need some help with histograms

[vetteman3]

Hey guys - My first post here!! First let me say Thanks Much to all you guys who take the time to help out us 'newbees', I have learned much from many hours of reading on this Forum. Ok - I'm an old guy who has been playing with cars for many years and done much tuning but new to computer tuning, and not terribly computer savy, so... So far I have managed to get the VE table pretty well set and made some changes to the timing table and I want to tune the MAF next. My fuel trims have been around -14. The car is a '01 Vette with a Magnacharger and a 220/226 cam. I have a LM1 wide band hooked up and offset adjusted.
Two problems -- I show the A/F ratio in the bottom of the Table, but the graph and wide band histograms show nothing. I have looked over the 'insert' selections and don't see "wide band" there - What am I missing to get the Wide Band Histogram working??
The other problem is the MAF histogram. I have inserted "Mass Air Flow" to the Table, but the histogram comes up with 'histogram not supported' -- What am I missing on this one??
Thanks in Advance

If you have the EIO version, you need to insert your wideband PID in the EIO section of the table. See pic below:

Thanks for the response. I already have "custom lm1" set there with my offset formula and I can read the A/F ratio there, but not on the graph. So I inserted "wideband LM1" from the insert list like you said and that shows on the graph, but without the correction its about 2.0 off. How can I get my user configured setup to show on the graph??
I also need help configuring the "maf hz" histogram. I have selected 'configure histograms on #8, and got MAF airflow vs output freq, units in % on the X axis. Do I need to put something on the Y axis??

I just use the "generic" WBo2 "sensor". That way it works with anything defined as a "Wideband o2".

Just make sure you don't have multiple items on the PID display defined as a "Sensor" as Wideband o2

you have to log the MAF in hertz.

Still no luck!!
On the problem of displaying user configured WB A/F ratio on the graph -- The only way I can get A/F ratio on the graph is to select click on EIO input 1 and select Wide Band O2. But because of the offset voltage problem, the readout about 2.0 off from that displayed on the LM1. So then I delete that, go through the same procedure and instead of selecting Wide Band O2, select 'user defined', and then insert my offset formula. I can then read my actual A/F ratio on the Table view but not on the graph, which is where I need it for WOT tuning. Am I missing a step??
On the problem of configuring the MAF HZ histogram -- I have inserted the PID Air Fuel Ratio Error, and the PID Wide Band O2 into the Table. But when I start scanning, the Air Fuel Ratio Error lable grays out, and the wide band o2 lable just shows 0.00. Then when I go to histogram #8, it says 'unsupported'. What's up with this??

I got it fixed!!! And the problem wasn't with HP tuners program, it was the LM1 set-up. I had not changed the voltage output for analog 2 to 0-5v. I played with this when I first got the lm1, but it was still set on the default 1-2v. Now all is well and I'm off to go tuning!!
