Something isn't right w/ my engine

that's called interpolation. i would be VERY surprised if the OBD2 PCMs didn't do it since ALL OBD1 ECMs/PCMs did.

I figured they would but I really don't like to assume anything. Especially if the answer is easily attainable.

So the loss of resolution really wouldn't be as impacting as one might think. Cool, thanks Rob.

depending on how variable an engine is, you would probably never notice.

if an engine for some reason has a SHITTY VE at 100kPa/2000 RPM, but by 100kPa/2400 it is sucking 100%, then you would have a situation where you would need to compromise, but that's RPM based. kPa is similar, say 50 and 60kPa. if for some reason there was some funky reversion or whatever at 50 kPa, but was gone by 60, then if there was a 55kPa line that could adjust for it.
