mspnp95 base timing set, idle still bad, change fuel table?
So we just now got the base timing set in megatune and we're still experiencing an idle that jumps around and is in the 11 afr range. I think we set the req_fuel correct, the number shows 6.5 I think. Under the calculator we input 1850cc as the engine size (bored .30 over) and 550 as the injector size as we're running rx7 550's. For the desired afr we input 12.7. Does this all sound correct?
Since it's so rich and seems to be somewhat misfiring, do I just need to tune the fuel table to get it closer to 14.7? Or what is my next step? Also, the fuel in the car is questionable (old) can that be making this big difference?)
Sorry if this is searchable, I tried my best. Help the N00bFam out please?

Something odd I just noticed while reading a how-to manual. The manual http://www.megamanual.com/v22manual/mtune.htm#constants here says that all v2 units are 250kpa map sensors. Our value was set to 400kpa for some reason?

Any chance someone with a turbo miata running 550cc injectors could post the VE table that they're running. We have the Begi Shanghai kit with the 2554 turbo. Not super sure where our values are supposed to be in the table, but the base map numbers seem to put us in a super rich situation.
I just generated a VE table based on table generator on the MS. Going to see what that puts me at.
