Do you have any form of aftermarket CDI? eg HKS Twin power?

If it is indeed your alternator then it's not a massive job, though i've never had one fail personally its bound to go through enough wear and tear to eventually give up.

yeh but wouldnt that like turn the car off... make me loose lighting and make my headunit play up aswell??

or is there like a seperate part which runs to the ecu..

most of the times the battery light will come on, on the dash, or it will have a loud wurr to it... and the charge rate will drop to battery voltate eg. 12.6 or 12.8. if diodes are gone charge rate my be normal but untill you put lights ect on, will drop down to 13v or something... never realy seen one have any problems with supplying spark, cuz if it gets spark ecu is doing its job... how well known is your mechanic? as might be time to change... never seen an alternator do anything like what your sayen on any car.. weather it be ford, holden, nissan, subaru, mazada, ect..

i had the same symptom you have when i had my air flow meter disconnected, only as i had to get home, only with the airflow meter hooked up, it cut out and ran like shit.... my problem was that my engine was farked after it was majorly overheated but ran fine 70% of the time rb25det s2 though? dunno what yours is havent read your updates

hes just a normal mechanic down the road from me. not a specialist in imports or anything. I dont think its the alternator... i really dont, but he has one of those Snap-on error detector thingos, and its readying a problem with the signals to the ecu or sumshit... so im not to sure wats going on, if this doesnt solve it ill take it to marty when hes off holidays. Probably a good thing i changed the cam angle sensor anyway, its was sooooo f**ked haha both bearings where ceased and the disk and sensor where both f**ked.

i kno its so fkd. I havnt tried the ecu thing yet, would one from a rb25de neo be the same, i got a mate with a 34... or one from a rb20de?

are they all simular?

update: he said it is the alternator playing up... now i dont see how this would be the case, he recons it isnt giving enough to the computer or ecu, and that isnt able to support the igniter pack and all that... wtf?

i was checking ur gtr out today daz :rolleyes: cus my cars at yates automotive across the road there.

yeah, well im sure the ecu's are model specific, so i would try find somebody with an n/a RB25de r33/r32 (depends on what model your motor is) and try there ecu if u want to try that. but yeah unless you have diagnostic equipment to plug in, your just going to be guessing if its something more serious then all of the things i have described.

yeh the mechanic is using a snapon computer thing. If he cant fix it with this alternator thing he recons it is, im ganna go thru the elemination process on the smaller things, like loom, afm, so on as you said daz but then if im still lost ... ill take it to a specialist in this area.

i just spoke to my old boy then he went and saw my car today when i was at work.

the mechanic said when he disconnected the alternator... the missfire wasnt present... car went well, when he hooked it up there was a miss.. he said the alternator is working but having peaks of power. and the ecu is like wtf? and losses it for abit, that when the problem comes ... but stil im not convinced.

Also the miss gets smaller and smaller the warmer the car gets.. he redlined it today after it had been running for awhile, and there was a very minor misfire at like 6500.... when its cost it can rev over 1500-2000 without jerking around.

WTF i just wont this shit to fk off haha

ok legend... sorry i didn't know it was a spelling test/English lesson, next time ill be prepared for hilarious sarcasm.

Like 90% of the comments i see from you are all pathetic sarcastic calls mate. legend..

Brad!!!11!!11

Can you pm me your mobile number please?

I'm Trying to work out which turbo set up I want and I'm looking at a 3582r in .63 housing

Just wanted to talk to you as I believe you have the same set up??? And see what your thoughts on it were. :blush:

WooHoo!!!!! I got my full open bike licence today!!!! I have been out riding for about 3 hours on my cbr600 and my ass is killing me hahaha. Awesome though.

If anyone is keen for a run up the hills or something let me know!

*cough* brad *cough* :D

    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1680, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.
