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.

Most modern fuel injection systems are tuned to the engine that they were built for. This would make it a bit more difficult to fit to a type 4. Also most newer fuel injection uses a mass air flow meter, instead of manifold pressure. This would mean that you would need to bring the intakes from both sides of the engine together, and feed them through 1 MAF. It could be done, but I think you would spend far more time and money trying to get something from the junk yard to work than to get megasquirt or something similar. Keep in mind that any fuel injection system will need to be tuned, and even a junkyard system may require a $250 programmer, whereas the megasquirt can be programmed with just a pc.

Doesn't the type IV have a single TB to common runners now? Replace it with the TB from the junker along with the injectors, MAS, O2 sensor and ECM,Transfer the dist guts and fire it up. If you use everything, the sensors on late model stuff will fatten or lean the fuel via the O2 Sensor right? Maybe..?? I'm an old school carb guy. Give me three Holley's or 2 center squirters and I can make it run in the 12's. Injection... (IMG:style_emoticons/default/wacko.gif) If your just replacing injection with injection and the cam is correct for injection, (short lift long duration) I can't help thinking this would work. There are some very smart injection systems built by really smart guys for mass production autos. I think as long as the distributor works the rest of the system would self adjust. |
