Just purchased an nGauge for my 2010. Had the SCT 2, since 2010, time to update.

I'm looking to set up the screen for monitoring 6 PIDs at a time. What are your favorite/most useful to monitor?

Also, what RPM values, do you use for the shift light function?

Thanks !

I would monitor Ambient temp or IAT1, IAT2, Engine Coolant Temp, Battery Voltage, Spark, Knock Retard, AFR (if wideband), Boost (if MAP sensor).

I don't have a wideband, or a MAP sensor. Can a generic MAP sensor be bought? I was thinking ECT as a good one, as well. Battery voltage, most definitely!

If you want to see boost you need either a Boost box or ZT2 setup. Both are expensive, but well worth it to log boost just to see problems you may not have realized you had. lol
Honestly, most of the data will drive you nuts. I kinda wish I didnt have an ngauge in my car because it causes me to obsess over data I cannot do anything about.
Watch out going down that rabbit hole. lol

Yea I just watch ECT, iat/iat2, volts, spark, ect on mine. Use it for uploading tunes, check DTCs if needed, RPMs I have set to match my OEM Shift light. I also have separate gauges for boost, fuel, afr as well.

AFR, Boost/vacuum, Ambient Air Temp, IAT, Fuel Pump Duty Cycle, Coolant Temp.

This is using in combo with a ZT2. Pricey for sure but I didn't want "unknowns" when dealing with the tuning on this beast. Lund highly recommended this setup.

Have the battery voltage monitored on a scale within the nGauge and will alarm if below a certain level.

Don't have RPM values setup for shifts @ this point.

I really like having these particular PIDS being displayed. Hopefully gives me a chance of catching something before things get really bad.

Cheers,
Ray

I also have a 2010, so hopefully I can help. The IAT1 and IAT2 are not able to be read by the nGauge itself. if you have a ZT-2, it can read basically anything, but requires the additional sensors and wiring. For whatever reason (probably the bastard 2010 year model) A bunch of the PIDs can't be read.

For my nGauge, I monitor Voltage, Manifold pressure, Spark and AFR.

It works really well for what I need it for. I did purchase the additional 3 (or 5, I don't remember now) bar pressure sensor for the manifold pressure, as it can read vacuum and pressure (easy to monitor if there is pressure loss somewhere). I can honestly say that monitoring voltage saved my ass. The car was fine for about a year, but then I noticed when the coolant got up to temperature, my voltage would drop... Complete sidebar here: You can set the parameters for the displayed numbers being white, yellow or red, and can also use things like voltage to trigger an automatic shut down and wake up of the nGauge. After about a week of driving, I recognized that no matter what, my voltage while running was in the 13.5-14.2 range, so i made my yellow zone for voltage 13.0-13.5 and red <13.0. My nGauge shut off is 12.3ish /end sidebar. So my voltage would drop to 12.8 to 13.2, and likewise fluctuate display colors from yellow to red. Concerning. I decided to idle my car -after a spirited drive- in the garage for a bit to see what would happen. It wasn't even 3 minutes before the car overheated. I knew to look for something electrical, and the only thing that is electrical in the cooling system is the radiator fan, which I had suspected of going out anyway. After the car cooled, I pulled out the radiator cooling shroud/fan assembly and sure enough:
Burned connector.jpg

It turns out the resistor in the fan relay on the shroud itself had pooped out, and then burned out the harness connector. I ordered a new 2013-14 GT500 fan shroud assembly from Tasca and hoped to god the harness on the car itself wasn't shot. I did the install this winter, and it is now May. Many MANY spirited miles of driving later, and I can say for 100% that the car harness is good to go, and that everything is up to snuff.

I'm not saying I couldn't have figured this out without the nGauge, but with the voltage warning I knew the overheating issue was fundamentally related to something in the electrical system and I wasn't wasting my time trying to chase down the multitude of possibilities for my car overheating.

On a related note to the nGauge... If someone has an idea for monitoring actual IAT2 that does not involve drilling a hole in the lower manifold, I'm all ears.

Sorry for the diatribe.

TL;DR nGauge is a good tool.

Einehund, great reply thanks! Unbelievable that IAT cannot be read! That's one of the MAIN reasons I wanted this gauge! Can IATs be datalogged, and just not displayed? I know the ECU pulls timing if the intake temps get too hot, so how does it monitor these temps? I followed discussions about this gauge for a while now, and I never knew or heard mention of 2010 issues

I will monitor battery voltage. I would monitor oil temps, if I could as well. Great story about your fan!

I have a 2010 also with an Ngauge. You can display both IAT1 and/or IAT2. I monitor IAT2. When you set up the Ngauge to display gauges, you have to choose model year 2009 and older. I know it doesn't make sense but it works. I saw this on the FordGT500 forum a month or so ago. I may be wrong on the year but I know you don't choose 2010. Try a search on that forum and it will come up.

Ok I will check that out. Thanks for the info on selecting the older model year, in the initial set up.

I emailed Lund about this. This is what they said back, hopefully this will help other people with issues. For a 2010 they said:

"2008 FORD GAS UP is the model you choose. The other one that you would not use is the FORD_GAS_PRE_2008.ng model . See pic."

Not knowing the problem I was having periodical problems going into boost and having the car pull power

that was about a year and a half ago, and this January the problem got very severe. What was happening was that my intercooler pump was failing intermittently and I thought it might have been the tune

Not until one day I was on the interstate and I got coolant spray on my windshield and I realize once I got home that my inter coolant tank got so hot that it sprayed out coolant from the car.

I now have an Ngauge that shows me my IAT2’s and the intercooler pump has been replaced with a better model. If I had the proper gauges two years ago I would’ve known immediately what the problem was
