BTW, don't depend on the fuel suggestions. They are pretty helpful at full throttle if the datalog is done "right", but are pretty sucky for part throttle tuning. The part throttle suggestions can sometimes say that you need to add 10% when you really need to subtract 2%.

 

[QUOTE=gernby,Mar 17 2010, 01:45 PM] The software does allow you to set your desired air / fuel ratios, and will use the datalogs to make suggested fuel adjustments by RPM and load.

 

FlashPro Manager does highlight the cells that you've already modified, but you can still accidentally apply the same adjustment twice if you're not careful. Unfortunately, Hondata didn't give a "apply suggestions" button, so you have to manually apply the suggestions to the tables.

Hondata hasn't shared their algorithm for determining the suggested fuel adjustments. I assume that they average all AF values for each RPM / load, and calculate a suggested value from that.

My preference is to do a few WOT pulls to make sure the engine is fully warmed up, then datalog 1 WOT pull by itself. Part throttle datalogs are much more tricky if you want the fuel suggestions to be valid.

That said, if you want to part throttle tuning, I suggest paying someone else to do it, like EliteTuning. It would take hundreds of hours to learn everything you need to know to get a good part throttle tune.
