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.

Megasquirt is pretty cheap and easy, and you can use most of the stock parts. On mine, I use the stock injectors, pump, Intake Air Temp, Cylinder Head Temp, and relay board. The manifold pressure sensor is built into Megasquirt, so thats all you need. One of the main points of this exercise is to eliminate the expensive stock parts. My thoughts: The ECU setup is going to eat up most of your budget, so you're going to need to use as many stock components as possible. The TPS is not compatible with any new system. Throttle bodies will be out of your price range, and without a bunch of R&D, stock FI setup will be your best bet. Yeah, I know. The major expense seems to be the intake and TBs. what cam are you running? i've been thinking about this too... No idea and the cam was the only thing I couldn't find in PO doco was cam info. I assume it's stock though. Sure doesn't feel too wild. Again, your carbs can be used as TB's, change the manifolds for a pair that has inj. ports. Or sell what you have to buy TB's A stock induction can be had for a fairly low price a will work fine. you can get away with NOT using a TPS but they are cheap and easy to retrofit to the stock TB. There was a suggestion to get an MS2 they are great units but that drives the cost up almost double. For your app. , the MS1 is more than plenty and will give you the opputunity to run spark later. ask me how I know( MS1,V3.0 running MS&SE with a 36-1 trigger wheel and a Ford EDIS coil, BTDT, it's in my sig.). Your original goal is to do it for $500 or less, simple answer is , yes you can. |
