I have taken this from BillJ's website to adjust the basic boost pressure on my 96 9000 LPT with Speedparts ECU. I'm having a little bit of trouble in finding the boost reading.I have an aftermarket boost gauge fitted to take readings
Take the car for a test drive and with the engine at normal operating temperature, select third gear (manual or automatic) and accelerate at full throttle from below 1500 RPM (avoid the kickdown on models with automatic transmission). As the engine speed approaches 3000 RPM, press the brake while holding the accelerator, to achieve full load at 3000 RPM (pressing the brake pedal also causes Trionic to drop the boost pressure to base boost on non-LPT models). Note the pressure on the gauge.[/b]
I have taken onboard the above text and spoken advice from another source.
The way I read the above is that when pressing the brake pedal, the boost needle will drop to display base boost.
On the otherhand, I was told that when pressing the brake, boost will read maximum boost pressure.
Which should it be? I am somewhat slightly confused
