Help connecting AEM wb to flashscan

[12sec.5.3]

I feel like a retard but oh well I need help. I have 1 blue wire and 1 white wire that I need to connect to flashscan box. Which plug do I use the 2 pin or 3 pin and also what wire goes to which pin. Sorry for the dumb question but I can't find any documentation on this. Also exactly how do I get the PID set up and ready for logging?

Assuming you have the AEM 30-4100
*WHITE <Analog Output>
Connects to any auxiliary unit that accepts a 0-5 volt input.
*BLUE <Serial Output>
Connects to a RS-232 com port for hyper-terminal data logging.

The white wire goes to EXT.AD+
You may need to run a wire from EXT.AD- to chassis ground.
The blue wire is for serial connection. (V2 only)

How do I know wt EXT.AD+ and EXT.AD- is? I have no diagrams or anything on this.

Thank you! I looked in my efi documentation for this and couldnt find it anywhere.

Do you have V1 or V2...?

If you have V2, turn it over, it has a decal showing the pins.

V1.2

[joecar]

In mr.prick's post, see the first image... this is in the scantool user manual pdf... included with your install of EFILive V7.5 software or from the link posted by mr.prick (his real name).

[joecar]

Which model AEM do you have...?

Does your AEM user manual give you an equation for converting V to AFR...?

[12sec.5.3]

yea it's a 30-4100

[ryans1000]

Also my recent efilive download had no AEM PID's but PLX pids work perfect for that wideband.

[mr.prick]

:doh2:
That's right!
Were'nt you the one that mentioned this a couple of days ago? :hihi:
Tell this guy how to get it going. :grin:

[12sec.5.3]

Well I have the pid created now but just gotta get it working right unless the other one is easier

Yea a month or two ago I was asking the same question. First the student, now the teacher :)

12sec: Yea the plx pids are included with efilive and so its very easy. Also note there is a wideband tutorial included with efilive under the help menu.

The blue wire is for serial connection. (V2 only)Anyone reading this, if you have a V2, then you want the blue wire for serial comms...

I'm not sure if the blue wire is Tx or Rx, but you need to connect it to one of those.

AEM serial users please post some guidance...

[swingtan]

It will be a "TX" signal from the AEM and needs to go to the "RX" pin in the V2. Also, to keep things correct, there should be a "signal ground" wire as well.

30-4100. On V2, Blue wire to AD+ and "Signal ground" to AD-. Do I need to use the white wire as well, or is this not used for V2?

The blue wire is for serial output.

[ blue wire is serial comms output; AD+/AD- are analog inputs ]

You want serial comms connection, see this:

AEM-compatibility (http://forum.efilive.com/showthread.php?15748-AEM-compatibility)
i.e.
blue wire -> V2 RJ12 pin 2
black wire -> V2 RJ12 pin 5

black wire also goes to vehicle/battery ground.
red wire goes to switched/fused vehicle/battery power.

Yep, thats what I did, white wire not used at all (only for analog which just seems to me like a pain in the butt compared to wiring up as serial). Nothing going to ad terminals.

Blue directly to pin 2
black to pin 5 and chassis grounded
red to ign on power

here was my post from the night I did it http://forum.efilive.com/showthread.php?16636-Installing-an-AEM-Wide-Band-02-and-logging-afr&p=148528&viewfull=1#post148528

Hope this helps!

Sorry to dig, but happy I found this. Wondering why AEM isnt listed in the list of WB's. Is using serial output better than analogue or is analogue fine?

[ryans1000]

aem should really be added to the default installation, its probably the 2nd most sold wideband in the U.S. behind innovate.

[ryans1000]

see here on serial vs analog http://forum.efilive.com/showthread.php?17055-is-it-worth-paying-to-upgrade-v1-to-v2-just-for-serial-wideband-input

[johnmaster]

Serial is the way to go. Easy to hook it up once you know what to do. no downsides. Love my aem's, havent used an innovate. Going right now to swap it into my carbed car for dyno tuning tomorrow.

If you have a V2 then you should be using serial comms (ground offsets become irrelevant, and is immune to ignition noise).

[Sixes350]

The only serial port I have on the laptop is for VGA output :(

V2 says it cannot find WBO2 using analogue yet it will display the voltage output fine

EDIT: Ok now I have actually have a good look at the V2 :slaps face: I see that the RJ plug on top of the V2 is for the input of data. Soooo where can I get the cable that will support the RJ plug to serial so I can hook it up properly? Or could it be as simple as cutting up a phone cable?? (simple terms I know but would that work?)

Cheers, Does anyone in Australia make or sell them?

[joecar]

You can make your own, see post #19 above, you will need an RJ12 phone plug.



blue wire -> V2 RJ12 pin 2
black wire -> V2 RJ12 pin 5

black wire also goes to vehicle/battery ground.
red wire goes to switched/fused vehicle/battery power.

[Sixes350]

Made my own today by chopping up a 6 pin phone cable. Works perfect. A little bit of a tidy up and the cable will be spot on.

Is there a way to log 2 AFR's? I have 2 AEM gauges (one for each exhaust) or is logging data from one side only required??
