Hi i have a 92tt auto-trans whit ash-spec ecu.. but now a want to put a mines ecu.

 

Is bad?? is good.

 

i used 95 unleaded fuel

 

thanks!

Id say bad to use 95 ron on a mines ecu.I have one fitted and keep to 98/99 ron fuel.The mines ecu is for japenese domestic market cars using there own fuel normally 100+ octane.I think you may get dett if used on 95 ron.

Agreed, sounds risky to me, especially with the hotter climate in Madrid.

ok, and if use 98 fuel octane?? in madrid have 95 and 98 octane fuel

98 octane fuel will be ok .I use 98 on my car with a mines ecu but only running standard 9 psi boost.No dett at that boost.Ive even used 95 when ive not been able to get 98/99 still no problems but i try to avoid using it if i can.
