A way to log RPM error?

[Highlander]

Is there a PID for this? I guess there is.. This is for LS1s

I am thinking of making a Calc PID with my preset idle rpm.

[mr.prick]

For {B4603}?
{preset idle rpm}/{SAE.RPM}) = percentage difference
{preset idle rpm}-{SAE.RPM}) = RPM difference
Maybe a "commanded RPM" with lookup function
Lookup {SAE.ECT.F}, 133,950, 154,900, 176,900, ect.

Nevermind.. I found the pids necessary to do this...

[Highlander]

Way to do it is:
{SAE.RPM}-{GM.IDLEDES}

I believe that should work... What i need to know now is the absolute function

[mr.prick]

What table is this for and what will it do?

[Highlander]

RPM 0.00 500 .0 "iff({SAE.RPM}-{GM.IDLEDES}<0,-{SAE.RPM}-{GM.IDLEDES},{SAE.RPM}-{GM.IDLEDES})"

[Highlander]

This is for dealing with the absolute RPM error idle tables...

I just want to get this DEAD on with my pops Z06 as it has a hugely ported throttle body and the slightest changes in conditions will cause it to just stall under varying conditions. There is no room for error on this one... Not like the others...

[mr.prick]

ETC only?

[Highlander]

Yes sir...

This is the PID.. and it's working flawlessly

*CLC-00-002
rpm 0.00 500 .0 "iff({SAE.RPM}-{GM.IDLEDES}<0,{GM.IDLEDES}-{SAE.RPM},{SAE.RPM}-{GM.IDLEDES})"
