Haisley "HI FLOW CONNECTOR TUBES" anyone?

well i am assuming you have done it, so whats the difference? i was taking out crank sensors left and right for a while because one of the bolts holding the tone wheel to the crank was only finger tight, another one was in the pan, and the third one was still tight. so i know what happens when you lose a ckp. what about a cam sensor on a truck with both?
 
My 01 has a cam. Last I recalled I don't remember a crank sensor but it's been a while since I've looked.
 
when i lost crank sensors i had no idle, no start, no run. unplugging had the same effect as taking the sensor out, causing an open circuit

IIRC we were talking about advancing timing to negate the delayed timing effect caused by the larger tubes. I would imagine stacked timing boxes would still be too aggressive, but since the technology exists to write a program, like an edge or tst or any other timing box or smarty for that matter. I guess the question is, why not write a slightly more aggressive timing program for the bigger tubes and see if that has an effect.

With that said, I have no idea what kind of work is required to write a different program with more aggressive timing, and its probably not worth the effort. Its main just a hypothetical question and I figured I'd throw it out there to see if anyone had already tried it.

I'm assuming the boxes are using a FPGA or PIC controller to run the code. Changing it shouldn't be more than adjusting the firmware and re-compiling the code. With that said, it shouldn't be too hard to play with it if someone had the time to do it. The software pukes down the hall do this all day. I try to stay clear myself.

I looked into it previously by changing the signal from the tone ring on the cam to the ECM, in my opinion it is not worth it due to the lack of timing advance you can run effectively on the piston/injector combination.

That makes sense.

Just another hypothetical question here, to test the theory.

Could you test the tubes Vs stock tubes, with the same injectors and fuel and varying amounts of timing advance, from Zero to whatever something like an edge does. Has anyone tried this to see what the difference was. I'm thinking there would be a bigger decrease in power with zero advance, than with advanced timing?

Also, wouldn't a delay in timing caused by the tubes give you a little more room to advance and still run effectively with the "piston/injector combination"?

Can (or do) any of the electronic boxes change timing due to RPM since it is controlled electronically on the 24V engines? Then it could change for idle and fix the fuel at the top? (make sense or am I lost?)
 
I guess I should correct what I said earlier by saying what I meant to say was 0* advance over stock, so whatever stock is. I have no idea what stock timing on a 24v is.

with the new VPs coming out and ADR and REVO adjustable timing maps, has anyone tried this yet??
 
I have watched a truck run .093 lines and tubes then sold them to a buddie and put the stock ones back in, the next 3 pulls he did horrible, lets just say he lost money.

Your buddy did horrible? I would expect him to.
