E-85 and Emissions

[JVO21303]

I know this has been talked about a lot on here and I hear people saying different things. I have LTH with high flow cats. And people with similar setups have pass emissions with this setup and a good tune. Will E85 not run hot enough for the O2 to get up to proper heat levels. I also have extensions on my rear O2 so no CEL has ever come on. My tuner said with this setup I will most likely not pass emissions.

Have you gone through all of the readiness drive cycle procedures?

Who is your tuner? The good ones can make this work.

The O2 heater has nothing to do with the heat of the exhaust.

I run pcmtec canbus flex with blends varying from e10 (93) through e85+ on my whipple gen 2. All cat and 02 monitors are ready. Exhaust set up is kooks 1 7/8 GESI HO Green Cats into AWE touring catback.

As previously stated, you may need to complete a few more drive cycles for them to become ready if new tune was recently flashed or battery changed.

My gut feeling is that the tuner disabled one of the monitors in the tune to prevent the CEL from coming on and that is why tuner is saying it probably won't pass.

HP Tuners older software has the ability to modify emission parameters, testing, and readiness monitors that the current software versions no longer support.

Yeah VMP tuned it. They’re good for products but they’re tuning sucks and they’re tuning support sucks

I recently had a wheel hub go out and it messed up my wheel sensor so I had to perform a reset. I got around the emissions till 2028. I’m gonna go with wengerd tune ASAP.

Justin used to be good. At least with the S197’s.
