Will you please drive to me, I think my turbo ecu or my AFM is faulty and I want to test out a couple, it'd be a HUGE favor and what's in for you is: a beer, and i will pay for your gas. Message me for more details.

 

Wish I could help you out, all I have left from my stock efi days is the AFM (which I can't remember if I left it tweaked for 370cc injectors or not) and the stock turbo injectors. I sold the ecu regretfully. I do have a stock turbo Z31 ecu in case you decide you want to try the swap to Z31 stuff.

 

lol, thats what I've been trying to push him on.

 

what are the pros/cons of the Z31 setup anyways, I'm told to do it but no explanation on why its good WHICH I DONT DOUBT but just because i'm curious, why is it better?

 

because the ECU from the s130 compares to a modern graphing calculator, where as the z31 is built off a more modern base. the biggest selling points are better reliability and it uses a MAF instead of the flapper box.

 

Basically what Hoov said plus the stock fuel map goes from extremely rich to beginning to run lean up top. My a/f went from ~10.1 around 4000 rpm to ~12.2 by 6000rpm. This was on a stock setup, so I'm sure a car with more boost/mods would be running a lot worse (if stock injectors are still being used). The stock map on the Z31 ecu maintains at least 10.5-11.0 all the way to 6000rpm. There is definitely room for improvement, but it's loads better than the original map from the S130's ecu.

The next time I have to go up towards LA, I'll pm you and you can check out my Z if you want to see if the Z31 setup is for you. It's best to test things before making the plunge, and I don't mind meeting up with fellow Z enthusiasts.

 

hahhah ahahahha ahha i just noticed my thing under my name, whichever mod did that... and yeah lifegrd shoot me a message anytime you come up to LA! I'm in now in the Torrance/redondo area!!

 

lol, i asked questions like you did, but when it came down to it, i probably only spent a total of 10 hours performing my motor swap and wiring (like removing old motor and trans and installing new one included) this is the worlds longest EVAH!
