ECO PRO disables jb4??

nikhil1423 · 10-15-2015, 04:37 PM

I was driving in ECO PRO earlier this week (don't judge me I had 40 miles of range and 45 miles to go before fill up) and after some time my check engine light came on just as it used before my JB4. It was coming on because of my downpipe I believe because there were no other warnings.

After switching back into comfort, the light was gone within 5 seconds.

I also noted that the JB4 was still active because i tried switching maps and it was operating just fine.

No real problems here, just wondering if ECO PRO puts the car in some sort of bypass mode that would ignore the JB4.

Ideas?

It shouldn't but I would email Terry and make sure you have the most up to date firmware as early firmware had sporadic CEL from downpipes still coming on.

interesting question.

It would be really cool if it does that

That's what I'm thinking!

It does not! Eco just creates a very fun turbo lag. 100% of the power is still there.
