ls1a error report maf HZ

[Tool Guy]

I am getting an error report (out of range) when I try to log MAF raw frequency GM.MAFFREQ2. Is this not supported?

[joecar]

GM.MAFFREQ2 is for GenIV (E38, E67).

[Tool Guy]

Thanks. What is the correct pid to log maf hz?

[joecar]

For Gen3 (LS1A/LS1B):

GM.MAFFREQ

[Tool Guy]

I don't see it on the list. I only see GM.MAFERROR and GM.MAFFREQ2. I validated the pids with shift+f2. Also, I can't find coolant temp. I sorted them by selecting units then trying each one. What should I do next?

[Tool Guy]

I unchecked the supported tab and i found it on the list. It validated the coolant temp sensor but there is a red x on GM.MAFFREQ, GM.KR, GM.EQUIVRATIO, AND GM.IBPW1. How do I get them to validate?

[joecar]

Hmmm... those pids should be valid on LS1A.

After connecting scantool, try doing Info->Validate Pids.

[Tool Guy]

I did. There was no change. Also, I just updated to the latest versions of 7.5 & 8 and now more pids are invalid. I don't have rpm or engine temp anymore.

[joecar]

Can you post screenshots of the invalid pids.

Go Help->About in the v7 scantool, what version does it say...?
