In a Jumpy HDI-110 of the year 2003 I have done some tests with the goal of increasing performance and decreasing consumption, I have physically modified the temperature sensors IAT and CTS. ECU is Bosch EDC15C,
The IAT sensor improves performance when set between 35 and 40ºC. This sensor does not imply the user to make manual changes according to the vehicle's condition, so for that one there is no need to modify the firmware.
The CTS sensor was also manually varied according to the engine condition, there is a large increase in power if the CTS indicates almost 80°C when the engine is actually around 60°C. Sure that it is due to the ECU decreasing the pilot injection.
In the maps it can be seen that the pilot injection varies drastically when the CTS is greater than 60ºC, so I should probably decrease the values in the tables of "Pilot-SOI correction f (TWater)" and "Correction Pilot-IQ f ( TWater) ".
I have also experienced that the engine runs faster, then should reduce the tables "Driver Wish Economy" and "Driver Wish Sport", for example 25%.
Correction Pilot I.Q.
Correction Pilot S.O.I.
When exporting the file WinOls shows the message "Not all checksums blocks / patches / sync-blocks could be corrected". However I think that the Checksum of the new binary file is correct, isn't it ?
This firmware modification is going to be my first one, all comments are welcome,
