AFD ProFlex E85 Commander Journey w/ GT350

[rag11]

no point speculating until you check in the codes. Mine threw a lean code on bank 2 with the unit plugged in, it eventually threw lean on bank 1 as well after unplugging the unit. Seems like it's adding some fuel on bank 1 and none on bank 2

Coded P0174 Lean on bank 2......same as you right?

AFD is sending me a new one as well. Likely a small bad batch. Even if you filled up with e85 once without any proflex installed, itd be unlikely you would cause any long term damage from doing it once. You wont know if yours is working or not til you try is all.

Yes, but if you guys get the new box installed and it does not solve this issue, then what? Not sure if I should even waste my time. I'll send it back and use the 800 for more track time

Talked to AFD today. They attribute the issues to a limited manufacturing process defect that likely overheated the chip on a batch of GT350 commanders. They already QA'd the process, made changes and will be sending another out. Sounds like the replacement version has worked for other customers and they seem very willing to make sure we get taken care of. I'll add to the other member's posts and let you all know after it arrives and I've driven around a couple days on a new commander with a full tank of e85.

Y'know, for the sake of a little risk management, you might want to run a 1/2 tank of E85 first and see where the fuel trims go. If they stay "normal" around 1.0, then all is well and you can go to a full E85 tank and forget these teething problems ever happened...

STILL WAITING on my replacement. I asked USPS to redeliver today because i missed it yesterday (sig confirmation), but of course they never came. Left my signed ticket and everything.

I got E38 in the tank, gonna try the unit with that first, check the trims.

 

[mmakam2]

Eh, this is on USPS not really AFD, though it is annoying not to get a tracking number.

 

[lightrules]

got my tracking#, says Saturday arrival. waiting game continues...

 

[mmakam2]

wooo! Just picked up my brain from the post office. My car is off getting ceramic coating so I get it back at 5pm. I should have an update tonight on how it goes with the new unit.

 

[mmakam2]

so far so good guys, E50 in the tank, trims are about +7% but they are still settling down as the car is learning. Only put a mile on it.

Will keep yall posted on how it runs tonight, going to do some hits and top it off ethanol.

No backfiring btw.

 

[mmakam2]

not sure guys trims are 30%+ under load and the bank variance is back.

Has not thrown a code yet though.
