This would allow you to have a totally stock ECM and totally stock fuel system with just add on componints to be totally tunable and easily changed in modules rather than an entire system. The only draw back is that the right hand would not know what the left hand was doing so you would have to be the smart one in the middle to teach everthing to play nice. |
My idea was to make it to where the MS (Megasquirt) would only supply fuel during boost conditions. I don't know if you can tune it to where it only comes on then, or tune it via fuel enrichment by RPM's, then let the MS 2-bar MAP sensor take over. However, I believe from what I've read about MS is that it
can be tuned in both ways i.e., tune for operation during boost only, or tune for fuel enrichment at any given RPM's, or both. And the best thing about it is that you can run a TBI fuel system as well as a MPFI system or whatever you want to run; it's all in the software that is supplied.
As for the MSD boost timing controlls, that is already taken care of. All I have to do is exchange it at Jegs for the non-MSD ignition system, i.e., the boost timing controll system for non-MSD ignitions.
Once all of that is taken care of, I have some welding to do...
