WOW awesome information I've just spent the last 5 hours on the internet doing research on DIY tuning and stuff.
Can this guide include where you/I can get a Calum RT daughterboard/ECU or even schematics from? If he doesn't mind I can even make my own (well try, I'm pretty good with PCB's and I know a few people who have access to etching machines).
Oh and also installation?
Thanks a million
