Haven't got a car to look at just now but I think you need to pull up the plate at the bottom of the door and pull the door rubber back to remove the trim to get at the ecu and there are a total of 2 or 3 I think nuts to remove. Then undo the 10mm bolt in the middle of the plug and pull the plug out and then remove the ecu.

That looks like someone has done that so it can't be removed.

Yup.  Looks like the nuts have been ground down in some weird arsed way.  Your best approach would be brute force and violence.

I'm with him.  PFC is a f**king terrible idea in 2018.  Was a terrible idea in 2008!

I did this job in my 34R, yours has been modified incorrectly - As those should be 10mm bolts. 

You will need to brute force those pop rivets/shear bolts? as gently as you can to not damage the underlying bracket. 

As mentioned, it would be much better to use something newer. I had decent results with Haltech plug in, but there's lots of options. Ideally something that removes the AFMs if possible. 

If that's not an option, choose your tuner carefully as PFC+AFM has been known to result in various drivability issues. Ideally only use it for lower power goal.

Good luck.

 

 

There’s a few ways to get them out,

you can cut a slit through the middle and use a screw driver,

you can file 2 flats either side of the head and use vice grips to turn them 

or you can use a center punch and hammer to turn them

18V angle grinder and just remove the bits that annoy you!

just wanted something cheap to try stop it from running ridiculously rich on 98... currently get maybe 185ks out of a tank

Car is no good if the ECU can't be taken out, will give you $20k for it as is.

ahaha two hours ago when i was still struggling to get it out i would have accepted that

i live in perth any recommendations for a good tuner? i don't really have a power goal in mind i just want it to run smoothly on 98 and reduce the black soot on my poor white car

Vice grips were the way to go, could slit it wide enough to crack the loctite

Sounds like a problem that could be either:

  • Faulty AFMs
  • Wrong Injectors installed
  • Stock O2s are rooted

    • The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow 
    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
