I'm using Chevron and he suggested I try Shell...

So I'm currently getting a custom tune by Johan and we have a knock problem. I'm logging a 4 on short term knock at WOT. I've been running Chevron 91 octane and he said the Techron may be the cause. So I'm going to try some other gas and log that.

Here's my dilemma, Shell 91 octane is 60 cents a ...

It was. My bad.

Ok so I tried to turn off my MDS today and couldn't find where it's located. I went to advanced tune and modify parameters but there's only transmission, traction control, and tires. MDS isn't in any of those.

I know this question has been answered here before but I can't find the post. If I get a custom tune and want to change a few things like throttle response and shift firmness, am I able to do that without messing up the custom tune?

Ok, so I guess the first time I plugged it in the calibration didn't occur but I just tried installing the 91 octane tune and it worked!

And a calibration update just uploaded after I submitted it. Here is the new xml file in case it's different.

Here you go.

Just received my intune i2 and tried tuning it today and got the message that my vehicle is not supported. I ran the update tool and it said no updates. Is my car not supported?
