Title: PV warmup enrichment
Post by: Sunny Jim on August 10, 2020, 04:34:28 AM
At the Top of the warmup enrichment scale On my PV it says AFR.
In order to lower the added fuel on the warmup cycle,

Do I increase or decrease
The values?

Decrease. The values shown are how much richer to go from fully warmed up AFR. If your AFR ( lambda) table has 14.4 @ idle, then the Warmup AFR requested depends on the engine temp- @50°, chart has 2.1, so the AFR requested would be 12.3.
