I am looking for some base zdyne settings for a turboed ZC. The motor is rebuilt with eagle rods and rollerwaves. The head was rebuilt and ported. Using a walbro 255 fuel pump and 450cc injectors. The turbo is the IHI/apexi hybrid from the Apexi D16Z6 turbo kit. Using a greddy profec B boost controller. CR should be around 8.9:1. Any help as we get into this phase would be greatly appreciated.

 

Grab the PR4 .zdy tune that is floating around on the internet. I can arrainge to have it mailed to you if you don't run across it, I have friends with Zdynes.

ZC and OBD0 LS have almost the same ignition maps, but the fuel will be a bit richer. I'm running PR4 ignition on a friend's Greddy SOHC turbo ZC, it's a pretty happy car.
