Anyone running a 996 on standalone engine management?

Does anyone have a 996 on standalone engine management? If you've kept the standard dash functionality i'd like to know how you've done it, wiring directly from the new ECU or going through the original ECU.

Talk to Nxi20, Nick. He has Syvecs so can fill you in.

Thanks, i've just sent him an email.

The Syvecs replaces the Bosch ECU entirely - I have the latter sitting on my parts shelves. I guess that the trick is making the loom that joins the original ECU connector to the Syvecs one. Syvecs supplied mine and everything just works. The only slight problem is that the fuel consumption reading is way off (about 40% less than reality) but who looks at that stuff anyway? The important stuff like the fuel gauge, rev counter, water temp & speedo all work fine.

What the benefits of doing, please? Is the Bosch system flawed/limited in some way?

[nxi20]

The Syvecs is far more modern & sophisticated compared to the Bosch ECU. It really comes into its own when you are significantly modifying the engine &/or exhaust away from standard. It can be configured to do things that provide useful engine protection - for example, mine is set to not fire the coilpacks unless the ECU sees 2 bar of oil pressure, limit revs if it sees water temp below or above a set limit etc. For turbo applications, you can have multiple switchable maps for different conditions or fuel quality. It also data logs automatically which can be useful when testing changes to a map in real world driving conditions.

Thanks for the reply Nick. Do you have the functions like the oil level display and low coolant light light working through the Syvecs?

[nxi20]

I believe those functions are actually handled by other control modules but yes, they all work.

Nick, is your ecu taking it's speed signal from the ABS module?
