

Enhancements are only from about 2K - 3K RPM, where I felt my...

That is what I was thinking, but looking for verification.

The truck has a stock he341... only mods to the truck are intake and full exhaust... it has high mileage and has never had a...

poulioteri, Thanks. I agree with that.

My numbers are 1 - 2 degrees lower than the ones produced by the calculator you mentioned, with a 50/50 split. I am just not sure if it is good for the...

I appreciate you sharing your knowledge and theories. This is good stuff, it explains why you gave me a heads up on my timing and pw.

I believe the safety concerns here are (while I...

Thanks, BOOSTJUNKY

I really appreciate the input. So am I correct that I need to get a calculator and build my base table from that? What is the safest split for BTDC vs ATDC on the early common...

First off, thanks for contributing to the tuning community!
Can this calculator be used with the 2003 and early 2004 trucks?
Some of the values that are not configurable are different in my early...

JohnnyK05, Thanks.

That is actually what I have already done. I wasn't sure if there was more too it from an adder standpoint. When tuning GM/LS stuff I often zero some of the adder tables and...

Can you please help me understand what you mean by "Start by cleaning up the main timing tables"

I like the OP am new to diesel tuning and have recently acquired a early 2004...

Trailblazer torque converter. Powertrain wise everthing is stock except for what is listed on my sig.

Well early today I logged 'Idle Airflow - Desired Airflow' in g/sec so that I could compare it to my 'Base Running Airflow'

Anyone -zero- the throttle cracker table? or lower it a good amount? Seems this could be my problem!

I have worked idle airflow down very low as I originally did. If I lower it any more, the truck has in gear, out of gear, coming to stop transition problems. (surges/almost dies)

Anything else? It...

So I got my VE within 2-3% (using fuel trims) and worked on my timing tables. I ran in SD mode for a few days; the truck idles and transitions perfect now, however the problem still exist. I did...

Thank you for the reply. I will work on it and follow up.

Hey Guys, I hope I am just over looking something simple. I just installed my new heads, cam and headers. I have adjusted 'idle airflow' to get the truck idling. My 'P/N' is great but the 'Gear' is...

Anyone? :pray:

Any thoughts?

Hey Guys,

This is my first post on here, and first EFI vehicle I have tuned. I have been doing a lot of research and comparing of other tunes with similar mods. So please go easy on me if I am way...
