Programmer's stopwatch accuracy?
Is the general consensus that the stopwatch on the Gryphon and/or Edge should be considered accurate?
as far as 0 to 60 and 1/4 mile timing?

why?
seems like it should keep a fairly accurate reading for 0 to 60 anyway.
And doesn't Car and Driver (and others) use a similar type electronic timer for recording their 0to60 and 1/4 figures during roadtests.

they use a gtech and they use it to show the increase after a mod which in that way it will give an accurate increase amount but the actual time/hp rating will most likely be off

As long as the Tire Size and Gear Ratio are correct, the 0-60 time is pretty accurate. The 1/4 mile stuff can be inaccurate depending on things like wheel-slip and other factors. Because the unit depends on CAN messages from the ECM and the messages can only be requested every so often, the acceleration calculations may be a little off in 1st gear which will effect the final values. It is usually pretty close but I wouldn't bet any pink slips on it.

Well I know my tire size and gear ratio were correctly identified in the unit..........and even if I add .5 sec 0 to 60 then I'm dam happy with my 87 performance tune from Bill.....I posted some dandy runs that it wouldn't do before on the canned tunes!

Well, consider how accurate the horsepower readings are with the Scan Gauge II, which also reads CAN from the PCM. According to mine, I'm getting 250 or so HP out of a 4.2L V6 w/ a custom tune. For more information, on the Scan Gauge horsepower and PA install, refer to Alex AKA Raptor05121.

I ran to 60 3 times.....
1. 6.45sec
2. 6.73sec
3. 6.69sec
the best I ever did before with Edge canned tunes was 7.78 and 7.66sec.
So whether the new #'s are accurate or not isn't the point but it seems to indicate the truck is performing better with the custom tuning.........that tune was certainly worth the $50
