where to find a B20b rom to make a basemap?
 
i have been searching for awhile but have had no luck. i am looking for a basemap for a non vtec crv with boost. or just an idea what to start with.

Crome or UD?

Just start with a stock LS in Crome and use the multilpier to adjust from 1834cc to like 2000cc (or whatever a B20 is)

that's it? wow that sounds pretty easy. then do i just copy and paste the values into a p30 rom so i can use the boost tools? another stupid question, how much fuel should i add to the map to make it safe for boost until i have time to tune it for him? is there a general area that you add it to or do you apply it to the whole rom?

Well, you cant totally copy and paste into a P30 rom...you would have to change the scalers (map and rpm) to match as closesly as possible and then copy paste and interpolate in areas perhaps.

As far as boost, use the multiplier again to adjust for displacement and injector and then use the boost efficiency and retard functions in Crome to set it up.

My experience is that if you follow that to a "T" Crome maps tend to be lean overall...so I would richen up the whole map 6-10% to be safe...and then tune right away.

I normally start with LS basemap and yank 15% fuel out over 4500 rpms.

No lie - ask JalopySiR from HT. He made 206 whp at 6 psi on B20B with minor AFC tweakage on one of my MAPhack .bins for OBD0 PR4.
