I'm fairly new to tuning & am wanting to remove TM (if it has any that affects it) from my 03 RCSB with a 4.8, 5 speed Silverado 4x4. I've also tried following the VE tuning tutorial on here with no luck. When I try to put the truck in SD, it won't run. It'll start but die immediately, even if I try to give it throttle. Can anyone help me out. I'm using HP Tuners standard also

 

From what I have seen the normal TM (not any of the other torque limiting parameters) is mainly used on automatic when shifting. It pulls timing or throttle when shifting just for a split second. You won't see it used so much with the manuals, but the thottle parameters limit the power.

Yours is DBW correct? I have seen a good calibration floating around for a 4.8L manual trans with DBW. Can you post you tune?

Oh just for tuning in SD max out your P1514 table and see if it will not stall out

 

I will try posting my stock tune in a little bit

 

Here is my stock tune.

Change this table to allow you to run it in SD
Allow the MAF to set DTC's


Change these 2 tables to match this




I run this table slightly higher than this. This is only 1 of a set of tables that need to be in a range of each other (Redundancy). Not having a bin file I am guessing that this will be safe. If it is not safe it will brick the PCM. Like I said I have found that this table can be much more aggressive. This is mild


Changing the TAC tables with give you more throttle response. All of the TAC tables that I posted are OE in a 2003 calibration, just not a Manual Trans

 

Anybody else have any suggestions. I haven't tried any of the changes that have been posted yet. I'd really rather not turn my PCM into a brick messing with the TAC tables. I would like some better throttle response out of the truck.

 

target idle speed is 0 for P/N

 

just realized you had a 5speed, what all are you turning off for SD

 

The 3 tables that I posted are 100% safe to do

The top table needs to be done to drive it with the MAF unplugged.

 

I'm going to change those tables then. Now when I change the top table that you posted, does the MAF need to be unplugged? I know that the IAT sensor is also part of the MAF
