Does anyone have a custom tune that keeps the truck from surging at low throttle positions? But also gets peek hp, maybe know a web site where tunes are displayed.

 

diesel minded has a decent write up on here about them

https://www.dieselbombers.com/dodge-...-settings.html

personally i have mine set at

Timing = 7
Fuel Stretch = 1800
TPS MIN = 30 (both can and pump)
TPS MAX CAN = 100
TPS MAX Pump = 100
Boost Scaling = 25

every truck is different so a little trial bye error is involved when i first installed mine it surged but after a little playin around ive seemed to get a handle on it

good luck with the tuning

 

If your having Surge at low throttle try bumping up the TPS Min

 

After rediong my head gasket my truck runs wierd unless the ADR is on 0. It chugs TERRIBLE at 50mph when the tq converter locks. It NEVER did this before. Although i have 130hp injectors now! Could this be the cause? Also WHAT does your high idle run at? I SWORE mine used to run at 1200-1300 now its only 1000.

Any suggestions?

Im running 1k tunes at the moment. I miss my 3000 tunes that blew my gasket. !

How do you load more then ONE tune?? All I see is STOCK, Custom 1, and Custom 2... What is what? How do you know which is which??

 

personally instead of downloading tunes just find what the settings are for comp tune.. 3000 series etc. and tune settings yourself ive found that if you go easy on the timing and dont lower the tps/can min below 30 it gets rid of the surge...

 

Hmmm.. Ill check that out.. I think i need to bring up the TPS min for sure... Whats the CAN min though... I read that they are same thing or something?

 

from what i understand can-bus min is the signal that the ecm is sending to the injection pump if you lower either the tps or the can-bus min to much you will be overfueling the motor way to soon causing surge in the lower rpm range

 

Thanks for the tunes.

 

I just talked to the support guys @ Quad. They are going to send me a new tune tomorrow to try out. Since my truck is surging at like 12% throttle when the TQ converter locks at 50mph

 

try adjusting the APPS and make sure the voltage is within spec
