BTW Zax, there is a dutch guy that has been remapping 4AGE ECU's for age's, but he hasnt disclosed any info since he made money remapping ECU's for ither guys. With some proper tuning software this might be an interesting thing to toy around with..
Imagine the benefits for relatively normally modded engines (cams, intake, exhaust), if you could get a proper map for it and run it using the factory ECU, with all the fancy correction factors still in place (possibly modded lightly as well)...
The trouble I suspect lies in making good mappings.

With my system there are no secrets about the mapping.
It is all displayed on the laptop screen for the user.

Maps can be altered by pointing and clicking with the laptop mouse.

Also it is possible to create a date/time stamped report from the ECU on all reprogrammed maps.
It can be printed out and shows before and after changes of any remapping. All the maps that can be reprogrammed will be listed in the report. This includes the rev limiter setting and TVIS setting.

Maps could be compared/exchanged between owners.

Also you can datalog test drives in the car and play back the journey on a viewer program. See http://www.jmross.freeserve.co.uk/page1.html

You could monitor how the fuelling has changed if you datalog 'before and after mapping' test drives.

This datalogging capability will be included with the ECU too. You even get a fuel economy readout on the laptop as you drive the car.
