AeroForce definitely can display IAT and IAT2 on my 2008... and much more.

Here is my normal view of gauges:

Okay...so what did you have to buy to display those values on a single gauge only in a car...the unit for $250, the A/F kit for $200 and another $100 for the boost sensor and maybe the 5V power converter they sell? Using the A/F and Boost sensors as your two signal inputs in addition to the OBD parms that are available to be displayed? So I would be looking at around $600?? 2010 like the 2008 with no built in A/F monitoring.

Single Gauge - $249
O2 Wideband kit - $189
3.5 bar MAP sensor - $64.99
Add-a-circuit - $7.50 (optional)
Roush vent gauge pod - $32.99

Worth every penny to keep tabs on vital systems in your car. I did not need the power converter in my application. Yes, A/F and Boost are my two 5VDC analog inputs. If you are tech savvy, you can use Firewire to connect your analog inputs to a SCT X3/X4 device for datalogging A/F and Boost. Also, the WOT Record and Playback feature on the gauge is cool.

Where does the 3.5 bar monitor screw in on your car? I have an VMP Gen2r but don't have my car to see if I have a port somewhere on the blower or engine intake area.

I am going to go with this same setup since my other option was a separate A/F gauge with also a Banks gauge setup. I like the Banks gauge but adding options gets very expensive.

You can "T" in the MAP sensor at the stock fuel rail pressure sensor. I have tubing running from the "T" into the passenger compartment, driver's side under the dash where I mounted the MAP sensor for ease of electrical connection and protection from the environment. I have also seen them mounted in the engine compartment.

Okay....thanks....when get home I'll check it out...seems easier than I thought it would be. Since I am wiring up switches for my VMP HE this is the perfect time to wire it up since I have everything opened up...exhaust removed, seat removed and easy access to everything.

but this is turning into a money pit...my last options for this car!

What is the color of the lcd screen you have on the gauge labelled SVT. It looks like white on blue but I only see blue/black as an option.

The screen color is Cobalt blue. I can invert the color as shown below. You also have the option of ordering custom gauge faces and bezels.

I had the blue/white aeroforce dual gauges in my car and it's wasn't without issues. When it was really hot outside and the interior was warmed up in bright daylight, the display was really hard to read. Now I do have these on the SOS gauge pod. I sold that set and got the black/white gauge set and visibility is much, much better regardless of temperature. I just thought I'd add that. Installed in an a/c vent, you probably wouldn't have that issue.

I ordered everything but the actual gauge since I haven't made up my mind yet and need to see the inside of my dash again since it is a 2010 with that brushed aluminum face. I will be putting it in the left vent.

Here is what bothers me...there is a large thread on this or another site that warns everyone about starting the car with the gauges' OBD unplugged (like if you are using an SCT plugged in instead). Users complained of blown sensors due to no power to the gauge and therefore improper impedence. I don't know if the A/F sensors and intake pressure sensors are still susceptible to this issue but it would be a problem if they are. Are you aware of this or had an issues with blown sensors with your Aeroforce devices. It is basically the ones that use the auxiliary input connections that appeared to have the warnings and issues.

Now I am confused....Cobalt blue?? is that an option because it isn't listed as an option when I look at the site.

It seems the screen color option may be blue/black? Is this the blue gauges listed below with different internal gauge lighting options? (Not the green one of course).

The other issue is what is the real difference between the polished versus the silver anodized bezel??...since it is going in the air vent so it will be one of those options probably.

Installed my gauge and sensors many years ago and never had an issue. I datalog with my X4 a couple of times a year, with and without my analog inputs connected via Firewire.

Just blue. The bezel you see on mine comes with the gauge... it is not custom. It appears to match my interior trim pieces.

Cobalt Blue is the gauge series for the Autometer gauges in the pillar pods in his pic. It has nothing to do with Aeroforce other than to color match his gauges.

Thanks!

Everything ordered.

Hopefully it arrives in a week or two....if by US mail then maybe a year or two !!

Here is my Aeroforce issue....have issues with both Analogue 1 and 2 (OBD2 pids work okay).

Issue 1 - I can't get any boost reading (3.5 bar wired to 12V supply - same power source for the WB controller) - won't even display it on gauge when viewing so I am thinking there may be no voltage present on the input to the gauge? It does not even present it on the screen. Will meter it out I guess. I hoped I would have no problems so of course I buttoned everything up already!

Issue 2 - At 780 rom idle my sensor is reading 10.3-10.4...no even close to where it should be. Rechecked the setup values and they are what the docs said to set it for. I read others had this reading too but no one ever explained what they did that solved their issues. Values rise as I give it gas. Did not yet do a WOT to see what it would read yet but it should be at 14.xx just idling. This is the newer LSU4.9 O2 sensor kit and it says the sensor should not need calibration when first installed.

Got everything installed and spend the last two months with the car on jacks and ramps changing things...new MGW Gen2 with Mobile 1 change - really like it, new VMP tri-HE - wired up option to turn on with just key on and also option to turn off fans at any time, new upper RTR 2012-24 style UCA and new differential bushing, new exhaust from manifolds to rear, fixed driver seat padding issue and restained, added Steeda jacking rails and jacking posts, installed Aeroforce gauge and sensors. Only two issues - muffler sound and of course the Aeroforce....and I sprained my wrist when the drill twisted drilling that &%*^% headpipe for the sensor. That was 2 months ago and wrist is still messed up.

I don't use the sensor for vacuum/boost, but I'm pretty familiar with how the gauges work to enable you to trouble shoot. Aeroforce states the MAP sensor is based on 5 volts. You were given a slope and intercept to program into the gauge. These are just conversion factors to take volts and convert them to a digital reading. The slope and intercept for the 3.5 bar is 14 and -14. So if the map sensor is reading 1 volt, the gauge should display 0. You would multiply volts times the slope and add or subtract the intercept. Since the intercept is negative, you would subtract it. So, (1 x 14) - 14 = 0. If the map sensor reads 0 volts, it should read -14 psi (vacuum). If the map sensor is sending a 2.5 volt signal to the gauge, the slope and intercept should convert it to 21 psi = (2.5 x 14) - 14).

So if you're seeing 10 psi at idle, I suspect you did not enter the intercept as a negative value, so I would double check the values you entered. At idle, you should be seeing engine vacuum which would be negative values. Based on the slope and intercept, the lowest vacuum reading you can see is -14 psi. I say that because the MAP sensor can't read below 0 volts. However, vacuum isn't measured in negative PSI, but IN HG (inches of mercury). You need to apply a conversion factor to the psi value to read vacuum in inhg. Doubling it is close. -14 psi would be 28 inhg. If you're running stock cams, you should probably see something like -10 psi at idle (20 inhg) . You say you see 10 at idle, but is there a negative sign attached to it?

Here are the instructions I'm using to come up with these values. https://www.aeroforcetech.com/files/3_5_bar_MAP_sensor_kit_instructions.pdf

Almost all engine sensors are based on a 5 volt output, certainly as it applies to Ford, so what I've written above will apply to any sensor you may be trying to troubleshoot. If you entered the slope and intercept as 0 and 0, it should read volts on the gauge.

After rereading your post, I realized issue 2 is your A/F gauge. However, the same slope and intercept info I posted applies to that. I'm sure not all widebands are the same, except for being 5 volts, so you may have to come up with your own values for slope and intercept, although I'm sure that data is probably provided with the gauge.

Sounds like issues with setup, which can be confusing.

Select parameters to view:
*Analog 1
*Analog 2

MAP conversion:
Slope = "014.0"
Intercept = "-14.0"

AFR conversion:
Slope = "002.0"
Intercept = "010.0"
Calibrate your controller/sensor.

If still not reading correctly, make sure your analog inputs are not swapped.
Don't select the Boost PID. You want to view Analog input, which can be sub-titled VACUUM/BOOST in setup. MAP sensor displays PSI only, so you should see -10.X at idle with stock cams.
