Got it on mine too. It has made my car much more versatile.
The engine feels much smoother, especially at low revs and low speed. As a result it's an awful lot easier to drive the car in busy traffic / around town. Also, idle is much more stable, straight from cold. It starts off at 1000rpm and drops to roughly 700rpm as the engine warms up. On the open road the in-gear acceleration also feels a bit quicker and throttle response is even more instantaneous than it already was.
So for me, it has proved to be a clear improvement.

Has anyone actually had one of these fitted to a S6 car yet?
If so, what difference has it made and would you rate it as a useful frittering of spare cash

Have your MBE mapped correctly theres not an after market ecu out on the market that works better than MBE for Speed Six and AJP packagesIf so, what difference has it made and would you rate it as a useful frittering of spare cash

But the MBE ECU whilst perfectly adequate doesn't have (as far as I know) an idle control function. For the S6 this would be useful as the idle is all over the place depending on conditions and just seems too slow for the type of engine. If the MBE could control the idle speed at a steady, say 1150 for warm-up and then say 950 when hot, even with the AC on, it would make the idle much smoother and also keep the oil pressure up. I never like seeing single digit oil pressures when the engine is hot and the AC is on so now subconsciously hold the engine idle at 1000rpm to keep the oil pressure up.
MBE with custom map & idle control is the ideal solution vs. OTT for standard engines Omex option.

Further to the above is there an ECU out there that is a direct plug and play replacement for the standard MBE? By plug and play I mean an ECU that uses the same sensors and plug as the standard unit, but has more features (like idle control) and generally better and more modern/efficient engine control algorithms?
Do MBE not do an updated off the shelf version?

That's probably down to the standard mapping. I would be interested in how a properly mapped MBE compared with the OMEX as I suspect there would not be that much in it. Certainly stuff like fan temps is easily changed in the MBE - it's old news for Cerbs and I can't see why it would be any different on the S6.

Out of interest, does the Omex system have any improvement on fuel economy ?
Anything to help the amount of miles per smile with £2 a litre looming !
Assuming it improved the overall fuel consumption from an average of 20mpg to 25 mpg (a 25% improvement would be amazing so doubt it's actually possible), to offset the £2.5k+ all in, even at £2 per litre, you'd have to do at least 25k miles to break even on cost.Anything to help the amount of miles per smile with £2 a litre looming !

The S6 uses the same MBE ECU as in the Cerb for which it was originally designed. That's why it uses two throttle pots as opposed to one as it runs the engine as two banks of 3 cylinders in the same way it runs the AJP as two banks of 4.dvs_dave said:

- Does anyone with the OMEX kit fitted, actually know if MPG improved much ?
