Hey guys

I've been having a few issues with my r32 GTR running rich and loosing power over 6000rpm. My mechanic has done a bunch of work and it's spent two days with a guy with a dyno who is unable to identify the issue. He said it is likely that there are internal mods to the engine which we don't know about because i bought it with a recently rebuilt engine, but we don't know what's inside.

Mods are as follows:

garret 2560r turbos

3 inch dump pipes

3 inch exhaust incl high flow cat

high flow HKS panel air filter.

manual boost controller (set at 11psi)

The mechanic said that i will need an aftermarket computer to get around this issue. I am wondering what the best to get is. My understanding, from reading lots of posts of aftermarket computers, is that the apexi power FC has basically every option that could be needed. I don't intend to do any more modifying, and just want the car to run right again so i don't need lots of extra options. What i'm asking though is whether the Apexi power FC is likely to be able to fix this issue.

He has suggested the wolf 500, but this costs close to $2000, and i am wondering whether it is likely to have any more options to get around the issue which i have. I guess what i'm asking is what are the advantages, if any, of the wolf?

I've found a apexi power FC in the for sale section, which says it is for the 32 GTR. Are there several different models of the same apexi power FC, or were they made differently across the years with different features?

look i know alot of people are gonna wanna kill me for saying this but i am gonna say it based on what you have said in your post:

"I don't intend to do any more modifying, and just want the car to run right again"

get your hands on an apexi SAFC2. install and tune and it will stop the car running rich. knowing you dont intend on modding it more its a viable option, that with install and tune will only set you back about $500. (provided you buy SAFC2 second hand).

if u feel you may change our mind and want to mod your gtr more, then a Power Fc is good buy now. things is you dont wanna get an SAFC2 then decide you gonna mod more and buy PFC. its just wasting money on install and tune and time too.

sit down and really think about what your end target is, if its power get a PFC, if its really just to get the car to run at a proper air/fuel mix and get some better economy, get the SAFC2

For $900 or so, the PowerFC cant be beaten.

And yes, the mech/tuner is right. Your running much larger turbos than stock.

This required tuneable management.

So, it sounds like the Power FC will have the options required for this?

Does anyone know the model number of apexi power FC that i require? Is it PFCRB26 - which is suitable for both the r32 and r33 gtr?

      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.

      Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:

      Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
