M1adam,
In our comparisons for 04 and 05 ecu which we had done on a dyno machine, it is proven that the 04 with light mods can easily see a value of 109-110 on links dyno machine...with the 05, 06 and 07, its somewhat much lower, averaging at 105-107, both this cars have very similar mods.. i do believe thats is one of the reasons why siemens lower the ignition is because of aftermath of the pinging, not only on the valves but also on the piston rings..i just need to advance a little more on the ignition side..where can it be done on the ems700, please explain..i don't really think the PDT2000 can do so much..
there were rumours of increasing the idling offset to -75 or different value to play around with the preset igntion timing..but its not convincing..i during those early days, me and a group of friends got corned already, having to pay to some dealers claiming they can advance the timing by increasing the idling, which of course led to higher fuel consumption and poorer braking performance due to the vacuum differences.
