Hi, I need help with ignition timing on a 1997 57GSIPLKD in a Chaparral SS2335. (The block has been changed by a workshop because of water in the engine.
From what I have learned I think the engine is a TBI-type with EFI. I've read the manual on of how disable electronic spark advance / enter "base mode" by jumping the black and black/white wires on the Data Link Connector.
The harmonic balancer has a mark and the engine block has a small notch. No other "ruler" or notches.
I'm struggling to find out if those two marks should be aligned when using a simple ignition timing lamp, or should I use one with "advance" that I can set to 8 degrees BTDC?
The mark on the block isn't on top ("at 12 o'clock") but rather at 1 o'clock when looking backwards.
Yes, I have read these two threads, but I have also learned from others that I don't need "advance timing lamp":
