ma ne ta shema, nego kompletna sema di se vidi kak je rijesen ulaz za TPS za ms.

i nemoj koristiti irf44z, nego irf640, puno otporniji tranzistor.

Nažalost nema, pokušao sam izgooglati, ali ne nalazim nigdje shemu MS-a.
Ima samo pinout i layout elemenata na pločici, ali sheme nema. :-(

Izguuglao sam sve živo i mrtvo, ali nema šanse naći shemu MS-a, kao što rekoh, samo pinout, ali kud ti pinovi dalje vode, nisam našao. :-(

Evo, riješih problem "hardverski" :-)
Nabavio drugi TPS koji se vrti u drugu stranu, malo tokarenja i eto ga.

Mogu probat, zašto ne, još bolje riješenje.
Mislim da tih 10 Mohm-a ne u praksi bi smjeli imati nikakav utjecaj na signal.
Hvala !!!

Kad sam recimo probao spojiti voltmetar na signalni izlaz da vidim koliki je napon, motor mi se počeo "buniti".:-)

ovo je jako cudno. Voltmetri isto obicno imaju poprailican ulazni otpor.

Ma to je sranje kad ne možeš nigdje naći sheme ni za ECU, a ni za Megasquirt pa da se može vidjeti o čemu se radi :-(
Negdje sam naletio na temu o share-anju signala između tvorničkog ECU-a i Megasquirta, ali sad se ne mogu sjetiti gdje je to bilo,....
