Zdyne one wire B16a program on mini-me (review)
Just wanted to tell all about how this worked for me because I debated for a while and I am glad I decided to go this route!!!
Works great no problems Vtec set at 4800 I have an A6/Y8 mini me fully rebuilt with full ported/polished head intake port matched and 4 into 1 header!!
It is defianately woth while and a good investment!!!

You don't know what you're missing bro...
I initially went with Zdyne for my Z6/Y8 setup, it worked, but I later on found out I could squeeze much more power out of my motor with different fuel management.
First of all, your VTEC x-over is too early. The stock D16Y8 P2P ECU enguages @ 5500 RPMS - keep in mind the cam on the Y8 is radically different than it's Z6 brother, especially the VTEC lobe (huge overlap). Second, the B16 program makes horrible power on the Y8. Don't get me wrong, it works, but it doesn't the fill the potential of your Y8.
I've tried almost every setup known in the book to activate VTEC. I ended up getting the best results with this: '91 PM6 ECU coupled with a V-AFC, and fine tuned with an adjustable FPR. I also chipped the PM6 to get a raised revlimiter. The '90-'91 PM6 maps are very aggressive, great for the lo cam lobe, then my V-AFC makes up for the extra lift/duration of the hi cam lobe. I also have the ability to change the x-over to any rpm increment I want, AND it gives me the ability to tune the motor with future mods (ie increased CR, P&P job, etc).
Don't get me wrong, Zdyne is a great company, but they don't have the proper fuel/timing maps to harness the full potential of a Y8 head. Now if they were able to extract the actual P2P maps, then it would be a different story.
