Oh cool, that saves me some trouble then.

nemu would be a better buy

I might agree with you there blo0d.
Also a used AEM series 1 is cheaper or around the same price depending on OBDI or OBDII.

megasquirt is awesome, I don't know why more people on here aren't using it. It's A LOT cheaper and you can do everything that the more costly units do. Especially if you know how to mod your board.

Support and ease of software are why I would pick AEM over that. I do like MegaSquirt, they have come a LONG way and that plug and play option is very cool. I love that the S13 shared ECU plug with B13 so we get more options (ala PowerFC).

The more I learn about hardware and the process of actually designing an engine control unit, and the more I learn about firmware and the process of controlling that hardware, the more I like MegaSquirt less and less.

The more I learn about the company's practices and "morals", the more I like them less and less.

The more I learn about the alternatives on the market and the alternatives on the horizon, the more I like them less and less.

Speaking of MS, has anyone used their trigger wheel on an AEM or other EMS system? They offer a 50mm and 54mm and they are only $25.

I saw those wheels. In theory, they should work on any ECU as long as the ECU has sufficiently configurable trigger settings. Obviously some are more able in that area than others. However, the pattern isn't a real great design and I wouldn't use it if I didn't have to.

If you notice, they mention that with MS you have the choice of either using the inside ring of slots to replicate a 21-1 crank trigger output which will give you a quick sync and a quick engine start but not sequential ignition/injection or you can use the single outside slot as a cam trigger output and get sequential ignition/injection but you won't get the quick sync or quick engine start.

=/



If you want to see what a trigger/CAS disc looks like designed for the quickest possible sync and start, and a good balance between resolution (for accurate sequential triggering) yet high rev capable, this is what it looks like:



This obviously requires the wheel decoder to understand that there may be different widths to each slot, something the OEM ECU is prepared for, but not many Standalone ECUs are that versatile. Many of them make due by ignoring the width of the slots on OEM discs.

I'm not fully convinced their 54mm CAS disc option will even fit into an actual CAS housing without a little modification.
