with ignition issues fixed you will easily dip into the 10's and 135mph

good first effort though

yeah thanks mate.

the ignition issue was easily fixed up.

Planning on going back to track and lower tyre pressures etc....

but first I have to fix this

Attesa system has given up the ghost - error code 21 throttle sensor is le f**ked

who does work like that

what ever happened to taking pride in your work

backyard butchers

lol I don't know man.

I need to test the voltage of the attessa ecu as per the service manual.

but my voltage meter has grown legs and got the f**k out - cant find the bastard lol

id be re doing the harness.

solder my man. get that iron out. i cannot stand wiring like that even if i cant see it.

think you are right Paul

Also think that a new harness is going to have to be on order

Burn more money burn :rant:

I'd try source a new male plug w/ pins from Haltech or wherever. Cut it back and start again. Poor connections raise resistance, altering sensor readings from true. If you didn't want to solder, maybe source some weatherproof connectors like deutsch. We use them at work and installed correctly, can outlive the life of the machine in some pretty harsh environments. We prefer if possible to plug/receptacle as solder joins can become brittle and hard over time, and if there is any vibration can crack.

I prefer having an entire new harness.

However, I have just done a some quick research and found this from Haltech

the very last post got my attention

The attessa error code is still 29 even after this new tps has been installed

I wonder if something has reset itself

Got to love people butchering up the harnesses like that. Mine was the same as yours so when I switched from PowerFC to the Link I replaced the harness for peace of mind - was good that I did as I also found that the front left wheel sensor plug had melted and become disconnected :/

Do you remember changing / touching anything for the light to come on or did it just appear one day?

all I did man was remove the oil catch can from the engine bay and give it a good clean out

there was a ground wire that I thought was in the way so I started to unscrew it (sits directly below where the oil catch can sits behind / next to the battery hook) but I couldn't take it off so I just tried to tighten again (but still seemed a bit loose, wonder if there is nut underneath)

after I had cleaned the oil catch can I reinstalled with the breathers attached and went for drive

got to the traffic lights at the end of my street (600-700m or so) and before I could even cross the 4WD light came on.

Here is a quick video of the Attessa ECU flashing its goods

I count 21 am I right?

Make sure your battery and earths are good..

That's given me heaps of troubles before with my attessa

Yeah. I will check it over.

Could be so many possibilities.

What an absolute PITA.

But I guess it gives me the chance to find electrical issues that need to be resolved so probably a good thing.

Phewww.........So I fixed my 4WD issue :banana: :banana: :banana: :banana:

It was what GTR_JOEY said and was a loose / dirty ground wire which also grounded the battery wire in front of that silly catch can.

I gave it a good clean and replaced the screw with a new one as the old one was totally stripped of its thread (not sure how :dry: )

then couldnt help myself and take the car for a spin - all four wheels blazing like they should be.

Thanks Joe again for the tip.

and to all that get 4WD errors - CHECK YOUR EARTHS!

    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
