so i got a d16y8 swap in my 89 crx hf, i've had this swap for almost a year now. when i first had it done, i was running an Hf dizzy and a pg7 ecu, with obd0 integra injectors. i was getting about 27 mpg, and the air fuel was stable. recently, i had a problem with my o2, it was running rather rich for about a month. i fixed that, now i got an Si dizzy with a chipped pm6 ecu, but now its tweaking out. i have a huge power loss in lower rpm (up to about 3000 rpm), im getting about 20mpg, and my air fuel is tweaked, its going from the first rich/last stoich mark, then jumps alll the way down to the bottom lean, and bounces back and forth, also, its all the way in the lean when i first start off, then kicks over to stoich/rich at about 2000rpm. guys at axiom said it was timing, that the dizzy was completey wrong and its ******* everything up, but why was it runnign right with the hf one then?? sorry this post is so long, but i figured it would be better to get all the info out.

 

are you getting any CEL's ?

 

no, i was getting the o2 one a month ago, but i fixed that, now theres nothing

 

Hmm...What is the PG7 ecu out of? Early Teg?

 

i think it was 87, but im not sure.
