Anyone have a guide reading WB through AC pressure with 3.0?

[blk00ss]

I'm trying to setup the scanner to read AFR through my AEM Eugo wideband through the AC pressure switch. All of the googling it done leads me back to how to' on the old version of HP tuners. So is there anyone who could walk me through exactl what I need to do in 3.0 to get this to work? Sorry I'm still really new to all of this as well lol

Here are the graphics for setting up...1) Set the commanded AFR and the AC Pressure Channels to the channel table. Use sensors when you can...2) Generate the 2 Math Parameters to Transform the AC Pressure signal to the AEM WB and the AFR Error (can't use pre-configured in this case so you have to re-write the AEM WB equation)..3) Add the AFR Cmd, AEM WB and the AFR err series to the chart ..4) generate a graph (old histogram) to take the AFR err data and log it agains what ever you desire (example is for VE)

Ok trying my best to follow along. Just not sure how you're getting the "commanded AFR" channel onto the channel table? I've got the AC pressure sensor on there. But can not find the commanded AFR channel to add?

Close the log, go into an open Channel spot and right click. Up will come an window. Click ADD Channel and the rest is self explanatory. Use the Help file as well if needed. http://www.hptuners.com/help/vcm-scanner/

This is #2 or 3 on the to-do list. Hopefully I'll have one up Tuesday or Wednesday.

Hope so too. Still haven't got it figured out lol

What's still hanging u up and we'll get it lined out

lol it's not too bad, I'll try to get it up tomorrow. Bad part is I don't have a wideband hooked up that way so it's hard to show screenshots of it actually working

What's still hanging u up and we'll get it lined out

Agreed...

If you can post screenshots/channel list/math parameters or whatever you have we'll get you going

It did. Thanks a ton for the help! I've got it reading now. I've played with the formula trying to get the wideband in the car to match the one on hpt. It seems really close 95% of the time. The other time it's off by as much as .5 points. But only for milliseconds it seems. Here's a video I tried to take with my phone while holding my tablet lol. It's much more clear on the phone than it is on YouTube. But you can pause it and make out what the gauge is reading VS what hpt is showing. Is this acceptable or should I try adjusting the numbers more? I started with 9.3 and this video is with it changed to 9.49

Oh also, you can see how my RPM gauge is reading in hpt. It's only showing .9 for under 1000 rpms, 1 for 1000, 2 for 2000, etc.

How do I get it to read exact numbers. Like 950, 1020, 1057, 2030, etc.

[schpenxel]

Post a log and either a screenshot of the RPM gauge setup or your layout config. Should be something simple

Open Gauge Layout, go to Gauge and change Major Ticks factor to 1, sb 1000 right now.

they really made it difficult.....

How is it anymore difficult than 2.24?

i find it very complicated but im not a tuner just logging for my tuner tried for hours and got no were when i used 2.24 was much easier..i see 3.0 not user friendly

Did you watch the video from above? Pretty much all the steps are the same as in 2.24......pick the sensor pid you are going through (AC or EGR) and inset into the Table then in User Defined, you would have to also "Transform" the analog signal and we did that through User Defined by doing the exact same equation. And of course as this falls outside the normal wideband/Error handling we needed to generate an error user defined as well exactly as we do now.

Did this ever get posted? I'm not finding it through serach.

[schpenxel]

I haven't gotten to this one yet. Ed put together a video that should help quite a bit

I saw the video. I just follow written instructions better. As a new tuner (like less than a week old) I've come to appreciate your expertise quickly. Your how-to's are spot on. I'll keep a lookout in the future. Was wanting to read up before my wide band setup arrives.
