Cmon Ron. Hurry up and get your timing right so you can go back to not fixing the bov return.

I bought one and it bolted up to my stock airbox going to a 4" snout of a Hypergear SS2. However, I liked pigeons and tuuurrkeeys more so I installed a pod filter to attract slarts & cops.

Micko Atleast knows where his timing is sitting... Just saying.

Adjusted my cas to 20degs base timing with TPS connected- see how it drives tomorrow.

I can't believe you haven't specified in that sentence s what timing the power fc was displaying! (Actually I can believe it)

Me too. But thats where the cas was before, and also when I did the belt early this year thats where I set it at 15 but had Nistune. Remember this is 20degs now with TPS connected as suggested by some of you this morning (since power fc). TPS disconnected reads 25ish.

Funny thing when I disconnected TPS then reconnected with engine running it went to 15 instead of 20. Then turn engine off, tighten nuts, then engine on and it went back to 20. Very sensitive to even slight taps of rotation.

Isn't this why some tuners turn the CAS all the way advanced or retarded and then compensate for it in the ECU? So people can't just spin it willy-nilly and adjust the timing?

Seriously? Do you not get it yet?

What the power fc says it is putting out at idle is what the cas should be set at. You need to check that.

No way slightly tapping the cas or doing up the bolts moves it by 5 degrees. Unless you are totally ham fisted. It's the power fc putting out different timing. Not the cas moving. Unless ofcourse you are completely undoing all the cas bolts while adjusting them which is just bad practice .

This thread us unreal. Just the recap you aren't bothered with the one initial problem in the the thread only because you caused another more serious issue.....

Who knows. But the amount of guys doing random shit with the hand controllers is surely concerning to them. Now I know why tuners lock their tunes.

FFS Ronald a month later and 18 pages of nonsense! Give up and get the car to some kent who knows what he's doing! ;)

I know/understand you're a tight kent & can also understand that you are trying to learn/troubleshoot on your ride but the money you have lost in bad fuel economy probably could have paid to have had your car sorted by now!

thats what i'd call lazy tuning.... 'edit' took the wrong quote....meant to respond to this one. Isn't this why some tuners turn the CAS all the way advanced or retarded and then compensate for it in the ECU? So people can't just spin it willy-nilly and adjust the timing?

You seriously sound like your on your monthly periods sometimes..while other times you can be helpful,...I have seen your posts on other threads..and seen others give you a bit of a rub-down...

Lol....and life goes on. Let me play with my car and you play with yours right? If you can help then you can be sure its appreciated, if you start having your periods then I might just ignore ;-

I think he is trying to be helpful by stopping you from blowing up your engine.

Mick I dont really care about the bad economy as long as I'm learning stuff and am able to fix it myself sometime, that is highly satisfactory to me. Even if it goes backwards n costs more in the long run. Part of the fun is learning, DIYs, fixing, enjoying, for me that is. Does that still make me a tight kent??

Calm down champ. Read back over what I have written, if you have the time.

This thread is really interesting and gets funnier as it goes on. Any moment now you are likely to pop your engine..

You say you want to learn about your car and buy tools etc, but won't buy a wideband and datalog it which is mandatory if you want to actually achieve anything rather than just taking wild guesses.

Remember the part where I said if your afm is dodgy your car is tuned for it? Do you get what I mean by that? If you did actually try someone else's afm you could very well kill your engine if not monitoring afr's.

Anyway man, keep this thread alive. Its interesting to See how long untill you either fix the actual issue or kill the engine.

This is exactly why I do not have a hand controller for my PFC

      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.

      After market rear camber arm adjustment

      By Duncan · Posted

      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

      After market rear camber arm adjustment

      By V35Newbie · Posted

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      After market rear camber arm adjustment

      By Duncan · Posted

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      After market rear camber arm adjustment

      By V35Newbie · Posted

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
