Setting up the WB with out HP tuner pro?

[lamoogle]

I've been reading a lot about setting the WB up to read through the A/C switch and I've got everything wired in. My problem is after I set everything up in the VCM Scanner to read it, I get "unsupported Parameter" in the Table Display when I start scanning. I don't know if I set something up incorrectly or not.

I'm using the LM2 with standard HP Tuners, I have the pid setup like this-

([PID7101]/.33)=7.35

Everything I've found said that was the info I should put in for the LM2 over the other widebands I know that others use ([PID7101]/.5)=10

I'm not sure what I've done wrong, also I've tied into the green/black wire.

PLEAS HELP!!!!

Can someone please help me with this? It's a 06' GTO using the a/c high pressure switch to read the LM2.

It should not be an equals sign. It should be a plus sign. But this may not be your only problem. If you are getting unsupported parameter it means you do not have the PID(s) in your table. For that user defined PID to work you need to be logging AC Pressure Volts which is PID.7101.

I will change that = to a +, but does the math sound correct for the LM2 setup?

As for the PID, I see two PID's for a/c in the "HPT Custom Function, Filter and Trigger Help" box and they are PID.7100, PID.7101. They both say AC Pressure and that's it...

When you say "you do not have the PID(s) in your table", what table are you talking about, are you talking about the "Table Display" box? If thats what you mean, do I need the one I setup for the LM2 and the AC Pressure at the same time in the "Table Display" box?

7100 is pressure, 7101 is volts. you need to add that one to the table display. Anything you want to display on the histos, charts, dashboard, etc needs to be in the table display. So if you want to be able to see AFR error against your MAF table you need to have the following in your table display: MAF Hz, Air Fuel Ratio Commaneded (lo res or hi res), AC Pressure Volts (because you're doing math on this voltage to turn it into AFR. You also need to make sure you define your custom AFR PID as an Air fuel Ratio sensor.

The equation is derived from the range of AFR across the range of volts plus an offset. Search for threads with "deux" in the title by me for the full explanation.

I added the AC Pressure PID.7101 to the Table Display and went to read the car and the WB setup I made went rite to Unsupported parameter when I clicked the start scanning button. I've got to have something wrong in the "Configure User Defined Parameters" box when I set it up.

([PID7101]/.33)=7.35

([PID7101]/.5)=10


PLEAS HELP!!!!

Try this

[PID.7101]/(5/15.04)+7.35

[lamoogle]

I tried that now and the same thing <unsupported parameter>.

[lamoogle]

I've also now have tried just [PID.7101] and the same thing!

post your config file

[lamoogle]

Whats the best way to upload the file? I've never done that, but I have emailed them before.

Lets see if this works

EIO is for pro interface. delete your KR setup.

you have to log pid.7101 in the table display as well as your custom afr pid

[lamoogle]

I show on mine that ac pressure(top left) and the custom LM2 wideband (bottom right) in the Table Display. I did delete the KR and don't know why it was in there.

[Google]

take a screan shot of the custom afr settings window and post it

[lamoogle]

[Google]

see attached.. but use your pid.7101 in place of my pid.2811 or just copy and paste from my other post above.

[MNR-0]

Google is correct

If you are logging anything wideband related the custom PID needs to map to the Air Fuel Ratio

[lamoogle]

It still goes strait to <unsupported parameter>


I have been working on this for 2 weeks and I'm about to give up, I've sent a message to HP tuners and haven't got a reply!
