My little project - IS200 Turbo
Ed was already firmly of the view that standalone was the way to go for me. He recommended the Syvecs ECU (specifically the S6GP), which possibly does way more than I need (see http://www.syvecs.com/s6gp.php and http://www.syvecs.co.uk/downloads/Syvecsfeatures.pdf for more details). A big advantage was that he had good local support available for Syvecs, from the developers of the ECU themselves). And the fact that Ed was local to me was also a big plus - e.g. easy for me to pop in to see how things were going, and to pop back for fine-tuning once the work was done).
I am not trying to say Syvecs is the best full stop (that wasn't the objective), but it seemed the best option for me.
Although to our knowledge Syvecs hadn't been used on an IS200 before, Ed was confident that with stock wiring diagrams available for my car, and the fact that it had been used on various Supras and other Toyota engines, it shouldn't be a problem.
The plan was to remove the stock ECU completely, since it would no longer be required, and get any other little bits (gauges etc) working as necessary.
After much thought, I decided to go for it. I felt that the existing issues took too much of a shine off things for me to enjoy the car as it was. I bit the bullet and we arranged some dates (summer 2011).

05-01-2019, 06:01 AM #1,231My e-Manage Ultimate had already been remapped by Ed from Fusion Motorsport in Surrey, to good effect. Ed has experience in a wide range of ECUs, both piggyback and standalone. So I decided to get his advice on this. Because he works with so many different ECUs (often a different one each day !), I thought he could give me some unbiased advice, and wouldn't just have a single product to consider.

As I go through the updates, you will see how well/badly we did against this list.
In no particular order :
- Fuel gauge
- VVT-i
- ACIS (flap inthe intake manifold)
- ABS
- Aircon
- Wideband lambda feedback
- Knock sensors
- Electronic throttle
- Traction control (expected to lose stock version)
- Alarm/immobiliser/deadlocking
- Economy meter (expected to be lost)
- External temp gauge
- Rev counter, speedo
- Odometer
- Water temp gauge
- Windows and mirrors
- Rev limiter

05-01-2019, 06:13 AM #1,232Here's the big list I made of stock functions on the car (plus a few bits added on with my turbo). This was for me to keep track of getting all of these (or at least most of them !) working with the Syvecs. Some of these are pretty mundane things, but I didn't know for sure with some of them whether the stock ECU might have a role or not.

Sorry if this seems a bit odd/slow, I want to try and post up all the details almost as if it was happening now (i.e. telling the story of what happened and what problems we hit along the way). I appreciate that most people probably just want to know how it is right now, but I will try and bring things up to date very soon !

05-01-2019, 07:26 AM #1,235It's going great Dan, thanks. Yes, had it dyno'd with the Syvecs. I am going to update this thread with the Syvecs install details (I made lots of notes as it was all going on). I have a few photos but not many, as the work was mainly wiring and mapping, so not many physical things to photograph. I will post up the dyno graphs when I get to that point in my "narrative".

The Syvecs ECU has drive-by-wire capability, albeit via and add-on module. Ed made up a custom loom to connect everything up. Ryan Griffiths (of 2bar Tuning) was also involved, and the view was that the wiring diagrams looked 90% the same as a VVT-i Supra, so the wiring should be no big deal. ABS looked different, so Ed aimed to take signals for that direct from the ABS ECU. The plan was to get the core stuff working, i.e. the engine at least firing up and running under the Syvecs, then work on extra bits as per my list a couple of posts back.
Here's the wiring loom in progress. The white wiring is the new loom, the coloured wiring is the stock stuff :

On this one you can see the Syvecs ECU connected to the new loom, and sitting inside the stock ECU box :

The drive-by-wire module is the little circuit board, connected via yellow and white wires, visible in this pic :

Also on that picture above, you can see the new MAP sensor has been added, bolted to the side of the stock ECU box (with the red hose going into it). I already had a GReddy uprated MAP sensor for the e-Manage, but this wasn't compatible with the Syvecs, so a new one was installed.

06-01-2019, 05:09 AM #1,236One of the first questions regarding the Syvecs installation was where to physically mount the ECU. With the stock ECU being removed, the obvious place was the stock ECU box in the engine bay. This was checked and it would indeed fit with a very minor internal modification, so we went ahead on that basis.

At this stage Ed noticed that my intake air temperature sensor (the stock one) had been left dangling in the engine bay all this time (i.e. since the original turbo conversion). I had noticed this but just thought it was an unused plug, I hadn't realised it was an actual sensor and was still being used by the stock ECU ! Maybe this had caused some problems before ? Who knows, oh well. The sensor needed plugging back in somewhere, but we decided to replace it with a generic air temp sensor, since the stock one had no thread and a threaded fitting would be easier to install somewhere appropriate.
After more work by Ed,he got the engine into its proper 720 mode. VVT-i seemed to be under full ECU control (it has its own map), and the drive-by-wire module also seemed to be working (e.g. you could see it working the throttle body motor).
The new MAP sensor (see pic in previous post) was connected, and my existing LC-1 wideband lambda sensor/controller was connected to the Syvecs.
At this stage there was lots of stuff still to do, but progress was being made. Always nice to see the engine running rather than just a silent spaghetti of wiring !

06-01-2019, 07:01 AM #1,238Once the initial loom wiring (i.e. not all the ancilliary bits) was complete, it didn't take long to get the engine firing up. Initially, it would only run in "360" mode though, not the proper "720". My understanding on the intricacies of this are limited, but I think that meant it was firing the ignition every revolution of the crank (360 degrees), whereas it should be doing it every 720 degrees (2 revolutions) as normal for a 4-stroke engine. The Syvecs ECU expects to see certain stuff happening and it wasn't completely happy. Ed suspected that this was down to cam settings.

Yes
All will be revealed when I get the story up to the dyno stage, then I will post up the graphs
