can someone tell me what the byte # is for the AC high pressure sensor in datamaster DA? i'm trying to set up custom data info for my wideband 02 and cant find the byte #, i know it's not 30. any help would be great. thanks

I don't know but, I talked to the datamaster support rep a year ago and he directed me to a 4th gen camaro website. There some guy was having success developing voltage tables through the A/C circuit that translated to W/B ratios. Unfortunately I can't remember what the site was. I guess that makes this reply useless. anyway please post your progress I'd like to know how it turns out.

this may be the guy your talking about, but the byte # is different on my 92 lt1 but the math is all there. i emailed the folks at datamaster about the byte #, just waiting to here back.

i downloaded the the data and it says byte #20 for ac high pressure sensor, but i dont think its right. if i just had the correct byte# for datamaster da i could do this. oh well i'll just wait and see what datamaster says when they answer my email.

thanks for your help

1992 corvette lt1 m6 ac pressure in datamaster da is byte#23. it works great.

How did you find the answer "byte#23"??

According to the datastream definition file it should be #20.
I have a 1992 auto. converted to m6. I don't know if there is a difference between auto and m6. Would you know???

Guitarguy

i figured it had to be between 20-40 i opened a datalog that had my wideband hooked and started at 20 well it didnt take long. works great and it is the same for auto 92.

After I posted my question I tried exactly what you did, and it works great with byte #23.
Too bad you can't export "custom data" that would make it even better.

Thanks for your help..
