As long as you are getting it tuned professionally you can't go wrong in terms of blowing it up. I posted a link to my thread because I have the Powerplay ROM tune. 666DAN has the bikirom working but not tuned yet. He will be getting it tuned in the next month or so I'm guessing. I think the ROM tunes are about to come of age. If I am right your upgrade outlook may change.

That said, putting a slightly larger turbo and a bigger fuel pump with adjustable fuel regulator will give you a nice improvement as will a SITC if you can find one.

Gary, you certainly do have a way with words.

SO to clarify, once the SAFC-2 is tuned it holds it's memory even if ECU is reset?

And the car will not suffer any adverse affects from the SAFC-2 being installed??

Sorry to ask what seem like stupid questions. I just want to be certain.

Cheers

1. Bullshit

2. No

:O cheers :blink:

Quick question; is there any substitute to the S-ITC?  Having real big problems finding one :P

With the mods that you intend to do, I think it would be a good time to invest in a piggyback such as those listed if you are gonna keep the auto. The emanage can be ordered with the vehicle specific harness kit making it a plug and play affair.

I don’t really want to get into EManage bashing, but I haven’t found anyone who has got one to work over a long period of time.  They have always had some issues with RB ignition systems, the zener diode mod seems to at least allow then to run, whether it stands the test of time is yet to be proven.  The instability in high temps has been cropping up lately, maybe it’s a phantom or a symptom of the recent hot weather, I don’t really know yet.

All that aside, I still think (for what it does) it is grossly overpriced by the time you ad all the bits necessary to use its full functionality.

:( cheers :angry:

As I've said numerous times, my one was running fine for 18 months (60,000kms) with the diodes in place, I'd say that's a enough time to see that it works.

The main problem with 34 coil packs is that they are basically poorly built, they seem to have severe problems with the heat and die quickly. I've had this happen in both of my R34's pre any ECU modifications.

The series II R33 coils seem to be a great replacement, but they don't fit as the mounts are in different places requiring a bracket to make them fit...but the definately seem to be more heat stable.

I'd say you'll have no trouble finding anyone to tune the bikirom down south, it's just a ROM plus the new edition of software Lucas has provided comes with a self-help menu for specifically tuning the R34's...a chimp could do it if it owned a dyno.

1. Yes, even if you unplug the SAFC and put it in your cupboard for a year. It's like an elephant, they never forget.

2. If it is tuned properly, no adverse effects.

3. Sorry for the previous abrupt reply, but workshops trying to put people off stuff that works and has worked for years and sold thousands of units worldwide really peeees me off.

:D cheers :(

SK, Not upset about your reply at all. Actually, I expected a short and to the point response.

This garage who I will not name have proven to be very opinionated in the past, and I am not the only one who has had this happen to them.

So I just wanted to make sure that I was not going to do any harm to my car.

Cheers

OK, all the parts have been purchased except for the Cat... I'm thinking about the 4" Magic Cat as was in the Group Buy thread.

Question: Does anyone know of a place that can bore out my oil lines for the turbo? Somewhere in Sydney? I've been told it's only the O-Ring that needs to be bored out and welded up (from 1.9mm to 2.2mm)

Too true, but now I am looking at the Bikirom option. OMG, :) so many options all of a sudden!!!!!

Better get that SAFC in Pete!!!  Otherwise all those emails and MSN convos will have gone to waste :)

OK, the work has begun... YAY! Race against the clock to get it all together for the Sunday BBQ but if we don't make it, it's not that big a deal.

Few Questions:

1) The Fuel Pressure Regulator is running at 30psi @ idle and 50psi @ max boost (10psi on stock turbo). We can adjust the FPR but at the moment the car is running fine. Does anyone know what the pressure should be set to? Or is it dependent on the new turbo/power?

2) There is a "Fuel Damper" just before the FPR... kinda looks like another FPR. I want to know if this can/should be removed as it will be a "restriction" to the fuel flow.

3) Bosch 040 in-tank, is there an installation guide for this on the R34? Having some trouble deciding how to mount it onto the stock bracket whilst maintaining the full function of the new pump.

Think that is it for now :ban:

Thanks for any replies that may follow; your help is most appreciated as always!

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Automatic Power Button Light Flashing

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
