Well its alright. The more the american's hate these things, the more i can pickup on ebay for the price of a tank of fuel :P

Google: "Yahoo e-manage group" . Download the software and look at it urself. Instead of going off what u read. Ive used these on many cars. Great bang for buck. there is also a program called 'e-supporters' which enables auto-tuning through wideband, mapping of afr, dyno simulation and more.

I cant be bothered screens hotting, but here is a pic off there website. And yes, it does full real-time map trace and all alter-ations are realtime to the ECU. All come as standard. No emulators required :P
