Ignition Problem

Hey everyone

the problem I have I think is something to do with the ignition. Last night i attended the Vic bush fire cruise in Perth, and i hit rev limiter but didn’t stay on it for long and changed gear, however after that my car is popping really bad and it kind of struggles and looses power at times, this happens between the rev range off 3400rpm-5000rpm and then usualy clears out but then i can’t go past 6000rpm coz it just keeps bouncing off like a rev limiter would, however at these rpm’s the noise it makes is louder than normal and a lot of people said it sounded as if it had antilag( trying to put it in content to describe it better ), as time went by it got worse and worse so i decided to drive it home, while it kept miss firing like that, but just dropped into a higher gear and kept at about 2500rpm and drove it slowly.

Today i took it for a drive and it seemed fine, until the car warmed up and again bang bang bang, in every gear around the same rev ranges, so i took off the air flow meter and cleaned it, also took the coil packs off and cleaned them and inspected them for any crack's or something out of the ordinary. After that i checked my spark plugs and changed them, just to make sure it wasn’t them (gapped at 0.8), i took it for another drive and still the same problem keeps occurring. it’s become a bit worse now as even now on idle it’s miss firing, where before idle and in neutral it didn’t seem to happen.

Does anybody know what else it could be? or what else i could check? Could it be because my ecu i have is stock, and still hasn’t been chipped and retuned for the mods i have?

This issue only started last night, its never happened before and I’ve been running the stock ecu with those mods for about 2 months..

The car is a R32 Gtst with the standard Rb20det

The mods i have on the car at the moment are

- Pod Filter

- VG30 turbo (single turbo version)

- FMIC

- 3 inch exhuast

- Stock ECU

and thats about it for performance wise.

Any help appreciated.

Thanks alot, niran

sounds like coil packs, they must be stuffed tho to do that?? dunno if bouncing it off the limiter could kill them like that?

swap them with a mates and see if that fixes them

hey mate, thats what i was thinking too. maybe i will do that and just borrow some and see if it fixes it.you reckon it could also just be the stock R32 gts-t fuel pump? dying out because off the other mods?

To update this thread my problem did arise again after the fuel pump.. and i did find the problem so incase people do run into it again. my crank angel sensor connector had broken and one wire was not in the clip causing it to stuff up..

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
