As per the title really, just seen that they are now advertising the new MBE units, with knock control. Anyone yet to take the plunge?

Nothing on their website yet about some of the other stuff that the alternative Syvecs advertises (Traction control, switchable mapping for example). My understanding was that the new MBE has these capabilities?

I'm still running in my new rebuild but once i've done 3 or 4k I had planned on getting a bespoke map, but not sure if it'd be a waste of money and it's a case of "if a jobs worth doing" etc?

Idle air control is great on modern cars, but most people warm S6 cars up before driving off, to keep wear to a minimum,

add to that, it might not sound the same on overrun

I'm not sure anyone who knows what their doing leaves their speed 6 to idle away to temperature before driving off.

Yep, that includes most flat tappet (RV8) and rocker arm/finger valve gear aswell.

30hp up at the wheels? I find this most unlikely unless the car had big fuelling issues or retarded ign timing prior to the install obviously not having a pop at you RichTVR

Unless the car has issues, I doubt you'd see too much in the top end figures - it should be the mid range and drivability that improves.

The Syvecs sounds better to me though, this still seems a bit old-tech.

I would imagine most would only consider the new ECU as part of a complete upgrade package, like 4.5, or FFF, with Syvvecs or the new MBE.. I've got lot's of other things to spend 2k on before a ££££ engine upgrade/rebuild (fingers crossed)

The recent turmoil at TVR have resulted in many of these projects lying dormant and rather than let these projects fade into memory, MBE and "Powers Performance" in conjunction with John Ravenscroft have decided to blow the dust away and let TVR drivers experience some of the features that only that original TVR mentality would have produced.
The features that were near to production were:-
Enhanced Logging capability
Euro 5/6 emissions compliance including sequential port injection
Encompassing Drive by Wire
Wide band Fast Light Off Lambda Control
Variable CAM control
Knock Control
Throttle body Production variance compensation strategies
ESP/Traction Control
Automated Transmission
Knock Suppression Strategies
Intelligent cooling Fan Control
And………
LCD Dash/Display
Flatshift
No EPROM
Plug In existing harness

Obviously some of the above enhancements are not practical for retro fitment to existing supplied engines and the primary purpose of those enhancements were for emissions compliance. These features include drive by wire and variable CAM control. Other features lend themselves to retro fitment and have an immediate and direct benefit. These include….

Wide Band Lambda Control
Knock Control and Knock Suppression Strategies
ESP/Traction Control
Intelligent Cooling Fan Control
Sequential port injection
Multi pulse sequential port injection
The Engine Management System is capable of Dual Channel Drive by wire, we decided, however, to retain the original Throttle mechanism but utilise the Engine Management System’s features to enhance Idle Quality especially during the warm up phase.

I find these new ECU's interesting but I'd also like to see a before and after comparison, including dyno plots. 3 grand (incl. VAT) is a big chunk of money and in my mind is about a grand over what I was expecting it to cost.

It's hard to convey the benefits of such an upgrade to anyone who isn't knowledgeable about engine management systems so a before and after video of the system in operation would go a long way toward showing how it performs.

To be fair, I think it isn't far of the Syvecs' price, and seems to be doing pretty much the same...
