What pids did you guys get, mine only has 31, and none of them are helpful like egt or trans temp. Do i need to get the ford enhanced pids. drew techs website seems to be down too :lame2:

You don't need to buy any extra there's a way to do it, I'll find it when I get home to a computer and off my phone If someone hasn't already

i found something, but im not getting egt or boost, but like 58 pids now

Egt is egtra I think and boost is mgp under ford specific

:whs:

EGRTA = EGT's
MGP = Boost

thanks pog and jeff, i was hopeing you would be on to help. just trying different ones to see what they do

No problem!

Back pressure is also one you may want to consider monitoring. It is listed as EP on the DashDAQ and it reads PSI with barometric pressure added in, so actual back pressure is going to be roughly 13-15 psi less than what you see on the gauge.

Just use EP absolute, it has the calculation already done.

EP absolute reads with barometric pressure added in. EP does not, but it reads what the ECM wants to see...not actual back pressure.

I had to do a few different steps like Josh said. but I got like 50-60 now I think

6.4psd916 · Jan 30, 2012

ya, i have eot, ect, egt, boost, frp, bp, and trans temp, anyone have any good custom backgrounds for it?

Should be 49 Ford specific and then what you get with generic OBDII.

6.4psd916 · Jan 30, 2012

it said 56 pids a few minutes ago. thanks for all your help guys. the dashdaq website is down for some reason, so i cant check for updates or download the software for making custom backgrounds

anyone have good mounts, besides the one above the ac vent

What do you meant it reads what the ECM wants it to see?

Desired pressure is what the ECM expects to see in correlation with everything else. Absolute is actual back pressure with barometric pressure added in. Most of the time desired is pretty spot on with absolute - barometric pressure, but they aren't always close.

Erikclaw · Jan 30, 2012

I still don't get "what the ECM expects to see". So it adjusts parameters so it sees what it wants?

Okay, let's say (hypothetically) you are at 2200 RPM, 55 MPH, and 28 psi of boost. If desired back pressure is reading 34 psi, that is what back pressure SHOULD be. Absolute back pressure is what back pressure actually is + barometric pressure. Sometimes desired back pressure and absolute back pressure are in correlation with each other. Sometimes they aren't.

I honestly don't know what better way to explain it. Maybe Dustin can explain it better than me. He and I have discussed this before.
