Strange project.... will MS work the way i am hoping for it to run?
I am building a mega-low-budget build with shit that i mostly have.
The build will consist of a Pontiac 400ci engine in an FC shell along with a few other trick parts to make all of it legal for race-only use. I will be fabbing up a 100% new intake manifold for fuel injection and i want to control spark with MS too. From what i understand, if i have a crank trigger wheel and sensor as well as an IAT sensor i should be able to do all of this? Is it possible to get sequential fuel and spark on the V8, or would it be banked injection and spark? I will be getting more information as the project continues but i hope to get the ball rolling on the drivetrain setup. Matt |
You can have sequential fuel and spark, but you need to buy a MSIII daughter card.
Ms1 will be bank injection, MSII can do semi-sequential on a V8. A standard crank trigger wheel I.e. 36-1 will get you going, but you need a cam trigger for sequential injection. |
how would you run a cam trigger on a pushrod v8? LOL
a 36-1 wouldnt be enough since there is no cam advance or something similar to VVT? |

If you do a good job with the intake manifold I might want one also. My Pontiac 455 needs Megasquirt one day. 1-8-4-3-6-5-7-2 |

So cam phasing would show the ECU that it is in compression phase and the trigger wheel would tell the ecu what degree of rotation the engine is in?
or have i not gotten the concept yet? i was under the impression since the cam timing is locked with the crank by the timing chain that a trigger wheel mounted i could offset the missing tooth so that the ecu could fire cylinder XX at 1.25 teeth past TDC from strictly the crank wheel. |
That's exactly correct what you say. But that doesn't preclude 36 teeth on the crank from not being enough.

There are also a few that have honest to goodness cam angle sensors and run distributorless ignition (Explorer V8 and GM LSx for instance) VVT is not common in a pushrod V8, though there is 1 that I know of, and possibly others I don't. |
