Does the autotune only work on the "A" side? I have an older EC2 that doesn't have the required hardware for the A to B copy. So it would be nice to autotune both sides. Also I assume that it only tunes the MAP table and none of the other variable parameters (timing, injector flow rates, etc.)? As a side note: My original EC2's default program allowed me to start the engine, but required allot of tuning. Last time that I updated, the stock programming was very close and only required minor tweaking. This time it is again close enough to start, but needs allot of tuning yet. Todd (wondering if Tracy's holding back the Autotune until the datalogging option is added :-) Yes, I do, but it works on the A computer, and my A computer is still kaput so I cant test it. :( I have (another) strange scenario where I cannot start on A. If it runs at all it pops and misfires on what seems like one rotor. No throttle response and 800 rpm max. Flip to B (which has the older version computer chip) and the engine starts and runs purrrfectly. Once running on B I can flip to A and it runs fine provided I don't go below 17 MAP. If I do it cuts. Go figure. I'm guessing at a compatibility issue between my fairly old rev 0.9 EC2 board and the new chip / software. Tracy is going to ship me a replacement board as soon as he gets back from Sun & Fun.
