Smooth Throttle for UpRev

wstar

Good question. If you have an UpRev cable, it probably has some sort of license attached to it, the question is which kind. If you go to UpRev - Engine Management, you can download their software there. Either Cipher or Osiris Standard (one of the two, probably Cipher) comes with a License tool that will tell you what your cable is licensed for.

Thanks! Got it. Everything's disabled except Cipher. It appears I am also able to flash the ECU, but not dump it.

It'll be nice to "open source" the throttle control project. Pretty soon flashing our cars is like Android flashing our phones.

It's probably a "Standard" license then. You can probably upgrade it to Tuner, but you should send them a License Report from that cable firmware tool first to be sure.

Unfortunately modding our ECU (or any car ECU really) is never quite as open a process as I'd like. I'm an open source developer myself, but the ECU world is all about trade secrets and warranties and whatever.

Nissan doesn't tell anyone how the ECU works. UpRev reverse engineers it to tease out whatever maps they can, but the deep details they produce (which allow them to make their roms and tools), they keep to themselves so they can run a profitable business, as it takes a lot of money to do the reverse engineering of this stuff.

I plan to continue posting whatever I can about whatever I can learn from playing with the tables in the Tuner edition of UpRev, but I don't think that will lead to anything resembling an open source ECU for our cars. Mostly it's just to reduce duplication of effort figuring **** out.
