i have been looking up the differences in these and so far i have found for its price it is best to go with a crome p72 ecu..but i would jsut like more information on the p72 ecu being chipped vs the p28 ecu. and also the crome chip vs the hondata chip for price.

my mods are injen intake, omni power throttle body, skunk2 intake manifold, dc sports headers, and a 60mm apexi catback.

also how do you tune it at home? if i can do that i will buy the hondata and p72 which is alot more money but i can save the money in tuning it myself.

if you have these for sale let me know. thanks

Solid

p72 - secondary butterfly support and knock sensor. Except it is the wrong knock board for the h22.

p28 - No secondary, no knock sensor support

so is p72 or p28 better for a chipped h22a4? or an obd1 p13?
