Welcome all to a bit of a thought experiment. While diving down some rabbit holes during COVID lockdown I had a probably crazy idea that I have only shared with one dear friend. It involves a Lynx DCOE manifold, a Megajolt ECU and a Jenvey Heritage DCOE throttle body. You'll have to hear me out on this.
First of all, on reading up on Fuel Injection, I was surprised that even with ITB's there is really no timing to the squirt - it seems that in all but rare circumstances - all injectors are fired as bank and all that varies is the metering (duration) of the squirt. I believe this is because - that at a few thousand RPM - the intake cycle is so fast it would be damn near impossible to hit, and would require a really high volume injector anyway, just to keep up. Anyway, let's not get too sidetracked on this!
Enter the Lynx manifold. With its pairing of ports 1&4 and 2&3, it is supposed to give a less lumpy signal on the Venturi's - which gets a bit moot at high revs anyway. Now let's pair this with a Jenvey Heritage and now we have a solution with fuel rail, injectors and throttle position sensor all packaged in to the one unit. All OK so far.
But how about running this with an ECU that has the option to fire 2 banks of injectors - independently. Could we set such a system up to fire each of the 2 injectors in the Jenvey in alternating cycles? Does the Lynx twinning of alternate cylinders give us enough space to effectively "time" the squirt for each cylinder?
I wouldn't have brought this idea to light - except that there is a single Jenvey Heritage on FB Marketplace for what seems a reasonable price. Now if only I had a Lynx manifold, and a project that might benefit from such a set up....
