eCtune

http://www.dynolicious.com/ I just stumbled across this today and I'm curious of what everyone thinks. Could this program be used effectively as a tool to tune timing on the street? Has anyone had the chance to fool around with it yet? Here is a short video that compares results on the dyno and at the track to the numbers from the dynolicious software as well as a G-Tech accelerometer: http://www.dpccars.com/car-videos-08/08 ... G-Tech.htm

now, if they only had the iphone for tmobile...

Hacked iPhones work fine for T-Mobile.

friend of mine had one when they first came out. he had ton of problems with it. it got relocked 2 times before he gave up on it. you can use the ipot touch too, but 299 for the base model.

Has anyone tried to play with the Wii controlers (Wiimote) to get an accelerometer? See at MSDN (Coding4Fun) And the Wiimote itself is relatively cheap to buy.

When they first came out isn't much of a basis for unlocking phones because they just came out. They've come a long ways and there are plenty of people using unlocked ones now.

I'd like to see some more results of this product from other people. I'm still a little skeptical.

Wait... Wiimote... Bluetooth... Laptop... This could work... lol

Would it work with the BlueTooth of my cell phone? (HTC TyTn2 with WM6) It's so tempting to start playing with that!!! Wiimote is able to measure along 2 axis. So it's ideal for acceleration, braking and cornering. But... I have a VSS converter to finish

u can use racechrono: http://www.racechrono.com/ its a free program like dynolicious, only its for a symbian phones, i use it and it worked great...

But that uses GPS which is WAY to inaccurate. GPS only updates once a second. So when you go from 0 to 100km/h in 10 seconds, it can also be 11 seconds or 9 seconds. Error: 10%

unless your paying big bux for a GPS your only accurate within 30Ft or so; If you buy the wholy moly expensive equipment like our survey equipment, you can get accurate within .005\" but that's only at a fixed location when the GPS has enough time to lock into it's position that precisely.

And do a lot of averaging, which takes looooong.

I got some freescale accelerometer chips (the older high sensitivity/5vdc kind) that I've been wanting to use with my SSI-4. Basicly it only needs a 5vdc input, ground, and output signal. A few caps/resistors help it read better, otherwise they're 1/3 the size of a eeprom chip. With no pull on the axis in question, it reads like 2.5 olts, 1g = 3.7v, -1g = 1.3 volts. The newer are less volts/G. The best part is the pricing is the same as their MAP sensors, at least per 1000 units. I never got around to testing them, since its been 1 thing after another. I'm still not 'done' with my car, lots of ideas to make into reality. edit: They still have the 5vdc at digikey for $11.51 ea, MMA1260EG-ND. IIRC they stopped production last summer, and the new units are 3.3vdc input.

Symbian ??? I can't believe I didn't see this post earlier... *visiting link*
