ME7.x tyre size scalar
« on: March 30, 2013, 07:16:04 AM »
Hi, I am battling to find the parameter which is used to calculate the road speed. This is of course based on the rolling radius of the tyres. I know this is stored somewhere but there are hundreds of parameters in the Damos file all in German! I suspect it's a scalar used on the speed pulse input.
Because the tyre size is incorrect in my tune the engine DME thinks the car is moving faster than it is at the moment. Not sure what effect this has apart from hitting the speed limiter sooner!
Can anyone tell me the register I need to look for please. I suspect ME7.1 is the same.

Thanks. I had not seen that page before. The down side of getting the road speed correct is my car now does about 5mpg "less" !!!!

But you also aren't traveling as far/racking up the miles as fast
