Hi all,

I've got a faulty "ECR33" Power FC, just been diagnosed with a water damage. :P

Every function works except for the one that controls the injectors. :)

I've been told if I can get the chip (5D4T313-151007) replaced, should work as usual.

I'm aimming to find out if there's any interchangeable chip available before sending it back to Japan via Nengun ($14,000 JPY to reset the PFC, + shipping cost to Japan and back + additional repair fees) :D , so if people who have Power FCs can please help me find out whether you have this chip in your Power FCs will be wonderful.

Hopefully most Power FCs share the same design and chips.

Thank you all for your time. :D

most of the r33 get a faulty main processor which is the large one in the socket. The reason r33 powerfc's were discontinued was because that eprom was discontinued and is impossible to replace... so if that main processor is kaput then the powrfc is not repairable.

I repair about 4 or 5 owerfc's a week and unfortunately most of the r33 ones have a dodgy main processor and it cant be replaced as it is no longer in production.

It seems to be only a r33 issue most other pfc's just have dodgy capacitors or igintion transistors.

Only a handfull of PFC's run that large processor (all now discontinued by apex) it is not common across the whole range. Those whithout this processor are still available new.

take a look at the IC chip it is the same. but IC 15 is the igntion driver and you should have no spark when this is bad. a good test is to pull all the coils off and put plugs in them them remove cas sensor, then with the ignition turned on turn. then turn the cas sensor clock wise slowly this will simulate starting the motor, you should hear the fuel pump prime and injectors fire, but no spark. i can fix it for you if you like, and test it. Please send PM if you still alive. lol

only the first batch for the first 2 yesrs were like you say then they fixed it,but didn't want to be liable so they pulled out. that is the truth, i can provide manufacturing dates of bad batch if you really need it.

      What brakes on R34 GTT(Europe)

      By Duncan · Posted

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
