After numerous attempts to work out how to change when the shift light comes on the drv meter... i finally worked out how to set what rpm you want it to come on at. For anyone who is interested or wanted to know. Turn ignition on, as the rpm lights go down hold the power button until it flashes the digital reading.... like 30 for 3000rpm. Once that happens hit the power button to increase it by 200rpm until the desired rpm, turn off the ignition and its set. It took a fair bit of trial and error but managed to get there. I couldnt find anything on the web on how to do it, and figured there might be someone that was in my position and wanted to know.
