Hello From Brunei

Gday fellas,

I'm an Aussie from Melbourne living in Brunei. Firstly thanks for having me. I'm very green to thr realm of hands on tuning but am quite familiar with mechanical work. I'm running a Link G4X WRX11 PnP Ecu.

I've just finished rebuilding my 2019 Subaru WRX STI as it had an unfortunate ringland failure at just 11,629miles since ownership new from the dealership in 2020. Long story short, new engine turbo etc and will have a build thread.

I will definitely need advise and guidance along the way and the topics covered has been helpful to get my car running.

Welcome! I'm quite familiar with the car and ECU, and there are plenty of other great folks here too. You're in the right place!

Looking at the engine bay, when on the dyno I suggest watching that compressor inlet coupler to see if it has signs of deflection when you run high boost. I'd also try a run with the entire intake assembly off the compressor housing to see if there's a significant change. I'm guessing that's a G35 or GTX35 and I've seen the HKS mushrooms be a significant restriction at that power level.

Are you running a jumper harness from early V11 to later V11 ECU wiring or is that just a North American thing?

Gday Mike

The car is running the airfilter temporarily as a precautions on the dusty/sand roads during the break in period until I get my turboguard fitted. You're very close, the vehicle is running a G30-770 and a closed deck from IAG and custom set of heads from 🇦🇺 of which have been ported and polished with 272 cams.

Pardon my ignorance as quite new to the standalone realm so I'm not sure what your reference to the jumper harness is. The G4X plugs directly into my factory harness and replaces the stock ECU.
