Tuning Notes

This is a very strong engine. It is one of the best V6s we have tested.


The reflash has been tested with an Injen intake and works well. This combination gives 15 lb-ft tq and 13hp. The Hondata reflash will work with any well designed intake.

The Hondata reflash will also work well with any exhaust system modifications.

Can I use this reflash with high octane fuel?

Yes. Although this  reflash was tuned with regular gasoline, using a higher octane fuel will increase the power and torque. The reflash works very well with low or high octane fuel.
