hey all, well by my topic heading, you could get the idea that my shitline crapped it self... anywho, its the air flow meter or the ECU...Im getting a mate to put it on a diagnostic tool, to find out the problem and to see if there are any other gremlins...

My question is if its the ECU, am I better of getting a new aftermarket ECU/replace the hole thing, or get a second hand stock ECU/or a new stock ECU and than get a NIStune chip-and plug straight into it???

I have a R34 GT-t tiptronic 98'

I was going to do some upgrades, like:

NIStune

intercooler kit

valve body

Turbotech boost controller

as previously discussed in another topic in here

now also Im thinking of getting a bosch Z32 80mm with a tomei plug after the upgrades that im doing..

ANYway, its about the ECU's, and if it is the aftermarket ones, which one?? or whats good, whats bad, and what to came clean off???

mate for the mods you have listed, i would probably go down the nistune road because its cheaper and easier. if your planning on building a 700hp weapon in the future, then a full aftermarket ecu would be the way to go. see what good tuners are in your area, and see what products they use/tune.

unplug the afm and if it runs (2000 rpm rev limit tho) then there is your problem

you can do this if you ever need to limp the car anywhere

When i took the plug off the afm, the car idled very nicely but as soon as i put down the accelerator it coughed, splatted and stopped... i brought a secondhand afm, hopefully it will come this week, going to put that in, hopefully it works, and than when i get the nistune, im thinking i might get a new Bosch z32 80mm AFM with a tomei plug....

How did you diagnose that it was the ecu or AFM

Well it wasnt me, its was my mate... To cut to short, i told him what happen, he had alittle look, unplugged the AFM plug, and then i started it up, it idled fine, when i rev it alittle bit, it coughed and passed out..lol

then put the AFM back on, started it up, cough, splat, chug chug.

But now, 4 days late after it has just been sittin around the engine light has come on....:banana:

Just waitin on AFM.. than ill see where i stand...

    • 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.
