Value of "golden" salvage Engine
Discussion
Do you get a new loom with the S6 MBE Ecu as with the RV8 MBE conversion?
I'm one of those that understands the benefits of a better Ecu but have little interest in attempting home tuning so for me Mbe fits the bill.
I think people forget that good customers get more than the bill suggests.
I can't fault Powers for there aftersales customer care over all parts of my car let alone the Mbe.
As said above, if your confident with such tech then playing with your maps etc must be fun.

For the bottom end question.... Mine is still an untouched bottom end, with a few years now running over 440bhp.
Honestly, the current potential issue (so far) is the gearbox!
(It did decide to be aircooled on the way back from LM two years ago - it made it back but a new head gasket was required. Apart from that and some leaks from the aftermarket hoses, it's been perfect. )
I would however, like to have a revvy 4.2, better pistons (etc) when it's time to refresh the bottom end...

My 4.2 build will have the MBE upgrade once run in, as long as Dom doesn't mine installing and mapping it with the FFF2 head!
From someone "in the know' I heard the Syvecs and MBE are identical in features. MBE are an OEM maker of engine management and are s
te at marketing so you don't see them in mags etc much. I hear they do a lot of software for the US military, impressive CV indeed!
As said above, I too will have no want or need to map the car myself, i'll leave that to the experts.

I did read up on the MBE and it does seem to match the features of the SYVECS. I think if you had a powers rebuild done it's the way to go.
If you're not tied to powers though in theory you could go to any SYVECS dealer and get them to make any changes to the mapping / settings if you weren't keen on doing it yourself.
Both seem pretty excellent options relative to the OEM set up.
If this engine works properly I plan to take it to Litchfield's which people seem to think is pretty accurate.

Are you referring to my build Redspike? If so, my investment in the engine, forged 4.2 with FFF2 and simplex really deserves a far better management system than the current men setup. It was developed in 1996, remember what computes looked like back then..!!
Hi yes... So your choice is to a) run it in using base map and original ECU after having engine put back in car, then a full bespoke re-map on Rolling Road dyno I presume using the new MBE later on, or b) run it in on engine dyno using whatever ECU/base map and then a full bespoke re-map with the new MBE ecu also on the engine dyno..I only mention this as with all the work I thought it would be great to get actual engine flywheel figures for BHP/Torque rather than the traditional 'calculated' figures from a rolling road 'at the wheels' figure..
Running in on an engine dyno is, I imagine, about 15-20 hours ? Surely they have a 'program' from that that varies revs and simulates driving and changing gears, accelrating, retarding etc.
I plan on using a 4.3 chip in my standard ECU just to do the run in, which is not too taxing on the engine and no flat out runs.
I'll then take it to Powers and have the new MBE fitted, remapped and then run up on the dyne.
I don't know of anyone who would break the engine in on a bench dyno? To be honest, id prefer to do it on the road anyhow.

Interesting to read I was thinking would the new MBE handle the FFF head well and Powers be happy to do it. After my car comes back from upgrade I may have another option available I should sit between S spec and 4.3 with what I've done (I hope) so the possibility could be just add the FFF Head? Thinking it may save penny's over a rebuild and give me additional power. I'll then take it to Powers and have the new MBE fitted, remapped and then run up on the dyne.

If you look at some of the figures around swapping out the FF head for the FFF head with a full remap gets you 40-50 bhp on a 4.0S engine..... And it's £4.5k plus VAT from TVR Parts plus remap...
I'm doing lots of man maths at the moment before presenting the business case to she who must be obeyed :-)

Man maths... I'll play the what's that over there? Once wife turns around I'll be gone.
Understood about the rods mate that's where I was trying to be creative/lucky... my engine was rebuilt by previous owner about 20k miles ago. My car was once graham abbots (Speed 12 owner) and DJR 7 (orange Tuscan/Sag now R creating an S) Lawfield engineering did the build using parts supplied by Power (Dom verified) so engine currently is solid. I was hoping the fff head only addition was small money in comparison to a full rebuild (even a standard one) for the hp gain and prices quoted common sense tells me to just see how she is when she comes back and chill out 😎
Thanks for info guys

There's not really enough data out there, but I'm not entirely convinced that the FFF's make much more power without the SYVECS ECU. At a guess based on what data is out there the most effective thing you can do to a S6 is to get the cats out and put in a sequential ECU. FFF probably helps but I think it's much more marginal than the ECU.I'm doing lots of man maths at the moment before presenting the business case to she who must be obeyed :-)
I'll freely admit of the known FFF numbers, mine is the definite high spot. But I did do everything to it at the same time - exhaust, cats, airbox etc etc etc.
Personally I'd say if you are chasing bhp, LS or turbos would be better. But to increase the quality and power of a S6 engine, it's hard to beat.

My man maths went ary... my rebuild was done for G. Abbot via the factory recall Lawfield carried out work soon after.
Turns out my lump has some leaks and it burns through oil under load. Dom advised not to have the work done as it would only lead to greater probs so save money and just do the 6k service.
Looks like it was the push I finally needed so quick recalculation of 'Man maths' and I have gone for the 4.5Super Sports with AK-MBE etc etc
Figures to be added in future.
