drive pressure

one thing larry when you find the tubing that will work, DONT try and bend it yourself unless you are good at that kinda stuff or you will end up crushing the tubing or kinking it
if you dont have acsess to tubing benders bend the tubing around a paint can or something like that so it will not kink

 

[sweetdiesel]

I thought in a different post you said not to use copper tubing , so is copper tubing ok instead of stainless "I'm assuming that is what you were refering to when saying SS"

Using copper tubing might make this a one stop shopping trip

Where did you get the braided hose from?

i think it would be OK,im not sure i get stainless tubing from work so thats what i use

the braided hose..same thing get it from work FREEBIE

now for hooking it up to the EFI, i havent done this YET but you will need a calculated PID selected 0 volt = 0 psi and 5 volt = 100 psi or close to that idea anyway

hooking it into the EGR plug would be nice,it is a 0-5 volt allready
i posted a link to the thread a while back on how to do this,ill see if i can find it

or you could simply run the wires through the firewall and plug it in to the EFI using the orange plugs

this would be a huge bennifit to log it and not just see what your pressure is...so when you get it all figured out, you can show me how

Waiting for KB to reply, he indicated that I could hook to the scan gauges, so, if that turns out to be easy, then hooking to EFI should be a snap.

My egr plug is taped off and just hanging there, Maybe i'll put it to use if I can figure it out.

I think I just found my one stop shopping, thanks Simon

Sounds like your on a role Larry. Keep going and going and going.

Pat was doing some messing around with it but I don't know how far he got or if he got it to work with his EFI. Hopefully he chimes in here!

Just trying to keep up with the Jones, err I mean Kimbles

Curious, how would this actually hook-up to the scan gauge and how would I program the gauge to read the pressure?

you have to find a high temp transducer, with a 5V scale

you have to find a high temp transducer, with a 5V scale

unfortunatly,i dont think a high temps sensor is needed as long as your not plumbing it right on to the side of the exhaust manifold

reason i say this, is mine was definatly frozen today i pulled the truck into the garage and after tinkering with some other things, i pulled off the sensor from the end of the hose and out came some water
started the truck and shot the most disgusting balck sooty water all over under my hood. plug the sensor back in and low and behold it works again

SO.... the moral of the storey is make the tubing exit the manifold in a all upward posistion,mine went down and then up:banghead: or option B live in sunny California

 

[Killerbee]

aaah, true that. OK, I've had the flu, and still do. A bit of a fog here.

Larry, I will find out how the scan gauges will interface. There were some little wiring harnesses that came with the scan gauges. Still have them?

 

[LarryJewell]

I think I kept them, i'll have to look this weekend.

 

[Killerbee]

You will find the inputs on page 3, they use the 2 harnesses

there is a routine that you go through on the gauge itself to calibrate the sensor for scan gauge use. You have to input a slope and an intercept. Don't worry if this means nothing to you, it is just the numbers that relate the linear voltage relationship. ANY 5V sensor can be used, as long as it is linear. we just have to determine the voltage/psi relationship, which is usually supplied by the sensor mfr.

 

[LarryJewell]

Is my unused egr plug a canidate?

 

[Killerbee]

It doesn't have to be unused. You should be able to take the 5V reference signal from any of the sources, MAP, EGR, MAF, Vane Position, etc. Splice and go.

If you have a male harness for an unused plug, all the better, no splicing. But you will only be using the 5V ref signal (usually red I think)

EGR it is then!! I think most people could use that one!

Looking forward to a logged result. Please get a baseline from a stock tune, stock charger. This is essential to compare against future modifications, inlets, tunes, chargers, etc.
