MAF & base fuel tables

[Knowlden and/or Eller]

Bruce, I found the fuel tables in the bin you sent me, right around 42d,
they jump right out at you. My bin, like yours, maps pretty close to
ecmguy's '86 vette listing. Mine is good right up to the fuel table but then
the data (that would be the fuel tables) directly maps to the tables
following, closed loop qualifiers. There are some MAF tables right at the
end of the calibration (just before the serial data and code) that may
perform a similar function. My bin has them but I haven't had a chance to
check yours.

Regards,

Bob

Hi Bob,

Yes, I also have the Bosch (modified) MAF unit. GM changed the code between
87 and 89. I am not sure what was changed.

I am also skilled in Promedit operations. This is a great program.

As far as I know, there is a base fuel map in my BIN files. Maybe tonight I
will have some time to look up the address and send it to you.'

Best Regards,

Bruce
