Found Possible Fix To VVEL

wstar

I'm not an ECU developer, but I am a software developer and I've dug around a lot of the public info about how this stuff works, what UpRev is looking at, and what's possible with Nissan proprietary interfaces, etc. From that company's descriptions on their website, if they could do anything for us, it might be to develop software for us that speaks all the right protocols that's (a) More capable that Cipher, closer to the dealerships' Consult interface, and (b) Cheaper and more available than actually buying Consult. But this would still be basic data logging and ECU controls, it wouldn't be replacement ECU software itself. Not that they probably don't have people of that sort of talent on board, but it's probably not what they specialize in doing (reverse engineering and replacing portions of the ECU software).

What UpRev is doing is exactly that: they're disassembling the ECU's software and reverse engineering it to find out how it works on the inside, and then releasing aftermarket customized versions of this software that allow realtime (and fixed) re-tuning of tables and parameters. It takes a *lot* of reverse engineering and development time to do this and produce a reliable ROM that doesn't screw the car up, and UpRev has been on the task for a while through generations of Nissan cars, and especially for quite a while on our cars.

It just doesn't add up that this other generic company that happens to work on CAN-bus protocol stuff and whatnot is going to catch up and do better than them at this, when it's not even their target market.
