That's the one Tone, that's actually the old one there's a newer one out as well but there all the same inside. If you want instructions send us an email and I'll send them out lads.
With a CT9 on 0.9 bar you don't really need one, the stock ECU will be fine. Run 1.1 bar I would imagine setting two would be more than enough, probably setting one then fine tune with GCC.
In basic you want to test the car on setting one, if the EGT temps go up and over 850degreres (probe in manifold) then slow down and change to setting two. Keep doing this until your on the right setting with constant EGT readings of 750 - 800 degrees. Then ldrive for a few days, then dyno with GCC and off you go. I drove without a GCC for over a year although the tune is basic.
To set as an example we ran 202@ wheels with Blitz K1, 1.4 bar, 550cc Injectors on setting 4 I think it was bearing in mind this was years ago although I'm pretty experienced with the units.
Best Regards,
Toby
