I see your point however, it was more a question of well, sure its faster in theory but is it something that is measurable? That I do not know.

measurable absolutely, necessary though is relative. With a fixed sampling rate, the fewer samples you request the sooner each sample will be updated.

So lets say I can only give you 1 sample per second, and you are asking me for 5 different samples. That means you will only get an update per sample every 5 seconds. Now if you reduce that to 4 different things that means you will get an updated sample every 4 seconds. The sampling speed doesn't change, but how quickly you get updated samples does based on the total amount of different samples you are asking for.

Just connect the wires from the 4 pin connector to the rear O2. The wideband will be powered by the MPI circuit which means it wont die while cranking, plus you can log on Evoscan easily without havinng extra wires or adapters. Win win situation.
