Thanks for info!!

Thank you very much!
No, I dont`t have WB, so I will use LTFT+STFT.

Hello again!
Now I`m trying to dial in the MAF sensor on my LS 5,3/4L60E setup.
At least I think I`m pretty close with the VE tuning, so yesterday I started with the MAF tuning.
I found this on...

Update!
Today I have tested the car with the segment-swapped tuner file. It was a complete different car to drive, so much smoother shifts and no more sudden downshifts!!
Thank you so much for...

Thanks a lot for information!!
I've just done a segment swap on the transmission. I did find a 2003 Tahoe witch 5,3/4L60e in the tuner repository.
I guess I don't have to do segment swap with the...

That's right, the pcm came from a truck so I just changed the different tables.

I`ve done some changes;
Here is screendumps of the DTC`s:
Suppose it is correct with the P0101, P0102, and P0103...?
I`ve also included P1514...
The dump of the scanner shows the channel list to...

OK, thanks!
If you think this strange downshift issue is related to incorrect setup, I will for sure try out what you suggest and cross my fingers It will solve my problem...!
This is my frist...

Hi!
I need some advice to solve my downshift problem.
I`ve recently swapped a 5,3/4L60e from a 2003 Tahoe into a classic car.
Runs and shifts fine from the start, but after running about 2-3...

Could someone please help me to look at the enclosed files?
I`m struggling to get the shift points correct. It shifts up way too fast, it`s in 3-gear very quick with very low rpm and speed. I`v...

Ok, thanks for quick reply!
Soory, but as a newbie I have to ask; Could I download a tuner file from a car with LS1 intake and copy over these tables to mine?

Hello!
I`ve just fired up my 5.3 L Tahoe engine in a 65 Chevy, and in terms of tune it properly I do need some advice.
First of all it is a 2003 L59 Flex fuel, with a LS1 intake from a 99 Camaro....

I sure will lower the settings!
Thank you both for all help, I really appreciate!

Then I have to assemble the harness in the car and give it a try. Hopefully it`s ok as long as it works with the bidirectional controls.

Ok, but this bench test would then be a simulation of an engine that just have been running, as long as the temp sensor reaches the preset value............?
Maybe I should try to turn the ignition...

Yes I can.

Yes, the temp goes up over 120 degree Celcius.
I monitor it all the way from 20 deg. to 120 deg. ++, but no engagement at pin 42 and 33............
I`ve also tried lower values of start/stop. Still...

I carefully put a soldering iron close to the sensortip and monitor the value in VCM scanner. I`ve done this on several applications without problems.

Hi, and tanks for quick reply!!
Enclosed is my tune. Actually it is a copy of a 03`Tahoe Flex-fuel tune that I`ve downloded from HP Tuners Tune Repository. That`s because the pcm that was shipped...

I cannot get it engaged..
Here is a screen shot of my setup:
58282
58283
When I use the VCM scanner control, I can turn it on manually.
Where do I set the enable speed? Can only se an option to...

Thanks alot!!
I will try it out!

Hi!
I am in a progress of swapping a 03 tahoe engine into a 65 Chevy, and am also a newbe on HP tuners

According to get the cooling fans to be controlled by the pcm I do have some questions;
