Nice work. I too am with mark and just cant afford or justify the high cost of the tuning software for the 411. Otherwise I would be building a 411 system for both my cherokee, and the 4.0 in my wrangler.

So untill there are more affordable options for the 411, I will be sticking with the 7427 in my cherokee, and the stock ecm in my wrangler.

Nice stuff for sure! Basically, the system I designed is completely bolt on (no removal of the timing cover from the engine) and is only a fraction of the cost of the EFI Connection system!

I am using the 4 tooth (low resolution) trigger wheel. To use coils, the 24 tooth (high resolution) trigger wheel is required. Basically, the EFI Connection 24x system is a good option to do coils. Maybe in the future, I'll design a bolt on high resolution system.

The downside to the Vortec PCM (very abundant / cheap) is the lack of software!!!

Really???

Weren't people buying Tunercat's OBDII Winflash for doing OBDII uploads/downloads? There's a nice disassembly of a black box Vortec cal on thirdgen.

Right! I've had the OBDII tuner since shortly after it was released and I've always had mixed feelings about the JET sale. But that's the tuner. The flash uploader is a separate program and runs separately.

Oh nevermind. TC has removed winflash OBDII from the list of available programs. That's too bad.
