Fuel systems questions...

[MZsS2000]

I'm new to the S2000s and I have a 03 with a AEM V2 CAI and I ordered a Invidia exhaust and test pipe also DC Sports ceramic header....Will the stock computer be able to adjust for these modifications or will I need to upgrade the fuel system in some way?

Yes, the stock ECU will work fine with these modifications, but just wanted to give you two little bits of information.

1. On the test pipe, make sure it has a CEL fix. This can either be something soldered onto the O2 sensor's connection wires, or just a metal extension where you screw in the O2 sensor to the pipe. If the O2 sensor throws a Check Engine Light, you are actually hurting performance and fuel economy.

2. The DC Sports header has consistently shown over several completely seperate dyno tests to effectively reduce horsepower output on the F20C motor.

I have been looking around for a decent header for awhile now which header does best with the F20c motor.

P.S. Thanks Scott

The best header's are all big money.

Companies like Mugen, Toda, Fujitsubo, Rick's all make good headers. But you can expect to pay over $1000 for a new one, and at least $750 for a used one. Megan Racing's header seems decent for the price (about $400), but I haven't seen all that much data on it, and Megan's quality in the past has been hit-or-miss on a lot of their products.

Hey guys I just installed my test pipe with the stock exhaust and and threw a check engine light after a couple of minutes. Do they make a O2 replicator or something along those lines to get rid of the CEL?
