I have a b18c swap in my hatch. The head is built but the bottom end is stock. It has i/h/e. I am currently running a p72 with e-manage. Now that I put in new cams and valves I would like to step up my tuning platform.

So.....I would like to know is it better to chip the p72 I already have or get a p28? I am going to be using Crome for the tuning. Thx for all help to come.

 

nevermind, from readin I have found that both will do the same for me whether it be the obd-1 chipped p72 or obd-1 chipped p28.

 

Only positive to the P72 is you get the knock board, which will allow you a partial tuning aid with new maps.

Once you got it down, disable the knock sensor!

 

and the IAB's output wich you can use for so many other things..
