Ok first of dont try to tell me to search ive searched for hours and the sh*t is confusing because 20 different people say different sh*t. I am in the process of purchaising an ECU for a U12 bluebird (its got top mount so I think its U12 not U13). The two ecu that I am looking at are, from a W10 Avenir that is manual I believe, number on ECU is C8, 23710 95N11, A18-C58 Y53. The other ECU is from a Bluebird but it is auto, number on ECU is 11, 23710 79E10, A11-000E51 C515. My question is which ECU is better to run on my car, a B14 sentra with a U12 Bluebird motor, it is a manual. I am also not sure which MAF or O2 sensor to use. According to my searches I need a B13 SE-R MAF and a skinny O2 sensor. Ive also herd you can run different MAF as long as you are using SAFC. Here is a picture of the manual avenir ecu, and I dont have the one from auto bluebird ecu, its red lettering with a big number 11 on top!!
If you cant help dont say anything, THANK YOU!!
