cold start help

Recommended Posts

Hi guys

Attached my ecu file for this car. Which value do I need to increase please:

Problem: On cold start, car starts on first swing, I checked the AFR and it was 16.5 which is VERY lean , but only for like 5-10 seconds, then all of a sudden idles smooth and AFR is at 11.5 which is perfect, so pre-crank, crank enrichment is fine. I tend to believe I need something more or better in post start enrichment or warm up enrichment?

Many thanks in advance

Edit; Perhaps the Post Start enrichment table ?

Has this been tune? Reason i ask is the fuel table scaling is only a small range. 14 min to 32 max.

I would start by using the base map cold start/warm up settings, tune the fuel table then go back to the cold start settings

Hi there !

This car is perfectly tuned yes ( Fuel map ) etc if that is what you are asking. just the cold start Issue, for that 5-10 odd seconds, from there it is 100% fine, almost like a delay or decay setting or something 

I have NO idle control because the the idle valve I have (standard) is not even on the list of available units to choose from ???

The idle valve is configured on aux 3?

A log would be more helpful to confirm what part of the cold start is not correct

Your Post Start Enrichment table looks like it hasn't been configured properly. This table is active right after Crank Enrichment decays and before the Warm Up Enrichment takes over.
