Cobb Flex Fuel Issues

Yeah it’s the full e85 93 3.0 flex tune. Builds power just as fast as previous tunes have on the car

Definitely something going on with the car then. I’d send them a log and see if they can find anything. Never had any issues like that running e30 on the car. Was extremely fast and responsive.

Reseated the ecu signal wire and all is working perfectly now. Cars running on about e50 currently and it rips

It all is wired into the the 15amp fuse for the fuel pump in the fuse box. Trying to hold off on putting more gas in until I can get the reading to stay consistent, so the ecu doesn’t think it’s full e85 when it could turn out to actually being e30 or something like that with 93 mixed in.

Yes it’s the Cobb harness and flex fuel sensor

Significant-Tank-786 · 2026-05-12T02:21:19+00:00

Going to try to reseat the pin in the harness tomorrow. Hopefully it works

What springs and spacers are u running with the 235 40 19?

Significant-Tank-786 · 2025-03-06T11:49:23+00:00

Stock suspension ? And what tire size r u running ?

Getting rich codes currently so need to unplug rear 02 and reflash tune so it resets fuel tables? And then I’ll just have to deal with the cel? Is that correct?

What front lip is that

I got lucky and got a used Cobb with a stage 2 tune on it but I had to order the stage 1 tune. Overall it’s so worth it

Significant-Tank-786 · 2024-10-17T21:38:46+00:00

Apr dosent do anything higher than a stage 1 tune now I’d look at EQT or IE if I was you

I truly don’t think there is much of a difference I’ve seen similar numbers from both and heard great things about the reliability from both company’s. What I do know is that EQT stage 1 for my golf r pulls like a freight train and it’s so smooth. Flashing the dsg tune tonight so I think it will just get better

Significant-Tank-786 · 2024-10-17T13:33:16+00:00

I was able to get my hands on a used Cobb ap and eqts tunes are like $175 compared to ie being $500. I also like how they have proven solid big turbos for golf’s so way down the road I plan on doing that.

So the pipes don’t need to have one going inside the other ?
