I ended up pulling apart most of my body loom to rewire things and from memory that output shaft speed one came through one of the 3 auto plugs attached to the rhs fender just above the chassis rail in front of the strut tower. That means if you don't your speed signal being fed into that plug where the auto box loom plugged into you won't have any speed signal coming through that ECU pin.

Ok I’ll check that out. My Speedo works in the cluster so I would assume it is plugged in. Just no signal wire from the cluster to ecu

As a side note to this I manual converted an RB25de S2 stagea (Grey plug ECU because Stagea and the pinout all matched up to the NEO motors) and I did have a wire in pin 29 which was the speed signal from the dash.

My speed signal wire was yellow with a green stripe.

Thanks. My gauge cluster was swapped to the manual one  So I’ll pull it out and run a wire from cluster to ecu. I’ll also try swapping pin 58 to 29 and see if it works as well

Your map is fine.  You will have to get someone to check the wiring in the car to find where the signal is lost.  Speed signal should be present on pin 29.  The speed signal voltage needs to rise above 1.5V and fall below 1.0V.  

Hey so I did some poking around and pin 29 has no wire in it. From the ecu Pinout I got it looks like pin 58 is a signal wire. (Signal 1) or do I have to run a wire from my cluster to the ecu to pin 29? I wonder if this is part of the reason why most of us can’t get launch control to work on our cars lol the car was originally an rb25det neo automatic but was converted to manual tranny and original engine harness was still used just the tranny harness was changed in the conversion

Ok I’ll pull it apart to have a look. Thanks.

As far as I know the speed signal comers from the speedo and is a square wave so should work from low speed.  

Can you attach your map.

ya it should be working out of the box lol heres my current saved file

[r34 skyline gtt closed loop]

hello.im trying to understand the closed loop in my map and how to set it up. i have my target air fuel table setup as boost reference as the car pretty much runs at high boost (25 psi) most of the time

.  i have my map almost complete. i still have the oem o2 sensor running and also have my wideband connected to the ecu as well. if someone could have a look at my map i would very grateful
