ECU First?
Hi guys,
I was thinkin about buying an aftermarket ecu as my first performance mod and wanted to know if this was a good idea... I planned on getting the ecu first because my car is imported so the engine is jap spec which runs on 102 octane while in Australia the highest offered at the pumps is 98. SO i didnt want the car to run rich for long and thought that an aftermarket ecu could tune the car to run on 98 octane instead plus i will be doing further mods to the car in future as well but wanted a place to start...tell me what u think

An aftermarket ECU isn't necessarily a good first mod. The stock ECU can cope with the first batch of mods quite easily as long as the fuel pump is upgraded and the boost is kept down (wastegate porting required). The big advantage the stock ECU has is that the AFM allows airflow mods to be catered for (up to a point), whereas MAP-based aftermarket ECU's must be retuned any time a mod significantly changes VE.

octane is not octane...here in germany we also have 102....on base they have the US octane equivalent next to the german octane number...
98 is 95US octane and 95 is US 91 octane and 91 is US 89 Octane
so my guess is that 102 is like a 97-99 US Octane
