215 miles per tank. After brand new radiator/ecu flash . Why?

Any reason to this? 2-3 tanks filled up and 215 or so miles per tank.
They replaced a bad radiator and reflashed the ecu
Scheduled an appointment today, will cancel if anyone thinks it takes way longer for the ecu to adapt. But low 200’s doesn’t seem right.

 

Because you can’t go 216 miles.
I believe your vehicle needs to relearn your driving habits. Similar to when it was new

 

So what if it relearns to stay at 200. That makes no sense lol

 

Why the ecu reflash??

 

The lagging update/surging.

 

Is this the Distance to Empty that is being shown, or is this when actually using about 20gal of fuel? I.E., you are getting a calculated 10mpg using the trip meter and the fill up volume from the gas pump?


If you are actually getting 10mpg, then the dealer hosed something up. If it is DTE, I wouldn't worry as long as it is generally accurate for the last 1/4 of the tank.

 

Filled up. Odemeter when light almost turned on read 215

 

Average 385 on mine to a tank

 

Didn't know if it was requested or something the dealer did that was not requested.

 

Thanks.

There is typically about 3gal left when the light turns on, so that is 12mpg and is not good. If they only swapped the rad and flashed the TSB, no other work listed, then something is odd.

You might ask them to Reset the DTCs and Learned Values. They should do a 5min idle touching nothing after this. That first drive will feel weird, but it may fix the problem. They might have skipped this when doing the flash?

 

I guess we will see I’ll take it in for sure today. Got an apt at 2. They suck.

 

Good luck!

12mpg is not 'normal.' Your ECO display will prove that to me, just in case.

 

all I got.

 

Not that screen. Hit the Past Record button for your entire history since new.

Your current DTE looks good though?

 

Looks normal

 

Disconnect the battery for about 15 minutes and it will relearn everything. Do it while filling it up with gas.

 

...then run a tank or two through and see where it avgs then. Learning takes time after resets.

 

Note though that a battery disconnect is only a partial reset. The LV Reset is a clean slate.

 

RESET IT ALL!!!!

 

That is my jam. ------>

Me likey an empty book that I can fill all by myself.
