MicroSquit Conversion, Giving this a try Options

[Mblizzard]

I am pretty happy with my stock FI. But after seeing some of the setups at Okteenerfest, I thought this might be worth trying.

The stock system is not easy to modify and get things running correctly. I spent a lot of time making minor adjustments by trial and error. While I am not looking for huge HP gains or anything, it is pretty clear that the mods I have could potentially benefit from a bit more precise control.

Going to start with fuel only at this point to get things going and see where it leads me. Any help or suggestions for set up would be appreciated.

I own, run and have installed virtually every product Mario offers at thedubshop. His products are the best I've used and his after sale service is second to none.

The mini cam sensor enables full sequential injection and/or spark. For most folks, it's not really necessary. Sequential injection can on the right motor get a couple more hp and slightly better mpgs, but where it really helps is on motors with high lift & high overlap/long duration cams. It greatly smooths the idle and low rpms. I'm using one with LS2 coils on my race motor that has a pretty wild cam and it idles like stock @ 8-900 rpms. It would never do that in batch mode.

IMHO I would go with one of Mario's own ECUs. It can be used to run sequential or batch injection/spark. It comes with 2 map sensors as well as several other features. It also includes an on-board WBO2 controller!! When I convert my bus to MS, it'll have a Dubshop ECU.

I would highly recommend using a 36-1 trigger wheels rather than a bosch dizzy for triggering spark. The only dizzy I have ever used that comes close to the accuracy of his kit is a Mallory Unlite. A factory Bosch dizzy is all over the place with timing. They can vary by as much as 5-7 degrees depending on the wear on the shaft. Bosch dizzys suck IMHO. There's way better out there these days, so why bother with them to control everything??

I think the crank trigger would be better as well. But with my car having AC I don't think I have the space to insert the trigger. So while it may not be perfect, the dizzy options seem to be what's available to me at this point.

I don't understand why a Dist (with all advance locked out) and a pick up wheel installed would not be just as good as a crank fire set up?

As Mark Henry stated, there is some potential "slop" in the dizzy on Decel. But I think the crank may provide more options and potential with the sensors being more standard there are greater options. But while I am still doing research, the dizzy option seems very valid. If it was not an option, then things like the Mini Cam Sync would not exist.

I am waiting to get the details on the mini cam from Mario.
