The S1 model runs an earlier ecu system that isnt easily reconfigured....
We have a solution in a bespoke kit of components allowing the installation by us or for home builds...
Heres a comment from a recent S1 customer who installed one of our kits to upgrade his 143ps S1 Elise..
" Yesterday we made a 300 km test drive on the winding, very demanding roads in the Southern German Black Forest with the newly installed ECU upgrade.
The Elise is just great for these roads and now even better with your upgrade. I am very pleased with the result.
Slightly over 160 hp on a test Dyno Pack and a significant improvement in throttle response. Yes, good for frequent overtaking. Well done!!. "
