AEM Cam gears

Skunk 2 IM
DC Sport 4-1
Head was milled a bit .
Pr3 pistons.

lsd tranny : JDM y1


compression is about 11.7:1

engine is in a 2nd gen integra. using stock b18a injector running of a b16 ecu "pr3"

i know this question has been asked many times but i know lots of you have close to the same setup.

i need your help with the vafc. what settings should i do.

when should i engage vtec? hi and lo. , where shoul i increase fuel.

engine now has 2000kms, and i dont want to drive around for another month without doing some sort of adjustement... also what should the cam gears be on?

All your help is greatly appreciated.

i would advance the intake 1, retard the exhaust 1, put the VTEC at 5100-5200.. just try different points and see what's better...
chances are with the pr3 ecu you are running a little lean.. maybe add 5% fuel at WOT anywhere above 5k??

no way to tell really.. but the majority of engines i've seen dynoed usually need some fuel at wot during high revs

 

When you say WOT, do i add 5% at the Hvt settings or the Lvt settings?

 

Do you guys think that the stock pr3 ecu is doing the job, or shoudl i get it chipped to Type R specs.

please advise..
