I recently thought about switching back to obd1 with my h22/civic and wondered if anyone had any preferences. I figured that the p28 would probably be the best since it wouldnt look for EGR....etc... I see ecu's that are already chipped, and since I never cared about going obd1 I dont really know what would be best. Of course I am gonna have to chip the p28/p72 for h22 specs but I just wanted input, or maybe preferences.

My first bolt-on is gonna be the Skunk2 IM. Say Bye Bye to secondaries!

Well, i have used P72 and P13 for my H22. out of those two i like the p13 a lot better. But if your doing FI then i would go with the P72 and get hondata because you cant get hondata for the P13. I dont know about the p28 myself, so i will let someone else help you there. By the what what year is your H22? If you need a p13 i have a chipped and socketed one for sale right now for $300 shiped

 

I have used both the P72 and the P13 and would have to agree the P13 is better (other than the speed cut at 112 that my jdm ecu has). Import review did a comprasion of these two and it shows that the P72 has much nicer top end over the P13 but the lag that you experince due to the earlier change over is pretty harsh. At least it was on my setup, could be differnt for others.

 

p28 with hondata (coming soon!!)
