Hi guys and gals,

I dropped a DOHC ZC into my '91 EF a while back and the time has come to get it emissions tested. My first attempt suggested I failed horrendously on all levels. I think this is because I am running a PM6 ecu when I need a PM7, what do you think? I hope Im not burning a ****-ton of oil or have anything seriously wrong with it.

I am just looking for confirmation that a PM7 will at the least medicate the issue til passing or close to passing? Thanks for the input!

Here's my bebe!
