got my car up and running with drivibility issues

[UNISA JECS]

it doesnt have a sticker on it it just says 180sx

How about when you connect to nistune what part number does it display? 23710-XXXXX? I belive all 180SX used the skinny o2 sensor but not sure better if you give me a ECU part number, also the skinny o2 sensors AKA Titania based o2 sensor will not work with o2 sensor gauges, how are you monitoring the o2 sensor in the first place?

here is the odd thing about this if i use a volt meter then the car is ideling i get .55 volts at pin 29 and 12.98 at pin 115
but inside of nistune it shows 0.00volts but also sometimes my nistune crashes too so it might be just a bad copy i downloaded from the nistune website
im not sure how to pull up the part number

If you have a skinny o2 sensor ecu it is wired differently also, you may have a pin that is or isnt recieving the proper signal cause they are not compatable you will have to make the proper changes in the woring harness.
