Shift Light

[renzop]

A shift light will only help you with up shifts. If you overrevved because you down shifted at too high of a speed for the gear you were going into then a shift light will not help.

Also, for a track day, why in the world would you be upshifting at redline anyway? You are not competing, give the engine a break! Our cars do not produce max HP at redline. By the time you get to redline the power curve has started to fall off.

You said you did not have time to look at the tach. Then something is really wrong. This is NOT A RACE. Slow down until you can calmly do whatever you need to do, like look at the tach when its approaching shift time. Your car and your instructor will thank you.

Do yourself and your car a favor, forget the shiftlight and try to shift earlier. If you lose a few tenths of a second so what?

I have Boxster s year 2000 with 6 psi supercharger, intercooler and methanol injection. Last drag, i made 12.7 with 107 mph. Huge experience. To do so I had to add shift light to help me keeping concentrate on the road. I removed cluster from dash board and unplugged RPM. It is a long white plug. If I remember, the rpm signal is the second lower pin. Anyway, just take voltmeter on 12 volts mode, put black on ground, start engine and search pin that send signal by playing with pedal. After that, just plug your remote RPM with shift light. If you have separate shift light, just stick it in front of you on the dash. I set mine at 6200. I saved close to 1 second on performance

You can get a rpm signal from the OBDII plug or for the back of the instrument cluster.

If you go for the cluster don't use the instructions in the link because you have a 2002 and the wiring to the instrument custer is different.

I used the tach signal on the DME to feed my HKS CAMP system under the passenger's seat. This has an adjustable shift indicator that's audible, but no actual light. My Knock Link knock sensor pretty much operates like a shift light though in conjunction with the HKS CAMP. As the revs get towards red line the CAMP gives me an audible signal and the Knock Link starts to light up. This usually helps to keep me from bouncing off the rev limiter.

Happy you succeed with shift light. You will find it very usefull. If sometimes you have to remove cluster, it is a matter of couple of screws and 2 or 3 minutes to remove. It is not what it looks to be. These cars are so well built.
I find shift light very usefull with my boxster when I quick start. The car is now so powerful with upgrades that I spin in first, second and third. It prevents always been in red zone. And as soon you reach 100 mph and more on drag circuit, you are concentrate in front of you. So the light talks when it is time. If you want to see some pictures of work I did on my Boxster, you guys can go to : performances talk, under boxster intercooler (pinzgo)
Have nice day

How do you like the Camp? How does its functionality compare with the scan gaugeII? Do you have a double din dispaly working with it? How painful is it to get oil pressure indication?

As an instructor, I frequently observe students and listen as they hit the rev limiter from certain track vantages. I also agree that a shift light is really not the answer. What novice drivers need to learn is track awareness and how to use the proper gears and when to shift based upon that awareness. Remember to start slowly and build, not only your mental position on the track, but how the car is reacting to that situation; you will learn where the power band is and where is it most advantageous to shift.
