I'm doing a full LCR ecu and loom conversion on an Ibiza in the next month or so. Full wideband and EGT with VVT too. Will prob be a pain to do though. We shall see.
If the AEM has been stood then check the filter and nozzle. These gunk up.
It will be a pain Alex, pretty sure of that
Robbie, an Exige will provide you with a lot of fun out on track, remember. The Elise was my main opponent on track, I had the power but just couldn't stick with them in the bends, depends what you want I think. Straight line brute force, and goodish in corners, keep the Cupra. If you want to develop your track driving and become more aggressive with power quicker out the corners a N/A track ready car is for you. My opinion anyway, not sure what others would say...
