Teema tegemise idee tuli sellest, et tänu mitte eriti heale läbisaamisele võimeka EFI Technologi Euro4 juhtarvutiga kerkis üles tahtmine uurida alternatiive.
Bosch Motorspordi valikust jäi esialgu silma juhtarvuti MS3 Sport.
MS3 Sport eelisteks on:
kompaktsus 120 x 90 x 40 mm
kerge kaal 250 g
vastupidavs temperatuurile -40...+125 Celsiuse kraadi
Suhteliselt normaalne hind
Kõikvõimalikud funktsioonid - tõsi, mõned küll kopsaka lisatasu eest.
ECU MS 3 SportThe MS 3 Sport is the first Bosch enginemanagement system to be manufacturedwith full hybrid technology. Therefore it isvery small, lightly and robust againstvibrations. The MS 3 Sport is suitable forengines with up to 6 cylinders and has internal ignition output stages. Twosensor inputs are available for vibrationknock detection and knock control. Various engine parameters can bemeasured with different input channelsand transferred via CAN interface to anoptional data logger or dash display.
Application:*Engine layout up to 6 cylinders, 2 bank
*Control strategy alpha/n
*Lambda control dual
*Speed limiter
*Gear cut for sequential gear box
*Map switch (3 positions - each corresponds to different target lambda and spark maps)
*Fuel cut off
*Sequential fuel injection
*Asymmetric injection timing
*Asymmetric ignition timing
*Interface to Bosch Motorsport ABS M4 kit
*Support of 60-2 and 36-2 ignition trigger wheels
*Max. vibration Vibration Profile 3 (see Appendix or

Funktsionaalsuses ei ole põhjust kahelda, aga nagu elu on õpetanud, ei ole suurepärasest seadmest kasu, kui ei saa hakkama slle kasutamisega.
Seega - Kas keegi teab kedagi, kel on kokkupuuteid Boschi programmeeritavate juhtarvutite seadistamisega ja tarkvaraga Modas Sport ?
