After much debate we've decided to continue development of our E38 / E67 custom OS's, but, not in the original form we were testing in 2008.
Initially we had all sorts of features such as switching modes using the V2, valet, output controls. Whilst it worked and was all good, when we did the sums it was going to potentially take 2 days per OS to modify, there is currently 86 OS's supported in EFILive for both these ECM's, so 6 months solid work.....not going to happen.
Instead we've come up with a new concept that is pretty quick for us to implement over many OS's.
What we are doing is via an input pin on the ECM we trick it in to thinking the vehicle is running 85% ethanol fuel and also enabling a new injector flow table. What this does is give you many extra fuel and spark tables at the flick of a switch (B3670, B5114, B5115, B5145 as examples). In reality you would probably have the ECM input wired to a relay output for use with Nitrous (or some other fuel).
What you need for testing:
An ECM pin so you can wire in the trigger to switch fuel modes (the part number is 33467-0005/23).
Access to a 2008 - 2010 model vehicle for testing as these will be the first ones we will work on. 2006 - 2007 will follow soon.
The test vehicle must NOT be a factory Flex Fuel vehicle.
You must be running the latest v7.5.6 (http://forum.efilive.com/showthread.php?t=12014) software, mainly due to the changes made to correctly deal with 2010 models.
You can manually extract zip files in to specific folders.
Keep in mind this is in test stage, do you really want to 'test' on a customers car?
If you are interested please send me a PM containing the following info.
1 - ECM OS's number you want to convert to a custom OS.
2 - Your Email address.
3 - No COS feature requests, they are what they are, no more feature creep!
Cheers,
Ross
