I'm not sure I'm up for putting my machine on the dyno every time I make a change and then custom tuning an ECU that I already paid a bunch of money for the tuning on. And I own a dyno! Will this ECU be open source so that adjusting maps is even an option? Or will it require you in order to change the maps? Ideally you wouldent have to change the maps, just have a way to simply change basic fueling in case I see a lean spot, or if i'm running on the hill and see that my EGT's are really hot for some reason, or etc...)
I'm really interested in having a stand alone as I think there are a lot of benefits, especially with the timing and intake temp compensation, but if its not tunable to my machine, for anything I want to do to my machine, I don't think its going to be worth it. I'd just end up running a fuel controller box on top of your ECU to compensate. Just as the guys who put new airboxes, pipes, cans need to do on the factory ECU. Just changing a pipe can dramatically change how much fuel / air you need at specific RPM's / MAP's.
This all assumes that under max power conditions your ecu goes to some map that you have already programmed into it. You said in a few posts above that you did not want to rely on sensors in those cases. Well, if I do something to my motor (porting or pipe is the biggest thing that comes to mind) that could completely change the air / fuel requirements at given RPM's, and MAP signals and require that I be able to change my fueling.
I guess the solution to this might be that you offer different ECU's for specific pipe / porting setups, but it seems like there are way too many possibilities for you to cover.
I'm saying all of this as the devils advocate. I think what your doing is awesome and It appears that your doing a very good job. Your dyno facility looks great, and your knowledge seems solid, this is just be best way I know to pose questions. Drives my wife CRAZY. Your still going to talk to me aren't you?
