how rich/lean should i set my programmer...? any suggestions
i have played with it and it seemed faster with it turned somewhat lean...

 

Mine runs better being set richer, still testing this diablo. p.s. Nobody will talk to you about a handheld on this site.

 

yeah i figured no one would talk about diablo... everyone else does the custom tune stuff...

i have been messing around with mine lately trying to get the right air/fuel ratio down... i have gotten better runs out with it running 10% lean and advance the timing about 12%... i know that the predator can only change 1-3 points on the air/fuel ratio... im still playing but i really need a gauge so i can see where i am at or if im even close to the 14.7:1 air/fuel....

what engine do you have?... mods...

i have one. didn't see the post till now. no need to flame on the handheld. to me its the best handheld you can get. just not as good as a real tune.

as far as the settings go. i really can't remember where mine where. i have been running a johan tune for almost a year. and it's pig rich right now. best bet is to tune with it slowly...test, tune again.

not to be a dick, but if you do a search on predator settings, you will find a ton of info. 2 years ago that was the rage before all the mail order tunes and stuff.
