I have installed the prl flex fuel kit. Now that I have this installed, do I need to do anything in ktuner and upload to the ecu? I feel like some people say you need to turn on a flexfuel tune and others say it is plug and play and once it is installed you can use ethanol right away provided you have the correct ratio of ethanol and unleaded.

Contact prl.
They will support well with detail. Turn on (check)flex fuel at advanced adjustment and disable 3 obd2 monitoring (sec. Ect sensor, coolant op temp below...., and turbo underboost condition) otherwise it will throw P0128 code.

I am constantly running stg 2 flex fuel at E30 to E40 for 9k miles with no issue.
Clutch still grabs hard.

How do you like the flex fuel tune so far?

Wow... what a beast!!! Would love to see/read more about your car. No way I would trust that much TQ/HP on CVT though. 😬

those hp number seem high for E50, AccordingtoJoel.com has the fastest 10th gen atm, with im pretty sure the highest HP numbers also. He is at like a E75% blend making 415 hp and like 410tq

Yes. Please see attachment. Also, I highly recommend a pro-tune.

Installing the PRL flex fuel kit on my 1.5t. Seeing as this product is fairly new, I get not having much user-created content yet from other's who have installed these on different models, but it would have been nice if they had provided some detail for specific models. I'm stuck at the point of connecting the optional voltage output, which they say to plug into the ect2 sensor. I have located the sensor, however both the end of the sensor and the cable that is supposed to attach to it are male ends. I'm trying to logic what is supposed to happen here. Is the cable supposed to be connected to the factory cable that leads to the ecu? I guess this makes sense for turning off the codes in tuning. Anyone know?
