Logging Throttle cracker table and Logging to diagnose a missfire

[z28ls1818]

Throttle Cracker - Is there a custom PID and MAP that has been made or that can be made to log what is the desired airflow for the cracker table? (just like the RAFPN AND RAFIG PIDS)?



Missfire logging -

What Pids do i love to diagnose a missfire. Im getting a misfire while driving in the low to mid rpm range. Car runs great power wise. Let me know what I should do thanks.

Misfire:

- first, do a CASE relearn.

- then, log the pids MFCYL1,2,3,4,5,6,7,8 to see which cylinders the PCM thinks are misfiring.

- are you sure compression is good on all cylinders....?

- are you sure there are no internal coolant leaks...?

- are you sure ignition components are good/firing...?

- are you sure injectors are good/firing...?

No. Cracker & follower are more a drivability based table and do not utilise trims. (which is what rafig & rafpn use to dial in desired airflow)
Too much TC & you can have that annoying "cam surge" at lower RPM/ throttle positions and/or a cruise control effect when lifting the throttle. Too little & you will have excessive engine braking when lifting the throttle.(Some like this)
TF airflow I use to help smooth out small throttle changes & also prevent the throttle from effectively "snapping shut" on a full lift of the throttle, which can cause all sorts of stalling issues.
