I recently purchased my first Lotus, but have an issue that I would like your opinions on. I have searched, but can't find the answer I am looking for. After the car is properly warmed up and I get on the throttle the tach is very laggy and seems to just stop at around 5k RPM's. I can hear the second cam kick in and then what sounds about 2k RPM later the shift light comes on and I hit the limiter as I think it should, but I would like to get the tach to respond how it should. I have tried the reset procedure with the rest button on the column, but the problem remains. Any ideas would be greatly appreciated. I am in Utah, so there isn't a dealer anywhere close to me.
