I have just purchased a wrx turbo(2005) 330 BHP with an aftermarket ecu simtec. My concern is that here in Malta our fuel octane is too low 87 and we don't have the 95 octane. My question is does simtec ecu offers learning mode to change timing settings according to our low octane. Would you recommend re tune ecu with low octane to avoid issues?
Thanks all for your help
