Please post the tune, not the log. Are you tuning this truck with HPT?

 

HPt im really not sure how to post a tune can some please tell me how to post the tune?

 

Save your tune to a file in HPT, ZIP it, then upload it here using the upload manager in the post menu.

 

Then just browse for your tune file and select it

 

Alright guys I've been doing some research and from what I read to help with Torque Converter lockup was to change TCC duty cycle? I changed the Minimum to 98 and Maximum to 100 and I did that across the whole table on both.

This did absolutely nothing it keeps locking and unlocking constantly!


My Mods are 6.0 bored .030 over
Comp Hyd Roller 54-4 12-11 Cam grind
XR265HR, 1200-6000, 265/271, 212/218, 512/529, 114 lobe sep Angle
comp lifters
Circle D 3000 stall converter
#60 injectors
72mm turbo

 

I wonder why no one will help you.. This thread is pointless

 

Are your misfire tables in your tune still on the stock factory settings? If so that could very well be causing your issue, even with a mild aftermarket cam such as yours the PCM sees false misfires due to the cam. Misfires will keep the converter from locking up and or staying locked up. Raise the values in the misfire tables and see what you get.

 

If he can't figure out how to post his truck's tune and a tuner hasn't messed with it I'd venture to guess their stock.

But really OP. Go on the HPT forum, read the sticky on how to use HPT to tune, and learn how to read the tune from your truck. Save it to your laptop, then upload that file just like you did the logging file.

Then you might get some meaningful help.

Once you post the tune file I can give you some pointers on TCC apply/release strategies I learned from researching on how to tune transmission settings from EFI Live's forum guru JoeCar and others. PS, there is a nice tuning FAQ/DIY guide showing what you need to do over there that you could use (you would just need to figure out what the HPT tables are labeled and cross reference those to understand EFI Live : HPT.

 

Long story short I paid Nelson performance to tune it when it had the 5.3 and turbo but not the stall converter. I got to drive it about 300 miles and the thrust bearing went out. I went looking for a replacement and came across the 6.0. I talked Allen from Nelson performance and offered to pay him but he was very nice and sent me another tune for FREE.. The only problem is I forget to metion the stall converter and his already been nice enough so figured I could atleast try and tune for the converter.


I've looked through the HP tuners and I can't seemed to find anything that helps to tune for the torque converter.

I read several places about a book that breaks all of it down but can't seem to find the name ?

 

The way I see it you have three choices.

1) Post your tune, so we can help you solve the problem.

2) Ask/pay? Nelson to correct the tune for you.

3) Figure it out on your own.
