So, compared to GPS, my Speedo is consistently 5mph too optimistic. My tires are 195/65-15. I’ve read in other threads that has shown to be a good size for correcting error.
So, not really wanting to go taller still, is there any other way to calibrate the Speedo? Thanks, Van |

As an Air Force guy, I don't want to be any more reliant on GPS than what we already are ... tunnels, cloudy days, wrong area for sat coverage and your needle will develop ED real quick lol...
Clay, I do have a couple questions for you though. Are you saying 195/65-15 is still too small compared to the mostly undefined 165HR15 OE tire size? Also, is there anymore info on adjusting this tensioner I can look at? -Van |

(IMG:style_emoticons/default/agree.gif) Dan After a while you get a feel for what RPM you are turning in a particular gear for a particular speed. So if my GPS driven speedo stops working, I can get buy close enough to not get a ticket. But when it is working, it is deadly accurate. And with the Cayman 6 speed transmission, there is no place to drive a speedometer on my car. Clay |

After a while you get a feel for what RPM you are turning in a particular gear for a particular speed. There is that. I took a 10-hour round-trip in the 914 last weekend and found myself using the front-and-center tach for speed (for my car a needle-width above 3000 was ~71-72 per Waze. Of course, then there's the Waze display...) I'm personally not too worried about GPS taking a dive. I'm certainly not minimizing the concerns - overall society is gonna be in a heap 'o bind if the military is forced to degrade or restrict the signals - but I can work around quick/short-term losses of signal. - GA |
