AEM X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge

[Blacky]

The EFILive software and firmware has been modified to work with the AEM OBDII interface. It's being tested now and it should be available in the next beta update which is due out next week.
The initial release will require the AEM to be selected as the "TCM" controller so you won't be able to log ECM, TCM and AEM simultaneously, you'll only be able to do ECM+AEM for now.



The AEM shows up as GPM (Glow Plug Module) because it defaults to CAN ID $7E6 which is the glow plug module in the GM-LAN configuration.

Cool

Will this allow both LS1 and the aem to be logged simultaneously or only can based controllers?

Only CAN controllers.

so was the firmware modified to work with efilive or is it using the standard firmware and efi is working with that?

Modifications were required to both the V8 software and the FlashScan/AutoCal firmware. The updated software will be available for testing sometime this week on our beta forum here: https://forum.efilive.com/forumdispl...-Beta-Software

Awesome! The workaround of being able to log the WBO2 instead of a TCM is a good choice, the likelihood of having the use the WBO2+TCM simultaneously is small.

Did Dr. Mike make any changes to the 30-0333 firmware to work with EFILive? If not, I have one installed now so I can test once the beta is released.

On the engine dyno we want to see fastest wideband response (engine spins up very quickly on engine dyno), and since transmission/TCM is not present, ECM+WB makes a lot of sense.

Thanks: dr.mike, Blacky.


I'll see if Martin @ CPR Engines has dyno time available soon, this will be fun.

Martin, if you're reading this, this is just what we need for E38/E92 tuning...!!!

So this should technically mean that if you have 2 or more of these bad boys all daisy chained up we can log multiple sensors yeah?

According to the latest pdf doc from AEM on these they allow you to change the address for each controller. Which would make sense on a CAN based network. Can't have multiple sensors reporting with the same hardware address.

The available settings under the 'obd2' menu are:
This is the unique address the gauge should be set to for scanners to be able to accurately detect O2
readings. The actual hex address used will change depending on the 'bitS' option (below.) The default
value is ECU #6 and if using another 30-0333 the second gauge should be set to ECU #7.

ECU # 11-bit 29-bit
1 0x7E1 0x14F1
2 0x7E2 0x18F1
3 0x7E3 0x1CF1
4 0x7E4 0x20F1
5 0x7E5 0x24F1
6 (default) 0x7E6 0x28F1
7 0x7E7 0x2CF1

This is the hexadecimal value for the PID that the gauge should emulate. The default value should be
listed as O2 #1 and if a second gauge is used then O2 #2 should be selected. If your vehicle is equipped
with OEM widebands and the factory powertrain ECU already outputs some of the PIDs in the following
table then you will need to select a different PID.
Listed below are the available options.

O2 # Location PID
1 (default) Bank 1 Sensor 1 0x24
2 Bank 1 Sensor 2 0x25
3 Bank 2 Sensor 1 0x26
4 Bank 2 Sensor 2 0x27
5 Bank 3 Sensor 1 0x28
6 Bank 3 Sensor 2 0x29
7 Bank 4 Sensor 1 0x2A
8 Bank 4 Sensor 2 0x2B
This is the size of the CAN bus message identifier used. The available values are 11 and 29 with the
default value being 11. Most vehicles will have an 11 bit identifier.
This is the bitrate of the CAN bus. The available values are: 250 and 500 kbps. The default value is 500
and is correct for most vehicles.

Now, with all that info I reakon i could get the ALM/Ecotrons working too. As they allow you to program a user configurable can output.

TC,

Thanks for the info.
