I know some cars you an get performance chips for them that just basically piggy back the ecu, is there any decent/reliable ones for the s2000 that actually do something? If not any suggestions to decent power gaining mods? Only wanna gain 10-20whp not heaps which I'm aware is extremely difficult without turbo/supercharger

As in something like this?

 

there are no performance "chips" for the S...and if you run hondata, youd have to get the K-series version and change a bunch of sensors for it to work...your best bet for 10whp to 20whp gain would be simple bolt ons and then something like AEM EMS or Haltech...but its pretty expensive for little gains

 

If you have an 06+ AP2 you can get Hondata Flashpro.

Otherwise your options are stated above. Or you can get a few bolts ons and a simple VAFC2 to help lean out rich conditions.

 

what bolt ons are recommended? Taking the CAT off is a huge boost IMO..at least for me it was..

 

Cat delete will be by far best bang per buck, followed by a decent air intake. After that, you get into the money zone where a tune (and therefor stand alone or plug and play ecu) is required to maximize power on non-dbw NA cars.

 

the order i would do it in is test pipe, intake, exhaust, header, tune with a stand alone

 

Hardly worth the work for 10-20hp. You're better to get faster by learning to drive better.

 

If you just want quicker acceleration get 4.77 gears.
