Mr. Happy

I'm quite keen on getting my Kleemann ECU upgrade next week. Although the upgrade is probably more obvious above 60 mph, does anybody know by how much it reduces the time to go from 0 to 60 mph?

The answer we give you would be very vague because 0-60mph times have way too many variables to be calculated properly.

If you are kind enough to give us your attitude, location, temperature, tire width, tire tread depth, launching surface, etc in exact details then we MIGHT be able to tell you.

If you just want to have a super low 0-60mph time then just go and buy yourself a pair of rear drag radials.

yah, 0-60 times don't mean much for 400+ hp cars. The C63 ranged 3.9-4.3 seconds in the 0-60 in road tests. That's almost half second range which is quite large. Its very difficult to gauge what the real 0-60 time for a car is because it depends on so many factors such climate, particular vehicle being tested, etc. I think the best way to go is by the best test number available which is 3.9 seconds and I doubt the K1 package can improve much beyond that in that power band. The 0-100 may improve by a few tenths though. The best 0-100 I've seen for the C63 is 9.3 seconds, so maybe close to 9 flat?

If your getting the tune your least concern should be the 0-60 time. Like the above post, you would be better off getting drag radials for that. It really shines in above 40 MPH speeds. Basically at any speed after that when you step on the gas, it will take your breath away!
