I am told only one person has found it and that is lsxworks. I'm sure someone has to know. Trying to do a Flex Sensor integration on a 2009 CTS-V. I can not find anyone that has done this on a e67 PCM for a ctsv yet.

Yes I know you can do a 12v single to do the e85 but this integration would create multi maps based on the %.

To sum it up just like haltech's setup

To understand the method watch this vid

What do you need to know?

In order to wire in and get the flex fuel sensor to work I need to know which E67 ECU pinout will read the sensor frequency and duty cycle and apply it to the tables. EFI has these tables.

Like the haltech setup does...

If you could find it that would be great. I will be ready for tuning next week :)

HPTuners is working on this too, already in all E38s and they're working on E67s now. I imagine that info will be posted when they figure it out.

Someone has already bench tested it but gotta wait for the release. Which I don't want to do

What OS? Unfortunately some P10 OSs dont work like they should in EFILive, either have to upgrade the OS or use HPTuners to do it.


Try setting B0515 and B0517 to No and B2501 to a higher value.
There are also a few rev limiters EFILive doesnt have that HPTuners has, try this otherwise we might need to request some more tables.


I dont know who you're using for tuning, but I would never recommend using a stock OS for a boosted application. That's the entire reason that EFILive and HPTuners spent lots of time and money to develop the COSs.
