item 300191547449 as my links dont always work!

They can be a bit hit and miss from what i read, the professional kit is very expensive £1000's and these are DIY and can render the ECU useless with no way back.

Is it for a build or your daily car?

its for my daily car. 9000 saab LPT i want turning to FPT. an ECU be about the same price as the flasher kit but an aero ecu seems to be as rare as hens teeth.
