for my manual s12 v6, the 86 300zx ECU, does it has to be from a manual, or can be from a automatic?? is there a different in atuo and manual ECU???

From what I've heard, you can use an automatic ECU in your manual S12, but you can't use a manual ECU in an automatic S12.

..ive heard the opposite....LEWIS, where the hell are you?! <

o well, i'll wait for a answer that is for sure.......

My answer was from what I remember from Lewis (Crowbar). The automatic ECU will not interfere with a manual transmission. However a manual ECU is lacking the programming that an automatic equipped car needs.

Yes the auto 86 300zx ecu will run in a standard tranny VG30e 200sxse. But the opposite is not true. The auto tranny car has a different TB switch with both an off idle switch and full throttle switch also.
I am running a 88 Maxima ecu with 300zx MFU right now because the car is getting ready for winter. I get great gas mileage also but limited performance. Still runs great. I run a 88 300zx ecu in the non-winter months.
I have been busy this year but still can get parts. If anyone is serious about parts (and many never come through with the money) email me and I can hook you up. I got TB, 300zx MFU, fans, etc.

about the ecu, the 86 turbo and non-turbo ECU will both work for our s12 v6 right???

I am not sure about the turbo ecu working unless you had all the turbo sensors etc. But the 86 is a drop in and you should use a 300zx MFU also.

To bad you couldn't just have a switch to switch the Max and the 300 Ecu's instead of pulling one in favor of the other. Or some how load info for both into one CPU and have a switch telling the ECU which one to use, Like a performance/Econo Switch.

It could be done. It would just involve a bit of wiring.

one good pair of wire stippiers, one good soldering IRON (not gun), lots of 60/40 rosin (not acid) core solder, and about 300 ft of 14 (16?) AWG wire. and one SPST switch, and its done..lol

is it worth it??? i have a turbo 86 300zx ecu. i dont want to go through all the wirering for nothing. should i just get a 86 300zx non-turbo ecu???

The only reason for any of that wiring is if you where going to turbo your car, or have 2 ECU's and have it to where you can switch between the 2. Like a 300zx ecu and a Maxima ECU, one for the performance, one thats more economical. And yes, its probably better to get the Non-turbo (N/A) for our cars. The 86 is a straight up drop in, anything newer (Say 87-89), you would have to use a different O2 sensor and have where it screws into changed as its a different size.

Actually a 86 turbo ecu is worth some money. 50-75 bucks. Sell it and get a 86 non-turbo if you can.
I use any ecu because I turn the stock O2 signal (a varying resistance type) in to a voltage producing type. Its very easy.
Its not that hard to swap in different ecus and hardly worth the risk of using two.

what is the number on the 86 non-turbo ecu??
what do you mean by turning the stock o2 to a voltage type??
how does that work?
