That is why he can edit things that are not in HPT.

BDM100 module

Here you can see where the software identified a potential table within the hex data, and how to edit it:

Software WinOLS

I'm a computer guy, so I understand much of what is going on here. If I had before and after files to compare a BSR or Westers tune and a stock tune, I could likely identify the tables that they have figured out and replicate it. I'm not going to purchase HPT until they offer more for my car. There is a popular tuner not far from me. I could get him to give me a read of before and after my BSR, then I could start to tinker a little with the code. The setup from EVC is expensive for me just to tinker, but if you guys are really committed to paying for results maybe we could pool our resources and work on our own tune.

Sounds good, only issue is AFAIK the BSR is a completely custom OS. Working on it and the factory/westers may be very different.

How much "pooling" are we talking about?
