Exhaust Light Under Load.

[SKiTLz]

I just recently bought a new R32 GTS-T with some mods already done to it. I've noticed over the past week if Im driving it hard around 5-6000RPM the exhaust light in the cluster comes on. The second I back off the gas it goes off. (Im Assuming its Exhaust light. Thats what it looks like).

Im running a PowerFC with GTR Injectors, HKS 2535..

Does anyone know where I'd start in diagnosing this? Could it be caused by Fuel? I still have a stock Fuel pump so Im thinking it might be running outta fuel once I hit the high RPM. I dont know if thats even plausable Im just shooting out ideas.

Cheers fellas.

Well the PFC was actually installed in Canada and tuned here. But perhaps it is a bad tune? I just wanted to pin point it before I took it too a shop and spent thousands on re-tuning.

Doesnt it just mean that your cat converter is shagged?

pfc also uses the flashing light the exhaust looking one as also a engine check light. best get it checked out!

Look at Paulr33's PFC FAQ http://www.skylinesaustralia.com/forums/in...showtopic=64201

The PFC uses the check engine light as a warning, but it could be several things depending on how often it flashes.
