The tunes are adaptive.  You can add/remove timing at all sorts of temperatures.  Build a tune that will run good hot, and you'll be safe when cold (though you can tune in a bit more performance at low temps).

That's the GREAT thing about the EECV

but what exacly is "adaptive".. even when you are dyno tuning, you are not in the same conditions as when you are actually driving it.. even at the same temp.. and i mean the values are set values.. you dont have a table for 10*, then anotehr table for 20* etc.. you know what i mean? im just wondering

what exacly adapts

sorry going off topic..

be aware, fees for getting it shipped here from CFM.. triple gauge pillar cost me more like 125% than the actual cost caus of fees.. id like to know how much for the S/C shipped including everything.. :blink:

Steeda: how much ?

there are many things that allow you to tune spark so it's safe for all conditions:

baseline knock spark table - You set the max spark with no modifiers (20C IAT, and 200 ECT) that the engine can run before experiencing knock

ECT spark modifier - you can add/remove spark at given load values depending on given coolant temps. So when the engine is running hotter, you remove spark... or if it's super cold, you can add spark.

ACT spark modifier - like ECT, you can add/remove spark for given intake air temps at given loads. If it's cooler, you can add spark, if it's hotter, you can remove spark.

Max Spark - this is the maximum amount of spark you will ever run. Just lets't the engine know that regardless of what numbers you come up with there is a maximum amount of spark you can run

spark adder for open loop - when in open loop, running richer fuel means you can run more spark. Add that in here.

max allowed spark on cold start - specify maximum spark for cold starts...

the EECV will grab all the values it needs and come up with a spark required for the current ECT, ACT, and load values. This allows the engine to 'adapt' to many temperature ranges, and why there's no reason to not have a tune work well in cooler weather.
