My little project - IS200 Turbo
toxo Who says you can't do both?
Waiting for details Stevie...
Most people would run both, I think. Though Steve mentioned the stock ECUs being REPLACED. I think that is what Dan was questioning.

I will post some proper updates and pics when I get a chance. Dyno graphs too. For now, just to clarify, yes the stock ECU has been removed completely, and I have a Syvecs S6GP running everything.
Gauges were fine to get working again, except for the water temp gauge, so I have a Defi gauge to give me that info. Fuel gauge and rev counter were no problem.
The stock immobiliser is operated through the stock ECU, so I had to install a third party alarm/immobiliser to be compliant with insurance requirements (i.e. my insurers need me to have a Thatcham immobiliser).
As I said, I do intend to post some proper updates and full details, along with issues that were hit and solved along the way. Just wanted to answer some of the questions raised.

As you will see from some of my previous posts, my turbo install with the e-Manage Ultimate was sometimes good, but sometimes irritating. This wasn't the fault of the e-Manage, but more an issue of it being a piggyback setup. The e-Manage was setup with a perfectly good map (well, two maps actually, see my previous post about switching between two maps on the fly), but sometimes it seemed like the stock ECU decided to do something a bit different, and the e-Manage couldn't cope with that (nor would any piggyback ECU).
For those not familiar with how this setup works, what the e-Manage was doing was sitting between the stock Lexus ECU and the engine. So when the stock ECU called for a certain amount of fuel, for example, the e-Manage could adjust this and put more/less fuel in. Similarly with the ignition timing. But with a fixed map, if the stock ECU changed its behaviur, then the e-Manage would just carry on as normal and suddenly things could go a bit weird (e.g. stalling or running a bit rough).
I had been trying to just live with the issues, but I decided to investigate the options for a standalone ECU. A standalone ECU would have full control of the engine, with no interference from elsewhere, so it should be able to provide a more driveable solution. There were potential downsides though, not least the cost/complexity/time for such an exercise. Was it really worth it ?

05-01-2019, 01:14 AM #1,227Right, time to get the ball rolling again here. I am going to bring this thread up to date with the work that was done on my car last year, plus what I am doing it to the moment (other stuff than the ECU).
