Tuning S2000

[Kieranrob]

Has anyone done any tuning to there S2000's on this forum?

So far I've changed the exhaust including the cat and the manifold, i had to fit a engine torque damper to stop the new manifold touching the steering rack but that was it! The air filter went too and now I've got a AEM v2 fitted instead.

I then thought i would get a tune up and a AEM ECU fitted at the same time by mase engineering when he was over from the states but that turned out to be a complete waste of money!

less than 24hrs later my car wouldn't start and i had to put my old ecu back on to get her going again.
To cut a long story short and after talking to a few tuners this is not the 1st time this has happened after mase has got his hands on them. Turns out there's no way you can properly tune a car in 1hr which he did on mine it can only end in tears!
you try getting your money back of someone that's lives thousands of miles away more chance of getting blood out a stone!

That's st news about your ECU!! Hopefully you will find someone better to do it next time? So have you noticed that the drone is still there with you changing to headers and the cat? Am holding on to my exhaust for just now because I might buy headers for it at some point if I can find something second hand on ebay?

What else have you got planned for tuning?? I was looking at the superchargers but I would preffer to stay NA with this car.

Hope you don't mind me jacking your thread, but it seems silly creating a new one.

Can anyone recommend a stainless steel aftermarket exhaust, cat back? I feel the current exhaust note is missing something and want a nice fruity one.

I don't want to get one shipped over from the States, so links would be nice

I done a fair amount of research on aftermarket exhausts for the S2000 last year and the best two that I thought were good value for money and that gave you that fruity rasp was the HKS High power dual or the Tanabe concept G. I went for the Tanabe concept G on the AP1 S2000 and it looks and sounds great like I said I will post some pictures later on this week. It cost me around 800 quid from a UK supplier and the HKS high power exhaust can be found on ebay.

I was also looking at the SPOON N1 and the MUGEN exhaust but they are more expensive and the SPOON N1 is really loud your ears will be bleeding after a few hours

Cant see myself doing much more to it to be honest, i did look at the superchargers as well but i like the car the way it is.

CAI, manifold, 70mm straight through exhaust, 4.77 final drive and one of those pre-tuned ECU from Spoon, ASM, MUgen et al.

The AEM is a waste of money for NA application IMO

What is the standard drive ratio?

Where can the updated ratios be bought? I assume it's just a different crown and pinion rather than an entire new diff?

I went from 3.23 to 3.64 on my M3 and it made a huge difference, 14% more torque at the wheels. It's easily the best way to improve acceleration on a naturally aspirated car, forget exhausts, intakes etc. Besides the S2000 has plenty of revs, so the car wouldn't run out of revs too quickly

MASE tuned my supercharged car with 4 different set ups (10 & 12 psi 95 & 98 RON) I had no issues with it over 20k miles.
The F20C is notoriously difficult to tune NA as Honda did such a good job of it. Some have got gains but they are expensive IME of trying on 3 cars not worth it. FI is the best way forward.
BTW mine topped 420 BHP at 12 psi with 98 RON
