I went to a local tunner and he suggested I do 2 hrs street tunning
and 2 hrs dyno tunning

how important is street tunning?

 

... a better term for street tuning would be tuning partial throttle... basically, you need to tune for partial throttle since this is where you spend most of the time driving... how often to work/school/store are you at wide open throttle like on a dyno?... so tuning for partial throttle is just as important as dyno tuning IMHO...

... also, here's what hondata says : http://hondata.com/techwidebandtuning.html

... hope this helps... late...

I would say street tuning is MORE important than dyno tuning. Spend the majority of your time on the street fine tuning your car. Once the street tuning is complete the dyno should only take an hour or two (tops). The dyno does not simulate real world driving (i.e. intercooler effectiveness, real load, etc). Adjustments made on the dyno should be very minimal, mostly dealing with your timing and vtec (if you have it) crossover point.

 

Agreed on both counts, and fuel economy can be had this way. That means $$$

 

I guess they would use a o2 wideband on the streets?
what is done during street tunning

 

... tuning air fuel ratio for either power or fuel economy... i am not sure on the ratios (someone help out)... but tuning to a particular ratio will yield you more power... and tuning to a different ratio will give you the best fuel economy... it depends on what you wanna do...
