randy 77zt Posted May 17, 2005 Share Posted May 17, 2005 has anybody fired the zxt ignitor transistor with a megasquirt?the little yellow wire at the ignitor ?never had a problem with oem ignition. Quote Link to comment Share on other sites More sharing options...
Tony D Posted May 18, 2005 Share Posted May 18, 2005 Not with straight MSS, Randy---there is no dwell control. It may interface with later ignitors that seem to have more wires going to them, so maybe they do more than simply gate the transistor. MSS-E may be able to do it with its features. I am also not sure of the gate. Rise or fall to trigger the transistor. The signal from the MSS is VERY different from what I understand the stock ECU gives. On an O-Scope, the MSS gives: _________-__________-_________-_________-__________ I believe the stock ECU gives the opposite, ----------------------------------_ Shouldn't be hard to transform, but as we all know, I am not an electrical guy!

randy 77zt Posted May 18, 2005 Author Share Posted May 18, 2005 thanks tony-i get the waveform stuff.i took 2 years of electronics in college.but that was in early 80's before windows.so i suck with computors becuase i dont know much about software.so now i am trying to figure out the megatune initial settings with the ms notepad.i dont know notepad.i am going to run mss&e.at least that is what the pre-assembled ms is supposed to be loaded with.i might try hooking the little yellow wire to the ms just to see what it will do.i figure if i am going to trigger a msd it might work on the yellow wire.i am going to have to get my girlfriend to help me with the notepad though-i am getting pissed.my motor is on a stand that i can run the engine on out of the car.if i put moby's tune in it it should run-i got his file.but i want the engine to run before it goes in the car.

Tony D Posted May 21, 2005 Share Posted May 21, 2005 they have me going up north whenever I get back from Venezuela. I have to see a customer in Sac'to, and maybe over in Tahoe. So while I drive through, I can stop by. I always stop off in Modesto anyway to molest the idiots who formerly employed me (Atlas Copco / Summit Industrial). Nothing like stopping by with a smile on your face to let them know they lost another customer. "Professional Courtesy", doncha know!

randy 77zt Posted May 23, 2005 Author Share Posted May 23, 2005 give me an email when you are coming by.i live 1/2 mile off of 99.engine is not in car yet.have to update the car now.engine is ready.i got the notepad stuff fixed so i can look at the megatune for mss&e.mss&e should run it Quote Link to comment Share on other sites More sharing options...
smokingwheels Posted May 25, 2005 Share Posted May 25, 2005 try feed the signal thru a npn transistor this will invert the singnal 10k to the base 2k2 as the collector load this may correct a slight timing problem eg to do with the leading edge Quote Link to comment Share on other sites More sharing options...
