Great info aletes!
It looks like only a couple EFI units have OBD-II via K-Line, so that might imply we get something like the EURO-12 or MT-501.
Can someone take a picture of the Fed Elise ECU? I'm just curious to know if it looks anything like these regarding connectors and shape.
Pictures of part numbers, labels, connectors, all good for bonus points!
Days later ... Lotus is most likely using the MT-501 in the Federal Lotus Elise. Although I don't have confirmation from EFI Technology that the MT-501 is used in the Toyota powered Elise, I do know that Lotus used the MT-501 in the Esprit. Given that the initial development time for the 111R ECU was only two weeks, it would stand to reason that Lotus used off the shelf equipment. Until, I or someone else contacts one of the EFI Technology distributors this is just speculation.
I could only find the MT-501 documentation in one place:

· Knock control acting on individual cylinders and boost control.
· Individual cylinder correction for injection and ignition.
· Sealed aluminium enclosure with a 88-pin connector and surface mounted devices.
· Full filtering of all inputs and outputs for maximum EMI protection. All components are extended
temperature range.
· Programmable via CAN bus and full on-line mapping.
· Communication via a CAN line, 1 serial and 1 K-line.

· Closed loop lambda control for environmental control.
· Closed loop self-learning boost pressure control.
· Closed loop idle speed control.
· 2 complete calibration maps runtime selectable by the driver.
· Speed-Density (manifold pressure versus RPM) or Alpha-N (throttle position versus RPM) mapping for
aspirated or turbo charged engines.
· Electromagnetic or Hall effect speed sensor triggered by EFI Technology standard configuration.
Electromagnetic or Hall effect synchronisation sensor on camshaft.
· Full throttle gearshift.
· Programmable outputs for variable camshaft timing, variable inlet length etc.
· Launch and traction control.
· All sensor inputs are user configurable.
Here is a picture of the stock ECU ... It is kind of fuzzy.
