MaTTSuN Posted August 21, 2007 Share Posted August 21, 2007 this thing does not want to work everything looks like it works but the spark is not there i messed with the spark i every way to get it to work but all i can get is running on like 3 cylinders and now i cant even get that i dont know what to do i think im lost i pretty much have metros msq as a starting point the one in mobys sticky this msq worked the first time i started the car but then i loaded it again from a different computer and it got all messed up..... did i damage something when i did that? ever since then it wont run should i unhook my ms from my car and take it to my dads computer where i have the orginal msq that worked?.... i just want to drive the car ive always talked about haha the 350z killer ... i might unhook my ms from my car and take it to my dads tomorrow its just might be crazy enough to work.......... man this is fun still kinda pissed Quote Link to comment Share on other sites More sharing options...
mobythevan Posted August 21, 2007 Share Posted August 21, 2007 From your other post you said you have to run a +45 trigger angle addition to get it to do anything. That is not correct for an 83 style turbo dizzy (don't remember if that is what you are using). You should be able to run a trigger angle of ~60 with no addition. Otherwise it sounds like your dizzy/oil pump was timed wrong. Quote Link to comment Share on other sites More sharing options...
naviathan Posted August 21, 2007 Share Posted August 21, 2007 No need to unhook it if you have a laptop or computer close enough to connect to it while it's in the car (which you should if you're going to tune it). Just reload the firmware and .msq and try again. You could have corrupted the firmware somehow. It happens. Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted August 21, 2007 Author Share Posted August 21, 2007 im running the 81 cas and the msq that worked the first time is on the other side of town so ima pick up my dads computer and take it to my house hope that gets me started...

MaTTSuN Posted August 22, 2007 Author Share Posted August 22, 2007 ok i loaded the msq from my dads computer the one the made my car run and drive ok in the first place looks like something is messed up it ran allot better BUT it still feels like its running on 3 or 4 cylinders and is pretty ruff so i guess the next step is to hook up a hei to trigger the ignition. can i do that with a burnt VB921 coil driver? just switch the ignition to the fidle output ?

z-ya Posted August 22, 2007 Share Posted August 22, 2007 It will not run without a functional VB921 because it fires one coil which fires all plugs through the distributor. Did you check the basics like spark on all cylinders? Did you check your timing with a timing light? Does the timing match what is set in you timing map? Have you checked to see that all injectors are firing? With the engine running, pull the injector plugs one at a time. If the idle doesn't change, you know that either the injector or the spark plug is not firing for that cylinder. Quote Link to comment Share on other sites More sharing options...
Xander Posted August 22, 2007 Share Posted August 22, 2007 also check your firing order, 153624 Counterclockwise. I recently installed the plug leads in reversed order (clockwise) and the engine actually ran. Only the number 1 and 6 cylinder were timed correctly and the engine still ran!!! Not very well though Quote Link to comment Share on other sites More sharing options...
naviathan Posted August 22, 2007 Share Posted August 22, 2007 If you are getting spark your VB is fine. Make sure you are getting spark on all cylinders. I would also recommend pulling the fuel rail and testing the injectors to make sure they're all firing. Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted August 22, 2007 Author Share Posted August 22, 2007 ok so if the VB921 is damaged it would not do anything? like no spark at all? i guess that would be "good" since i can start looking else where like the injectors, it would be hard to get it to idle since its running so rough but im sure i could figure something out. ill be doing so more test tonite to see if i can track it down my wires are in the right order ill check my injectors check my crank timing and see what i got Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted August 22, 2007 Author Share Posted August 22, 2007 on the relay board it looks like i only used 2 injector ports on the - side on the wirering diagram it say to use 2 on each bank 2 for 1,2,3 and 2 for 4,5,6. can this be giving me trouble now and the injectors are not getting enough volts? im going to wire it up after work and see if it works better Quote Link to comment Share on other sites More sharing options...

MaTTSuN Posted August 22, 2007 Author Share Posted August 22, 2007 on the relay board there are 4 outputs the first 2 for 123 and the 2nd 2 for 456 i have one on the first 3 injectors hooked up ti the first slot i have the last 3 hooked up to the 3rd slot on the board what im thinking it hooking up the first 3 injectors on the first 2 slots and the last 3 injectors to the next two thats how its done on the diagram on the DIY site i forget who drew it, but im going to give it a shot ive messed with my timing all i can i think its sometihng with the injectors now could i have burnt out my injectors some how when i loaded the wrong code and ran it for a bit (had to get home) Quote Link to comment Share on other sites More sharing options...

Connect 1 to injectors 123, and 3 to injectors 456. Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted August 23, 2007 Author Share Posted August 23, 2007 yup thats how i have it ill be checking it out again soon hope i have good news later Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted August 23, 2007 Author Share Posted August 23, 2007 how can i test that ms cas on the pully is working right and picking up at the right signal? Quote Link to comment Share on other sites More sharing options...
z-ya Posted August 24, 2007 Share Posted August 24, 2007 how can i test that ms cas on the pully is working right and picking up at the right signal? When you crank the engine (disconnect the coil wire), do you see a stable RPM in Megatune? Quote Link to comment Share on other sites More sharing options...
badjuju Posted August 24, 2007 Share Posted August 24, 2007 im running the 81 cas My msns-e setup starting working right about the time i ditched my piece a sh*t 81 cas and just went with hall effect. for about $40 you can run hall effect, without a dizzy. three mags glued into the crank pulley, mount a sensor, and you're done. and the best part is, you can glue the mags in wherever you want, so you can know exactly how many * to set it to in ms!

MaTTSuN Posted August 25, 2007 Author Share Posted August 25, 2007 so what kind of glue and magnets and what kind of sensor do u use? ill be upgrading to a better system when i get the bugs out of this one i have a feeling my injectors are giving me the trouble since some of my spark plugs are clean and dry and just a couple others are black maybe i got 4 injectors out or 3 and one kinda out im cleaning them right now they all seam to flow when i push the needle in, im going to reinstall them and see what happens next post.....1 hour... ha Quote Link to comment Share on other sites More sharing options...
