A chipped p72 is really the only way to go if you want to keep iab/knock, just make sure you know a good tuner.

It is possible to add iab to a p28(xenocron add-iab chip kit = $5), but I'm not exactly sure how that works...you'd have to ask someone at xenocron or someone on the pgmfi forums. There is currently no way that I know of to add knock to a p28.

I really don't see a point in keeping knock, personally. I am also deleting my iab & egr before my car goes in for a tune, and knock will obviously not work any longer since I'm running a p28 equivalent ecu.

 

pricewise, P28 is cheaper and hondata s300 if you have the money.


Prelude ECu are not really tunable. p72 is a little more but if you're turboing it. P28 is Darn Good.

 

how do you get rid off the aib? and if you do are'nt you gonna run into any problems with loss of hp or idle? i have heard people saying that,don't know if is true or not.
