I have an opportunity to buy an original EFI ECU for my WVTA S160. I currently have an Emerald fitted.
Now I know most of you probably think I'd be mad - but it's all about restoring the full original lumpy idle and character so it runs as Lotus intended.....(albeit with the revised setup - see below). I think fitting Nitrons, Alloy Rad, braided hoses etc etc is all great, as it's pretty much essential on these cars as they age, but rightly or wrongly I have a view that the Sport 160 and other such factory specials should be, well, as they were intended to be, engine-wise certainly. Others will disagree I guess but we're all different..
Don't get me wrong - I may not go ahead and do this - that's why I'm on here asking questions!!
Not sure how many of you heard RobT's Nautilus blue S1 last Friday on the Hethel trip - basically it's a standard S1 with an S160 engine and ECU fitted, and it sounds, well, very different to mine. Mine has been smoothed out quite a lot by the map on the Emerald, whereas his has the 'proper' S160 character.
Anyway, the plot thickens a bit first - my car had the Lotus 'Sport 160 Driveability kit' fitted about 10 years ago by a previous owner, at great expense (part of a £2,300 invoice that I have...!), details here (original bulletin):
BULLETIN Model: 'Mk.1' Elise 160
TITLE: Availability of Elise Mk.1 Sport 160 upgrade kit.
REASON: To improve idle quality and low speed driveability.
The concept of the Mk.1 Elise Sport 160 model was to use a high performance engine specification in conjunction with sport suspension and was aimed at customers who enjoy 'track days' and similar usage. The engine characteristics require that high rpm and full use of the gearbox are employed to extract full performance. Idle quality and low speed running are compromised.
Continuous monitoring of customer feedback has resulted in the development of an upgrade kit to the WVTA Mk.1 Elise 160/Sport 160 (using the EFI controller) in order to improve idle quality and low speed driveability whilst retaining the original power output.
ACTION: Parts Required
Upgrade Kit, Sport 160 A111E0084S comprising:
Toothed Pulley, exhaust camshaft A111E0082S
Throttle Body, 52mm A117E6090S
ECM, exchange A111E0083S
(Parts may be ordered individually if required)
112° Exhaust Camshaft Pulley
The standard engine exhaust cam timing is 102° BTDC maximum opening point. The modified pulley allows the exhaust cam timing to be advanced by 10° to 112° BTDC MOP. Partly as a result of the reduced valve overlap, idle quality, low speed running and exhaust emissions are all improved, whilst the larger throttle body (increased from 48 to 52 mm) and revised calibration maintain full power output.
Back to my car - I have the 52mm throttle body, and I can only assume I have the revised exhaust camshaft pulley fitted too - though that could be a dangerous assumption, see below...
I have the guy checking the part number on the ECU - he believes it's the revised one as issued as part of the Driveability kit. So my thinking is, if it is the revised one, it should essentially plug and play - correct?
It comes with the harness adapter too - so in theory will plug straight into the car's harness (as I assume my Emerald does currently). My Emerald is quite old though, and I've also read that the harness plug/wiring on the S160 differs from a standard S1 - necessitating the original plug to be cut off when fitting an Emerald (perhaps). Not sure if this applies to mine, or even how to check...
If it is basically plug and play, is there any harm in trying it? I could always refit the Emerald I guess if it runs like a dog, because perhaps my car had some timing work done that I don't have a record of (I have invoices spanning the whole life of the car, there is no mention of verniers or anything...just the Emerald).
Would it be easy for me to fit, with my distinct lack of experience with these things? Does it need to 'learn', e.g. the idle?
Thoughts......? Appreciate many of you will be thinking why on earth would I swap the Emerald for the non-programmable S160 ECU which has a generic map on it.....but these things NEVER come up for sale, so it's kind of an opportunity - maybe...!
Remember - I know nothing about this stuff, so please go easy and put things in laymans terms...don't get too technical on me!

It's in its box, I've not taken it all out but it looks to be all there. The filters are not the best but are only sponge, also there is a tank tape repair of one of the windows.

We've had a two floor high spec industrial style building of about 5,000 sq feet built just off Nottingham Road in Derby. Over the last 30 years he has collected over 3,500 radios from ham radio to WW2 spy radios, right up to modern 3G mobile broadcast equipment given to the museum by EE.
We plan to open in the Autumn and as part of that we have entered a competition to help promote the museum. We (my dad is also a lotus owner) would really appreciate if people could vote for our museum in the competition on this link. http://museumsatnigh...e/#.Vyo6QtR4WrV
If your a Facebook person then we'll be giving more updates about the museum here https://www.facebook...museum/?fref=nf
