Hey Guys,
I got a call to work on a car last week, I updated HPT to 3.0 that morning and then went to the job.
I'm working on a 1952 Chevy limousine that has had a 2004 LQ9 & 4L80E swap. It's...
I noticed that the drivers were already good to go, it was nice
same problem, what did you do? I just went from a laptop with vista & 2.24 to a tablet windows 8 & 2.24, I test scanned my 09 gmc 1500 previously tuned with hpt and got the exact error.
EDIT: I...
I would simply just turn off all Transmission related DTC's, as well as zero out all torque management tables. I would start there and see how she reacts.
I have had the opposite on my own truck....
I'll try the battery disconnect today.
Hello,
I have in my shop a 2005 Cadillac CTSV that apparently has a bricked/dead PCM after a HPTuners flash. The PCM initially scanned, the cal was modified and flashed to the vehicle. Upon the...
Essentially what your feeling is as if you reduced static compression of your engine. While in higher elevation you can run more ignition timing without knock, but it may not compensate for how much...
Use the correct PCM for the truck model, problem solved.
Chuck, my advice to you or anyone that is in the automotive modification business receiving heat from online forums. The natural human response is to reply to online internet banter and speculation....
After seeing your log, my first reaction without even looking at the tune is dial in your LTFT's. Spend some time tuning VE than MAF using the How To's on this forum. Once you have the fuel trims as...
Please don't take my advice to be the answer all/end all in your tune. Experiment around and you may find your truck likes more or less timing in certain ranges
Unlike the performance and racing...
I reviewed the tune and log and have some pointers, I'll respond when i'm not on my iphone
If you could, do another log with your current tune while the truck is hesitating.
At this point I would spend more time tuning VE and MAF tables. Refer to the write up's here on HPT forum for the...
No tune, no log... no help. Not much we can do to help without your tune and a log
That's what I thought too, that's why I don't modify these tables at all. I wish there was a little more info on this TAC boundry vs Fried PCMs
Under engine>torque management > General> Max Torque to 640. and the rest of the tables under it to something like 40,000,000
Max torque vs rpm, all to 640
ETC Limits, ETC TPS Max, too 100%...
Give the guys some time respond, this board is slow sometimes. I'll look at the tune and log later when not on my iphone
^^ This
Not to mention there are a few, rare, tables in the PCM's we don't even have command over in HPTuners and settings from one vehicles tune might not jive with these unchangeable settings in...
I dunno about the respiratoary (??) but the repository might
As mentioned before, remove throttle spacer. They just disrupt smooth airflow into the intake manifold. And put the screen back on the MAF, it's designed to have straight airflow go over the sensor...
I am slowly thinking of a 6.0 build....when I win the lottery.
I do like the demon carbs, I just found the secret to getting them to run right was in the ignition timing and initial/idle timing....
I do still have the SBC in my truck and it is carbed. I just had to rebuild it's third trans. Now it has a manual shift 4L65 spec with vacuum modulated shift pressure. It's been a learning experience...
Because theoretically an engine is as close to stoich as possible while not in PE so 14.7/1.165= 12.6:1 AFR. Anywhere between 12.3-13AFR makes best power.
This is why dialing in fuel trims is...
I don't understand the problem
Good run, looks like a modest tune. I was a little caught off guard by 27 degrees idle timing an than saw that was stock.
Hell, I use 27 degrees idle/initial timing in my 11:1 compression 357 with...
