Aeroforce Scan Gauge

Does anyone know how to install the fuel pressure sensor kit into this thing im getting aggtivated with it. i have one set of instructions and their website says another. There instructions say 5volt and mine say 12 volt. iv got a few pics of this ****ty puzzle if anyone can help me id be greatful. Here are some pics of what came in my kit

PCM's operate from their inputs on 0 to 5vdc. This is done so that while starting and the alternator is recovering the loss from starting( dropping from say 13v to say 11.5v ) it doesn't cause any input issues to the PCM.
The way I understand it is to wire your reg to a "switched 12vdc" and install the resistor inline to the gauge.
The regulator should vary the output to the gauge from the 0.5vdc to 4.5vdc with the sensor inline to prevent a 12vdc feedback if you disconnect from the OBDII port.

You know after studying the confusing install diagram I think that the output from the regulator to the sensor is the 5vdc. The reg is wired to the switched 12vdc then sends 5vdc to the sensor. The output of the sensor will vary 0.5 to 4.5vdc and this goes to the gauge with the resistor inline/series.
You should be able to hook the reg up to 12vdc and see a 5vdc output which would then be wired to the sensor.(green from reg to red on sensor)
Sorry I should have studied it about 30secs longer before I posted the first time.

i see what your saying but the diagram doesnt show 5 volt coming out of the blue heat shrink wrapped thing anywhere. and if i hook 12volt to the 5 volt sensor then its fried on contact. it makes absolutely no sense to me at all im bout to say screw it and sell it all

The green wire on the blue thing should be 5 volts out. That is the regulator they sell right? Ill buy it.

Tncoalroller88 · Jun 2, 2013

to tell u the truth i dont know if its the one they sell or if it just comes with the kit now or what.. but it states on the instructions everything going in and going out is 12 volt , when i thought it was supposed to be 12v in and 5 out. i thought the reg was supposed to be sold seperate cuz i didnt buy one the blue shrink wrapped thing was int the box

and iv emailed scangauge bout this if they dont get back with solid answers asap im selling this hunk of crap and never using their mismatched hodge podge crap again

I'm in for the resolution! I'm wanting this setup as well so I can get rid of my current Fp guage and just have 3 gauges instead of four....

Have you hooked the blue thing up and checked the output. May very well be 5 volts.

I'd be willing to bet its a typo on the schematic. That green wire labeled 12v is probably supposed to be 5v. Plug it up and see like 4.0sahara suggested. I just ordered mine from areoforce so I can let you know in a week or so.

im gonna have the thing tested tomorrow and see but i dunno if its a typo or not.. why would they sell the 5 volt converter seperate if it actually comes with the kit. i really am not a fan of aeroforce at all because of this. i mean come on put all the **** needed in a box and ship it to the customer with the correct directions how hard is that. people spend 300 plus bucks for this crap and they aint even got a guy that checks their **** bag schematics come on now what a crock. people complain bout glow shift pssshhh least their **** comes in one box with a detailed set of instrictions aeroforce is to cheap to even label their sensor box with a photo. what horse ****.... rant over

I didn't use a regulator, I tapped into a 5 volt reference line (I used the MAP sensor). Works perfect.

Tncoalroller88 · Jun 3, 2013

OK so I figured it out finally with the help of some guys on FTE.. The sensor kit I got is the revised version. And it actually used 12 volt and everything is included with the kit... Now that I got it working can someone tell me how they set it up to read correctly ? Also I put my little resistor In the beginning of the white wire that goes to the scan gauge is this right?
