BlueZ31 Posted November 17, 2011 Share Posted November 17, 2011 Last ECU based question for the forum. In light of the issues I'm having with my JWT tune, I'm looking to go back to a stock ECU rather than risk engine damage with a overly lean tune. From what I take off Redz31.net, injector feed type doesn't matter, just impedence and 02 sensor type, and transmission for N/A vehicles. Local scrapyards don't have ANY z31's, and the only ECU's I have are two CAL turbo units, one 85, and one 88. I can, however, get my hands on a 80's Maxima unit. Would this work without degraded performance, in a Z31? What are my options as far as possible temporary swaps while JWT works my issues out? Thanks again to all who bother to read and reply.

Bates_ Posted November 17, 2011 Share Posted November 17, 2011 How big are your injectors? Quote Link to comment Share on other sites More sharing options...
BlueZ31 Posted November 17, 2011 Author Share Posted November 17, 2011 Stock 180cc injectors, stock MAF. Quote Link to comment Share on other sites More sharing options...
Bates_ Posted November 17, 2011 Share Posted November 17, 2011 And you are boosted running 180cc injectors? Quote Link to comment Share on other sites More sharing options...
BlueZ31 Posted November 17, 2011 Author Share Posted November 17, 2011 No it's N/A. Theres a better description of my vehicle in the Jim Wolf ECU issues post, I just need to know what Maxima ECU is swappable into my N/A '87 300zx Quote Link to comment Share on other sites More sharing options...
Bates_ Posted November 17, 2011 Share Posted November 17, 2011 Then a 2nd gen, 89-94 GXE and 89-91 SE should work without swapping anything else over. Quote Link to comment Share on other sites More sharing options...
BlueZ31 Posted November 17, 2011 Author Share Posted November 17, 2011 Maxima is a no-go. '90 and up that I searched today with the vg30e have a drastically different ecu than the Z31's Quote Link to comment Share on other sites More sharing options...
s30red240z Posted November 18, 2011 Share Posted November 18, 2011 the ECU pinout is different, you have to pay attention on injector impedances. Quote Link to comment Share on other sites More sharing options...
Bates_ Posted November 18, 2011 Share Posted November 18, 2011 Strange since I know people swap Z31 ECUS (turbo and non-turbo) into Maximas. How about trying a M30 ECU? Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted November 23, 2011 Share Posted November 23, 2011 M30 has a different connector. It does run the L28ET nicely in my M30 after customizing the M30 harness. Quote Link to comment Share on other sites More sharing options...
