tested during dyno? if dyno also cannot hit above 190kph, then it's speed cut. reflash means you alter the whole programming instruction on the ECU. should work if there's no instruction on speed cut. Else, its the TCU issue.

Added on January 16, 2012, 3:06 pmif dyno can go above 190kph, then its other factor.

In my opinion, the new honda city can go further than 190km/h...1st because the rpm didn't hit the edge of max rpm...may b it can go up to 210/220 km/h...i didn't know..hehehehe..but i do had experience when my speed at 190km/h..other new honda city "potong" me at more higher speed...tht's why i got so curious abt the speed..hehehehe

bro...i dont think the engine has reached its maximum speed output....full throtle on the gas paddel, when ever i reach 190km/h the engine will give me this slight jerking and thump sound...then i will have no respond on the gas paddel...when ever i go down to slight below 190km/h..i will have my gas paddle respond back..it's not that my speedometer stuck at 190 km/h...like you claim for engine that has max out its speed potential.

for a few time i have manage to push the speedo meter to reach at 200km/h....then the thump sound and slight jerking from my engine occur and there is no respond on the gas paddle..like there is no gas going to engine kind of feeling..but after the speed is reduce to 18+..the gas paddle will respond back providing the gas feeling to the engine as usual.

for this i dare to claims that my car are equipped with speed limiter...yes i do understand all the jdm car will have the limiter and limit up to 180 km/h...and for this wierdness of my car behaviour i have come here to seek all the senior and sifu's opinion...really hope all the seniors and sifu can teach me and providing me your valuable opinion.
