standard MAT/TPS fuel enrichment table.

The default config for fw1.2.15 gives a MAT/TPS Fuel Enrichment table where
(TPS%,MAT°C) FE%
(0,20) 100   which is alright
(0,60)  94   Which is very surprising for me since I have recorded and analysed data (mean standard deviation etc) which shows clearly that AFR is leaner in this case, hence, in m y config I put
(0,60)106   and I do not need idle ego correction

The actual intake air temperature is a colder when you are "hot idleing", hence the need for enrichment.

This is heat-soak of the sensor, and the  table is  used to compensate for that at TPS = 0%

I totally agree, and to get enrichment we need some value > 100 % not < 100 %?
I saw some other configs also with value greater than 100% for enrichment.

So what do people think?
