I have a client that would like to disable DPF on their 2008 Duramax because the habitual limp mode for regeneration is a hassle. A lot of these trucks are coming up on 2nd or 3rd hand owners. I'm...
2.23.272 and 120. Is there a way to go back to 112?
Here's my deal: I don't get a different truck to tune, but maybe once per year. I'll tune mine at least once per year just to try something different. A few years ago I had requested an old Beta...
The stock defuel is about 90% of the actual fuel just before the shift is commanded. I've always figured that when we increase the pulse width it's like making a 60 quantity into a 70 quantity, and...
what about the pressure regulator and the pressure relief valve?
Did you modify the input voltage vs. pressure table? Have you scanned with a chart for desired pressure and actual pressure?
I was scanning a friend's truck and I couldn't log Desired Fuel Pressure, Fuel Rail Pressure, nor Throttle Position. Has anyone ever experienced something like this? The sensors or PIDS were...
I'll share with you guys what I have done. I start off by copying with labels from the pulse width table into a spreadsheet. I paste the stock PW table into 3 different sheets. Delete the values...
This is what I would do for a starting tune: Go to your pulse width table. It's assigning a pulse width to a quantity, and ranges from 0 to 110(?) Multiply the pulse width values from 0 to 10 by...
You haven't stated which engine or what year you're tuning. You're an "Advanced Tuner"??? ...of what gas engines??? Member for 4 years already??? I mean, come on, you're killin' me here man. ...
1 pilot is the basic pilot injection to reduce the rattling effect. Basically, it creates a little bit of pressure on the piston as it's rising to TDC in the power stroke. The other 1 or 2 pilots...
I am not sure if I can help you exactly with your request, but the tables in question are called turbo vane control. The values in the table are percent closed. 90% closed would have the tip of the...
I don't think it's just a matter of raising the values. Look at the graphs that compare the new profile with the stock for a particular shift. The profiles have more slope, and there is more gap...
...and by popular demand. Here ya go. You can thank me, just not blame me, hahaha. It has helped me to see and have an overall control of edits for the shift points table. Use the tabs from left...
Cool! Welcome aboard. Since I helped sell a license maybe technical support would be willing to send me the earlier BETA, so that I can do what I need to do. BTW, I'll share my shift point...
You could do it like that. How about you select the remainder of the cells after the "50 and 62%", and multiply them by .9 (a 10% reduction)? Pay particular attention to the speed at which you are...
Yes, under the transmission settings for shift points. Lower the profile for the 6th to 5th shift for the speed you're setting cruise control. I usually raise them all and create a larger...
I compared your file to mine, and you have more parameters. I'm pretty sure your ECM is that of the LBZ. Maybe it's detuned from the 360 HP, but you'd have to find out from someone with a 360 hp...
Where did the tune repository go to? I haven't been able to find it.
I've been messing with that table myself, and this is what I experienced: When I increased the quantities the truck had better response from the pedal. It seemed like it just took a little bit of...
Research either of these two sites:

What you're saying sounds vaguely familiar. Perhaps the hardware is that of an LLY,...
If it's a 2006, it is an LBZ.
I believe it's the torque management tables. I would raise the entire table by a factor of 1.05, and see how it does.
I don't know, but it stores the PIDs for the last vehicle scanned. Maybe you need to be plugged in and at least "connect" to the vehicle. I have only ever scanned my one vehicle, so I'm not sure...
Can anyone figure out why the boost pressure would surpass the MAP? Check out the pic of the chart. Would this indicate that I have a high pressure leak in the CAC? Thanks for any feedback.
