Inlet Air Temp ?

They have them. Let me find them.

I'm not much help. I think SmithvillD or Buddy were talking about them in another thread. Each gauge has a box, they daisy chain together, datalog, and have a little screen that can read any of the up to 30 modules you can daisy chain together... really nice ...

Can't remember the name, or find the thread.

I would really like a small display screen (like they have for the newer rigs...hint hint) that we could monitor / access the info from GMTD Scan with.

Someone from the Place put a small computer screen where the radio and air control is. They had Autoengenuity running on it IIRC.
 
Buddy and SmithvilleD know what gauges I'm talking about. They have a 3 initial name, like GLF, or something like that. ... Damnit I can't find it.
 
The kiwi fuel monitor won't work well with our truck as it does not account for fuel returned back to the tank, I think it works like the scan gauge which several members have used with limited success.

I looked a some aviation instrumentation web sites for fuel totalizers (emphasis total) that reads fuel to IP/nozzles and fuel returned from IP/nozzles that is the only way to actually know how much fuel is being consumed, 1st one I looked at was $750 :eek: .

I sent a note to them to see if they could build an "economy version" as it does not have to be built to FAA specs, since if it quits we aren't at risk of falling out of the sky :D.

Some of the data logging devices that are on the link you sent by time you outfit with required signal conditioners to convert sensor input to a useable output get a little spendy as well.

Some of the stuff I looked at for "ultra-lite" & "experimental" aircraft instrumentation is expensive but comes in a tailorable option so you can configure what you want to read as a "all in one" unit bringing the cost a little more affordable, that I have also been looking at.
 
If gmtdscantech can be loaded into a palm pilot you'd have it. Simply mount the palm pilot to the dash. That is what I was going to do before I bought my laptop. If I remember correctly ,it had to be loaded in a regular computer and then loaded into the palm pilot or similar handheld device. The same may work for autoenginuity for obd2.

Found it! PLX.

Those are nice!!! Can do 4 Sensors on 1 Display with Alarms, and Recall (do watch the videos).

A bit costly....But considering that I haven't found a Pillar Mount (or any type for that matter) that meets my tastes, and functionabilty....this sure would be a possibility.

I called today and they will be having a Fuel Pressure Module out late June.

Kind of nice to be able to surface mount...there like small tv's or LCD...though they do call them LED's

Anybody Know of anybody else doing gauges like this?

Costly yes, but if you buy one at a time, and look at it as an investment that you'll take from project vehicle to project vehicle perhaps...

They look sweet.
 
As for displaying GMTDScan Tech data, I'd thought just a laptop under the seat running the software, displaying on a small, flipdown LCD screen in the overhead console.

For finding the boost level (in a system that allows some independent adjustment of boost level) that provides max fuel economy for a given steady-state cruise power level, I plan to just compare the PCM's commanded fuel rate.

Obviously this won't give actual fuel flowrates, as the OEM PCM isn't measuring actual fuel flowrate. But it should provide a good indication of more/less fuel flowing. With the VGT turbo setup I'm planning, the controller can adjust target boost independently, within the mechanical limits of the turbo/engine combo.

So the thought would be to find a long, level hwy stretch. Then set boost at one level & note how much fuel rate is required to maintain, say a steady-state 60 mph. Then tweak the VGT/boost controller to 2 psi higher, & when you confirm via boost gauge that's actually happening, see what commanded fuel rate is required to go 60 mph under these conditions. If it takes less fuel, then that's a better setting for fuel economy - & vice versa.

Should be noted, this concept should work to identify the cruise boost setting for best fuel economy - for the specific turbo, I/C, plumbing, etc. you're running during such testing.
 
With the cheap cost of computers, thats really a good idea!

As far as cruise boost economy, wouldn't the lower boost always be more economical?
 
Don't know if max cruise fuel economy would be at lower boost levels? It would vary some with different turbo turbine/comp section combinations.

Tough to know beyond theory without testing.

While diesels can & do run under a range of A/F ratio - they do typically gain efficiency with greater excesses of air. Due to better fuel/air interaction. That's even more important in our low inj pressure, IDI engines where the IDI chamber turbulence is such a big factor in fuel/air mixing/interaction.

With turbine drive pressure being proportional to boost - additional boost is not "free". That's the trade-off determining how much excess air you can afford to supply via the turbo. Rising turbine drive pressures proportionally hurt volumetric efficiency (which is more simply understood as % cylinder fill, or how many lbs of air & fuel got into the cylinder).

So for hwy cruise fuel economy, it takes a given amount of power to maintain 60 mph. Your foot & the PCM are varying the fuel rate to put out the amount of power needed to maintain 60 mph. So you should be able to "see" changes in fuel efficiency under similar hwy cruise conditions as changes in the fuel rate.
 
Yes, the parasitic loss of the turbo costs you energy which means burning fuel to keep boost going, so you dont want more boost than is really needed while cruising. And you dont really need any, since empty cruising only puts in 10-20mm3 which doesnt need boost. 1-2psi is good when cruising.

the manual wastegates will hold the wastegates shut so it cant dump boost while cruising. Thats part of the reason the vacuum system outperforms, as well as the vacuum system anticipates fuel increases rather than reacting to them.
 
I thought that the Banks IQ was saying that it can work with any vehicle....would have to phone Banks to look into it I guess...
