I got an R34 Gtt and sometimes after gear changes the "slip" light flashes and power is limited for a few seconds..

i have searched forums and could trace it down to the coil packs.. when i bought it the guy said they had been updated..

just wanna check/confirm it is the coilpacks.. all searches in forums seems like others have the slip light stay on.. but mine flashes for a few seconds then goes away :S and no other lights come on.. could this be the same prob?

cheers in advance

It could be a range of issues (e.g. bald tyres, weather), what makes you think that the coil packs could be causing the traction control system to engage? What happens when you disengage TCS does the problem go away? Because the easy solution is to grab Dan666's TCS bypass module.

nah tyres are fine (not new but fair tread).. normal qld weather not raining or anything..

i will have to test with tcs off.. brought it down to coil packs as this seems a problem in r34.. however my problem seemed a little different from the others i found in the forum as my slip light flashes for a few seconds only and doesnt stay on? this only seems to happen on gear changes (not all the time).. usually when i come to change down a gear..

may not be coil packs which is why im asking but seems the genuine response with similar problems..

cheers, will test with tcs off and post results

I'm still not sure what the correlation between coils misfiring between gear changes and the traction control system is.. but yeah try it out and post back the results.. i'm really curious now. Can you give us a run down of modifications?

if u have ur tcs on, then what ur car is doing is normal...probaly when ur gearing down ur rear wheels are spinning, so traction control does its job and kicks in, limiting power and making the car feel dead for a few seconds...

turn tcs off and u well no longer have this issue...

hey guys.. yeah jeffboyracer that could be the thing.. i mean it doesnt start spinning but quite possible and im jus freakin out :( it doesnt do it when traction control is off.. yeah suspension is pretty stiff.. as for engine modifications it's got:- brass button clutch, greddy intercooler, 3inch turbo back, oil cooler.. i have a power fc but not installed yet..

i wasnt saying it was the coil packs.. that jus seemed a main problem with other slip lights

cheers

Exactly - drive any modern car with a TCS system - they all flash when they intervene. Its normal.

yeah well i've had a commonwhore wioth no tcs.. was strange cause i didnt think it would kick in as the revs wasnt that high.. then word on the forum was the original coil packs are shit.. wasnt sure.. but all sweet it seems.. will be goin on dyno within couple of weeks for the power fc

cheers for the advice anyhow

yeah happens moe than i think it should.. i just turn it off cause it works when it's not required.. that was the problem.. tcs thought i would skid.. or whatever and activate.. i turn it off and never get any problems.. more kick out of it too...

had tcs on in the rain the other day.. with brass button clutch.. nasty.. wierdest shit i've felt.. 1st gear..

As everyone has said, it has nothing to do with your coilpacks. They only provide spark to the spark plugs... not interfere with the whole drive line. TCS kicking in is a normal thing that happens when your driving breaks traction to stop your wheels spinning and unnecessary tyre tread wear. Yes it does feel weird, but this feeling would be enhanced by the stiffer suspension and your brass button clutch probably isn't doing you any favours either. But thats why you have that little "fun" button under the steering wheel, so you can tell the car that "No! This is how i want to drive... i like wheel spin dammit!!" :D

right on sleepr85, press the 'fun' button!!!!

I think crappy or bald tyres are a much more likely cause thanks coilpacks?? the weather is pretty shit this time of year so it's not unusual to get wheels to spin if it's wet and/or the tyres are crap as previously mentioned.

i got bridgestone 255/40/17's they not crappy either.. and the shit thing is that with tcs off and doin the EXACT same thing with driving i got no wheel spin.. no loss of traction.. nothing.. jus like normal driving.. that's where i thought there was an issue.. i think as it was suggested that the brass button clutch does me no favours.. especially in the wet.. tcs sucks when taking off with the brass button.. cause you gotta give it some..

yeah thanks howie.. i will do that.. i didnt know there was such a gizmo.. cheers

    • 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.
