Is there a difference in tuning an all motor car and a turboed car or is tuning tuning no matter what your set up is ? If so what are the differences.

Yes there is a difference, in fact there is a difference in lets say a high compression, large cam all motor to a stock cam, stock compression tune etc...

The differences are ignition timing, target air fuel ratios (lamda), vtec point etc...

So which one is easier ? what i was wondering is if you can tune an FI motor would you be able to tune the all motor or vise versa or are they just to different.

It is easier to tune an all motor vehicle for the most part...

For example on a B18c:

Do you guys use different ECT and IAT ignition compensation for boost and N/A?

How much timing you normally pull for high ECT and IAT temps generally?

Every car is different

How does one effectively tune for this??

Get everything else tuned and then sit in a parking lot and adjust ECT comps as the engine gradually warms up. Add/Subtract fuel to maintain a steady 14.70 at idle.
