Allison Standalone Controller

[YAKPERFORMANCE]

I have been working for the last month on a Allison 1000 stand alone control system for BKFABWORKS. After a Few revisions but now I have a working setup that is a little different than what's out there. The system is based on a LLY Duramax but could be reworked to be based off a LB7 system. It uses the ECU, TCM, and a BCM I had on hand for tow haul control. The system uses minimal inputs to the stock 1995 5.9L 12V its going into. A couple being 12v constant, 12v switched, ground, brake pedal input, reverse light trigger, crank signal, mil light control, and 4wd sense. Optional inputs are Tach & VVS which can be used. The OBD2 connector has a jumper along with the APP sensor which go into the cab for Diagnostics & or running a CTS or similar device for live data. I left a few sensor inputs to the ECU such as boost/map, baro, IAT, coolant temp, fuel pressure, fuel temp, annd oil pressure for use in the 12V Cummins motor. I rescaled the engine side of the calibration to delete items not in use and rescaled some sensors to a appropriate scale with the 12V Cummins such as fuel pressure since we can only read going into the P7100 which with the air dog should be around 30 psi max. Here is a little log of where Im at it will be installed soon on the truck and any adjustments after will be made on the truck.

The Allison side of the harness is set up for a 6 speed 2013 LML transmission the controller is a AL5 and will use 1-6 gears and has the tow haul option enabled I used one of 6 speed conversion valve bodies and a range sensor for testing on my bench. I remapped the TCM for the 5.9L Cummins engine which does have a 4k spring so we should be able to push 3200 no problem. It was quite a feat getting it to all work, I started with a AL5 only harness but with the AL5 I was having issues reading the TPS since it was set up with my GM 6 speed conversion file. Now I'm not 100% sure but but im pretty sure it was reading TPS but EFI Live doesn't have a PID for the AL5 TPS input for MD applications. So in the end I reworked the harness and added the LLY ECU I had on hand and a few other parts and boom a working setup with proper tps.

I attached some pics and logs of the system I'm really happy I could get it working I wasn't sure what could and not be done as far as making a like OEM system. In the log I cycle the pedal, I cycle the tow haul switch, and cycle the range sensor.

The swap harness was designed to mount on the driver side fender well area behind the battery and I laid it out on the bench similar to how it will mount on the truck. I will upload some pics as well just cant wait to get it shipped annd installed on the truck. The ECM had a DSP5 on it to start with so I left it on there but might go to a stock OS and move my changes over.

Here are some photos of the end result looks like a lot but once mounted it should look like a normal OEM harness. If anyone wants me to build one just let me know it took some time but going forward I have everything recorded which will cut build time in half if not faster.

I would be interested in more details about your setup to use behind a 6.7 cummins in a 2007 Yukon XL 2500 I plan to swap. Shoot me a PM with more details on your setup with cost to get it setup..

I have since done more than a few now and each setup has been different. This was the mark 1 version of my full harness builds FOR A 1995 Ram Cummins with a 11+ Allison 1k behind it . I then did a couple standalone simple setups with just a TPS and a gen 3 & 4 TCMs. The latest build I'm using a T87 15-16 Allison 1k controller and a 2015 /2016 Allison 1k out of a GM 2500. It will integrate a newer ECM and use GMLAN for its coms and OBD2 protocols. What I like about these setups you can a monitor such as a CTS or other monitors to view data on the go in older trucks as well as trucks already equipped with CAN. Your Suburban being a 07 is a perfect candidate. I just recently did a 2010 Silverado 5.3 that was swapped to a 4BT ad the customer was able to retain all of his interior systems paired with a Allison a fun cool daily that he has had on the road for more than 6 month now. If you would like me to go over what we can do with your truck you can contact me at [email protected] I'd be happy to go over a few options with you. I personally like using OEM systems to drive transmissions this is due to no one does it better than the OE manufactures that put tons of time into their R&D as well as there systems i just tailor them to different applications for a like OEM feel when complete.
