Am I crazy or has anyone else experienced this? I am what you could consider an "aggressive" driver. This includes abrupt stoplight engagements and WOT frolicking. I usually get about 18 mpg during my excursions, but a recent ECU reset has given an extra 1 to 3 mpg. Of course, I have no sophisticated measuring equipment to back up my claims...just a calculator and a gas level indicator. Someone with NAV could actually get more accurate results. Nothing drastic, but this makes sense in theory. If you drive like grandma, then an ECU reset may give you more power, so why can't an ECU reset do the opposite for an aggressive driver? Let's discuss...

 

How do you rest the ECU

 

Going by the gauge and/or nav is not a good way of calculating MPGs. The only way to do it accurately is to divide miles by the amount of gallons it took to top off the tank.

Usually resetting the ECU will result in worse MPGs because the closed loop A/F ratios take a while to adjust on a reset computer. For safety, the ECU intially chooses richer A/Fs which both make for worse performance and worse MPGs.

IMO, resetting the ECU to find more MPGs or performance is BS. It's just one of many myths perpetuated on this website that have absolutely no credible base. It's just a bunch of heresay.

 

I tend to agree. For my last ecu reset, I used the EASY ECU RESETTING method and the car felt noticeably sluggish. The funny thing is that after I did the Groundinggear I did the battery disconnect method and there was definately an improvement in performance.

 

Not true as usual.

I drive 100 miles a day and get to fill my car up almost twice a week. I have done ecu resets and seen a 1-2 mpg increase with them. Driving habits are always the same. Others who have done this and calculated the mpg correctly have also seen a small increase when doing so.

MYTHS? LOL Dave, how much more bs you gonna spew?
