Cobb vs UpRev

t-ray

Sorry, I was talking about the Pro. I didn't name it explicitly because I haven't paid attention to the various package names available.

I've wanted Cipher for a long time now; I just can't justify spending $400 for data logging. However, with it, I could street tune my current ride(I presently have a utec). That sounds really cool and would be an awesome learning experience. Plus, there's all kinds of little things I've wanted to log.

For example, I would like to log acceleration times in from say 40mph to 120mph in 4th gear. That would give me a fairly large area of rpm, in a sufficiently long gear. Then run the same rpm range in 3rd gear. 3rd gear is approximately 27% shorter than 4th gear. Then do something similar in 5th. 5th gear is about 27% taller than 4th. It would be interesting to plot acceleration in 3rd, 4th, and 5th against gear ratios.

Once one obtained a large enough sample set, one could start playing with final drive numbers, either through the FD ratio, or tire sizes, and make some decently educated guesses on how changes affected acceleration.

Also, I believe(but don't know for sure) Cipher can log the pitch and yaw sensors used by VDC. It would be interesting(purely as an academic exercise) to measure pitch and yaw on the car over a known section of road as you change suspension components or tire compounds.

As you can see, I would prefer the UpRev solution. There's all kinds of neat scientific/geeky things one can learn from its data logging capabilities. But I have the benefit of having an older platform where the product is available. If I owned a 370z at this moment, I would get the Cobb.
