Adjusting Air/Fuel Ratio

Could someone give me some insight on how to tune this? I think my car is running a bit rich.

Haha tuning is a little more difficult than anyone would like to explain to you in a thread, take it to a professional tuner.

Hah thanks for the heads up. Well that aside could you tell me what would cause my car to run rich besides a bad tune?

Re: Adjusting Air/Fuel Ratio

As said they run factory rich. You can't tune the stock ECU, so before you tune, you either need to replace it (Hondata or eqiv) or run a piggyback ECU (Greddy eManage Ultimate or equiv).

Re: Adjusting Air/Fuel Ratio

Well I'm having this little starting problem, which is causing my engine to flood. So either my spark isn't strong enough or I'm getting too rich of fuel to ignite probably. I'm not throwing any codes so I figured it wouldn't be a senor.

Re: Adjusting Air/Fuel Ratio

Is your car starting at all? I believe that's a good place to start. If not it could be a variety of different problems.
