Yeah AJ, just thought I might get some additional info over here. See if anyone is using a FAST EFI. How's the big block running?

It's getting there. I'm trying to get a 496 set up right with FAST. My cam's too big for EZ 2.0 and am about to upgrade to the Sportsman ECU.

If you're not getting responses to questions in this section, try the Garage.

Thanks Krats, didn't realize guys from over here wander over there! Hope I didn't bore you too much I'm really slow trying to figure things out. Should of stayed stock, but once I see a cool Mod I have to have it on my truck

AJ how about a Vac can with a pump, wouldn't that maintain a constant 14. I thought the 2.0 was a better ECU because you could moniter timing, along with other stuff like tranny
Congrats on GMOTM

The vac can and a pump would help with the brakes, but wouldn't give me vacuum where I need it: in the manifold. With the big cam, the ECU always thinks the engine is under load because of the low vacuum. It's dumping gas at idle. EZ 2.0 can't tune itself around that.

There's some thoughts in another thread that a single plane manifold may help with this and fuel distribution. But this engine really needs to be tuned to make the power it specs out to.

I feel that when you have a first gen you have to glean info from everywhere you can. And the TPI on yours stands out, and I think that's awesome. Not to mention the wood bed, and so many other aspects of your build. I like your methodical work and the journey you are traveling on your build is great to read about. I appreciate you sharing.

Well, AJ it was just a thought, but you are right. Just sux to buy a whole new ECU to fix the problem! Any suggestions from FAST?

Actually, it was the look of the TPI that I liked,but the old Halibrandts injection unit is what I want someday, converted to EFI, but cost has put that unit on the back burner for a while.On my build thread, I never know if I'm putting up TMI, so I just inject what ever I'm doing. I'm glad your enjoying it, and thanks for the kind words. Didn't know what to expect from a new forum. Some forums get a little rough, but this forum has a lot more info. to offer!

Right now I'm working on the ECU wiring, but mounting them took 2 years to figure out placement, until my son suggested 'C' channel

It's not as bad as it sounds. Talked to FAST and I can trade in the EZ 2.0 ECU. Difference comes out to ~$300

Related to level of detail....keep it coming.

That's cool, didn't know they could help out that way
Glad it's working out for you, your truck looks great

didn't like the corregated sheilding FAST uses, changed to spial wrap from Wire care
Plus the grommet they supplied with the harness was to small. Had to take off all the connecters to slide the grommet on
