Hi!
I´m running a speeduino V0.4.4 with Arduino Mega 2560 on a Mercedes 190E W201 2.3 8v.
I have two problems:
1-I haven´t got injector signal when I enable test mode,but Ignition works perfect.
2- My ecu doesn´t recognize rpm signal from crank (36-1 trigger wheel and Ford Zetec VR sensor) but I have signal in my osciloscope (1.2v avergae and good signal).
If I put Basic distributor and conect the tacho signal from the car to the speeduino´s cam imput ,(and program on tuner studio) i have rmp signal (hall 0-10v on osciloscope,hall 0-5v on speeduino with the VR conditioner).
Anyone knows where could be the problem? I tried different ecus and mega,and I have the same on all.
Thanks a lot,and excuse my bad english.
