Not even just emissions, lots of companies play software tricks to game efficiency numbers. Chevy and Ford have both played games with the manual V8 sports cars that locks out the 1 -> 2 shift and force the driver to go 1 -> 4 to save gas when the computer sees the car accelerating at the same rate as the EPA test.
The funniest thing was the Ford would sell you a software update to defeat skip shift under the guise of a "performance tune", at least that's how I defeated it while still keeping my warranty.
- jdhn 10y agoI was under the impression that unless you bought an aftermarket tune the 1 -> 2 (and maybe even 1 -> 3) shift was always locked out no matter your rate of acceleration. Has this changed in the past few years?
