I've thought about doing a Megasquirt for a while now to replace my carbs. I have a Mallory that works great, so to keep the initial cost down as well as keep it simple, I want to do fuel only, but have an upgrade path available for ignition later. Ideally if this could be done for under $500 that would be fantastic.
So... What is the easiest, cheapest, most simple solution for induction parts? Throttle bodies, injectors, TPS, etc...? Which MS unit has the flexibility to do fuel now and ignotion later without starting all over again with a different ECU? Engine is a 2056 that is built on a 1.8 case and heads with a 2.0 crank, rods and P/Cs. Currently running dual Weber 40 IDFs.

I've used Microsquirt. Its not too difficult to learn, but as stated you cannot change out components. I don't really have experience with any other PEFI so I have nothing to base the experience off of, but I would definately use it again.
The only part I didn't like was that the computer could only support 2 fuel and ignition outputs. I would have prefered 4 for sequential injection/ignition, but batch fire works fine too. I used it on a bike motor, and the only other annoying feature was that I couldn't get it to read the stock Honda cam position sensor. Since you are limited to batch firing anyways that wasn't a big deal. It only took 1 or 2 more rotations to sync. |
