Just looking for opinons on which ECU P28 pr P72 with Hondata 300. Is it really needed to keep the Secondary butterfly valves and Spark control on a turbo H22? Trying to make the right decision with as much input as possible.

Read it, I was looking for other peoples real world opinions. And what is it with people always saying "search for it" Then what would be the point of posting on the forums. Lots of the old post are very outdated. fresh ideas are great, newer exper. is needed.

 

looking at your name, im guessing you have an SH?
you know your going to lose the ATTS right?

your car is the same nothing has changed unless you have a 2006 honda prelude those ideas are pretty much still in use

 

Yes I know I'll lose my atts.

 

You'll have a better torque curve with functional IAB, so unless you're switching manifolds it is worth it.

PS: Get Neptune RTP, cheaper than S300 Hondata, and it runs a H22 like a dream.
