211 ECU

[Boothy]

Does anyone know if a 211 ecu will run an exige S? I know that the stack units on both cars in question are the same but the 211 has variable TC and the exige in question does not have TC.
I also know the 211 only has one lambda sensor and the exige has two...
Other than that is there anything else that may cause a problem? I can't seem to get a definite answer other than stick it on and see what happens...
I realise I need the lotus injectors and possibly the upgraded fuel pump, I have been told that it will shut off the TC if it does not find a switch for it and that the lamda should not be an issue?
So does anyone know the answer to this other than stick it on and see what happens...

A 2-Eleven ECU will ONLY work in a 2-Eleven.

If you plug it in to any other Lotus it will not function.

[Boothy]

How do you know this? Lotus themselves have said they will fit it at Motorsport, but its a fair old trek and not cheap at all as they want to fit all the 260 options at the same time... So in theory it should go.

Andy,

I know it because I went up the mountain...

I had this very discussion with Lotus Sport in Hethel this year.

I think what Lotus Sport is offering to do is to sell you an ECU that will give you 260hp and variable TC. They can do that but it will not be a 2-Eleven ECU.

A 2-Eleven ECU will only work in a 2-Eleven but that does not mean you can't not have all or most of the features.

If you pulled an ECU out of a 2-Eleven and put it in your car (assuming your car is not a 2-Eleven) it would not work.

[Patricko]

Just to wrap this up.

If Lotus Sport told you they can sell you a solution for your car I am 100% sure it will work and do what they said it would. You do not need to worry that you will drive from Bolton to Hethel for no good reason. It will be fine.

The distinction I am making is that if you some how were able to buy an ECU that came out of a 2-Eleven I am 100% sure it would NOT work in anything but a 2-Eleven.

I hope I have unmuddled this for you

I have access to a 211 ecu, I spoke to Lotus and the solution they were offering was to fit that ECU into the car, not remap my own ecu.
What is the reason it will not work? the stack is the same and the systems it runs should all be the same?
The only real difference I am aware of is the single lambda sensor.

If Lotus told you they can make it work then it will work if they do it in Hethel.

You can not make it work.

Go get the ECU and plug it in if you think I am wrong.

The ECU knows what kind of car it is plugged into.

Not trying to be a jerk but what tips it off that it is not in a 211, is it the injectors or MAF? Is it the same motor?

Thanks,

Ken

[Boothy]

Exactly, its ok to say it knows but the question is how??? Its the same motor, same injectors, same stack etc so what tells it?
I can just get it and plug it in so thats probably worth a punt.

211 doesn't have any immobiliser for a start - that might confuse it.
Also you'd need to confirm the pin arrangement of the socket is the same - no reason why it should be different but again no reason why it should be the same.

[Boothy]

I'm not sure how the immobiliser works on the Lotus but guessing it could well be a problem.

Check the pins and plug her up. Let's see what happens.

[Patricko]

I am done.

I hope this experiment does not cost you too much dosh...

What kind of answer is that? I asked how you know and how the ecu knows what kind of car its fitted to? You can't just say something and not back it up with facts.

I think the problem is that you have asked and people with experience told you it won’t work and you don’t listen. You seem to want to find someone to tell you what you want to hear. There is not much more frustrating than trying to help someone and they don’t want to listen to you.

Try it and get back with everyone. Sometimes the best knowledge is failure and spending a lot of money doing so.

Good luck...I will go back to lurking.

Eh? At which point did I not listen? If somebody tells you something will not work do you just accept it or question why it won't?
Its fine to say something will not work but explain why it won't work, don't just say it won't.
All I did was question how the ecu knows what car it is on... can you explain to me what part of the car tells the ecu what it is?

It is not my job to give you an education. You asked for info. I gave it to you. You were not satisfied. I gave you more and you don't seem grateful.

I am not going to nor is it my responsibility to draw you a circuit diagram.

You seem to want the answer you want and you will not be happy until you get it.

Why don't you call Lotus Sport and ask them?

What an odd reply. If someone tells you something you just accept it do you? I have asked this question of an engineer who works for Lotus at Hethel after I asked here and he said it will work fine...
Back to the point in hand, I asked a question and the only actual reply was yours and you said it won't work, I asked you why and you said because the ecu knows what car it is on. At this point Ken Wright and myself asked how does it know what car it is on? yet you do not seem to either know or be able to tell us.
Its got nothing to do with not wanting to listen to your answer because its not what I want to hear I would just like to understand why it won't work, that is all.
