Converting a Mazda BP to Honda ECU?
 

I'm considering converting to a honda ecu instead of running megasquirt. Megasquirt just seems like its going to be too much of a pain in the ass and nobody wants to tune it. Does it matter that a BP spins CW and Honda's spin CCW? if i'm thinking correctly, it seems like it would be pretty easy after you adapted the honda distributer.

Toyotas spins clockwise and a couple of guys on here are making it work with a honda dizzy, sensor, and ecu. So there should not be a problem with a mazda motor then.

Why so scared of megasquirt? It is a pain in the ass, but its a great learning experience. What mazda engine are we talking here anyway?

I have some serious complaints about Megasquirt, but it works great on the Miatas. It should, too, seeing as how a lot of the beta testing for MS is done on Miatas. Soooo, B5, B6, BP... if you aren't looking for big drag car power, say keep it at or under 300 whp, I think it'd be more work to fit the Honda distributor.

Ya, I remember seeing a thread on here about someone converting a toyata to honda ecu. I searched for it but couldn't find it.

Its not that I'm scared of it, I just don't have the time for it right now. I'm an engineering student so the time I can spend working on my car is pretty limited. If I went with a honda ecu, I could visit Xenecron for a day and be done ya know. I can't find anyone that wants to dyno tune megasquirt. Its on a 1.8 BP.

I have access to machining equipment so I think adapting the distributor wouldn't be that hard. Am I correct in thinking that all I would have to do is adapt the distibutor, install all necessary honda sensors, then wire it up?

From what ive read theirs a few super easy ways to retrofit honda to anything. Make a bracket that mounts the dizzy onto the exhaaust or intake side cam gear. Cut the shaft weld a 12mm socket to it that presses up against the cam nut lol. VOILA honda dizzy, the rest is just wiring. You also get free halfassed ign advance retard lol.

By the time you adapt the Honda dist, plumb and wire sensors, make a conversion harness to plug in a Honda ECU, etc, you've eclipsed time it takes to solder the ~25 wires a MS needs and exceeded what a MS costs.

MS on a Miata flat out works, and has datalogging that's a ton better than some $1500 standalones.

i agree, a MS install would definately be easier. From a tuning aspect, the hona ecu would definately be easier though, right?

Tuning honestly is tuning, ive run my megsquirt for over 2 year now with great results.
