I think the following questions need answers to determin if a Megasquirt could run a BA motor. I would be very supprised if someone has already done it with an MS2.
Does anyone have any info on how the VCT system works? What signals are required to control the VCT, etc. (if it uses a PWM signal then MS2 might be able to do it with some mods).
Does anyone have the pinouts for the coils? Do the coils have internal ignitors (3 wire?) or do they require external ignitors (2 wire?). Either way MS could handle this.
What type of Crank / Cam trigger does the BA motor use? I would assume it uses a 36-1 wheel and VR sensor like the earlier models.
The way I see it VCT is the main issue, Just need to work out if it will be a problem or not. The fuel and ignition can just be worked out once you have the engine.
Cheers

| I believe they actuators are PWM driven in the BA, there is a closed loop around the camshaft position sensor. That said if you wanted to control it as the AU did and just drive it hard at low RPM that should work OK. Otherwise the ECU will have to this capability. |

| Megasquirt has a mapable PWM output (Boost Control) that you can map PWM based on RPM and Engine load. I was thinking you could use this to control the VCT. Just need details like PWM frequency, PWM percentage fully retarded and fully advanced, etc. |

Enough with the aftermarket ecu's for ba's..
its like flogging a dead horse, get over it.
the factory ecu is the bomb diggidy and an aftermarket will never control the vct properly, the vct system monitors oil pressure and temperature to operate the vct, and like someone else said it monitors the actual position of the cams and adjusts the positions, just like it tunes the fuel map with the oxygen sensor. |

| I totaly agree that an aftermarket ECU won't be as good as the factory ECU for controlling the VCT. But Xflow is talking about a BA engine used in a conversion (not in a BA) so using an aftermarket ECU would avoid all the wiring problems with the factory ECU. |
