What's going on?? Datalogging

[Broncman]

Decided to start this thread for all the techy types out there and to glean good usefull info. Do you currently datalog and what is your setup? What data would you like to see?

Since I am new to diesels, their is a large learning curve for me and I love the tuning part as much as any of it. Here is what I currently have.

Innovate LMA-3 and TC-4. I can log RPM, Boost, up to 5 temps, g's (acceleration etc) and speed/frequency input as well. I allso have several Auber digital display units that can monitor about anything but can not record data.
Currently monitoring both sides of turbo EGT and both manifold halves (cylinders 123, and 456)
I will be using open tip EGT probes as they respond much faster and give a truer reading due to less heat soak. I am currently modding some RTD's for intake temp sensing.

My truck: 78 F350 2wd with 3.73 rear axle and NV4500 trans.
Stock VE pump with stock fuel pin, stock 92 intercooler. I do have a slightly ported exhaust manifold, S300 turbo, 4 inch downpipe and straight exhaust, grid heater delete.

With the above combo, what do you think my EGT's should/will be pre and post turbo?

I hope to be able to pull the grade info from the accelerometer in the meter to show percent of grade for the hills etc as well.

Stay tuned for log charts as I do mods etc.

You got any logs etc, post them up!

I couldn't justify the expense of a full fledged DATA-logging system ($$) so I opted for the ISSPRO Performax system.

IIRC, it can support up to 17 different inputs though some are specific to a particular sensor/probe. They've yet to integrate a tach signal that I know of (they're supposedly working on it).

I've not made the time to work on it lately but it serves my purposes of tuning my mess.

This is from sometime a year or so ago . . . .

Nice! I will look up the ISSPro logger. i was just familiar witht eh Innovate stuff. What kind of probes and pressure sensors were you using?

Details on your truck!!

The individual gauges that you use all connect daisy-chain via a 3-conductor cable back to a single control box (ONLY one needed to support all inputs). Use what ever gauges they offer to suit your needs. NOTE: up to 17 inputs are available.* That set-up offers a Total-Recall feature to see where your peaks went.

But then you can add the DATA-logging gizmo, and it allows you to see live DATA as well as log it. The saved log is viewed via an Excell spread sheet in the format shown above.


* The ISSpro original default spread-sheet has the default (ISSpro) sensor labeling.

Each gauge/sensor as sold by ISSpro plugs into a specific port of the control box. That port ultimately supplies DATA to a specifically labeled column in the spread-sheet. The as sold selection of sensors (by application name) doesn't allow me to monitor all I want. So I called ISSpro (Michele) and confirmed one can put a given pressure sensor here, instead of there (both reading pressure). For example, a 200psig transmission pressure sensor could actually be placed to read turbo drive-pressure instead. I've just got to relabel the spread-sheet column title.

Make sense?

As such, I've gauges and sensors for Trans fluid temp, Fuel pressure, EGT, Boost, as well as a stand-alone 4k tach. I've additional sensors (I didn't want the actual gauges) for Turbo drive-pressure, Primary output, and Secondary output (the boost pressure gauge and it's sensor read boost at the intake log).

A single USB cable connects the system to the small lap-top for DATA-logging sessions (tits-n-tune). Else, just unplug the USB and drive with the four initial gauges.




My mess amounts to a factory original short-block, a ported head, cam, lifters, push-rods, valve-springs, big IC, typical 62/14 S300 over an HT3B, with the other typical stuff. The stock/OEM 12mm VE injection pump (with a custom gov spring) feeds some larger injectors. NON lock-up 46RH transmission. Little stuff here and there, etc.
Last year, it managed 430ish over 1006 (@ 250ish ft elevation). I've made some improvements since. Last year it ran the 1/4th in 12.81 (6400lbs / @ 15' elevation). Gonna do a dyno run tomorrow (@15'elevation) and see what it's good for. Ran an 8.09 in the 8th (6400lbs / @ 250ish ft elevation) last night.

I like the innovate stuff. But what about high boost. Say somebody wanted to check boost that can go as high as 100psi or higher.

I know a friend, Who knows a friend, who needs a decent datalogger. 8 egts, 2 map sensors and thats about it. any recommendations. Cheap...

[Broncman]

To log that high of boost, you can set up one of the innovate channels for 0-5 volts and use any of the pressure sensors that handle that range. Auber instruments have some that would work for that. Innovate SSI-4 wil do 4 channels and their TCI-4 wil do four EGTs. Each one is a hundred bucks.You could daisy chain more than one for any combo.

The Isspro stuff is nice but looks like you have to buy the electronic control module, gages, and data logger.

Auber has a nice meter\controller that wil read about any sensor, give you a display, contact output, alarms, AND a analog output to feed your datalogger for about 75 bucks. Out spears to have the most options for the money.

PLX Devices has a touch screen display meter than will read and display four things at once, but their sensor modules are pricey.

Got everything on line today except the preintercooler temp sensor. Finally took it for a short drive with 2 small hills. Everything is done now except getting a tag and license for the truck then I can hook to something and get some real data!

I am currently logging: RPM, Boost, Exhaust Manifold for cylinders 1,2,3 and 4,5,6, Post Turbo, Intake Manifold temp.

With the 3200 rpm spring I could fuel all the way to about 3100 rpm so I am happy there.

Cylinders 4,5,6 at full throttle and boost run about 100 degrees hotter than the front. not sure why on that one.

Full boost was only for4-5 seconds max since this was a short drive. Max Pre Turbo temp was a little over 1,000 but the highest after turbo reading was 645 !! Sure this would rise with extended periods of boost time such as towing.

Just be warned that if your EGT sensor is after the turbo, it is considerably lower than pre turbo!
