K24a3 - offset ignition timing offset at idle

Post by Lyle_57IAL »

Good Evening Hondata,

Currently i have a OEM standard K24a3 utilising a Kpro, with bosch 750cc injectors (deadtimes set), 50psi base fuel pressure, walboro 450 fuel pump. Have a strange issue at idle where the ignition tables are specifying 20 degrees... however the ignition timing delivered (through watching the Ignition timing data on the display) is around 1 degree.

Please see attached datalog and map. Multiplexer disabled, VTC table is Zeroed out, Set in open loop, knock sensor disable etc.

Any insight to this behavior would be much appreciated.

Lyle

This ECU uses ignition to control idle so it will fluctuate a lot when it is idling.

Yes but whats in the ignition table... does not match what ignition timing is being delivered.

Yes, it is normal. The ECU uses ignition to control the idle rpm.
