Re: Need help by this friday or the world will be doomed
You don't have a Z6, you have an OBD1 converted Y8.
Ignore the block stamp, pay attention to the head as it dictates EVERYTHING.
Your ignition timing is 9.75 degrees off due to the Y8 cam being indexed differently than any other D16. This is why the P2P mappings have 9.75 degrees added to their minimum timing maps; the cams came out fucked up for some reason, and Honduh engineers decided to do a data table hack since centered distributors look better. There is ABSOLUTELY NO WAY an OBD1 converted Y8 will have a centered distributor, it's going to be yammed as far as it can go in one direction. Whip out a timing light and figure out which way that is.
------------- has both my stock MAP and 2.5 bar tunes of Steve Simmon's T04E Y8 coupe. Run them, the ignition timing will save you headaches. You can not treat a Y8 like a Z6, or you will have issues. You will have cold startup stalling issues with the .bins on xenocron's site, but I have the correct warmup curve for them jotted somewhere, hit me up for them when you are ready, you can edit it yourself under Advanced Tables in Crome.
