This is my Toda A cam with cam gear tuned with Apexi power fc.


This is my Toda B cam with cam gear tuned with Apexi power fc.




I know i can improve between 4000 to 5000rpm with changing the air/fuel ratio. But i have a question. Is it more lean make more power????
When i see the dyno graph as below, I through if i can tune the air/fuel ratio between 13.6-14.2. Is it i can make more power with this setting????

This is another car.




Hope can share with your opinion!!

Looks like you did it right.. wonder if Yahoo! won't let you link out? Try http://www.we-todd-did-racing.com for hosting.

 

Thanks for your help!!
I changed the pics already.

 

what si KW? and what is the conversion to horse power?
oh and anotehr thing...Dynos are Very subjective so do not look at other peoples numbers as a garantee or a measuring stick of what you should be hitting

the curve looks good though

These questions are irrelevant to his question.

If you'd take the time to actually READ, you'd learn that he's not asking for other people's cam gear settings or other similarly useless information.

I would tune the AFR for as lean a ratio as you feel comfortable with. More often than not, you'll find a few more hp when you lean out the mixture.

 

Are you using a wide-band O2 while tuning? What does your current A/F curve look like? Where's the VTEC point set at?
