I AM HAVING TUNING PROBS WITH MY SERIES 1 GTST. I WOULD LIKE TO SWAP OUT SOME PARTS TO ISOLATE THIS VERY ANOYING ISSUE MY MECHANIC CAN'T WORK OUT($900 LATER). I NEED A S1 AFM, A SET OF COIL PACKS AND AN IGNITER TO TEST WITH FOR 10 MINS. I INVISAGE DRIVING TO YOURS, SWAPPING THE BITS GOING AROUND THE BLOCK AND THEN GIVING YOU HEART FELTS THANKS AND PROBABLY SOME DOLLARS/SLABS OR IF INTERESTED A WEEK OLD UAS COLD AIR INTAKE AND O2 RUSH RACE POD. BIT OF A LONG SHOT BUT I'M SURE SOME POOR BASTARD HAS BEEN IN THIS POSITION BEFORE.

THANKS GUYS

yeah if you post your problem we could give you an idea.

but first thing to check is your plug gap if your runnig over 8 psi this should be sewt to .8 mm not the default 1.1 mm.

if the idle is bad and inconsistent ie going from 1000 rpm to 2000 rpm then your afm could be the culprit.

also the coil packs and the the ignition apmlifier if the car is running rough. the crank angel sensor could be the problem if yua re loosing power over a certain boost. factory timing should be @ 15o .

nex t I would be looking for a mechanic how knows skylines cause this guy obviously doesn't .

last one is to check the cooler piping is ok.

meggala

All pipes/intercooler pressure checked , correct heat range (7)and gapped plugs, reset ecu, Manifolds checked and tightneed, turbo removed and checked. Dynoed and mixtures seem solid at 11%(S-AFC installed and waiting for tweaking). When its warm(weather wise) it will pull through the rev range smoooth and hard in all gears, when its cold(weather wise), starts missing as it pulls higher boost even in second(high boost means 10psi in my case, no where near factory cut off). AND, fuel pressure tested under load OK and boost gauge tested as well?????? I tell ya it annoying but at least I know whats NOT wrong with the buggar!!!:D

I Have the SAME Problem as this... Cold = Miss, Hot = Fine!

I Tried a BOOST Controller and its WAY Worse (even at stock boost levels) !!! I thought it might be the Ignition module not being able to handle the extra boost from cooler air???

I currently have .75mm gap which makes it drivable... but, on a 20deg day it misses under 60% > 100% Throttle (around 4500 RPM+)... on a 25+ day it does not miss a beat...

the_tonkau: if you manage to fix this PlEaSe! let me know what it was as I am in a simular position... no parts to swap... no mechanic who knows.... etc etc...

Could be a lot of things and maybe a combination of two issues but my fix was(after lots of piss farting around, a faulty ignition module that was breaking down at higher boost! Dr Drift at BMT Motorsport (www.bmtmotorsports.com.au) found the problem!

Good luck

Steve

Needless to say it is been shaming SS Commodores and the such, left right and centre since the super mega drifto tune! Hey Dr, when you putting the NoS bottle on the BMW?...haha hehe hoo hoo....Shit I'm funny.

Easy.

No, unless you made one up out of a Sultana Bran packet, but I don't think that would be a great conducter of ..........."currents"........hahahaha !! hehe

Once again...DR DRIFT @ www.bmtmotorsports.com.au" DO IT!

Nightman,

The funny 'the_tonkau' used our last igniter module, but I still have a spare AFM, CAS, coil packs, etc if you want to try and find the problem...

The most common mis-fire problem I've seen is plugs, follwed by coil packs, follwed by CAS, followed by igniter module...

Doc.

  • 3 weeks later...

How much are all those parts to replace, Doc? I may have to visit u next time with Lucky in his Slug of a Soarer :(

I have the same problem, and only running 11psi, and getting my ass kicked @ the lights :) Definatly losing power :mad:

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
