Hi,

Just wondered if anyone has any mapping tips on improving the spool-up of turbos.

Richen mixture, increase advance off boost, retard ignition.

Any pointers would be helpfull

Cheers

Richening mixture on an otherwise standard car is unlikely to help, as most are already running a touch over-rich to start with, and in any case you'd need to remap the ECU or use an aftermarket fuel computer to do it. Similarly, the timing is under ECU control and can't easily be changed without something like EcuTek.

The most effective ways to improve turbo spool on a standard car are to change the exhaust system for a freer flowing, preferably decatted one, and to replace the factory boost control solenoid with something like a Dawes manual boost controller.

I have a fully prgrammable ECU

...In which case it would be impossible to comment without knowing exactly what your base map is.

Best option in this case would be to contact a professional mapper.
