MPVI2 (and 2+) prolink and AEM CAN bus

[Cranked Automotive]

Can’t wait for this to work!

Old thread bump. Is anyone else still having this issue? I have a 30-0300 flashed gauge with a mpvi2+ with pro features/prolink wired to the canbus correctly. I'm not sure it detects it when polling for additional parameters, but it will not log in the scanner. Running the latest Beta version.

-0300 flashed to what? If it's flashed to the -0334 type firmware then it doesn't get wired to the Prolink's CAN, it goes to the vehicle's CAN. They are different flavors. The AEMnet CAN in the original -0300 firmware was the type that spoke the same language as the Prolink's CAN.

Apologies, I should have clarified. I had an -0334 type that dr.mike flashed back to -0300 for me as I wanted to be able to use with my pro link. However with the wires added and correctly connected to the pro link adding the channels and polling for parameters with it connected doesn't log any data.

has this been fixed? with the MVP3

Has anyone gotten this to work properly yet as mine in vcm always reads a lambda of 1; the wideband I am using is the aem 30-0310.

Hi Keith,
Would you have the the pinout diagram for the Prolink+?

Old thread but I'm having an issue with this myself. I have a AEM 30-0310 and I am trying to log/display AFR on my scanner using the MPVI3 with the ProLink+. I have connected the AEMNet CAN high wire (black/white) to the ProLink CAN high wire (orange) and the AEMnet CAN low wire (green/white) to the ProLink CAN low wire (yellow). I repolled the scanner, added the AEM X series UEGO WB EQ ratio 1 PID. However, when I start scanning, nothing populates in the scanner. Thoughts? TIA.

I'm not sure if this matters, but my swap is an 84 C10 - 2017 GEN V L86/8L90 with a E92/T87 using a Speartech wiring harness an running a 2015 Corvette OS.

I'm having the same issue as well. It's not detecting the prolink as a obd controller. Tried the aem pid in the mpvi3 options and still not detecting on scanner. Are you able to see the analog signal?

The analog signal works great.

Any luck?

Keith - has this been fixed? I added the AEM PID but nothing is showing up when I try to log.

Ok, I've been told this is a bug in the current release firmware on the MPVI2+.

We hope to have the fix in the public firmware, later next week.

If you would like access to this firmware early, please email support regarding this bug and we can get you access.

Thanks.

HartRod I have been having the same exact issue. Created an account just to comment on this. Submitted a ticket on it #432677 lol

I have an 03 C5Z with the AEM 30-0300, MPVI3, Prolink+, etc etc same hardware as you

Same outcome aswell. Canbus wires connected correctly, but when I go to start a scan in vcmscanner it doesn't populate any information on the channel

Hopefully we hear back something soon this is disappointing. If you find a solution please let me know, and if I do I will let you know.

Brandn - I added a 120 OHM resistor in parallel with the CANBUS connections on the ProLink+, used the AEM WB #1 PID, repolled and now it is logging the AFR correctly. Hopefully this helps.

Oh man that's great news HartRod. Out of curiosity, what 120 OHM resistor did you use? I'd love to just copy your setup so I don't have to do it twice lol

I just ordered some off of Amazon. PM me your address and I can mail you a couple.

Man you're awesome brother. PM'd

Did you get it connected and reading AFR? Have you got it to display lambda?
