I have been trying to log my wideband afr sensor on my 2007 Chevy Cobalt 2.2. I created a custom PID to read wideband voltage through my AC Pressure sensor and added it into the chart view in VCM scanner. When I go to do a log, everything seems to work fine.
Here is my problem. When I open VCM scanner and go to table view, my wideband PID is there in the EIO inputs, but when I open a log, the input disappears. I can still see the values and the graph on chart view, but when I send the log to my tuner, the same wideband input will disappear and he cannot see the values for the wideband sensor at all. We are using the exact same configuration file. Please help. Thank you in advance.

are you opening an old log and trying to view it?? if so, you only log whats on the table at the time its logged. try to log it again with that config and see if it comes up this time. other than that, i dont know. hope you get it figured out.

Thats the exact same config that i logged with. Thats why this is so confusing. I just wanna finish tuning my car! Haha

let me get this right, does the ac pressure pid disappear as well?? you shouldnt be able to see eio outputs with standard. at least not when you are logging, because there is no eio input port for standard hpt. i think thats part of the problem. but the ac pressure pid shouldnt disappear

i know he can see my ac pressure voltages but when he tried to enter in my function to see the values as afr instead of voltage, it gives him nothing. at least that is the way he is explaining it to me

he needs to set it up as a custom pid and it should work. if thats what hes already trying to do, then theres just something wrong with the pid.

i do see one thing wrong. i know that hpt says to use the generic sensors rather than pids, but for our 4 cyl cars, sensors are not always the best to use, because they sometimes get averaged for 8 cylinders or 2 banks of cylinders, but we only have 1 bank. injector duty cycle is a good example of this. the idc from the generic pid is half of what it should be because its averaging between our 4 cylinders and 4 imaginary cylinders. thats why youll see people on here saying that their gms2 only hits 50% idc at redline, because they are logging the generic sensor driven idc calculator when they really need to make their own custom pid using pids and not sensors

with that said, try leaving the dropdown list on the custom pid for a sensor to "none" and just let your custom equation run the pid. that may be whats screwing you up.

i have my wideband setup calling on "none" for the sensor and it works well with only a custom equation.

edit: and also put the custom wideband pid you made into your table and not the eio output table

It shows up on the eio inputs by itself. I will try using just the pid without the sensor to see if that works. Thanks for the tip

So did you ever get it figured out?

i got a few tips from southalcobalt, he was a big help

i have yet to try it with my tuner though because i work when he tunes on most days.

ill know for sure tomorrow

Let me know! I'm planning on using the same method. Don't want to be left clueless if the same things happens.

did you and your tuner get this figured out?

For some reason or another he still cant see the wideband chart but he can see my ac pressure voltage so hes pretty much just going off of that and narrowband for now. He was saying something about it might be a problem because he has a beta version of hptuners. He said he emailed them but idk if he ever got it figured out. My car is running pretty good now though so im not too worried about it i guess.

and the one youre logging with does not have beta? you can download it on hptuners website if its still on your mind. glad to see your getting good results regardless

Maybe i will try looking for it. I just have the latest on the home page you can download.

James is tuning him.

Just throwing that out there...

Makes no difference who is tuning my car. Keep your unwanted opinions out of my thread.

The new beta is not available, you have to request it. They are adding a lot of ford and dodge vehicles to 2.25 and the scanner has been having some bugs.

^ thats right. i forgot you had to request for the betas. i always just wait to download the latest suite files after all the bugs are worked out. downloading the beta is nice sometimes, but when things dont work right, you cant go back to the most recent non beta from what i hear

My tuner said he even tried going back to 2.24 and it wouldnt read still. Im going to finish my tuning in person but for now what we are doing is working fine.
