After a 4 plus year losing fight with Megasquirt I decided to try another tack.
I will admit that when I began the odyssey with Megasquirt I knew very little about after market fuel injection. It was a worthwhile and fairly expensive learning experience. But I never learned enough to get it right and consistent.
I pulled all of the Megasquirt equipment and wiring, except the fuel pump and surge tank.
Ordered a Holley Sniper TBI 2300, I think this is the answer. I mounted it to a Weber DGV manifold with a home made adapter, routed the fuel and wiring (2 hoses, 4 wires), it fired up on the first crank.
If you?re not familiar with the sniper it is basically a 2 bbl carb replacement that will self adjust to just about any engine up to 350hp. All of the necessary parts are built into the TBI body (TPS, IAT, MAP, IAC and the ECM). The kit also included the O2 sensor and ECT sensor. There are 4 bbl models for even bigger engines and single bbl for smaller engines which might have been adequate, but someone on the site says that overkill is always better, a philosophy I embrace.
The biggest obstacle I ran across was the throttle linkage (this is mounted in a ?58 Duett with a B20). I utilized the throttle cable linkage from a 144E.
I haven?t noticed any real power gains, but it starts right up, runs well, doesn?t bog down or lug and has a nice even idle.
There is customization possible within the software, but it runs well out of the box.
