Engine Mapper's Subaru Tuning Guide
I thought I'd put together some of my technical thoughts and opinions into a bit of a guide for those that would like to use it as a reference. Hopefully it will evolve into something even better with input from others, both non technically able and those that are.
Feel free to PM me regarding various topics that you would like covered and perhaps other ideas and feedback.
Engine Mapper's Subaru Tuning Guide V1.1 can be downloaded here
V1.1 includes:
Fuels and additives
Fuel pumps
Injectors
Fuel pressure regulators
Intercoolers
Dump Valves
Exhausts
Spark plugs
Airbox vs induction kits
Suggested typical upgrade routes
What is engine mapping?
Mapping terminology and what it means
Happy tuning!
Graham

Nice easy to read explanation Graham.
I think I have spotted a small omission on page 9 :-
"Firstly if you are sticking with your TMIC, (top mount intercooler),
Exhausts
Exhausts are a fairly simple topic to cover."
There appears to be a section on DVs missing.

'You’ll find that the majority of UK WRXs require 95 RON fuel'
Our UK WRX says SUper Unleaded on the fuel cap. I would sya the majority of UK WRXs require 97RON.

It did have a standard regulator, when it made 330bhp, still have 380's.
I have a Fuelab regulator now, won it at Scooby Shootout a couple of years ago.

Ok fair enough! Well lets not distract from the point that the average is far less than this on 380cc. I'm wary that a lot of customer perception is based on the forum 'best' results. I.e some poor sod having read your statement will now assume his 380cc injectors will do 330bhp no problem.
You catch my drift!
