98 Octane fuel is readily available in the UK so that shouldn't be a problem.

J's Racing have offered a core exchange.

I would go for the VAFC II but with my limited knowledge I'd still be making stabs in the dark.

Thanks for the advice though :thumbup:

Amuse Boy:
read my mods in my sig:
before the Mugen ECU I was running as RICH as stock!
once the ECU went in.. now my car runs PERFECT!!!
Mugen ecu IS a JDM ECU. King's sells it and Mugen does NOT make a different ECU for JDM vs other markets.. required MIN octane is 92 in usa
fuel in Europe is at least 95 by our standards
with the mods you have, a Mugen ECU will do wonders, as Im sure the J's will.
you will NOT run too lean, remember the stock ECU runs rather rich. Just remember regardless of the ECU you choose, you must at least run a cooler fan switch and thermostat, and Mugen also suggests the radiator cap.
I was in bumper to bumper traffic leaving Toronto last week on the 401, for 2 hours.. NOT 1 problem. The other good thing is the Mugen ECU is no were as heat sensitive as the stock, so it reduces the bogging you experienced, I am sure the J's will do the same
defiantely add a test pipe also, will reduce 15 pounds 6kg?? and flow better
HTH's

Marco - I already have the Mugen cooling mods installed. :)

I think I will probably go for the J's racing ECU but I am not sure if I want to remove the cat...

What plugs are you using with your setup?

Thanks

I didn't notice you were in Europe! THATS what those flags are for (DOH)

Then yeah, with the exchange and the octane not being a problem, I'm sure it would work for you!

Stock plugs 41000 miles currently, had 35000 when i installed the ECU, I do not think changing plugs will matter at all with the mods you have and are planning.
You do not have to use a test pipe, But since both ECU's disable the secondary O2 sensor..why not?? Might as well take advantage of all that you are paying for.

With those mods, there is not need at all for an ECU. For one, all your mods haven't opened up your breathing as much as you think (proof, ask anyone, all those mods add up to maybe 10whp).

Remember, There are numerous owners running stock ECUs with Comptech and Vortech Superchargers. Your car is running fine, don't waste the money.

Are you sure about that? The J's alond add around 12whp in the mid range.

Still confused...

If someone dynoed the J's Racing Header alone and got 12whp I def. need one. :LOL:

AB dont waste your money on a EMS "unless" you plan on doing alot more tuning in the future(like me :D )!

You will be fine on the stock ecu "but" if you are really intent on getting something then all you honestly need is either a V-AFC or at the most a Greddy e-mannage.

In regards to tuning and mapping Dan Turner @ Jakan is excellent with most EMS's he used to work for the Mugen race team so knows hondas fullstop! (they are closing down but I'm sure if you called him he would still sort you out :thumbup:

Andy

Thanks Andy! :)

It's looking like I will be going for a J's Racing ECU mapped to the mods I've got. A decat pipe and some cooler plugs.

Don't know much about the decat - do I just screw the 02 sensor into it?
