Here are the results of back-back simulated acceleration tests for my car.
Firstly with the factory limiter set to 6750; secondly with a limit raised to 7200 rpm.
PS - The unichip Q allows the rev limit to be raised; based on the assumption that an extra 450 rpm won't blow up the KV6
.
The two images show the acceleration from rest to 100 mph.
After 100 mph, the times were as follows:
Standard rev limit
0-110 - 21s
0-120 - 28s
0-130 - 40s
0-140 - 62s
Raised limit
0-110 - 20.5s
0-120 - 25s
0-130 - 36s
0-140 - 59s
The biggest difference here is that with the raised limiter, 4th gear can pull beyond 120 mph (standard 116/117 mph); hence gaining 3 seconds over standard.
Bear in mind these figures reflect the current state of tune of my 180.
This gives a 30-130 time of 33.6 or thereabouts (raised imit) vs 37.6 standard limit.
So the question is; is it safe to raise the limiter to 7.2k?
