I don't know what it all means but I think I have a BINGO in there somewhere. I hope I got them right. I appreciate your help.

A24 isn't on the list guys... and GX3 means you have a 3.33 final

FR2 - ratio, transaxle, final drive 2.93
FW2 - ratio, transaxle, final drive 3.06 <this one rocks
F17 - ratio, transaxle, final drive 2.84
F79 - ratio, transaxle, final drive 2.97
GX3 - ratio, transaxle, final drive 3.33

when the transmission is in third at WOT but the gear selector is in drive
my stock pcm doesn't have the 108mph speed limiter
but if my gear selector is in third i do have a 108mph speed limiter
go figure..
3" cat back exhaust, 3.33" pulley,k&n filter in the stock air box
and for my 1/4 mile times, the gear selector is in 2nd. i go through
the lights at 96mph in 2nd gear.

74 mph is 2000 rpm in my car.
my car has a stock pcm.

How sure of these shift points are you? A Stock 00 PCM shift points are

1-2 5350
2-3 5350
3-4 4400

with a rev-limiter of 5950

What was your 60' time on your 1/4 run?

rrounds 05-10-2004 07:30 PM

best 60' time of 2.138
worst time of 3.893
1st and 2nd gear shift points actron 9145 super scanner
3rd gear by the car tach.
Rod.

2500 is pretty high. The final drive ratio and your tires determine the rpm but in general, our cars run about 36mph/1000rpm so you should be around 2000.
Start from a stop and you should see the 1-2, 2-3, 3-4 shifts with the torque converter locking at about 45 once you are in 4th and moderately accelerating.
It is also possible that the tach is off.
Oops, didn't realize there was a 2nd page and since you have the higher axle ratio, your number is probably about right.
