Just bought a tuning box from ebay 60quid. Decided against remap - probably will be selling her soon. But tuning boxes can be sold on ebay. Aparently they are intercepting injector opening time and injection pressure. Want to try bench test to see how it works and what kind of voltage adjustements it does. And main thing - does it really use microchip to calculate or by switching dip switches changes preset values on different outputs.
