    1) Adapted IHI turbocharger on cast iron exhaust manifold.

    2) Adapted Mitsubishi Pajero 2.8 Disel intercooler with automatic cotrolled water spray (prototype module controls electric water pump depending on air temperature (on above 55ºC / off bellow 50ºC), RPM (above 3500 rpm), intake pressure (above 110 KPa). It sprays 4 seconds and stops for 2 seconds.

    9) 2 OEM radiator fans with 2 speeds. They are controlled by VIPEC 88 by the ECT and A/C presostat info.

    10) 3 level A/C pressostat:

    Low pressure setting enables a/c clutch to engage deppending on dash button request and Vipec output. It also enable radiator fan to run at low speed.

    Medium pressure enables fans at high speed.

    High pressure switch at pressostat shuts down the a/c clutch to prevent damage in case of overpressure

    Looking inside the menu ​​run time values - Fuel trims -

    Air con Fuel trim (ms) - 0.00 (this parameter does not obey the command with the air conditioner running.

    Eng Fan trim (ms)-o, o (varies between -2ms to +2 ms (when the fan is running) - Engine Temp 99 degrees

    Drive Fuel Trim (ms) -0.00 (varies between -2ms to +2 ms all the time that the engine works)

    Looking inside the run time values menu - Digital - DI2 - Air con request - ACTIVE.

    Looking inside the run time values menu - Auxiliary - 10 Aux Air-con clutch - ON.

    But Idle load Trins - Air Con Trim does not work.

    Was that a defect or problem the ECU firmware.

    My car runs at idle with the a / f 14.7:1 perfect.

    When you turn on the air conditioning the mixture goes to 17:1 and this time the adjustment of Trim Air con has to make this correction. However, this setting does not work can range from -2.00 ms to +2.00 ms, the A / F does not change.

    But if I do the same thing in Eng Fan trim function and the engine fan is turned on the A / F change at the same time for more (0ms to 2.00ms +) A / F goes to 12:1 or less (for 0.00ms. - 2:00 ms) A / F goes to 17:1.
