How "high" could rail pressure spike if these tables are modified to help with LBZ defuel around the shift points. This is not a street truck/daily driver question - track only, purpose built trucks.

I bought a 2008 6.7 Cummins that was tuned using a Smarty 67 box tuner. Having reloaded the stock truck tune back in is it safe to flash in an EFI Live tune? I do have what I know to be a "clean"...
I answered my own question by looking back at table B1115. Gonna dial that up starting at 20% throttle opening.
I am back on stock injectors for the moment and I am rusty on my tuning basics. Holding the foot brake, I feel that I should see a higher EngTorqRef since the truck leaves very soft. Here is a...
Been data logging MAF pids along with fuel while staging and launching (I have a 6" diameter intake).
At 25% throttle position (2094rpm, 45mm of calc fuel flow, around 130mpa of rp, 1250us pulse,...
I removed/replaced the factory coolant tank on DMax. I have the same DIC message. I have looked briefly with a SnapOn Solus Pro to see if this message can be deleted and have not found a...
Thank you - one less thing to be concerned with (as far as tuning goes) is fine with me.
Trying to educate myself on any potential issues that I might encounter with the MAF sensor when I go up to a 6" diameter air intake.
A little background on my truck:
07 LBZ Drag Race project...
Start with trans input & output shaft speed, tcc slip, throttle position, gear, engine rpm, trans temp, tcc duty cylce. Do this on a full pass and you can use the frame counter to overlay your...
The Co-Pilot is not a cure for lock-up issues on LBZ trucks with loose converters. The Ally Locker has worked well on my truck but It would still be very benefical to have the ability to work with...
When I removed my AC I get the same code stored. It doesn't throw the CEL and I don't think it will hurt anything that I know of.
What is P2510?
Anyone have any luck with tuning their lock-up controllers? I know the Brayden was working allowing us to adj the lock-up speed, boost threshold, etc.
When you get it dialed in bring it to Centerville or Tulsa and get some time slips and WOT data logs. Plus running it down the track is a lot more fun than the dyno. Some upcoming diesel events at...
538hp is stout. Keep it up. Nick is the man with EFI Live - he can get you where you are wanting to go.
Me - I am a hack...every good thing that has happened with my truck has been by Nick's...
I may be able to help. What ECM and TCM tunes are you running? I know we have posted back & forth on Diesel Place. If you are looking for total tuning help give Nick @ Duramaxtuner.com a call. He...
Just needed some re-wiring (only needed to see MAP sensor from the main ECM harness. My truck was not happy with the pass-thru inline harness. Once we took that off everything was back to normal.
...
I need help with my 2wd burnouts and launch at the line. I was thinking these tables could be tweaked to help with this. Anyone ever tried this or have something that has worked for drag racing?
My lock-up controller needed lots of tweaking before it would not throw codes or limp my truck. Brayden walked me through it and I now have it where the truck is happy with it on there. I am...
I installed the first Lock-up controller and it made my truck run extremely rough and throw codes. Turns out it was sent out with the wrong inline wiring harness for my truck. The replacement...
Jody,
I just found they had one this morning by reading the thread that Trent posted on DD. Apparently these are the Turbo Brake controllers that can manually command lockup and use PWM on the F...
I just ordered the Lock-Up controller from Fleece
Thanks for the diagram. It is essentially what I will be using.
Did you try it at WOT? Did it lock the converter w/o limping the trans? My thoughts were that if it did work at WOT then I...
I should have the switch/wiring diagrams this week to attempt manual lock-up. I will post up my results. If the switch works, we are going to start putting together a simple microcontroller to help...
Anyone care to share any wiring diagrams and schematics for the 6spd TCM and wiring harness. I am at the point of sitting out the next few races until I can get a lock-up switch or controller...
I have tried raising & lowering the min/max apply percentages. As previously stated these will really firm up the lock-up at part throttle. I have left the max apply percentages around 95%. I am...
