Hey guys i just purchased a power fc with hand controller.

The pfc has a tune that was done by hitman on a r33 with the same mods as mine.

I tested it and the max knock i could get floggin it at 10pm tonight was 25. It only got 25 onlce, mostly would be arounfd 14-18 knock.

Going by this ruff diagnosis will this tune be fine for me to use for 5 weeks till i can afford a decent tune if i monitor knock?

I plan to wait till i buy a turbo then get the whole lot tuned.

Thanks in advance guys

If you just drive it sedately, there is no reason why it wont be ok.

If its not knocking then thats not too bad

I wouldnt go flogging it though. I would have it all checked with some AFR's aswell as Risking said.

Might only require a touch up, or maybe nothing at all and it'll cost you basically a couple power runs ($80)

Thanks for the info guys,

I was of the assumtion that if it had low knock and the car sounded and felt right it should be ok? If the Air/fuel was lean wouldnt that cause a knock reading?

What if i erased the tune and ran the base maps? would htat be any safer?

I might enquire about gettgin it checked tomorrow, jsut dont wanna spend money as trying to save for a turbo then get it tuned.

Cheers

Just drive it sedately... then it will be safe, just like the base map :laugh:

If you dont wanna spend the coin for a few weeks or whatever.

I would suspect it would only be a mild touch-up to the map anyhow.

There are other factors, but that doesnt matter for what we are talking about.

If you just put some self restraint on your right foot...

Thats all the safety you need, either that or put the stock ECU back into it and go back to how it was :sorcerer:

Id recommend you be putting the stock ECU back in. Unless you can keep off the right foot.

Lean AFR's have nothing to do with the knock readings unless you are pysically out of flow and its really leaning out big time.

My GTR was maxing out the injectors at 1 bar. Run 1.1 bar and it would detonate. Put in a set of 800's and countered for them with the Same ignition map and no more knocking.

If you drive it around leave the Tune in there that it currently has.

Just get a few power runs done and some light throttle cruising checks.

The only shop tomorrow likley to take me charges 120p/h dyno time and their labour is $75p/h , not cheap. So i will quiz them about checking it.

Ideally i will be taking it some where else, but that some where else needs to be booked in advance, theire time is gold but well worth it.

If your in Sydney, we are having a Dyno Day at J.E.M in Moorebank for $50 and will tell you AFR, Detonation, Max Power and the tuner will let you know if you need a tune... otherwise we have a G.B for $450 you get a FULL Road & Dyno tune with print out...

Cheers

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
