Lambda and Cold Start

A little work on the cold start and various other ECU settings.
The car has always needed a little blip on the accelerator just after starting to keep it running, finally go around to playing with the cold start settings and resolving that.

I'm going to get it re-mapped at some point fully. in the interim the following improves idle and cold start.

The ECU Page is updated with current settings.

Areas of note

Lambda

The Lambda input is now setup so it doesn't just run against its +-10% stops all the time - it actually tweaks fueling according to the sensor input. Combination of:
  • Stock Emerald settings on the lambda curve
  • Tweaking the lambda gain control & update frequency to avoid overshooting fuelling


Cold Start

Larger initial prime leaving the enrichment on for 15 turns and some across the board tweaks for the higher water temperature re-starts.

Full setup so Emissions tests are easier is pending a full re-tune, theres just no way to do it myself without exhaust gas measuring equipment.
