Megasquirt III is finally out, and it really has some good specs. The following is the feature list, copied from the MSIII website: http://www.ms3efi.com/index.html
Speed-density, alpha-n or MAF for fuelling calculations
16x16 fuel tables in 0.1% steps with true interpolation and movable rows/columns
16x16 spark tables in 0.1 degree steps with true interpolation and movable rows/columns
Wall-wetting transient fuel control for better driveability
On board datalogging to SDcard (max 333Hz sample rate)
Tuning by serial or built-in USB-serial port.
8 channels sequential fuel (hi-z injectors or low-z with external resistors)
2 additional fuel channels (hi-z or low-z)
8 channels sequential spark (logic level output)
6 channels mid current output for small solenoids or relays
2 'spare' conditioned 0-5V analogue inputs (+2 more raw)
Two wideband oxygen sensor input (external controller required)
(Up to eight widebands supported via external data capture) Anodyne???
GM-style stepper idle control
2 and 3 wire PWM idle control
Closed loop idle control
Closed loop mixture control - ideally with wideband
Closed loop boost control
Various boost control systems (gear, time, speed based)
Two stage variable nitrous control
2 step type launch control
CAN communications to interconnect other Megasquirt products e.g. transmission controller
Supports external data capture boards (e.g. for external EGT boards)
EGT data support (with external amplifier)
Staged injection
Dual fuel (e.g. LPG)
Table switching, (mainly for dual fuel use)
Water/Meth injection
Individual cylinder injector trim
Injector phase timing
Individual cylinder spark trim
Support for numerous OEM trigger wheel patterns.
Magnetic (VR), Hall, Opto crank sensor input
Magnetic (VR), Hall, Opto cam sensor input
DIY Autotune (one of the MS authorised dealers) is selling DIY kits for $305, or a fully assembled ECU for $540. Unfortunately they're out of stock.....
