ECM measures the pressures at the inlet and outlet side of DPF. the readings are calibrated in a way to detect if DPF is blocked above a certain percentage,and then the Regene mechanism is activated. Instead of regular 2~6 injections during normal driving , REGEN-mode has about 6~9 injections one Piston cycle,but added at the very late phase towards BDC and very short needle opening times(~500uS per Injection) compared to the regular driving(500uS~2.5mS per Injection). So I doubt if it has any big impact on Fuel consumption if the sum of needle open times during REGN mode increases only by about 1mS.

In high speeds your condenser is capable to cool down faster because of the wind and good ventilation. If you measure the temperature coming out from the vents, you will see a noticeable difference. Hopefully, your evaporators have been cleaned and filters changed. So they works better now. By the way what is the vehicle?

Rest assured , your A/c repair place has done a good job or the compressor is over runnging( not cutting off.

I have a Toyota Aqua NHP 10. It has inbuilt hard disk (Capacity Unknown) and i have copied some songs through CD's.I wanted to use a SD card to play music without copying it to the hard disk since i do not know how to delete tracks which are already copied to it. Is it safe to use an average SDHC card with an adapter to play music with the car setup? Will it make a problem to the existing settings of the setup and later locked? Appreciate if anyone can share the experience as i couldn't find a post relating to this. Many thanks!
