I have three ISSPRO EV2 gauges, and each one is a different generation - they were purchased at different times over the last 3 years. The driver-side Pyro is one of the early units with an LED alarm that's programmed in. The passenger-side Pyro is identical to the other one, but it has a different part number. My latest gauge is a 0-60 PSI boost gauge (my wastegate opens at 34-35 PSI). I installed a switch on this gauge for the two sensors already in the truck, allowing me to use the same gauge to check fuel pressure when I need to. Some think I went over the top on that one and some sit quietly, mumbling "were it not for the train wreck appeal, I'd stop clicking Tugly's stuff", but scotttahoe likes the process - because he gets my old 0-40 PSI boost gauge (with new sensor and wiring) at reduced cost.

With my latest purchase, I downloaded the newest version of the ISSPRO EV2 Warning Light Programmer - it can program how the gauge behaves, the alarm limit, and the backlight. Installing the updated software is where the thread title comes in - there were many kinks in the process. That was a real adventure going from one version to another. It was in no way automatic, and I'm glad I have computer cognizance to corral the kinks. A fresh install would likely go better, so don't let my failure as a train engineer frighten you away.

After programming all three gauges with the new software, the new gauge works perfectly, but the pyros - well... that's another matter. They sit there lazily while the truck is warming up, then for no apparent reason - one will show the current temp and stop, then the next one will show the current temp and stop. Since they never show the current EGT at the same time, the needles point in different directions like the eyes on a chameleon. They do this at regular timing intervals (implying a built-in schedule, not random), so this was my clue to figuring out what went wrong.

The new software has a list of files with programming criteria for each gauge. Simplifying this: I call up the pyro, and the software says to the gauge:

1. 1250 (Your alarm is 1250 degrees)
2. 270 (You have a 270 degree sweep)
3. 250 (Scan rate 0-250 with 250 being the fastest sampling of the temperature)

The third-generation software added some cool features for new gauges (with a relay to control an external device), but one of the feature commands is in the middle of that list. The new software says to the gauge:

1. 1250 (Your alarm is 1250 degrees)
2. 270 (You have a 270 degree sweep)
3. 0 (The default alarm relay is off)
4. 250 (Scan rate 0-250 with 250 being the fastest sampling of the temperature)

Uh... number 3 instruction just changed to 0, meaning it will check the temperature once in a while - I estimate about once every 25 seconds. The gauge is an idiot, it just gets numbers in sequence and can't know something is out of order. That's about a useless EGT gauge, but it would make a great transmission temperature gauge.

The above is oversimplified, but that's the gist of it. I need to check if I downloaded the wrong version of the software, but it works on my newest gauge. As it stands, I have to hack the programming for my Pyros - but it will be fixed. I also have to hack the programming for the gauge that scotttahoe will receive - I want to customize that gauge for his needs.

 

Contact Isspro... I have had a couple customers in the last few months that had issues with the programers. Isspro found a bug in the programing and I believe its fixed now.

 

Thanks Rich, If you need to hang onto the gauge for a while till you have everything dialed thats fine. I don't want to take something and leave you hanging.

 

I'll have this squared away 15 minutes after I sit down to start - now I just need 15 minutes without something else that needs to be done first.


Joe - I can call ISSPRO to see if they have firmware to change the order my new gauge (or my old gauges) accepts instructions. As it is now, the old gauges cannot use the new stuff, and the new gauges can't use the old stuff. There is an easy (but messy) work-around. The gauge shows a version letter on it, which seems to coincide with the software versions available. I would be surprised if I could run multiple versions on one computer, one version overrides the other in the computer configuration. The messy work-around is the quickest and easiest solution.


Scott - my new gauge is all set, yours will be ready by this weekend at the latest. Do you have a boost number in mind where you'd like the fireworks to start? If I had stock sticks and a tuner with the red line mod, I'd want 27 PSI - that's about when the SES fires on these trucks. Think of it as an alert to let you know when you thumb your nose at the Ford engineers.

 

Rich, My truck is pretty much all stock. So I think 27psi is best although i'm only getting 12 to 14 psi. I have really bad up pipes and need to replace but wanting to convert it to 99.5 from an E99.

 

You don't have to have an alarm light... but I had mine set to where I limited out, so I'd know to look if the light didn't flash when I got on it. This made it so I always knew if I reached peak boost without having to look over.

 

I struggled with my new Fuel Pressure & Oil Temp gauges as well, couldn't get the programming to take. Just kept at it and finally after the 5th time it took. I still get an error message on the software during the programming.....it keeps looking for a file that isn't there. I haven't had the time to call or e-mail ISSPRO since we've been overwhelmed with finishing harvest before the big deep freeze.......

 

Ah... I know this one. If you go into the folders provided by the software, there is a folder named "4743I Spreadsheet Data". Copy that folder to the raw C: drive, and the software will locate it there. Once you're on the list of gauges to choose from, there will be identically named gauges for the Pyro. The Pyros further down the list are the ones with the alarms, and the upper ones have no alarm feature. Just pick the one with the range that matches your gauge.

Deep freeze: We've had a freak warm climate this year, with not even so much as frost since early spring. Today's high was cooler than our coldest night in a long time, and I had to do slide pins in freezing weather tonight. There are a few orchards with fruit still on the trees (they need the cold nights to ripen the fruit), but it's going to be 16 degrees tonight. Maybe there's a market for "ice" apple juice like there is for ice wine.

 

Thanks Rich, I just need to get the time to mess with it......right now we're running around getting everything set for the cold weather. I'm glad I've go the oil temp & fuel pressure gauges installed for the single digit temps this week.

 

Has anyone tried adjusting the Data Rate on the fuel pressure gauge? Looks like the default setting is 1. I'm trying to smooth out an erratic needle at idle.

Data rate? You mean the Hysteresis? I had my Hysteresis messed up one time because I accidentally used the wrong version of the software for my generation of EV2 (so much for updates). The new EV2s use one version, and the legacy EV2s use a different version - and they are not compatible with each other. Really forward (not backward in this case) thinking there.

Both versions are available on the ISSPRO website, I have 2 generations of gauges and it messes with my mind. The "classic" version screen is in woodnthings's document you linked to. I forgot how to distinguish the two gauge versions, I need to review my notes when I have time.

Changing the scan rate can leave long moments of a frozen needle - or make the needle twitchy. The Hysteresis can smooth a twitchy needle while keeping the data "live".

 

Sorry, I said data rate prior to looking at the software. Used the wrong term.

I adjusted the "weight" setting to get a smoother needle movement. The Hysteresis seemed to change the needle movement "minimum requirement" value.

I guess you can do it either way as long as you don't make too drastic of a change. It's all good......

 

just purchases a new ISSPRO fuel pressure gauge for our F-250, the old one finally died. But there is an update - if you have the software they recommend the fuel pressure setting to be changed to:

sensor scan rate = 100
weight = .1

 

The old one finally died? How old was it?

 

Watch out! The old software works with the old gauges, and the new software works with the new gauges. The software update is a free download. I looked into how I could get one or the other to do both - but the engineers took a nap at the reverse-compatible meeting.
