EFILive's collaboration with Oz Tuner and BT DieselWorks delivers Body Control Module (BCM) flashing for 2007-2014 GM Gas/Diesel Trucks, SUV’s and selected Cars. BCM reading and mapping are not available in the EFILive software, and are not planned given our development focus for 2017 in supporting a range of new vehicles and platforms.
Brayden Fleece and Ben Tyler developed a range of BCM programming options and approached EFILive for exclusive flashing integration to negate the need for independent hardware. EFILive was excited to take on this challenge integrating their internal product development into an EFILive tune file format.
This joint project now sees BCM programming a reality and readily available given tune files can be delivered remotely utilizing the EFILive BBX Quick Setup options. Using an EFILive TCM VIN License slot , BCM flashing is complete in less than 20 seconds. Flashing for additional GM BCM types will likely be added in the coming months.
Oz Tuner's initial release delivers tuning solutions for the following functions with additional development currently under way. Please contact Oz Tuner directly for further information.
This software reads and modifies code and data for engine computers (ECUs). Improper use of this software or errors within the software itself can cause engine damage and/or render the vehicle's ECU non-operational. Many ECUs can only be reflashed a limited number of times before the flash memory is no longer functional.
- Remote Vehicle Start timer Extend (10-30 min) (Unlimited Restarts) (requires ECM Reflash).
- LED turn signal compatibility (Eliminate fast flash when LED’s are installed).
- Add manual high-idle based on Cruise Control & Parking Brake (requires ECM reflash).
- Add Manual DRL Control for Canadian/Export Trucks (DRL Override).
- Add Manual Headlamp Control for Canadian/Export Trucks (Manually Override Headlights).
- Fog Lamps on with High Beams. Door Chime Timer (Limits chime to 30 seconds per event).
EFILive would like to thank Brayden and Ben for their hard work and commitment to drive this project. Without their drive to create and deliver BCM mapping, BCM flashing would not have been considered.
Do-it-yourself ECM/PCM Reprogramming (OBDI & II)
If you decide to get into programming for yourself, there are a few questions you need to ask yourself. First, you need to ask yourself if you are planning on keeping your current powertrain configuration. If you don't plan on making any other changes to your vehicle, it would probably be less expensive to let someone program your computer or chip. The obvious reason here is cost. Should you be one of those 'hands-on' type of people, or your powertrain is constantly changing or being upgraded, then doing your own programming would probably be the least-expensive alternative. Below are a couple of links of good technical articles that explain the basics of tuning a vehicle computer as well as what special tools and equipment are required to do the job.

To reprogram most GM OBD-1 chips, you will require appropriate tuning software.

You will also need an EPROM programmer and/or UV eraser
For those of you using the 94 and later LT1 engines with the flashable PCMs, you will only require software from TunerCat or LT1edit as well as an interface cable. The 'ALDL' cables be purchased online from other vendors for as little as $50 or you can build your own for less than $20.
NOTE: OBDII Vehicles are not currently supported by every editor.
I use the one above personally and it works great on OBDI LT1, TBI, and TPI vehicles.
Most laptops running on battery power may not have enough internal power for the adapter. Or the power supply may be too noisy for stable communications. I have found this to be the case with some PCs or laptops which is why I use this design.
There are quite few OBD-2 custom tuning software packages on the market, depending on what vehicle you have. Most of which can be found by a simple search on the internet.
