We swapped the wiring and tried that seetings still no signal no spark

sensor are reading on scope settings are correct but car not starting trigger also not reading rpm
-
i originally had the link iat sensor but it broke when removing it and now i got the new gm senor installed but im still getting an t2 at 5v any updates trying to calibrate my gm iat sensor on my link g4+
-
okay got it working had it wired in correctly pc link is not showing me the ethanol content tho it just says sesnor status ok

Have you had the engine running with sensor fitted?
yes

hi trying to set up my aem ethanol senor on my 300zx link g4+ converted to gtrlink i have the sensor wired getting 12v ign ground and digital output 4 but when i try to connect nothing happens and says error
-
firing order changed in map
-
car is a r33 skyline using the 300zx link g4+ and with the ac on if i rev the engine the car will stumble and stall or come very close to it temperatures also get very hot with it on i took a data log of the incident
-
also happens with my ecu im running the factory check engine light settings as well and the check engine light comes on after 7000 rpm. i am only running 17psi of boost and ect is 88 degrees
-
got it working just had to set it to an v2 instead of an v4 because off the 300zxecu pin 27 is anv2 0n 300zx ecu

The picture above said to place anv5 as power steering switch witch is where I have it. I originally had anv4 wired as my wideband signal but I would get an o2 sensor code and there was no function selection in the ecu for lamba 1 just o2 sensor narrowband
If you could post an updated pclr file with the sensor outputs labeled then I can just open it and wire it accordingly

Sorry, I knew I would forget after the weekend...
Ok, so below is a list of what I can see are the main differences. Most of it we can take care of with just settings changes to the ECU. The 3 pins highlighted in orange are the one you need to take care of.
The injector/ignition drive differences I took care of by fudging the firing order in the software. Attached is a map with most of these differences re-assigned and firing order modified. The only thing I didnt bother to set up is fuel pump speed control since I dont know what model car you have and if you still have the FP controller. The fuel pump will just run at full speed all the time with this map.
The picture aside to place an 5 as power steering switch and I had it originally going to anv4 but I would get an o2 sensor code and there was no function selection for lambs 1

Looked ok?
-
-
I also can't get my aem wideband to come up on the screen I have the signal wire to an5 and set it to voltage adjusted calabration table 4 and nothing
-
I had it before I change ecus but I'll have a look
-
Only got one code now anv6 I did set it to 0 started it up and drove it runs on 7ms for master fuel trim dies on anything higher or lower also have no power steering now
-
And an v6 at gnd
-
1 code an v6 at gnd but that's just my stock o2 sensor
And an t3 at 5v
-
Yes I connected iat to anv4
Witch pin should I connect my aem uego wideband too as well I currently have it to the stock signal location for the rb25 o2 sensor
-
Okay perfect I'm getting 3 fault codes ant3 at 5v but I'm not using the expansion harness and anv4 at ground anv4 is the link iat sensor i think I may have the polarity reversed
I have the iat wired into the mag signal but I realized I am going to have to put it over to pin 36
-
so with this map i will not have to change any of the settings just calibrate setup injectors and wired in auxillarys and go

Thanks allot it's a 1998 skyline r33 gtst with rb25
has a adjustable fuel pressure regulator
rb 25 running 300zx g4+ prp trigger not registering
in G4+
