I’m trying to get my AEM 30-0300x to connect to hptuners MPVI pro. I’ve always used the 4110 but it gave it up and I cannot for the life of me get this new one to read anything other than 1.23 lambda in the scanner using the predefined in hptuners. I’ve got it wired exactly as I did with the 4110. I have the solid white wire ran to the number 1 terminal on the mpvi pro and the number 5 pin grounded straight to the battery. The 30-0300x has several more wires than the 4110 for the canbus since I’m plugging straight into the mpvi shouldn’t it wire the same way. What am I I missing?

Are you sure you are using the correct output wire on the WB and the correct input on the Prolink?

Honestly I’m not 100 percent sure what the pro link actually is. I just have the green connector that plugs directly into the mpvi pro. I had the white wire ran to pin 1 and a solid ground ran from pin 5 on the interface to the ground on the battery. I emailed AEM and they told me the brown wire on the wideband needed to be grounded to the cable and that I didn’t need the ground to the battery. I left the ground on pin 5 and ran the brown wire from the wideband to pin 6 and it seems to be working and matching the display vs the laptop using the predefined in Hptuners under serial now.

Sorry I didn't realize you are using the MPVI1, disregard the prolink comment.

Vandyke, when you had your 4110 gauge, where did you connect the wires in the green block that goes into the side of the HP Tuner box? I have a MVPI Pro, its not the MVP2..
I have a 99 Z28 and there is a white wire and the blue wire yet to be hooked up. The Install Instructions for the 4110 says the white wire is 0.5 volts Output and the blue wire is Serial Output. Red wire 12 volts power, and the black to chassis ground. The red and the black wires I've already hooked up.

thanks for your help.

Sorry I missed this. The white wire goes to number 1 on the green connector and run a ground from pin 5-6 straight to the battery. Then do a transform in Hptuners and it’ll give you the predetermined wideband option for the 4110. The 0300 was in there as well.

thanks for info, I really mean it, but just to make sure I understand, on the green connector, pin 5 or 6 goes to ground or both 5 and 6 goes to ground?

If you have an ohm meter, you can check to see if 5&6 are connected together inside the mpvi1. My assumption is they are. I’ve never checked.

But yeah, that’s the difference between the two AEM WB’s. Need to ground the brown wire on the one you have.

You only need to ground one of them, doesn't matter if its 5 or 6, reason for 2 grounds on the MPVI pro is so you can monitor mutlt devices I have both an WB and I log FP with a stock chevy FP sensor, works great.

thanks a bunch, one more question when you can, no hurry, got the trans out to be fixed. So the blue wire from the 4110 goes to nothing?

jaydubb

I had that happen to me. It turned out to be a defective gauge. I contacted AEM and got it replaced.

VandykeT/A

Yes blue wire goes to nothing.

Yeah the blue wire is for serial output, mostly used for sending signals to a PC through RS232 protocol, there are APP's out there that can use it, but I have no experience with any of them.
I know the guy from Goat Rope Garage had a You Tube tutorial on it a while back.

thanks fellows for the help, that squares away that problem, learn from my mistakes, be sure you have the TC fully seated in your transmission before reinstalling the trans and starting the engine. ***** up everything so the trans goes back to my 4L60E guru and the TC goes to CD to get flushed out and inspected. Stabbed many TC's in the past but learned that if I'm not sure, do it over again.
