I should’ve posted this a long time ago. I ended up taking the car to the local dealer because I was concerned, and interestingly enough, Porsche scanner shows my LTFT’s are +/-2%, but the $20 OBD reader shows them as much higher…

I tried it again at a local indy a few months later and exact same thing. For some reason the cheap-o plug-in OBD scanner reports a falsely high reading, even though the true values are perfectly fine.

Just something to be aware of when doing DIY troubleshooting.

Fantastic feedback.

let me check it against my Foxwell reader.

My OBD2 $100 KiWi3 reader and my Foxwell 530 read the same. LTFT 6% adding fuel on both banks.

hoping that’s the 10% ethanol in our fuel that’s causing by that or maybe I have another tiny vacuum leak somewhere.

Be sure to hook up a proper scanner before you embark on a wild goose chase. I’d be very curious if your results are similar to mine, meaning ELM
shows a false high value.

Fair.

I’ll chat with my Indy.
