i drove my car for the first time today..a b20z in my 89 si hatch. i used the b16 tranny and distributor, and a 90-91 LS intake manifold. the ecu i'm currently running is a pm6 from a crx si..i expect to have my 90-91 LS ecu tomorrow. ok, i drove it home and didn't have any problems..i drove to a friend's house who lives 15 minutes away..about 5 minutes into the drive and the check engine light came on. performance was immediately gone..the car stumbled like crazy, but was still able to make it to my friend's house. checked the codes and got a code 1 O2 sensor and a code 20 electric load detector. i pulled the hazard fuse at my friend's house and the lights went away. sure enough on the way home, CEL popped on and the same codes were flashing. anyone have any ideas here? i'm using my b16 exhaust manifold so i'm going to switch to the other O2, but i have no idea why the code 20 came on. maybe having the pr4 ecu will fix this? thanks for any help...

the correct ecu should be here this afternoon. i'm thinking the code 1 is from a lack of fuel? dunno about the code 20. any help? hoping the pr4 will solve the problems..

haha..no help eh? i'm thinking the b16 distributor is not getting along with the pm6.

i know the feeling bro i now have teh vtec situation straightened now skunk2 im woes and its missing like nothing else i have seen before. no cel though
so i am stuck once again im gonna change the plugs and i think i hear the slightest detonation from the advanced timing of the skunk ecu and teh dist
so m in the same boat
good luck man
could be fuel though

let us know when it gets in.

SuperCivic

it's in.

i went out driving with my boy..it's a different car.

no check engine lights tonight! i'm pretty sure the o2 code showed up for lack of fuel, and the 20 came up because i was using a b series dizzy on a d series ecu..maybe different voltages?? i'm keeping my fingers crossed, i'll be driving it more tomorrow. i have an erratic idle, but hopefully i can clear that up by cleaning out some sensors. anyways, the b20z rules me. just ask the rubber tracks laid down in my driveway.
