89 CRX W/ZC swap CODE 8

Hey people what's up??? Well here's the deal... I just bought an 89 Crx with a Zc DOHC swap. I am running the Zc with a PM4 Ecu. The check engine light has been on since I bought the car. I finally ran the codes last week and I got error 4 and 8. Code 4 was the crank angle sensor which I fixed by timing my distributor. Now it is no longer giving the code 4 error. Now I am only getting the code 8 error. Something about top dead center. Well I took my car in today to Powerhouse Imports and had my motor alligned with my head at top dead center. After getting home I reset my ECU hoping this would've fixed the problem... but it didn't. I have no clue what to do now. I have heard that I should be using a PM6 to pass Arizona emissions. People tell me to use this ECU but is what I want to know is.... is this PM4 feeding me bogus codes?? Is this a common problem code when using the PM4.... meaning if I change to the PM6 would the error code go away?? If not then what else could be the problem?? If anyone else has had this problem and fixed it then please help!!!!!!! :banghead:

Oh yeah by the way... I forgot to mention... When I start the car in the morning, when the engine is cooled it idles at 2000 rpms and when it warms up, it idles at the line just below 1000. Sometimes it idles up and down in between that line and 1000. By the way still beating my head against a brick wall trying to figure this one out.... somebody please help me!!!!!!!!!!!!!!!! :banghead:
