They're air pumps.. not timing gears.. the clocking isn't that important. I assume it would change PSI output between the two slightly but nothing that would be likely very noticeable or adjustable...

I think I'd rather kill fuel than fire, but as pointed out depending on circumstances leaning out could be an issue.

Just a theory, but I wonder if you can't power the coil with two alternative...

Reminds me of when we were kids we'd run an engine up to speed shut off the switch let it spin down and load up fuel and turn the switch on causing a huge back fire POP... this is essentially what...

Looks great!! Bet it sounds great too.

Have you ever considered a FMU? raises fuel pressure at a determined ratio based off boost to push more past the injectors. For example 1:6 one pound boost raises 6lb fuel.. Iirc thats what Paxton...

I had worries that it wasn't as easy as that seemed. I read a thread not long ago where a fellows solution was to use a 1 bar map and just up the fuel in the 100 setting only, basicly I suppose any...

Thanks for that link, lots of good info there.

Very cool! I've read that you can rescale the values for a 2 bar by cutting them in half but the chart I saw comparing 1,2,&3 bar maps weren't exactly half. Do you recommend a formula too use?

Ah that makes sense, Thanks Shooter.. I still cant this plug in the diagrams as a complete pinout but I think there's enough info to make it work. Correct me if I am wrong, I can basically cut this...

Ok, so after being confused a good while I found out that what i have thought is my Aldl is not an AlDl and that there is supposed to be something that plugs into this plug I have and that has the...

Cool stuff looking forward to seeing how u tune for the boost

Here's an interesting question...

Ok my Turbo is a draw through style meaning it sucks air through the carb or throttle body. Since this is the case, if my vacuum port is before the turbo,...

Thanks Dave that should be very useful.

I'll check out those turbo ecm'
From what I understand my ecm is capable of multi port with minor mods.. I want to eventually step up to mpfi but wanted to use the TBI as an easy learning tool.
My...

Id much rather not do the crude stuff... I've got an ostrich on the way and have been studying the $od bin and xdf file for a 4.3 v6. The erratic readings I'm getting now are because the fella who...

Ok, that explains A LOT, thanks a million! Where can i find this info at myself?

I have two chips that came with all my TBI stuff for my conversion. The guy i bought it from said one chip was from a 4.3 v6 and one was from a 5.7 v8 both m/t pickup truck... I really dont think...

Delcowizzid, What ecm and bin do you use for your engine?

Is it normal for tunerpro to not hold steady values during datalogging. Mine is pretty dang rough, Idle is bouncing all over ect.

Well i think I am hooked... All of this is very intriguing to me. Does anyone wanna look at a couple of XDL files and tell me what i might initially try to smooth-en things up until my ostrich...

The more i think about it the more I am considering going old school and putting a resistor on the 1 bar map to limit voltage while in boost and running an extra fuel injector off a Hobbs pressure...

Ok that clears up quite a bit, I am having a hard time finding much info and files on the 6395

Just found this:
16168625/16197427/16196395/16156930/16245358

Thanks Dave, in the bin sticky it says

Hi, my project is a 52 Chevy that I installed a 250ci inline six in. I have a 79 Buick regal turbo unit mounted on the intake for fuel delivery and a throttle body from a 4.3l v6 i figure that would...
