Re: Y8 Timing
LC1 are glitchy; if they were more stable I'd own a million of them. Check it for codes in logworks?
Enjoy the attachment. Around the 13.5 psi mark it gets too rich; car was running out of fuel pump. Ignition is dyno tuna'd to 10 psi, and various ppl report they lock the timing past that bit. I yanked another degree or so to be on the safe side; 7-8 degrees @ 10+ psi should get the job done, with base ignition timing set to 12 degrees by yamming the distributor all the way.

Re: Y8 Timing
I'm using 1.2.0.24 with ABT+ 2.0 and FVFT 1.99RC4. Crome Development forum under FVFT 1.99RC4 thread links to current developmental version of Crome. Read whole thread; you have to uninstall older ABT and FVFT versions. This is latest in cutting edge hotness, you will jizz your pants.
Pay close attention to individual cylinder trims under Advanced Tables. ----------ing #3 is sucking 10% more fuel, because flow is not particularly balanced through a Y8 IM, the log manifold on the car, nor the stock fuel rail at those pressures/powerlevel.
Set that skrill to 1.000 all the way across, take a few pulls, and richen up the cyls that show signs of pingies on the *fresh* plugs. Dunno what your engine will like, but BRK7E-11 or R5672-A8 is around the heat range you'll need for 10-15 psi.

I'm gonna try to find that new version and hopefully they'll make more sense.
