Ok. Ive been searching and searching everywhere about this issue. Ive found many post from people having the same issue, but no solution is ever given. All EDUCATED input is welcome.

I put a b18b in my 96 Hx 5 speed. starts and idles fine. when I snap the throttle the engine boggs out and shuts off. If I step on it slow it will hit the rev limit at its normal point. So needless to say its not being driven. Im using a 96 ls ecu. I put the hx ecu in does the same and I used a friends ecu same issue.

I checked to see if the map and tps were switched. They were in the right place according to wire diagram. I even swapped them for s**ts and giggles. no change. checked cam and ignition timing.

known issues...

primary o2 sensor not plugged in. Just figured out how to do that. but in my 9 years in the automotive field ever had car bogg out because of that.

pulled codes and of course found for both o2 sensors and iat sensors. And as I write this maybe thats the issue. With both of them sensors not working theres no way to know how much o2 is in the system.

next issue. So I pulled the wire harness apart and found broken wires and a bunch ready to break. So I want to just replace the whole harness. But All I hear is the hx is diffrent. But how is it diffrent. if I use a 96 crv harness with the ls ecu what would be the problem? Because Im not running vtec or the egr or a 5 wire o2 sensor.

My main purpose for this is for help but I would like it to become a sticky for future. So much info on the hx and so little at the same time.

Thinks in advance.
