I can provide a patch harness to connect the M150 into the OEM harness for an M150 running Vitaly's package if you require.

What was the package price of this solution? Was it plug and play? How much post installation tuning was necessary?

We took the trouble to have Vitaly hooked up whilst we were setting the car up ... and then spent an hour on the dyno making sure that we had the tune "correct".

Biggest issue to debug was that the Australian spec MY2009 car has elements of the USDM "sport" setup and we had problems with the ECU losing power when the car was cranked. Vitaly sorted that for us overnight.

The package price is NOT cheap, but I am tipping AUD30K+ into a full race engine and already have a Quaife QBE69G sequential gearbox so a proper competition ECU (enabled for paddle shift sequential in good time) makes sense to me.

If you seriously want the budget numbers, please PM me.

We changed the TPS and started the car. What was strange was that the engine was surging in RPM, then it would make a "Whoosh" sound and go back to idle. It did this over and over again. I shut the car off and restarted a moment later and it was fine. I re-did the learning procedure as indicated and it warmed up and idled properly.

Now I have to break some local laws and take the car out on the road to test it. It sucks that the nearest track is 3 hours away.

Just a thought in case anybody would have input. Could this issue possibly come from the VVEL controller?
