oh i thought you'd change the coilpacks already....

the #1 place to check first is coilpacks. Get splitfires if you need to change them.

Does the car sound audible different when you hit the flat spot? any engine check lights come on?

OK -

CAR IS STOCK - Only pod and exhaust put on, No coil packs nothing>

Now my mate said all his skylines he brought has done the same thing,

APPARENTLY spit fire coil packs are the answer.

It has nothing to do with timing belt as the belt had just been replaced 4 days ago. and major engien service.

No engien lights are coming on.

When it hits second stage boost, the rpm tacho goes mental. ( showing mis fireing ) this i belive is due to SHIT COIL PACKS ( standerd)

I am buying spit fire ones to solve the whole problem.

Hope it works.

I don't think you understand, it could have everything to do with the timing belt being changed if they've skipped a tooth during installation.

Get them to check that first. The try the other suggestions if that fails. Generally if you start having issues after you've just replaced a part the best place to start is looking at the part you just replaced.

You didn't say anything about misfiring before...where was that gem of a symptom when we needed it :(

so n that case do u think it may be coil packs? ive been advised by a mate who had very simalar happen to him on both his gtst and his new gtr he said he just changed coild packs straight up and works a treat now.

whilst it's a very good idea to check the timing, there probably isn't any harm in changing the stock coilpacks anyway. Yes some peoples last, but you'll probably need them sooner or later anyway.

Paks.

The taco jumping around is a dead give away.

Get yourself some new coil packs. JJR (Just Jap Racing) coil packs are about $100 cheaper than Splitfires and have had many good reports. JJR are traders here - find them int he Classifieds section.

Yeah if you can afford to do so, change the coil packs regardless of what this issue is...they fault down the track even if they aren't responsible for this. But I suspect they are...

You have a choice of:

Splitfires

Yellow Jackets

Just Jap Racing

There's a few other brands floating around too but the above have been used pretty widely on here with good results.

Make sure they hooked up the cooler piping tight aswell, as a leak will make it run rich and miss if they touched it. Also check turb boost line, Map sensor line and bov line.

Does it miss under non boost accel to the redline?

im looking at used spit fires or brand new yellow jackets.

um i donno it idles funny, then when boost kicks in it cuts out after 4500prms, then run like ass untill 6000rom and then boost kicks back in again?....

i donno i havent even taken the car in to get checked up it so ill figure it out.

its got stock cooler piping but i guess i shall check all hose clamps after i get my coils.

All vaccume lines and press lines including BOV seem to b in good condition and all conected properly.

It just feels like the engien is not fireing properly. or not breathing properly.

think ill get coils done then timeing re done and go from there, im prety sure it should solve the problem.

if your coilpacks are shagged, they are shagged all the time on boost

ie they dont magically work between 4500rpm and 6000rpm and then misfire city

when coilpacks are shagged it will misfire its ass off from like 3000rpm to redline (any amount of decent boost)

given you mention the typical flat spot / cut range for R&R id say check the basics

given you said youve only just had the car

it could be

a) it started since the service / timing belt,

or b) its always been shagged

so check the basics, check it with a timing light at idle, check to make sure your base timing is correct

reset the stock ecu, perform a stock ecu diag if you can with consult to check for any dead sensors or unplugged sensors

best thing is just to check in with a reputable workshop asap - patto i assume is patterson river, so take your pick of say Chasers east, RE Customs etc.... I'd def go to Status but they won't be back until 30th August, and i take it you'd probably want it sorted by then.

and IF you do need coilpacks, DON'T muck around with the other brands - just get splitfires.

Why do you keep saying this? Have you had a bad experience with other brands?

Yeah I gotta ask, do you work for splirfire lol? They aren't the only ones who know how to make coil packs :nyaanyaa:

All coil pack brands (including splitfire) have had warranty issues, and from what I've seen replaced them for the customer without hassle. YJs saved me and a few mates $200...

:nyaanyaa:*************PROBLEM FIXED PEOPLE!!************* :P

Issue; AFM, Was corrupt. Replaced with new one- CAR RUNS PERFECT>

Thankyou all for ur suggestions. In future any further problems i know where to start looking!

Damn it!

Sounded like coilpacks to me :nyaanyaa:

Glad you got it solvered :D

Exactly, I am using Branz coilpacks they work great, about 15 months of use thus far no issues with 270rwkw.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
