Ok, I cant find what i need to know by searching, so here goes. What do i have to change out to make a P72 work on a H22a both are OBD1. And i would like opinions of which is better between the P13 and the P72. Thanks

 

anyone?

 

i personally like the p13. if both is OBD1 then it should just plug in and play

 

from testing both. the P13 (JDM with a spoon chip) vs the P72 with the XS program.
P13 seems to make much more HP/trq. throughtout the powerband. also no dip in @ vtec switchover.
p72 will just plug and work. but I would persoanlly go for a chipped JDM p13

 

I usually reprogram the P72 to work the h22 motor, injector pulse stock over stock is different due t different injector sizes. Timing maps are slighltly different as well since the h22a does not like as much timing as a b18c

if you want a chip feel free to PM
