Er34 Vs Stagea S1 Pinouts

[Klymax]

Hi guys,

Installed a powerfc and have some problems like some S1 stag's are having, though the pfc should be plug an play (to a degree) with my R34 GTT.

Done some checks and found the following

- Voltage for the throttle motor sensor (pin51) is approx 4.62v.

- Voltage on pin 23 when car is on ignition 0.01 to 0.02 fluctuating,

- Voltage on pin 23 when car is idling is 0.00

- Voltage on pin 37 is 0.00 at ignition and idle

- Voltage on pin 53 is 0.00 at ignition and idle

- Voltage on pin 79 is 0.00 at ignition and idle

I've been told they should be as the following

Pin 23 should be 0.5v approx idling

Pin 37 should be 0.5v approx

Pin 53 should be 4.7v

Pin 79 should be 2v approx

Pin 51 should be 3.4v

symptoms are the following - A/C compressor wont turn on, TCS, SLIP and MIL lights on. powerFC sw sensor check has the THR black background

Im quite lost as to where to look and why so many pins are having no output.

Any idea's where to check?

Series 1 stagea's there are 3 different wiring pinouts/ecu's. I have a series 2 stagea with the neo rb25 and did use a power fc for a while with no problems except for the engine check light which comes on due to no traction control on awd stagea's.

I am a bit unclear to what car/engine combo you have? Is it a stock R34 with the original neo engine, or have you fitted a series 1 stagea engine to it?

Hey mat,

sorry I should have specified. The car is a R34GTT (ER34) manual with the original neo rb25det. Unfortunately I never had a stock ECU, just an Impul replacement. The impul unit when installed runs fine and no error lights on the dash. a/c TCS can be turned on and off as normal. then switch the loom back to the PFC with the problems as above

Cheers

Anyone have any ideas? Could so many pins be un powered due to a relay or similar failing?

[Klymax]

Anyone at all encountered this on a R34GTT or have ideas?

i have workshop man for gtt pm me

Have a copy of it mate, but thank you for the offer. I just fail to see a connection between all the modules and why so many are failing at once.

Cheers
