Hi,
I recently aquired an L-Jet EFI setup from a friends '75 Manta, and I have almost everything from the system, except for the distributor and the thermostat housing (which includes, of course, the sensors and Aux Air Valve). I have a source for the thermostat housing and sensors, thanks to Jim at USAOpel. This system is part of the pieces I'm collecting for a 2.0l engine build, hopefully for next summer (my budget and the US economy willing). But, as I was starting to take things apart, I found that the ECU circuit boards had a few components on them that were bad, including 2 resistors (that are corroded bad enough that I can't identify the values), and a transistor that looks like it may have blown (at least this one I think I can ID). So, my questions are these:

1. Is it worth it (and possible) to fix the ECU, and then get the stock system into running order, or will it be better to just trash the ECU, and go straight to a Megasquirt system?

2. If I do go w/ Megasquirt, will I still need the '75 Thermostat housing, or will the MS sensor requirements make it just as easy to keep my stock '73 thermostat housing? W/ the MS option, I plan on using a Nissan TB, and an aftermarket IAT sensor. I'm guessing I'll still need the '75 housing, for the cold start requirements, but I wanted to be sure before I bought one.

3. W/ the MS, can I get rid of the Air Flow Meter, and go straight from the Throttlebody to a cold air intake (probably a K&N cone filter)? If so, does MS have a way to handle the fuel pump shutoff, normally handled by the AFM, if it is removed?

I don't think these questions have been answered in previous threads, but I apologize if they already have been. I've spent hours nd hours using Search to try and learn as much as I can about the EFI system, to decide if I want to use EFI or carbs for my engine build, until my eyes were crossed.
My goal is to have a strong, streetable, reliable engine, w/ maybe 150HP, and I want to figure out if EFI can help me achieve it.
