Z31 timing curves

Racer_Jim · 08-20-2007, 01:00 PM

What sort of timing curves are you guys running on your Modified ECU Z's?
I just finished my haltech install on the Z and guesstimicated a ignition map off a Z32 map I found.
22-35 pre boost, twenty under boost
So far (all of one day of tuning..) its running alright, but I just wondered what yours looked like, since mine leaves much to be desired.

Thanks!

Thanks!
I've actually made a lot of progress on it now, but I can use all the help I can get.

Oh I got a new tip for you guys that I'm sure you already know.
The non turbo and turbo late model z31 injectors look surprisingly similar... No wonder it was running up to 14.0:1 AFR's at 13 psi! LMAO The Acetone /Water Injection saves this motor again.

If I get ambitious I'll swap them out for the turbo ones, but I'd rather save up and put some 550's in, and a fuel pump... sheesh I need a raise.
