Re: FrankenFerrari - V12 Ferrari 308

Did the EL stuff make any sense to you? Did not even try opening, more like one day :( Well...its not like you don't already have your hands full so I was a little surprised when you even asked about it....there is a fine line between distraction and help. I like it because I can make it do what I ...

Re: FrankenFerrari - V12 Ferrari 308

Yes and it probably has more stuff than most people need, portions might be interesting though.

If it's not broken it probably doesn't have enough features ;)

Re: More table needed

Stock and HRC ECUs use 7x16 tables, I doubt you'd need more than the current ones. MAF setups I assume? TPS/MAP hybrid Ahhh bikes....the modern ones have tables that small? Even spark tables? Is there a separate GPS and map table that get combined to the 7 point load axis? I've just never had much ...

Re: electronic throttle body control ETB

I really like the simple feedforward (spring compensation)table you've added ...its probably going to want voltage compensation of some kind? I added a version of this to my setup with a 5x11 table to do 8, 10, 12, 13,8, 15V and throttle from 0-100% in 10% steps as a starting point and tested it to...

It has no trouble with this setup, you can just see it tucked in the V on the right. I did switch to pretty light springs in the TBs though Edit: also I use the ...

Re: electronic throttle body control ETB

For converting an existing TB to ETB this actuator from a bmw E46 series works well and gives you a second TPS signal as well.....but its a bit large and draws well over 3A in motion even with no TB connected to it, over 10A moving 12 ITBs.

I dug up a log of the throttle response on my setup....Red and yellow are the tthrottle and desired location. There's a little lag, basically the loop read time delay. The blue line is throttle state switching from normal to idle and you see the throttle move to an idle position, this was testing so...
