I'm surprised that you couldn't get the Fast EZ EFI to work --- it really only needs a tach signal - which can be taken off the MSD box tach driver..... but obviously if the trigger isn't signaling the MSD box to fire correctly - then the tach signal is no good.

I'd have thought a crank trigger assembly off the balancer ala drag cars and many others - would do nicely for the signal. But who knows?

Yes he does!!

John, don't leave us in suspense, we need some engine specs please!

That's what we did.

We were using a FAST XIM box with a SBC crank trigger on the front of the crank reporting timing to to the EZ EFI 2.0 system. Thing is, the EZ EFI takes limited functions. EFI sportsman is "Supposed to work" but when push came to shove, they said it's better to run a distributor, which this motor will get, but then I didn't want that in this Camaro. The LS looks more like a Ford motor at this point...

Funny thing, the Mamo motor is getting EFI Sportsman anyway, but now has a standard LS crank and cam sensor, so it will all run natively without concern for square or sine wave inputs. We went simpler.

Next ones will be ALL GM, no aftermarket EFI.

Motor specs.

It's Chevy orange. Has a chromo crank.

Connects to the TR6060 via a pretty clutch.

Lovely.....



LOL

:)

Oh, it's got 3 figures HP.

Mine only has two, I bet she's a screamer! :lmao:

So, after everything we went through, FAST wants their box back, as they think it's in the ECM.

Holy carp.

Got to love it. Now they say that!!!!

You have no idea. 40+ hours on the phone with them, 2 different engines, 2 ignition control boxes.

I think it's cost me about an LS9.
