the calibration addeed (3 )ECM numbers.. and for my fellow LedZep fans - " the Firmware remains the same " - dated 8/29/2007

 

i am running in economy now / from performance - i've notice that it doesnt shift into V4 as much, plus you can really tell that she's been weaked by a noticable amount - I'm going back to performance mode and 13 mpg city - DOAH !!!

I too recently (2 tanks ago) switched from Extreme to Economy, running on 92 octane with each and to be honest, I have noticed very little difference in performance in daily driving (no 0-60 runs, etc). I have not noticed ANY increase in mileage going from Extreme to Economy. I am getting about 13.5-14 on each (90% city). However, I switched from Extreme to Economy about the same time we started getting "real" winter (snow and sub 20F temps), so that may have offset the mileage increase making it equal. I am still in "experimenting" mode. I am going to try Economy with 87 octane next to see if there is any mileage or noticeable performance change.

i also noticed that it doesnt go into v4 mode as easy. it feels stronger to me though in power and shifts a little different. can you swap back if you want?

not sure what you mean? You can swap back and forth between tunes any time you want to.
