So how much are the wings actually worth in terms of corning/braking Gs? Will my data logger w/ +/- 2G accelerometers still work or do I need to upgrade?

That's a very unusual G number for an accelerometer, for race car. Typically they are 5g meters.
You may be Ok at some tracks, but at most of them you will have some places that will put you out of range with the meter spiking above two G.
I have run F2000 cars at Sebring and seen 2 g + in cornering in a couple of the corners there. Bumps will amplify the G's. You might be OK at Moroso however. Atlanta, you will be over...
The long G will be ok, however even on the steepest downhills (with gravity adding braking g) you probably won't see 2...

With the CDS Co-Pilot 2 data and an aggressive driver, i.e. fearless....I have seen 2.3 to 2.4 lateral gs in the FE on many corners during data review. At our level where we don't have access to wind tunnel testing I "assume" the only way to really determine the answer to the question would be to run the car with and without wings under identical conditions of track, tires, weight, etc. Any other thoughts on that?

Very hard to get "identical", even from session to session. So even just adjusting the wing should provide as much evidence. I did adjust my rear wing last time out and it helped. (added 1 click and the rear was definitely more stable.) too bad i didn't look at the top speed which theoretically should have gone down?
everyone seems to run full front wing so no adjustment to make there (like who's gonna give back some front wing??!)
reminds me of the "adjustable" front sway bar which is adjustable in name only.
OK thanks guys... time to break out the soldering iron and see if I can replace the accelerometer chip without destroying it. I have a Race-Technology DL-1 from my autocross days. At the time +/- 2G seemed like enough, so I didn't get the +/-10G option, which _seems_ to just use an ADXL210 in place of an ADXL202.

i just thought of something. with shock sensors you should be able to measure downforce.
Cornering/Braking Gs?
