Thread: Aeroforce Scan Gauge

I am having a problem with the new gauge. When I turn the car off and on again I have to unplug the OBDII port and plug it back in to get it to come on. Do I have to hook up the Acc Power to it for it to work right? And I noticed my TOrque is really up there is it really that reliable. Cause I am reading like 500 FtLbs No Way.. I know that is wrong my HP seems to be on though. I do like it. I have to get my Pod now to install it right. I am also looking at my knock and it shows like 3 at wide open. Is that right?

Because of the bcm mine has a 5 second delay before starting up. Are you leaving it plugged in long enough from a cold start for it to start up on it's own? Does it shut off after a few seconds when you turn the car off?

I think the torgue reading being off is a know issue.

What year of car? I had to run an accessory power because my 2001 doesn't have a pin on the OBD2 for the gauge to power.

The hp/torque might be off, if you really want to be close then adjust the altitude you have it set on and such.

All stock gp's will read a few degrees of kr from factory. 3 isn't bad but its acceptable when your not modding and making more power than stock.

it is an 01 and the Gauge will turn on then when I shut the car off A few seconds later the Gauge will shut off then when I start the car the gauge 2 lights just blink till I unplug the gauge and plug it back in

weird...My two annunciator lights flash a couple of times when I start my car but then a few seconds later the wlecome screen pops up.

Sounds like you may need the addtional hot wire.

Perhaps shooting Aeroforcetech an email may get you a better answer.

Well they say in the Manual that 96 to 03 most need to have the Extra Power wire for Pontiacs I do not know how true it is but I may write them. Does our car support Oil Pressure I do not think that it does I am going to order 2 other gauges today A manual Boost gauge and an Electric Oil Pressure I think.

No the PCM doesn't have an output for oil pressure that the scan gauge can pick up. My car has an oil pressure guage stock. While I know know the real numbers, I do look at the needle to make sure it's where is supposed to be.

Well I bought 2 more Gauges today ProSport Boost and Oil Preesure and Ordered the 3 Pillar Gauge Pod I can not wait to get them hopefully this week if possible. I want to put them in real bad

If it's an 01 I'm pretty sure you need to hook up a hot wire like I did. I ran it into the cd player wire so the guage will stay on after the car is off.

You have to have the power hooked up to it. You can not rely on the OBD2 port to power the gauge, plain and simple. Once you have the wiring hooked up to an accessory, ie one that turns on when the car is turned on and then powers off when the car is turned off. If you are removing the OBD2 plug when the gauge is active, you run a major risk of messing up the unit.

Make sure you have the power setup and connected to the additional wiring plug provided. And then you have to also REMOVE the red cap from the back of the unit. I left mine on and I got all kinds of security warnings, until I removed it and it functioned normally.

Once you start your car, it will take approx 5-10 seconds for the Gauge to power up, and you will see the two LEDs light up and the prompt on the main screen and then you be taken into the gauge and you can configure it from there.

As for the Analog stuff, there is a bunch of programming you have to do for it and you need to purchase one of Aeroforce's sender units to complete the setup. I personally just a run a seperate OP gauge along with my Boost gauge, Tranny Temp Gauge and my A/F Gauge ontop of the Aeroforce.

I hope that helps.

this is what I am planning on doing as well. I ordered a boost gauge and Oil Pressure from Prosport I can not wait to get them in I ordered the Pillar 3 Gauge pod too. I am not sure what gauges I want to put in to the spot that you have your AF and Trans temp I was thinking Transtemp and Something eles. What is good about monitoring your AF

Did you ever get the wideband sensor installed or does the gauge still go nuts when the car is running?

EDIT: Looks like it's working..I can't tell, but does that AF gauge show any real numbers or is it just a relative range?

Well the A/F LED gauge is basically useless. But the Aeroforce's A/F Millivolts reader is pretty darn spot on. It mirrors the LEDs pretty well, but gives a better number value to what the LEDs try to show. And no I have not gotten a WB A/F yet, though I am diggin' Rick Cobalt WB A/F setup

I am hoping he means what's the value of reading the A/F gauge when it really is not 100% accurate. At least I hope that is what he meant

What I mean is that
Why would the AF be wrong in the first place. What would I have to do to my car Mod wise to Require one of these. What add ons would affect the AF. I figure Cam Injectors things like that. I know that you do not want it to be to rich or too lean.

A/f mV of what? Your Narrowband as in O2's mV verus a WB that reads in a ratio?

I guess *shrugs* I am just going by what the Aeroforce tells me in O2 Millivolts. It is basically a digital read out of the LEDs. It puts a physical number to the nice flashy LEDs

Did I explain that any better??

No, because O2's read in mV, as in say, 960mv may or may not be close to 10.6:1 AFR (example only since accuracy of a NB is questionable, varies from sensor to sensor and changes with temp and age). But if you have no WB hooked up to your A/F gauge how do you know what the air fuel ratio is. Granted the Aeroforce will be accurately reading your narrowband via the PCM. Or are you talking about Commanded AFR, which, unless your tune is spot on, may or may not be the same as your AFR that your A/F gauge with a WB attached would read.

I'm just trying to understand how you hooked up an A/F gauge to your Aeroforce and have it displaying an AFR, unless it is a guessing AFR. Thought maybe you have a shortcut or secret, that you should share.
