Just bought the FAST EZ-EFI kit from Z Car Depot for my 1983 280zx. Put it on my car the other day and it runs worse than it ever has. Car will idle but is very hard to start and really rough when it's running. Using any more than 1/4 throttle will stall the engine. When I am able to rev the engine it's terribly rough. Feels like or an ignition timing issue. I know that when I removed the old EFI harness I disconnected a connector going into the distributor and the new harness did not have a connection to plug back in to the dizzy. Since adding the EZ EFI, ignition timing has retarded itself about 10 degrees at idle. Advancing timing does not help the issue. I have setup the ECU with all the correct parameters listed with the info from zcardepot. ECU doesn't throw any codes, all readings seem mostly normal for not being tuned. It feels like it could be a vacuum leak or vacuum not hooked up correctly as well however my vacuum readings are perfectly normal. Has anyone else has this issue? I will add pictures of the engine in it's current state along with the connections that were left unplugged when adding the EZ EFi kit, Including the oil temp sensor. Does this stuff really get left unplugged?
Hey guys, Im currently hunting down rust in my project 77 Z, and i removed the Wiper linkage assembly and the motor that sit under the cowl area. Its in pretty rough shape as is the steal in the cowl itself, but that's for another time. What i need is a diagram and part numbers so i can get in touch with a dealer somewhere, that has some of the misc pieces i need. I've tried many times to get a working copy of FAST, and well with my recent plunge into Win 10, i don't see that happening anytime soon. Anyway, hope someone out there has a screen shot they can snap for me. Much appreciated. -Kyle
