And not getting this output around the ECU can show very difficult to have the 20V to idle in the slightest degree. Most tuners thus, stay away from using the 16V's ECU for The straightforward purpose that It really is gas map is up to now off with the 20V's needs that it could acquire excessive reprogramming to receive it the right way to even ensure it is get started. Thus employing a entire aftermarket unit or OEM for 20V is a lot more cost effective than to test to devise it dependant on the 16V ECU.
