yeah looks like it mate. I cannot move forward with the PFC anymore.. I have learnt all i need to know about PFC's.. time to move onto bigger and better things.

haha know that tune well, changing ecu's is always part of evolution and can only ever increase ones skillset.

My car is a car of two halves...

engine... sound system...

Reckon you can tune my subs and see if you can beat the kws I'm getting out of it? :P

just make sure that...

KW > dB

nothing worse than seeing a car with more dB than KW

that would be hard out of a skyline seeing as how the world record is about 180db...

But I'm working on it, don't worry :P

My sound system actually has 3kw of power... pretty weird to think about :D

Yeah... i got many years ahead of me before i catch you trent :P

On your current setup will you be able to go further by just changing the ECU? Where exactly is the PFC falling short?

Yes... The PFC is a great ecu. and it can do my power levels and much more. but seeing that i like to play nutty professor i need something that is more flexible to my needs.

I still love power fc's they are great. But this ecu came up and its time to make the switch, ive delayed it long enough. Hope it all works out.

ecu will be told when its in and working :kiss:

Yeah but WHAT ECU have you changed to???

We're all dieing to know, I'm surprised no-one has asked yet or did I miss something..........

well what ever it is (and ive got a bit of an idea what it could be if Dirt is involved)

you need to post the obligatry anti-lag flames out the exhaust video once uve got it all working haha

but seriously hope it all goes well,

im keen to see how she tunes up, differences you notice, and how all those new features work

ohhh i can do that now with my current setup.. Gizzmo launch controll FTW

GT from what I can see PFC's are fine for doing most of the things that users need in a programmable EMS .

I suppose more specialised uses (ALS/Launch etc) they're a bit limited but for what I want it'll do the job .

Things like the ability to self learn would be useful and I can see this feature becoming more and more important with the way emissions laws are going . If the systems can be made to self tune from basic maps then thats the hardest part for the end user solved .

BTW are you going to continue on with a mass air sensor or are you going to the dark side with an electric barometer ? LOL .

Cheers A .

BTW what system is the EPA using to analyse the exhaust gas , ages ago I remember reading that there is a method of shining a particular kind of light through the gas and by measuring the beam on the other side its possible to see the different levels of certain gasses .

im going over to the dark side mate. I am pretty sure with this ECU i can add a MAF if the MAP sensor pisses me off (this is a very good quality ecu so apparently this will not happen)

As for how the IM240 machine works at the RTA, i have NO idea.

But i do know how the machine reads, what it reads for and whats acceptable levels for whatever car.. I also know what levels are high medium and low when doing the dummy IM240 tests on the dyno instead of the guesswork i have been using previously.

Should be tuning another car for emissions very soon.

Good to see your dropping the Power FC finally.

Once you have the scope of something better you'll never look back. Id asume what ever your going to be using will be TPS/Map correction like the E11?

Generally I have only ever seen the RTA use a proper 5 gas analiser very similar to the Coda unit that anthony has access to.

    • 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.
    • 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
    • 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 
    • 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)
