Early R/S chassis rear wheel speed sensors bolt into the Z diff and work directly. I don't have a solution for the front though.

Is the afm supply 12v or 5v?

Most piston engines seem to like 360-420 around idle, I ramp it up with engine speed also.

R33 gts-t have a 2 speed fuel pump controller. You should be able to test the speed output with a multimeter, back probed the fuel pump wires on the tank lid. From memory its 9-10v on low speed and 12-13v on hi.

Have you logged bap and speed to see the effect?

Temp sensors need 0v/sensor ground not 5v.

I'd be looking into the injector dead times.

Grab a set of r35 coils and bolt them in with a spacer and a longer bolt. Wiring is the same connector and pinout.

Could the trigger disc be in upside down?

You have 2 issues. First is the ecu does not control the starter motor in a s14. The ecu wont run when its locked.

Those injectors have a dead time of .67-.68 ms at 14v.

Make sure you're on the latest firmware, there was a problem in a recent release. Its in the firmware notes.

R34 GTT has a different connector. The 300zx ecu won't plug in.

Blue wire/white trace is +. Comes in via the connector near the ecu, also powers idle control and narrow band 02.

Out of curiosity... which pumps and fuel reg are you running?

What's in the right hand port? That needs to breath without restriction.

Did you account for the -5 degree mark on the crank pulley? Almost every SR that I tune is 5 degrees out due to this.

Fuel pump speed control working correctly?

These would normally be connected to pin 16 on the ecu connector.

Yes. The factory boost solenoid wiring.

Boost solenoid can be wired directly to the oem wiring next to the power steering reservoir. Iat can go on the expansion. Sensor ground and temp 3.

The 2J idle valve that I checked (for the exact same reason) had a 1-way valve built into it.

Connect them in parallel.

I use the Motec DMC-D for this.

I find low 400's works well at idle and light load. Usually have to chase the VCT a bit with inj timing also.
