Switching from Not to EFI Live

[Philbar715]

I use to own HPTuners, and tuned the car myself with hpt. I did not apply the custom two bar OS. I did however apply the MAF TCS patch using HPT.

My question is since I've done that will EFI Live be able to read the ECM?

This is in a 05 GTO with the E40 Ecm. I asked this on the HPT forums but didn't get a reply there...

I do have a tech Ii so I can flash the stock calibration with that if I need.

I have both but never tried to read a e40 after maf patch. It should read it. It may show that part of the file to be corrupt or out of range. try it and see.

If you're able to read it, post it here.

Pretty sure you'll be fine to use it as is unless for some reason they change the ECM Operating System number, best bet as others suggested is just try reading it out.

Once I get my Flash Scan 2 I'll give it a whirl and let every know how it goes.

Have done this before, it will work.
