Possible to use operands in MAPs?

[Alvin]

I'm looking up to set up my own custom maps with simple things like +, -, / etc. to manipulate simple things like fuel trims.

Is there anyway to do this without setting up a complete PID?

[Tordne]

Nope. You'll have to create a custom PID the represents the calculation you want to represent. Then that custom PID is used in the MAP.

Darn,

That would make my life very easy. That and a paste -> Multiply by percent.

Do you know where I can find a tutiorial on creating a calculation type PID?

Thanks.

Not that I've seen, but here is an example that might help ya out:


#Units Low High Fmt Expression
#------------ ------------- ------------- ---- --------------------------------------------------------------
*CLC-00-001
%rich -20.00 +20.00 .2 "({SAE.LONGFT1} + {SAE.LONGFT2}) / 2"


#Code PRN SLOT Units System Description
#------------------------- ---- ------------ ---------------- ---------------- ------------------------------------------
CALC.LONGFTAVG F001 CLC-00-001 %rich Fuel "Long Term Fuel Trim Avg Banks 1 & 2"


These go in the sections in the 'calc_pids.txt' file located (by default) in your "My Documents\EFILive\V7\User Configuration" folder.

Thanks that worked like a charm.

quick question? What is the .2? under FMT?

[Tordne]

The .2 is for the precision of the PID (number of decimal places). I like to have 2 DP :)

For some PIDS there are no decimal places, like ECT and IAT temp for example.

Awesome thanks.

Let the games begin!
