cwtt Posted December 14, 2023 Report Share Posted December 14, 2023 What would cause a negative warmup enrichment value? The car is completely warm, and the enrichments are all "0"? ECT-188f 0% warmup enrichment: Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 14, 2023 Report Share Posted December 14, 2023 That runtime comes directly from the warm-up enrichment table or if you are using multi-fuel mode it will be a blend of the two tables. Do you have multifuel mode enabled? Are you sure that is the map that was running in the ecu at the time that log was recorded? Quote Link to comment Share on other sites More sharing options...

I didn't realize there were 2 separate warm up enrichment tables for flex fuel. Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 14, 2023 Report Share Posted December 14, 2023 It doesnt have to be, you can set it to single mode or multifuel mode. In single mode you can use a 3D table with ECT Vs Eth% which is less tuning and will work sweet for start up and idle etc but possibly wont drive as nice if you do drive while the engine is still cold. If it needs to drive nice both warm and cold then the two blended tables with TPS on the axis would prob give a better result but will take a lot more cold starts over a period of weeks to tune.
