Hey guys so I'm having some trouble. My car is throwing an ecu failure code. Talked to Hondata and they said corrupt file so I reset to factory tune and than to current tune. Still does it. 1-3 gears my car rev limits @ 8500, however, in 4th, it doesn't rev limit and goes to 9k+ and throw the ecu cel and puts my car in limp mode. Turn my car off while coasting and back on and it's fine but cel stays on for a day or two. Any ideas? A buddy of mine said his friend had the same problem in a Mazdaspeed6 and it was a speed sensor. Also thinking maybe a crank or cam sensor? Need help
