Ben says you lose about 5bhp, but as the management is mapped specifically for that engine and turbo its a small loss compaired to the gain you get from that. the aum engine that i'll be using is 150bhp standard as is mapped to 230, so I'm not to worried about 5bhp :P

20vt conversion, sig pic coming soon!

My view is this, if you can get the factory managment set up then it would be my choice, yes it would take a bit more work but I think it is safer, let me put it to you like this, running without some sensors is or can be ok but you have lost the safety net, if you think about it, say that you have a fuel pressure problem and it runs lean or a coil pack delivers a weak spark that is all it could take to damage the engine yet at least with the factory set up you have the back up of it dropping into limp home mode and saving it before it is too late.

It is your conversion at the end of the day but given the choice oem is the better option if available.

Agree with Wayne.
If your engine blows up in a couple of years, will this company cover it?

well no, but if a knock sensor failed or if it blew up for any other reason it wouldnt be covered either

So anyway I've been looking into other options for engine management, am I right in thinking all i need to do is plug in the 1.8t ecu? I understand I need to get the imobilizer taken off, but what would happen with the clocks etc would I need those as well? And would the engine run OK without being remapped? I would get it done eventually but just wondering if it would run without it being done for a while

You need the loom and ecu.

Can I just plug the ecu straight in though or does it need something doing to it first?

Not 100% sure but I think it will need the immob removing.

if the engine blows, buy another!

qpeng ftw. and its doesnt really limit power, mine runs over 240bhp.

well no, but if a knock sensor failed or if it blew up for any other reason it wouldnt be covered either

it wont blow up, Ben is a legend!

if you run the 1.8t ecu, you will need the loom, clocks and i think you run your mk3 ecu with the 1.8t ecu..... arghhh i dunno! just go qpeng! :D

What kind of advice is if it blows up buy another.  :rolleyes:

And you only need to run the 1 ecu.
