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.

[joecar]

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

[Tool Guy]

I have attached two screenshots. Both the Pid list and the about page

I'm assuming you're using a laptop...

Hook the interface up to the OBD2 port on your vehicle.
Turn the ignition key on, but don't start the engine.
Click File > Select Controller... Set the correct controller type for your vehicle.
Click the 'connect' icon in the scantool.
Validate your Pids.

Let us know if that helps at all.

Statesman: I did what you suggested, and the situation is unchanged.

[statesman]

There's something weird happening with either your software or your device. I looked back at your old posts and you had a similar problem tuning an E38. Try removing all the selected Pids from your list and then just select gm.maffreq and see if it validates when no other pids are selected.

[Tool Guy]

statesman: I did what you suggested and it worked. I unchecked all the other pids except for GM.MAFFREQ and it validated it. What do I do next?

[statesman]

Okay, this is definitely a technical issue with your flashscan. You'll need to contact Efilive support and see if they can fix it for you.

[joecar]

Now try adding some of the other pids back, like SAE.VSS, SAE.TP, SAE.MAP, GM.MAF

and see what happens.

Could you please try re-validating the PIDs while connected to the vehicle/controller and once that is complete, select the menu option: File->Generate error report. Save that error report and email it to me at paul@efilive.com. Include a link to this thread so I know what it is about.
