Wrong rear end gear ratio and tire rev per mile on ecm - Nero - 01-25-2024 Ecm had 2.64 actual ratio is 2.79, and tire rev Was at 516 correct rev is 509. Speed was off by 4 miles. I corrected both, the speed is accurate now. Is my total mileage off 460k?

You go poking the bear on purpose, and next thing you know, you will get investigated for ODO tinkering. - Not something I would recommend. Its best to get it set right, so that its accurate, and keep it there. |
