What's up man, just checking out your thread and sad to see your still having trouble. Are you still on the cpr? Mine is still messing up too every time I get about 3-4 good runs at the track in before it ***** on me.

Recently I have changed the dizzy and installed a new rywire harness, Hopfully this works if not I may be going to aem set up. Have you considered switching to aem to try and fix your problem?

 

The car runs damn near perfect in open loop. Every now and then I will get a very slight stumble. Is a pretty rare occurrence and barely noticeable.

Still goes very rich when I switch to closed loop. I am working with PLX tech support to see if it could be something wrong with my the controller. I've just been driving it in open loop for the last few months. I would still like to be able to drive it in closed loop tho.

Hope you get your stuff figured out.

 

Yes mines good,

New rywire harness and new oem honda dizzy and no more trouble.

Plus my old turbo **** on me so i got a ball bearing reaper

 

Sweet! How do you like it? Can't go wrong with a Shodan turbo!

I have a set of GSC cams waiting to instal. Just been too busy to do it. I would really like to figure out my rich closed loop issue before putting them in.

 

New turbo is great like always more issues with dataloging. Lol you just can't win these days. Makes a z06 look better everyday.

 

Where's the fun in that? lol

 

Man this is really pissing me off. I spend $200 to get a new wideband thinking the old one was the problem and of course it wasn't. So now I pissed away $200 and several hours of my time swapping functioning widebands.

I can't see how the problem could be anything other than the S300 at this point. That or my calibration file and I've looked over it dozens of times. I don't see anything that jumps out as the problem.

Maybe I should just go AEM

 

Hate to bring such an old thread back to life but it contains too much information to not consider it in my situation.

I'm running a 94 D15Z1 in my 91 Crx and have this same stumble. Ive been running this set up since 2013 so it shouldn't be any obvious swap related issue. Did you ever get a solution to this? Thanks
P.S. I'm not running any engine management system.

 

then you-re not coming to the same solution. please ask this in the CRX thread. thanks.
