Say you have a car that you are intending on tuning with Hondata and you are planning to also change the injectors. Say also that the car in its existing form (utilizing stock injectors and a FPR) already makes good power (196 whp) and has been tuned already....

Before tuning - would you zero the cams on the cam gears, retard the ignition timing to stock, reduce fuel pressure etc? Or would you leave all that and just tune the Hondata to the existing setup - and then following Hondata setup - then tune the car on a dyno adjusting all the cam gears etc.

PB - who is not sure which comes first, the chicken or the egg.

 

I'd leave the cam gears alone and tune the car so it runs decently enough to get around until you dyno.

 

The car is going to be tuned with a wideband 02 in the tailpipe first - so we can tune partial throttle on the go. I'm not worried about it being able to run - but I guess my question is will cam gear timing already optimized for the current conditions - will it change significantly with increased fuel? Or does it (cam timing) represent a "sweet spot" of the cams?

 

I always thought you did cam gears first, then fuel etc, since once the cam gears are set for max power, other variables wont change the cam gear setting

rob- once again waiting to be corrected

 

I'd say the current settings are fairly close, if not dead on.

But then again, each motor is different and there's always the oddball motor that wants to make more power with seemingly odd settings.

Just play with everything (cam gears, fpr, hondata) when you get to the dyno and see what your motor likes.
