Yes, fastegg. I think it's ground breaking, too. I guess it's too technical, or too much work, or too expensive. I'm somewhat disappointed in the lack of interest/lack of comments returned on such breakthrough knowledge.

Yeah me too.. I mean literaly every day there's another device that makes my job easier... As i said, i built and road raced motorcycles for 25 years and all our tuning was guesstimates, 1,000's of plug chops, seat of your pants asking someone else or luck.... or hope !!!!
Now we have a choice of SG2, UG, DashDyno, OT-2, ScanXL Pro, Superchips (flash tuners), and another one i found today the 'inTune' touch screen tuning device. (check out this site, tunertools.com its got heaps of new tech) and about a dozen other sites.. and i find it just so bloody fascinating and happy that there are guys out there, all over the world sitting down working out how to make this stuff work, make it cheap, make it compatible with my car (and everyone elses), make it easy to use, make it realiable... and updatable... all that !!!!!! I reckon its f**ken unreal !!!
The only problem ive got now is deciding which one to get. I like the DashDyno, as it works out HP and torque, its got a GPS for gods sake to calculate the terain your driving on and accurate speedo, ports for O2 sensors and EGT... (go and have a look at its key features at the Autarra site
auterraweb.com/dashdyno.html ... Right now what i really want is super fine fuel consumtion figures... I need a tool that can tell me if i change tire pressures it can tell me, and by how much..... even only a few short years ago, a device that could do this was not even dreamt up yet, and yet here we are, the UG and SG2 might and how cheap are they ??? ... ... ... ... puts a big smile on my face...
I hope i'm not writing too much ?.... A few months back i bought an Autel MS509 code reader/scanner thingy... $70 'cause my girlfriends Peugeot 307 had a DTC light on... its been on for years, weve been charged $75 twice during servicing to turn the light off but it kept coming on so i bought a cheap scanner so I could turn the light off...and it said 'vehicle speed sensor' fault... there is a speed sensor on each wheel but it wouldnt tell me which one, the local Peugeot dealer wouldn't tell me how to check it.... they wouldn't help me one iota...
they just said "bring it in and we'll work on it" GRRRRRRRR
(( so i'll leave the light on.. its not effecting anything.... Now, an unexpected find was on live view it tells me i can only get TP 85% max...(throttle position will only get to 85%...its fly-by-wire so, i wouldn't know what to look at... this would explain why its sooooo slow on hills.... I walked down to my friendly local Peugeot dealer and asked if they'd come accross this and all i recieved was the backs of their heads.... GRRRRRR
(( Now to put that in perspective, ive rung my local Lexus dealer services dept and they couldn't be helpfull enough... They faxed me pages out of the workshop manual.... talked at length about servicing issues and i asked them if they'd have any idea if i could fit paddle shifters.. He said "leave it with me"... 2 days later he rang me back, he had asked some Lexus electrical guru and told me "no problem" blah-blah-blah... faxed me electrical pages out of the Lexus book with surgestions about the several ways to go about it.... "If you have anything you think we could help you with, call us" Its the black and white difference between 2 cultures....
I'd better stop writing.... i can't remember why i started !
