I actually did some research on this for a small personal project that I'm working on.
The stock Exige S240 IAT/MAP hybrid sensor is BOSCH 0 261 230 042 (2.5Bar), and according to BOSCH spec sheet, it mates to BOSCH 1 928 403 736 connector/pigtail.

You can get it from
Home » Shop » Connectors / Harnesses » Bosch » 4-way sealed Plug Bosch BSK Connector Pigtail for Bosch MAP Sensor
They also carry connector only or in kit form, as well as pins.

Thanks for the info on that. I went ahead and ordered both, let the swap begin!

Well now hold on, are you putting this on a 2006 Normally Aspirated Exige? If so, do you have the actual harness that goes into the ECU?

When I used the FastWorks method of integrating an IAT on a 2006 Exige, I had to add a pin to the main ECU harness at the ECU. Wasn't a big deal, but there was no preexisting harness on the car.

That bit I'm going to wire in. Luckily this isn'y my first rodeo with customizing a harness (try going LHD with a RHD harness). I think now I just need to source an extra pin for the ECU, hopefully that won't be too hard to find.

I don't know what the specific type of pins/headers Lotus ECU uses, but looks like Radium Auto has them for sale.

Hello Guys,

I just installed a Supercharger on my car as well. Its a 2005 Lotus Exige. I also wish to install a IAT sensor.
So basically all i need is the sensor from Bosch that goes into the Intercooler and those 2

I dont really understand much about these electronic parts of the car... I would greatly appreciate all the Help I Can get.

Kind Regards,

Soccs

I'm interested too, right now my NA/supercharged Exige is not taking account of the iat output and this is not ideal in my opinion.
The questions are: once the sensor is added to the ecu, that signal will be processed/read? Ecu remap is needed? Iat retarding will be enabled? What happens to the ECU once it starts reading 150F IAT?


Thanks

Anyone?
