Hi,
I am running MS-II V3 and 2.88 firmware on my turboed 87 325i for quite some time.I am using stock VR sensor on a 60-2 wheel and BOSCH 124 ign module fo fire the coil (JS10 to IGN).I just did engine rebuild and after the installation it fired up right away.Next day I tried to start the engine and nothing happened.The RPM signal is there,the injectors are firing,the injector pulse diode flashes and everything on the megatune seems normal,but there is no spark output.I have connected a LED with resistor to the IGN and ground and it doesnt flash.I have rerflashed the MS with the newest firmware,but everything is the same.
The only reason I can think of(if it can be any problem) is that while I was testing the new radiator fan the car was left with the ignition on for more than 20 minutes.
Thank you in advance for your help.
MS-II V3 no ignition output

Re: MS-II V3 no ignition output
If you have the spark output setting backwards (going low when it should be high, or vice versa), that can fry your ignition module.
Re: MS-II V3 no ignition output
Matt.thank you very much for your answer.I was really hoping it can be the ignition module and I installed 2 others for testing and the result is the same.The car was starting one day and next day it just didnt start,I didnt touch anything in the meantime.As there is no pulse from the daughterboard I was thinking can it be fried and all other functions are working just fine?
