If anyone would like to look at this datalog of a 4th gear pull, and the tune that it is currently on, I would appreciate it.

Engine setup: Highcomp B20 vtec with GSR head, GSR cams, GSR intake manifold, stock exhaust manifold, 2.5" header back exhaust, 3" generic intake tube with ktunded velocity stack and filter. Injectors are freshly cleaned and flow tested.

With Key on and engine off, my map is reading -3.1. Now we are at 3200feet of elevation. But, that being said, under WOT i can only get into cell 7 and 8. And those ignition tables are much more advanced then 9 and 10.

the map is affected based on your location .i can is 2 deg as long as you don't have any issues (Knock)

you are ok your spark plug is your guide.

I suggest you may modify the load and rpm index to capture more point since you set point for vtec is 4900 .

good luck.

definitely seeing some speckles on the spark plugs. Only have 91 octane here too.

What do you mean by modifying the load and rpm index? how do I do that? What are the benefits?

Hi
what normally I do at high speed (vtec) change the RPM index starts from 4600 any point below that is waste and you will not use. then increases by 200 rpm the benefits are captured more points and apply the change as needed, in your file it shows 500rpm that gives you 9 point to adjust only. (4900-8000) your rev set @7812.
