Let me tell you what I got. 1994 civic b16a with a P30 ECU and a Apex-i Safc. What I can't figure out is...every time I try to lean out at idle (I have bigger injectors) I instantly get a check engine light. I have double checked my wiring on the apex-i and everything is cool. The injectors I am using are mustang 30lb/hr....about 317cc (blue tops) I would think that the reason I have a problem is the injectors, but they came out of another civic that did exactly the same thing that I'm trying to do. The other civic was a 1994 1.5. I can't figure it out? anybody know?

 

Uhm, how about telling us what Check engine code you are getting?

Are these injectors hold & peak or saturated?

 

Sorry, forgot to tell you that DUH! It's a O2 sensor code. I'm not sure what type of injectors they are, but I do know that another guy was using them the same way I want to use them with no problems. It was in a 94 civic with a 1.5 motor...it was OBD 1 also. Sorry that I put this in the wrong spot, I keep forgeting that you have a place set up for just eng. management stuff....You know what, while I've got your ears.....what do you think of greddys' E-manage? I've been thinking about switching to this anyway...Then I won't have to deal with the Apex-i anymore.

 

Just an off the top guess but maybe O2 sensor is reading a rich/lean condition therefore throwing a flag. Dont hold me to it tho im still learnin been lurking here a loooong time.

Later,
