Hi Guys

What guidance can anyone give in getting a supercharged v6 remapped with just induction and manifolds added?

Im learning that manifolds alone the ECU can learn but add the induction and you have problems. I’m trying to free up any restrictions end to end so keen to do the induction in addition to manifolds. Hence the question who has done such a thing and what did you do ref re-map.

Thanks in advance.

As discussed elsewhere, due to the encryption that Lotus now use, you might struggle to find anyone in the UK who can remap the OEM ECU. 

This is one of the reasons why are number of UK specialists are now offering aftermarket ECUs. Eg: http://elise-spares.com/lotus-electrical/lotus-ecu-and-upgrades?product_id=781

Open to aftermarket ECU as long as it’s tested and proven so thanks for sharing Jonny.

Anyone else got any experience they be open to share?

I do believe that KomoTec can still do this for you and through them their UK main supplier Hangar111. I'm sure they will be along shortly.

I'm very interested in new manifolds (KT or 2bular) and the carbon induction kit from KT for my Evora 410Sport as I bet that will give me at least 430bhp, more mid range torque and urgency and just about all the performance I will ever need, let alone be able to exploit with my poor driving skills.

Indeed the KT430 kit for the Exige ( https://komo-tec.com/Shop/en/Exige/MK3-Toyota-V6-350-380/Power-phases/Phase-EX430-Upgrade-75hp-65Nm-Exige-S-V6-350.html ) is essentially what you are asking for (headers, sports cat, carbon cai, new pulley (not on your list) and ECU tune.

The EX430 responds poorly to heat soak (as found with track work).

Apologies, I was using it as an example of the ECO re-work that was being requested.

I'm not getting dragged back into this option, that option, this works, this one doesn't as we don't seem to get anywhere.

I don’t think that KT can offer a bespoke remap, taylored for a specific car (which is what @alias23is after, I think). 

As I understand it, they have a ‘library’ of different maps that can be applied to certain combinations of components.

KT are also in Germany. That’s a long way for @alias23 to take his car!

Well worth the trip, bespoke mapping when on the rolling road is very available at Komo-tec, plus hit the Ring on the way home for a day "testing"

Good question. I have spent some time to sort this out for myself and posted some thoughts in the TVS1900 thread, since it was brought up there as a side topic.

KT - I called them - and as @Bravo73 says, they cannot offer a bespoke map. Either you buy their stuff (which for sure is one of the best), or you don't. Well, if you go there, you may probably be able to map the car with any hardware configuration.

Since I had the 2Bular manifold, race-cat + Lotus Motorsport silencer paired with a BOE cold air intake, I was off the map so to say. The only other options I found was BOE and InoKinetic in US, but that is not an option if you as me is located in Sweden. UK makes no difference, I suppose. I also found VR Tuned, but got very mixed reviews and an unclear answer about what their file could cope with.

From a technical perspective you have four options:

1. Go with the standard ECU - as I wrote in the thread above, you get roughly 450 Nm and 380+ hp

2. Re-flash standard ECU - The upside is that you sort out the ultra rich fueling, get more power, better response and optimize the VVT system. The downside is that it is not a bespoke tune if you don't live near those few tuning companies and you still lack temp/pressure feedback from after the supercharger. The cost start at about £1000

3. Piggy-back - The upside is that you can add more sensors for better control, get data-logging (closed loop wb lambda etc), still use OBD II and in some cases use loged data for improved calibration. And off course re-calibrate if you add other modifications.The downside is that you cannot control the VVT system, as far as I know you have to make the wire loom yourself and there is a risk that the standard ECU messes with the piggy-back. Many tuners/dyno-owners are sceptical to those systems. The price is attractive (£500), but it comes with more work and likely dyno-time £££.  So, this is probably the DiY option for the one who has done it before...

4. Standalone ECU - Plenty of upsides as long as you chose one that has all the CAN-communication sorted out to be PnP with your Evora/Exige. You get a more competent ECU, VVT-control, launch control, adjustable traction control, E85 functionality, closed loop wb-lambda control, temp/pressure feedback from after the supercharger so that you can optimize both safety and performance and finally you can re-calibrate for all future upgrades. The technical downside is that OBD II communication is a bit risky, even though it should work. At the bottom line it is the most expensive option. With mapping you start north of £2000. The PnP options I know are: ECU Master EMU Black, SCS Delta and Motec.

My conclusion is; if you are sure you don't want to go any further with your tuning ambitions, any of the four mentioned re-flash providers will for sure offer added happiness with reliability. If you may want to do more, these money are wasted unless you live nearby them, or buy into any of their kits. In this case I would go with stock ECU solution until I added more upgrades unless you see a value in a standalone ECU besides the pure power upgrade.

Really interesting info @#84 thank you.

Appreciate that KT maps are essentially designed to work with their specific packages, but wouldn’t they work equally well with similar hardware set up combinations from different suppliers? So, for example, I understand that there is an EX400 map available for the KT intake/exhaust manifold kit combination (ie EX370 plus EX390), but wouldn’t that same map be fine for a Lotus Cup R intake with 2bular manifolds?

@Mattmahope - I fully agree with your point and think with manifold and intake, as was the original topic, you take such a small step so that you are perfectly fine even though it is not exactly the same items. But, when you call them, present your setup and ask if any of the tunes you mention would be suitable to pair it with and the feedback you get is that they require a bespoke mapping onsite, then either it is bad idea to mix components, or they just don't want to do business that way.
