ecu fuel trim

[totta Crolla]

Ok it's a Freedom ecu
Direct fuel I think and my particular Freedom does not use target AFR
which does make getting a fuel map even close somewhat of a challenge.
It does have a basic learning function that will get it to approx. 14.7 AFR
but that gets a little scary beyond 6000rpm under load.

I'm using TPS vs RPM with an Innovate LM2 AFR meter and it is fairly
easy when data logged to see where fuel needs to be added or removed
on the map.
