Hey guys

Have had an Emanage blue sittin round for ages. Got one of the accessory harnesses for it so i didnt have to get my wiring loom chopped up / modified during fitting. Got it thru Nengun, it was listed as:

Harness - N-4 - Nissan - R32/33/34 GTR - HCR32/HNR32 - ECR33 - C33/34 - A31

Took it to my tuner today (Shaun @ Boostworx). He plugged it all up for me. Powered up fine, showed all the right lights etc once piggybacked in. Only problem he had was getting signal to the ignition. He was getting injector pulse, but no ignition pulse. In the japanese / english instructions, the N-4 Harness is listed as an RB26 wiring loom compatible. There is apparently an N-5 harness for RB20/25 wiring loom. I havent been able to confirm this as such thru Nengun, but it confused me with their listing as above.

To save dicking around with having to wait for another harness to come from japan etc, I was wondering if there was any advice to what wires to swap around on the piggyback harness at the factory ECU end to make it work for RB20DET. Shaun had said something about the AFM signal wire from the car loom side being teed to the AFM 2 port on the emanage.

I know that there is a way of re-configuring an RB26DETT PFC to suit RB20DET applications, is this similar idea possible with emanage harnesses?

Any help is much appreciated

hey mate

i dont think they make a loom for the rb20 they all seem to be for the GTR

i did exacly the same thing ordered for the rb20 but got the n-4 loom, so what i ended up doing was changing the wires over, from memory it is just the ignition and injectors that you need to change and it is just the order that needs to change, what i did was grab the rb26 pinout from greedy and compared that with the rb20, and also used the ignition and injector diagrams from the manual. i cant remember the exact wires it was but i know it was only 8 that needed changing and was easy enough to change. dont touch the AFM the right one is already, power earth and throttle are also right. once you have done that there are a few paramaters that need to be set on the emanage and it should be right to start up. if you get stuck let me know as i have just setup my emanage on my r32 and have everything running.

did you check the jumpers and rotary switch settings

shaun (my tuner) checked all them to make sure. had never been set up, so he changed them to the appropriate settings and it still wasnt working

have you got a link to where they are on the trust / greddy site by chance? so basically everything but the injector and igntion pinouts that vary. if its as easy as that it shouldnt be hard to change then

yup it is only the ignition and injector pinouts that are different, it is a pece of cake to do and you should be able to do it at home takes about 10mins to change around

this is the diagram for the ecu pinouts

      Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s

      It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.

      RB25DE NEO with Haltech ECU

      Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.

      Cas issue

      It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
