z or bust Posted August 8, 2007 Share Posted August 8, 2007 Ok so it does run...but not really. Ok I have an 83 280ZX turbo w/ N/A electronics. I was having problems before with my car sputtering while I was driving but ok at idle. Well I came back two days later and started it up and it was missing very badly. Well since then i've cleaned just about every connection, got new injector wiring plugs, and bigger injectors (not sure what size they are but they came from an 84 50th 300zxt.) Anyways I'm stumped on what my problem could be. Has anyone had this happen before?? Please let me know. P.S. If you're using N/A electronics and bigger injectors do you have to adjust the AFM?

Vintage Posted August 8, 2007 Share Posted August 8, 2007 turbo w/ N/A electronics What all do you mean by NA electronics? NA ECU? NA AFM? Either way, probably not the best idea. Quote Link to comment Share on other sites More sharing options...
z or bust Posted August 8, 2007 Author Share Posted August 8, 2007 The car was an N/A. So I rebuilt the engine as a turbo engine but I still have the N/A everything else. Yes I know that its not the best way to go and I plan on doing megasquirt soon but for now I just need it running Quote Link to comment Share on other sites More sharing options...
ab0z Posted August 14, 2007 Share Posted August 14, 2007 Just to clarify - the car was an NA car. The motor now is rebuilt, and has a turbo attached to it. The ECU controlling everything is the original unmodified NA ECU. Is all this correct? If so, you need to switch to the turbo ECU or get the MS hooked up and configured before you can expect it to work. Quote Link to comment Share on other sites More sharing options...
z or bust Posted August 14, 2007 Author Share Posted August 14, 2007 Uh no it will work. My afm was bad. Car runs fine now. Plenty of people has done this before with N/A electronics. Quote Link to comment Share on other sites More sharing options...
ab0z Posted August 14, 2007 Share Posted August 14, 2007 Well I stand corrected - this is good to know. I've seen a few NA cars converted to turbo that straight up would not work with the NA engine management. Thanks for updating it with the AFM fix - glad to hear it's working now!

z or bust Posted August 15, 2007 Author Share Posted August 15, 2007 Yeah I'm going to use an et harness and switch to a z31 ecu pretty soon. Quote Link to comment Share on other sites More sharing options...
