Valve Spring Recall Affecting Fuel Economy?

[bcj]

If they didn't disconnect the battery before pulling the whole engine out,
I'd have some very scatological invective to share with them.

They told you not to hammer it because after 1,000 miles if the engine blows it's harder to pin the blame on them.

It shouldn't be. There is a 12mo/12k mile warranty on the work. The dealer that did mine actually told me to go out and drive it hard after the first few days.

Forgive me if I'm a bit jaded probably not the whole truth

After more than a thousand miles, my mileage is down maybe .5 MPG. I did get a map update out of it, though nothing was ever mentioned about this. Wonder if other things were done such as an ECU update?

Should I try to reflash my tune? I am using an OFT tuner

Why not. What do you have to lose?

.5? That is well within the difference expected with cold weather. There is nothing wrong with your car. You don't need to change to tune. It isn't beyond what would be expected and will go back to "normal" when it warms up outside.

No, I get it. I was talking about the satellite map getting a free update, and then wondering if anything else got updated. I'm fine with the outcome so far.

The map is a whole different thing than the ECU. No cross over. There were probably at least a couple of head unit updates they had to do. They just can't seem to master those.

I'm basically the same before and after.

I suggest you check your fuel mileage the old fashioned way - with a pencil and a piece of paper. Check at least 3 tanks full.

Sometimes, those electronic things lie -

I check it both ways and find the car calculated MPG is very accurate. That is, assuming that the car calculates correct mileage, which is sketchy, because GPS MPH readings are always lower by 1 or 2 MPH than what the digital speedometer says it is. So, even if your using pencil and paper, you're still relying on the mileage that the car calculates which may or may not be accurate.
