There have been EFI101 courses in Perth before, dont know when they are due to come back. I think TUNA attended the last one, dont know if any other members went.

i found a good basic guide to the WRX ECU on scoobypedia

If you're going to start tuning yourself, get a good digital lean/rich meter. Another handy tool is a G-tech meter. You will also need to get you head around fueling, ignition timing and if tuning a later model, cam timing as well. There are some excellent books available from places like Pitstop Bookshop.
I've found a lot better tune can be achieved than certain "reputable" tuners in town.
The Link I've been involved in tuning now gives far better economy, throttle response, torque and hp.......very noticibly so in all area's.
It's a very satisfying thing to do if you can, but DONT attempt it without educating yourself first.

[QUOTE=foxey]efi101 is very good. Despite what some people may tell you, tuning cars is a science and not a black art. Whilst experience is a good thing and can make you quicker, tuning cars is not a difficult process, they want fuel and spark, give them the right quantities of both and your golden.[/QUOTE]
They actaully need Air, fuel, spark and timing

spark and timing ? crikey! wormholes

Well ive gone out and bought myself a tuning book from the pitstop bookshop titled - Engine Management, Advanced Tuning. and so far (1/4 of the way though) is a great purchase.

the author starts right from the beginning, going through AFR's, Lamda, timing etc but also alludes to alot more detail later on in the book.

ill let you know how the rest of the book is - its my 'bus ride' reading....

Steve

pdf!

Yeah, spark and timing. As far as I know tuning will also not get more air into the engine.....

Matt, I've got the EFI101 training book, you can borrow it/pdf it if you like but I'm far to lazy to do it myself.
