tuning lambda in neutral?

[Honda_TypeS_10]

Is it okay to check lambda values to adjust accordingly when my car is in my garage in neutral and revving to the specified RPMs or is this a BAD idea?

That is not a good way of testing. It should be done while driving under laod or on the dyno.

Hi Spunkster,
Thanks for the fast response.

I have a 2010 Civic Si running a MAP tune. For dialing in fuel LOW and fuel HIGH, can I start off by disabling VTEC for the fuel LOW and drive around the block to change the lambdas? Is that the correct way?

Thanks again.

Yes, you can do that.

Yes, you can do that.

Thank you, I will do that!
