Purchased used GT86 and found out next day that previous owner had had vehicle remapped using Fensport Ecutek software. It was set on Map 2 and I have since switched it to Map 4 (non-super unleaded option).
1) I assume that having used half tank of standard unleaded petrol whilst in Map 2 setting will not have caused damage/ created issues?!
2) I have no wish to bear cost of super unleaded (sorry). Am I better of just keeping in Map 4, or go back to standard "factory setting" Map (and if the latter, how is this achieved?)
3) I presume previous owner will have voided 5 year Toyota warranty by remapping?
