Very mush if leave it to these guys.
AB how are they going to support you from the other side of the world when you have a problem!
IMHO you need to find a UK tuning house with a dyno and expertise in the S to actually run the tests on the car tweak it according to the results. This is the best way to get optimum results.

 

Okay - finally ordered:

Denso Iridium IK24 spark plugs
J's Racing straight pipe
J's Racing N1 ECU

Some useful answers from J's Racing:

What is the VTEC rpm point with J's ECU?
On the map it should be 5,450rpm. But genuine mater have a margin of error depending on the status of use. So it sometime doesn't display like that. If such is the case, please be forewarned.

Is the knock sensor cut?
The knock sensor is not cut. We think knock sensor is absolutely essential for the street user. The genuine knock sensor is very sensitive to the changes in setting and it delays the beginning of ignition fire. If it delayed 10 degree, it down the power lots. Then it decreases by half for the advantage of exchanging the ECU. We change the MAP of ECU and decreases the level of lag of the tide 3 degree.

What fuel should I use?
We recommend High octane, octane rating 100.

And his comments are:
The middle range torque of your current S has powered up because of J's manifold, so if you don't change the MAP, it doesn't have enough safe margin, we think. Therefore, if you change the MAP, you can get safe margin. It has your all range of torque and power improved.

 

keep us updated AB

 

how muh bhp do you thing your pushing out of your car amuse, with all them mods u have to be gainin round 20+

 

This is interesting since am going to the J's route all the way around. Had some info from J's Racing Japan as well and this is great additional info for me Amuse Boy.

 

Have you had a rerun yet against the S3 AB, now you got all the goodies installed?

 

S2k Crazy - haven't had a chance to get the car dyno'd but it really doesn't matter to me - not into power figures and bragging rights. The main thing is that the car is functioning the way I want it to.

Energetic - nice one - you won't be dissapointed.

TM - not had a chance to go up against the S3 as the guy has a just a had a knee op. BUT I had a few runs with my mates E46 M3 and the results were as expected. From a roll, I get an instance jump and then we stay the same until very high triple digits. From a standing start, the M3 grabs a car length and then this gap stays the same until triple digits.

The car is a lot stronger throughout the rev range, however I have had to readjust my driving style to suit the power delivery.

I know have to relearn the car once again as I have changed to a new set of 17" alloys with semi slick racing tyres. - Photos soon

 

S3's mmmm my last car

I am also suprised that you destroyed it from a standing start. Your mate needs to spool the turbo before dropping the clutch - its then quite a violent start. He just needs to slip the clutch slightly. Even in the wet with 5k rpm from the lights with the ESP off there was virtually no wheelspin - its great fun

In my old S3 I am 100% that I would murder any stock S2000 to 40mph, after that it would be close. The S3 is only .5 second slower on the 1/4 mile. The S3 is really poor above 70-80mph compared to the S2000, and thats when the S2000 really flies. I used to get hauled in at 70-100mph by my mates CTR (not quite stock).

I think a chipped S3 would be close as it seems to have the power above 70mph, but I think the S2000 will still clinch it.

 

Why?

 

Because the car is too slow? The S feels like it has half the power outside VTEC.
