ive had this one sitting on my hard drive for awhile and seeing as i was ordering others and it only cost $7 for 10 why not.

Its small, Mega2560, 3 Injector outputs and 4 ignition outputs, all the usual protected inputs (tps, coolant, Map, IAT, O2) includes clutch input and Flex fuel, internal map (Yes i hate them, but i cant argue with the customers), fan, fuel and tacho outputs, 1 LC output, can use VR and Hall triggers, Plug in VR/Optical conditioners, selectable 5 or 12 volt ignition output signal, Robust Buck converter power supply, connected with a 26 pin TE Superseal connector.

I made these for my personal project, 6 cylinder but only has 3 inlet ports so i only need 3 injectors, but it could run a 6 cylinder in paired injection, 4 cylinder paired injection and sequential spark, best use would be motorbike applications, Im thinking of metal case and potting them (sealing up with resin) for total water proofing.

Nice. 8-) I have a soft spot for minimalist boards. I wouldn't let the MAP thing bother you, as with a solder jumper and 3 holes, the option is to run external MAP and now the on-board sensor is internal barometric. From that perspective, the option is actually to enable on-board real-time baro by adding an external MAP, either through an unused pin, or small 3-pin connector (GX-12 series?) similar to this example in the Wiki. Secure and weatherproof-capable. Just throwing ideas out there. :)

So i Bought a Micro from Nick.
It's mounted on my GSX1100EF.
The last days have been wiring and testing, updating firmware.
Calibrated TPS, IAT and CLT, then i hit a snag when checking timing, no ignition....

Turns out my BOSCH 211 igniter had given up the ghost, had another one i switched in and i get tiny tiny sparks.

No filtering.

Enough for "zeroing" the ignition.
So i can't thank Nick enough for beeing there for me. (Even though he's on the other side of the planet from me)
Shop with confidence.

Yes this was updated long ago to 4 injectors and 4 ignition outputs and lately speeduino v0.4 pin compatible.
Even a Limited edition "Ghost" version

Micro is all in one board (MCU is part of the board) with only 4 injectors and 4 ignition and the standard low current (fuel, fan, tach, spare).
the Basic is a Card ECU now that can be used on PNP boards, But does have its own 26 pin board for universal install, it has 4 injectors and 4 ignition and up to 4 additional high current outputs and the standard low current (fuel, fan, tach, spare).
they all have internal map etc.
