After a bit more exposure than this is currently getting in General Technical....
http://www.scoobynet.co.uk/bbs/thread.asp?threadid=100231
Anyone got any experience of swopping from a MY00 802 ecu to a MY99 801 ecu?
Quick answers would be appreciated.
Cheers

Come on 
take a look at this post .. I am also very interested to hear from people who have done this what gains they think they made, driveability, top end, smoothness, fuel consumption ...
.. even if you had an MY99 and then an MY00, can you quantify any differences. I'll post here when I have mine done tomorrow.
Ta,
Doofus.

Doofus is having one of the two I have for exchange in for sale section. The other is still available.
It is not going to change your car into a dragster, but there are obvious performance differences, and is good VFM whether you Tek 1, swap it or buy one from a breakers if you are not planning a remap. The fuelling and ignition maps are considerably better, there is a considerably fatter torque curve.

Just to say thanks to JOhn for swapping my 802 ECU for an 801 ECU yesterday. Pity neither of us had more time as I'd like to have had a wee blast in the silver monster sitting up your drive
Anyhow, in case anybody is wondering I had my 802 green ECU swapped for a 801 brown ECU from an MY99.
First of all let me say that I never thought I had a 'bad' MY00. It seemed to have a slight hesitation at around 2.7-2.9 K revs and a slight reluctance to rev past 5.5K through to redline .. but apart from that it seemed quick enough.
Now I have an 801 ECU installed. The hesitation from 2.7-2.9K has most definitely gone. I have not had much chance to test it but I would say it has also cured the 5.5K through to redline resistance. The motor seems to rev easier/cleaner and with less relutance.
Probably the biggest surprise is the engine's characteristics pootling around in traffic on/off boost. The turbo seems far more eager to come on song. Looking back subjectively, the 802 ECU seemed to take much longer to spool up, almost as through it was dragging itself up to full boost. The 801 ECU it seems as though boost is always there when you press the right pedal.
Flat out with WOT through the gears I would say that the 801 ECU has the legs on the 802. Don't expect a massive increase in BHP/torque but I would say the comparison here is correct.
Probably John with the maps for fuelling/ignition etc could explain these characteristics more scientifically.
Well worth it .. would recommend this for any MY00 owners out there .. now to start saving for the TEk3

I still have one available - I saved it from reprogramming. See for sale section.
The high octane ignition maps are the same. The low octane ignition map is retarded more on the MY00. The boost on part throttle is more on the MY99. The fuelling is less rich on the MY99.
