Ecutek Ignition Correction?
 

There seems to be some new things being logged in the latest Racerom update. Question on the new parameters I'm not sure I know what these are doing.


Ignition correction course and Ignition correction fine. Pi duty? Cps voltage?

These have been about for a while.


PI Duty - Duty cycle of the port injectors
CPS Voltage - I think this is the carbon canister voltage, re-used for EBCS/O2 sensor etc. If you've not got any new external inputs, ignore/stop logging this.
Course IC - The advance map - this will show advance map x IAM
Fine IC - This is FLKC and will show you where timing is pulled or even, if your IAM is less than 1, you can see where it is putting timing back in.


You can now stop logging Knock Correction Learn as the Fine and course replace them and are more accurate.

Yes, the Ignition Correction Course and Ignition Correction Fine are part of the knock control system.

The Ignition Correction Course reports the requested dynamic ignition advance from the ignition advance map after any correction by the Advance Multiplier (ignition advance value x Advance Multiplier).

The Ignition Correction Fine is a compensation to the Ignition Correction Course based on noise detected by the knock sensor, or lack of noise (Ignition Correction Course +/- Ignition Correction Fine = applied dynamic ignition advance).

PI Duty indicates the duty cycle of the port injectors. This is an indicator of how hard the injectors are working to deliver the amount of fuel requested. The injectors reach a theoretical limit at 100% duty cycle, although you would never want to run your injectors at 100% duty.

CPS voltage is the carbon canister purge voltage and is one of a few inputs you can repurpose for an ethanol content analyzer, wideband o2 sensor, etc.

Bob excellent response. The one you sent me in email was even more explained. You rock sir
