That's a fantastic price, GLWS. Buyer would only need software from ESS. Do you have the white/gray-ish injectors? If so, the buyer could possibly get the 625 software from what I understand.
What were the track temps and how many laps per session were you doing to see a rise in oil temps? I haven't seen even a 1 degree increase in 3 track days (about 9 sessions of 10-16 laps per session).
