At best this unit will only stop you getting 7K Tacho error codes something you can probably acheive by just disconnecting the pully cables from the EXUP valve. If your EXUP valve is seized then no electrical gizmo is going to fix this for you, you'll need to address this through mechanical / manual means. You'll need to get the valve out of the collector box and soak it in parrafin / penetating fluid and try to work the seized components free over time. If the retaining bolts are seized then you'll need to drill them out or get a workshop to do this for you, replacing the bolts with stainless items is a good bet, check the FAQ for sizes. Maybe let us know where you are with the valve so we can better help ..............
