Fair bit of progress today... Injectors and Coils are wired in and all the sensors and factory wires terminated to the ECU... Just a few loose ends to clean up and see if any magic smoke escapes..

Cheers James do eet!
Another fun feature is the scope mode which basically turns your ECU/PC into a Digital Oscilloscope. Pretty useful for making sure things are working how they should (in this case crank and cam triggering)
And this is a little behind the scenes video Jason made of what the advanced view looks like in the software and some nice little logic he wrote to show some fault conditions.
As you add logic in the advanced view it is created in the simple view with the user definable inputs and thresholds and settings that are adjustable. It's pretty crazy..
I can see this being over pretty much most peoples heads, but for the nerd enthusiast its mind blowing to have such control and freedom in I/O and logic.

I noticed you've got the same coil setup as I'm running too! I've not been able to put mine through it's paces yet, given it's un-tuned! But i'm hoping for cleaner spark, better AFR's etc.
Looks like a heap of features you've got available to utilise! I'll be using a PS2000, and not sure how it compares to your Adaptronic. Similar goals though, all I'm really after is a responsive 300rwkw car
Your turbo choice looks good! Coming along nicely with the steering wheel and the Supra 17's too!

You have the same goal as me James, the coils seem great so far as far as fitment and neatness goes. I had no problem with the factory coils though and just went these to get rid of the ignitor basically..
I decided to go the untested/hard way, sometimes I wish I had just gone the normal/proven way that you have, but hopefully it pays off..
It will be a good comparison between our cars. Make sure you get a boost vs RPM plot instead of km/h!
The ps2000 is great, as are most of the high end ECU's these days, this one is just a bit more nerdy.
The factory air temps sensor is an excellent manifold temp sensor so I wanted to try to get a caged/open element sensor in there so see if it suffers from the same heat soak.
I couldn't find a m16 sensor so I made one by removing the thread off a NPT one and boring out a speedflow m16 adapter!
If it's just as rubbish as the stock one i'll put one in the intercooler piping where it's a bit more isolated.
The car is running and has a bit of a road tune in it, but there is still a fair bit of setup and fine tuning to do.

So after what seemed to be a never ending list of issues I finally managed to get some dyno time to see what the old boat could do.
I was unable to detect knock properly on the ECU so had to go old fashioned and I ran into a weird surge issue on higher boost that I haven't solved yet.
I'm not sure what ramp rate 'shootout' mode uses but we used 80 for most of the load tuning and 160 for the final pulls which made the turbo look less responsive than it is, but I have no issue with the response. It was reaching 19psi at like 3,200rpm.
It would be interesting to see if there is a difference in 6F shootout.
Anyway, this has consumed most of my time for the last 6-8 weeks and I'm just going to relax and enjoy it for a little while before I do anything else.
Second gear spins up the 265 semi slicks at around 4 grand and it is pretty rapid.
There is more headroom in the turbo output as the max RPM was 132,000 and the limit is 150,000.
There is still a huge boost drop off on just spring gate pressure but max duty cycle on the boost solenoid to hold boost to red line was around 50%
More boost and timing with some water meth would see the most out of the turbo.

Since my last post back in July last year the Soarer has been off the road in the garage getting covered in dust with no brain.
After weeks (months) of trouble shooting dozens of weird issues and simple things not working I lost faith in the ECU and decided to pull the pin.
While amazing in it's 'feature set' actually using it is another thing. This is not your normal 'top of the line' ECU. It is a no holes barred development ECU that can really do amazing things if you are a PLC and logic guru. I am not.
A friend of mine is running one on his 34 GTR and integrating it into the ATEZZA system and multi function display etc, and he has re-written much of the logic. That is the target audience.
So from one extreme to the other after 6 months of not even wanting to look at the car from frustration, I have decided to give her the 21st birthday she deserves.
I have been collecting parts over the last few months and have been taking the time to do it properly without deadlines and worrying about having a driving car after the weekend which was much less stressful and enjoyable.

New Brain!
While referred to as the iPhone of ECU's, the elite 2500 does everything I want to do out of the box and has a very polished and clean user interface. Within minutes of opening the software I had setup every feature I wanted the Adaptronic to do.. For example knock. Select an input on the Adaptronic for knock and you have to 'build' the logic to actually do something if knock is detected. With the Haltech, all the spectrograms, filter frequency, background noise level, protection method options are there..
This has been the resting place for the last 7+ months.. A co-worker bought a 1.5J Soarer and I was helping him sort it out (it got an elite 2500 too)
New harmonic balancer, Timing belt, Billet tensioner bracket. 240 lb/ft
I have done the timing belt before and used the starter motor method to undo and 2nd gear handbrake method to do it up.
Just buy (or borrow) the tool... It makes a prick of a job a breeze..

While on the subject of knock, there is a great write-up on efi101 about the Flat vs Resonant knock sensors. Long story short, resonant sensors are fine, but they may not be listening to the right frequency.
http://www.efi101.com/forum/viewtopic.php?t=7972
Wiring the flat response sensor for the elite 2500
Stock 'resonant type' front knock sensor (power steering pump removed)
Rear sensor (and the fuel rail damper that every supra owner deletes for some reason...)
Modified stud to adapt the screw in resonant sensor to the flat response sensor.

I had a bit of weeping from the power steering pump for a while, so I got a re-build kit from toyota for about $30..
I'd never pulled apart one before, but there was nothing super complex to it.
It's a cool little vane pump, just keep everything together and you will be fine.
The kit came with every o-ring, gasket and seal for the unit. The only thing I had to buy was a new bearing from the local shop for $5 for piece of mind.
I also pulled down the starter motor and gave it a good clean out as it was hanging on engagement on some cold mornings. There was a huge amount of crap in the commutator section! A couple of hits on the 12v and it was running smooth again.

I got a full set of Supra Bilstein's for $175 delivered to my door and set about swapping them all over.
Rear comparison.
They are much lighter, but I guess a fair bit of that has to do with the king springs larger amount of spring coils.
It will be interesting to see how they go.
I managed to change the fronts without disconnecting the upper control arm. By removing the lower shock mounting point from the lower arm there was enough wiggle room to get it out.. The whole car only took a few hours to do and was quite straight forward..

Niice! Good to see the motivation came back buddy. I'm clearly still lurking on occasion and miss tinkering in a big way. The wife's yaris (although absolutely brilliant) just doesn't cut it sometimes haha. But still tows my tinny well and has a decent set of HID spotties now for good measure up here in the Snowy Mountains :-)
