Hi there! My name is John and I'm also a Perth guy. I've been dabbling with EFI off and on over the years and have done a carburettor to EFI and multi-coil conversion on a Charade turbo many years ago... (using Wolf3D) and recently built my first rotary engine managed by an Adaptronic Modular ECU. I've always been a tinkerer and have a pretty sound understanding of EFI on a practical level... but not so much on a hardware level.My curiosity has led me down the speeduino path and I built one from a kit but never put it to use... (actually gave it to a friend for his MX5) Unfortunately I had to move the rotary on (ridiculously impractical) but have since bought myself an EK civic and I'm currently in the middle of swapping from D16 (non-vtec) to a B16A2. I like to do as much of the work as possible and I thought the icing on the cake to this project would be to try a DIY ECU. From what I gather the distributor uses an optical pickup for engine position but instead of using coil on plug, it retains the distributor for spark distribution. (I think there is a sync signal available so like to move to coil on plug)
Just wondering if you could explain to me what your latest build is (that would suit my application) and how your offering differs from speeduino. I'm keen to know and understand what it is I need to purchase from you to get a running engine...
Thanks heaps for your time! John

Hi mate, Cool :-) sounds like we have a lot in common tinkering with ECUs! Rabbit ECU V1.3 is the main board of this DIY ECU. It has the legs to be expanded into an ECU that can run just about any modern engine because it can be upgraded to direct injection, drive by wire throttle and multi-channel variable valve timing with simple plug in hardware changes. Also for your application it has an onboard variable reluctance trigger adapter. Your Honda I'm pretty sure will have a magnetic multi-tooth sensor. In your case you just need the Rabbit ECU V1.3 and an Arduino Due as the controller. I don't really have a comparison for you to be honest I don't spend a lot of time with the other DIY offerings. I mostly concentrate on what I need to get my own projects going which is a handful in itself! To get up and running you just need: 1. Rabbit ECU V1.3 main board about $140 2. Arduino Due non genuine $15, genuine $50 Optionally you can get: 3. Rabbit ECU enclosure $50 4. Rabbit ECU wiring kit $50 5. Wiring harness plugs $30 These all sell on Tindie, or I can send links on the parts. Alternatively if you like crimping wires I can send you some terminals!
