My little project - IS200 Turbo - steviewevie - 10-01-2020
Next steps were wiring up and testing the calibration switch (a rotary knob which you can use to select between different maps on the Syvecs, switch on/off various features etc), connecting the vacuum/boost lines and starting to tidy away the wiring. A boost solenoid had been installed, to be used by the Syvecs for boost control (pics to follow once I remember to take some). On the original setup I had no specific boost control, just a mechanical valve to limit boost to around 1.0 bar. The ACIS now was fully connected to the ECU.
We were still waiting for the new air intake temp sensor (hadn't arrived due to a mess-up). The new MAP sensor was connected now, new knock sensor also (just one, instead of the two used by the stock setup), though my existing wideband lambda sensor hadn't been connected yet. Ed was hoping to drive the car around the block later that day, very exciting !

I went down to Fusion the next day to see the latest progress. The air temp sensor had arrived and been installed. My LC-1 wideband lambda was also connected now, but Ed was having trouble getting the Syvecs to see the correct sort of signals from it. So unfortunately that meant no driving (and no dyno) yet, until the problem could be diagnosed.
Good news was that the fuel gauge seemed to be working fine, despite me expecting that to be tricky based on some historical examples. There were quite a few warning lights on the dash, e.g. ABS, TRC, oil level. But I wasn't too concerned about that, since there may well be other wiring needed to still to make various sensors happy.

Love the detailed process mate!

Excellent updates very detailed keep them coming lol

Thanks guys, glad you are enjoying it. Luckily I tend to keep quite detailed notes for this sort of thing, otherwise I wouldn't be able to remember most of those little bits and pieces ! We hit plenty of problems along the way, and I'd much prefer to tell the story with those in too, rather than pretend it was plain sailing.

Next day, I spoke to Ed on the phone. The lambda sensor was now working correctly, it had just needed re-calibrating. Ed had driven the car around the block for the first time (his workshop is on a weird/interesting ex-defence research site, which is now full of special effects film studios !). He reported that the coolant gauge on the dash wasn't working, which suprised me a little since I hadn't expected the stock ECU to play a role with that.
The central locking was fine now (previously there was a weird delay), he had found a module behind the dash which hadn't been plugged in - a lot of stuff had been taken apart ! He thought the drive-by-wire didn't feel right, but again that's something we expected would need some trial and error, e.g. the Syvecs needed configuring as to what pedal position produced what throttle response.

As I think I have already mentioned, it had become clear that the stock immobiliser on my car would no longer work with the stock ECU removed. So I had a look into third-party alternatives.
What I wanted was a basic alarm/immobiliser that was Thatcham Cat 1 approved (insurance company requirement). After speaking to Rabster (thanks !) I narrowed my choice down to one of the Clifford alarms, e.g. the Clifford Concept 650 MKII or Avant Guard 5.5, or alternatively the Toad Ai606.
I didn't want a proximity sensor/text/remote start/tea-making facilities, I just wanted to keep it simple. Also something reliable and with a good reputation, the last thing anyone wants is the alarm going off in the middle of the night for no reason.
I ended up choosing the Toad alarm. It did exactly what I wanted, I couldn't find any complaints on the Internet about it (when it had been installed by someone who knew what they were doing), and I found it for a very good price (less than £100). Also, another big factor was that I was able to get hold of the installation instructions for it, with the Clifford alarms I'd have to get it installed by one of their installers - nothing wrong with that per se, but it would be nice to have Ed install it, so no chance of any finger-pointing if the alarm installer had problems with the new ECU and vice-versa.

I mentioned a while back that Ed thought I'd have to get a registered installer to fit the alarm to fit in with insurance company requirements. But after speaking to a couple of insurance companies I found that although this used to be the case, things had changed, and now basically anyone could install the alarm, and it was just the alarm itself that needed to have the certification.
More on the Toad alarm install when I get to that point (soon !) - quick summary = I'm very happy with it.

That's interesting news about the alarm!
Wonder of that helps us with the keyless entry system Rabs!?

Sparkystav That's interesting news about the alarm!

which bit the alarm certification that is correct the governing body that issued certificates went bust or similar, as such now insurance companies dont require a certificate proving the alarm was installed by a registered fitter.
the alarm does need to be category registered however. for example the new Keyless systems i am looking at are cat 2 but can be used solely as the keyless entry and linked into the existing car alarm or even a CAT1 alarm like Toad or Clifford.
remote start is still a grey area due to its nature however.....

Toad Ai606 is the alarm I had in the MR2. I found it pretty easy to work with and add extra features like popping the lights up, boot release, total closure etc. As you say, easy to find the wiring manuals for it.
