The Lotus cars, unlike the Toyota, come with a EFI Technology Italy ECU. Depending on the model, these ECUs are basically modified versions of the Italian firms generic ECUs so that the end result is a proprietary product for Lotus. And the federalized versions are slightly different than the Euro market versions. Charlie is the expert with offering remapping of the OEM ECU.
If you are looking for an ECU that can be fully controlled by the end user I would suggest the stand-alone kit we offer. This product is made by EFI Technology USA (different company than the above mentioned, but the same name makes it confusing sometimes). This stand-alone system is designed to replace the OEM control unit. It will offer some features that the OEM system does not and supports some inputs that the OEM system does not, however it will also lack in some areas compared to the OEM system.
There are many stand-alone systems to choose from. Ours is unique in the sense that it is preconifgured for the Lotus and is packaged with a wiring harness for ease of install. There are different levels of these systems as well.
In short, if you want a good product for a set up that is within the realm of what most people are looking for (i.e. BWR kit and Katana) Charlie has a good solution.
If you are looking for a product that is something you want to tune yourself for your specific needs (i.e. custom parts, require internal boost control, wideband Lambda, custom engine specs, or race conditions that require specific adjustments for different tracks) then the EFI stand-alone is a good solution.
