Hello all. I am looking for an R34 GT-T Air Conditioning line. The one that comes from the firewall to the top of the compressor. I would prefer an functioning line, but if you have one that has been burnt through, I may take that also. Please note, I will need this shipped to America, but i will obviously pay for everything. Thanks.

I hate to dig up an old thread, but can anyone help with this situation? I am running into the same problems.

Rb25det Neo - Code 21 & Cylinder 1 Dead
syncade replied to syncade's topic in Forced Induction Performance
Well i have continuity between the ecu and the coil on all 6 coilpacks, so I'm definitely thinking it is the ECU at this point correct? And BTW, it's cylinder 6 that wont fire, not cylinder one. I was backwards on my counting order. -

I dont think it is the coils, as when I rotate them, the same cylinder wont fire. Im guessing at this point it must be wiring. -

Yes i have the pinouts, thanks though. Im very surprised nobody has ever had this problem before? -
Rb25det Neo - Code 21 & Cylinder 1 Dead
syncade replied to syncade's topic in Forced Induction Performance
I know because ive disconnected the coils during idle and the motor doesnt change at all. I rotated the coils and plugs, so I know its either wiring or the ECU. How would I check the resistance on the wiring to coil one? Just complete the loop by running a wire directly from the coil to the pin on the ecu? Thanks for the help my friend, I do appreciate it. -

Someone has to know. -
I recently acquired a consult -> USB cable and discovered Code 21: Ignition Signal Circuit. Im from the USA and i put this rb25det neo into an s14. Im running the car on a Stagea R34 Automatic ECU. I did a search on the forum and did read some other threads with a similar problem, but none helped. The motor has been running for a few weeks, but I cant get cylinder 1 to fire. I rotated the coils and plugs around so thats not the problem. Power voltage to coil 1 is your normal 12-13.5V, but the trigger voltage was only .3V (all other coils were ~.8V). I know my problem is either in the ECU or Wiring Harness, but i also read a thread on here where someone had a bad ground? Should i test the continuity to coil 1? What do you guys suggest. Ive pretty much tried everything I can think of. I dont have access to try someone elses ECU or Wiring harness, as there are only a handful of these motors in my entire country. How often do these ECUs go out? I tried to test the voltage coming out of the Ignition Signals to each coil (directly on the ecu), but I couldnt get a reading for the life of me. Besides this one problem, the motor starts, idles, and drives as good as it gets (with 5 cylinders that is). Please help me out here gents!

Hey OP did you ever fix this problem? My motor is doing the exact same thing.
