Pics of 996 Carerra cluster into Boxster

Calibration is usually necessary after replacement of the fuel tank, fuel level sensor or instrument cluster. This requires removing and refilling with exactly12 liters of fuel. Then using a PST2 (or PIWIS tester) to re-calibrate the cluster.

You might try just filling the tank and disconnecting the battery and then reconnecting the battery which should give you a minor recalibration as it resets everything.

Thumper-

Exactly how do you get exactly 12 liters of fuel in the tank, short of draining it?

Should I first try filling the tank completey and re-setting the DME and cluster by removing the battery lead for a minute first?

This brings me to another question: is there a similar process to calibrate the oil level gauge? So far it appears accurate, as the previous readings from the 986 cluster and the 996 cluster agree, which also corresponds to the dipstick readings.

I would try filling the tank and then resetting by disconnecting the battery and reconnecting it. It's definitely worth a try. I filled my tank in preparation of swapping out the cluster. I'm doing mine over the next couple of nights. Worst case, I'll take it in to have it recalibrated. I can just imagine what that would cost.

I don't think you can calibrate the oil pressure gauge. But I could be wrong and probably am.

Well, I'm going to fill it up and re-set the DME and cluster and see if its happy as the fuel level goes down... if all else fails, I suppose I'll have the stealership calibrate it.

As to the oil, I only asked if it was possible/ should be calibrated since my seems to be accurate still.

If you have to have the stealership calibrate your fuel gauge, you might pose the question about the oil pressure gauge. They might be able to check to see if it accurate as well.

Nice looking gauges, Patrick. I also like your Eclipse unit. My top choices were that one (5510?) and the Pioneer I ended up going with.

the resistance values of the floats may be different causing incorrect readings.

Thanks for the compliments. The 5510 is great.

I'm going to try topping off the tank tomorrow and pulling the negative terminal to reset and we'll see if that does the trick. If not its off to the stealership.....
