octane booster or remap?

[steve_walsh]

wondering if anyone has any opinions on which is best? im not to sure as this is the first scooby i have owned. the engine is away getting fully rebuilt and i dont fancy another detonation.

Be on the safe side and get it remaped

[dougster]

Need more information on the build?

If it's standard then standard ECU will suffice.

[steve_walsh]

as far as i know its api engines that r doing the rebuild and im getting strenghtened con rods, pistons for an 99sti, lightened flywheel, racing bearings,uprated crank and ported head. my cars a 93 import wrx.

Get an air/fuel ratio meter fitted and a knocklink too and use octane booster, till you gt it mapped, or if you find it's fuelling fine and not detting, you may get away without a remap.....it is possible.

[steve_walsh]

i am planning on getting all the gauges,knocklink and apexi ecu but im running low on cash as ive just bought the car and the rebuild + all labour is costing me just over £8000. where is the best place to get the octane booster and what price? i think ill run the engine in with the booster and get a remap once simon at japerformance thinks its ready for it.

defo remap

[steven_williams]

Speak to APi as they are doing the rebuild.

It will need to get mapped anyway to get the fueling etc right and the other perameters i think.
