**UPDATED**

These tables are from the Lotus Esprit GT3. I've also got the code for the Esprit SE and for the later S4s. Each Esprit has quite a few differences. What I would like is other types of Esprit so that we can compare how Lotus has tweaked the ECUs though the production run of these engines.

(This page is obviously full of graphics therefore slow to load)

Remember that all of these parameters are fully adjustable with Tuner Cat and my definition file (TDF)! 

My TDF for the GT3 and S4s is now available but <very> expensive! However, I can make customisable versions to order, please Email me.
