[200q20v] Speedo help.

[Richard E. Berlin, Jr.]

 My last '91 Avant,(oem rims and 215/60 tires) always
measured 72mph when the rev counter  was at 3000 rpm's in
fifth gear. In addition, when I would reset the average
speed button on the computer, the initial reading always
corresponded to the reading on the analog speedo gauge.

The newer '91TQA  (identical rims and tires) measures 77mph
on the speedo gauge at 3000rpm's in 5th gear. But when I do
the average speed reset on the computer, it reads73mph--4
mph lower.

Could it be that Audi put 2 different rear ends in these
cars?? I remember reading an ongoing thread several months
ago where Chris Miller and another lister were contending
3.89 vs 4.11 ratios as OEM??

Would you guys run the 300rpm 5th gear test and let me know
what speedo and avg speed reset readings you get? In the
mean time, I'll hit the Mass Pike with a stop watch over
some measured miles.
