E85 Tune
Hey guys, I'm a new member and have a 2016 Z07 A8, with an AFE CAI, a CS catch can and an e85 system installed, but not tuned as yet. I did the e85 install myself, as I installed an Eforce SC on my C6 Z06 without any problems a few years ago. The two cars have about the same power, but the fit and finish on the C7 is much better inside. Question is, can anyone confirm for me that I pinned the right spot, pin 38, on the ECU wiring harness, from looking at the pics below. The brown and white wire that's a little crinkled is the flex fuel signal I installed, as it was tough to get it to click in for some reason. I went down 6 and in 1 and the wiring loom is towards the top of the harness in the pic.
Thanks much.
Thanks much.

Thanks, it looks like the same spot, but from a bottom view of the harness. Not sure why my harness looks nothing like that from the bottom though, it may be that the year or model makes a difference? Does any company sell an e85 tune, instead of having to find a reliable tuner? I have never used one hear in the Bay Area. I have the HP Tuners VCM.

You need to pry that blue plastic part off the face of the connector, then it will look like my picture. Im pretty sure that is also what locks the pins into place, so you'll want to pop it off before inserting the new pin

Ouch. Do you know if there is an issue if I didn't pry the blue part off. I had a hard time inserting the wire and getting it to click, but I was able to get it to click in with a pair of needle nose pliers to push the wire down and it wouldn't come back out. Thanks for the info.
