Interior lighting

[2young944]

Does anyone know how to make the instruments on the interior of a 944 any brighter? This is for a late model 944. Also, what is the little orange arrow on the NA944 tach? It only goes bright on occasion, or just cruising speed. Thanks!

Not sure on the lights on the late cars, but the arrow is the shift light telling you to upshift for the best fuel economy.

That thing comes on early if that is the case. I suppose it would make sense to shift early for better fuel economy, but come on, nobody buys a Porsche for the gas milage! I never shift that early, the car shakes and lugs if I do.

You're not supposed to have the engine rpm drop below 1600rpm. The light will NEVER come on for an upshift if the revs would drop below 1600 in the next gear...

Also, if you're flooring it, the light should come on about 50rpm before redline, but in MANY 944s, you'll hit the limiter first... I've replaced my tach twice, and both were the same way (light comes on AFTER hitting the rev limiter), well I had to get mine rebuilt to get rid of this little annoyance, oh well.

Basically the light is there to tell you, that you'd have the exact same acceleration in the next gear. (But lower rpm-->better gas milage!) However this isn't very usefull, since the DME doesn't know that there's a passing zone, and a slow car in front of you, or a tight turn coming up, whatever. So you're keeping the car in that gear on purpose, (to use max acceleration, or to stabilize the car, etc.)

In short it's useless!

Anyway, making the gauges brighter? You can replace the bulbs with something brighter, and wrapping aluminum foil in the gauge cluster cylinders works on the later cars as well... (on the inside).

Hope this helped,

How do I get to the backside of the gadges? Thanks for your help

Well, you need to pull the gauge panel out, it's suggested that you pull the wheel to do this, but I'm not sure if it's mandatory...
