Hi Guys, Right what im wondering is can an SPS3 (i think, the type which allows tweaking of boost and timing plus immobiliser), be used on both 8P and 8L cars? Using the unit on an 8P works fine, although cant acuire the current settings in the ECU, but appears to send new settings to the ECU, but on the 8L it provides a "ECU timeout" error, cant quite remember the wording but basically saying it hasnt seen the correct response from the ECU in time. So is there two different versions of the SPS3, one for 8L and one for 8P era cars with the later canbus comms? We asked a Revo programmer at the GTI show and he said it would work on both cars?? If anyone can shed some light on this for me it would be greatly appreciated...... Craig.
