flames_187 Posted May 18, 2008 Share Posted May 18, 2008 Hi guys, i recently got a 77z with megasquirt already installed in it(MSII). I been trying to figure out why i am not getting spark for the past 3 weeks and in need of help. The car is completely stock with 240sx tps set at 7 psi until my wb and intercoolering piping gets here and i am running ms2 ver. 2.885. The car will crank but not fire up. I can smell gas and datalogging confirms i am getting fuel. I had sent the Ms board to DIY because my computer wouldnt reflash it correctly got it back and now the light flashes when cranking which it didnt before. (as i think it should to show tach signal). I also am getting the reset notifcation even before i crank (right when i turn ingition into ON position). And i also noticed my spark advance from my datalog to always stay on 40.5 (attached datalog). the coil is fine and the plugs look soaked in fuel when i take them out. config5_18_08.msq.zip datalog6.xls.zip Quote Link to comment Share on other sites More sharing options...
flames_187 Posted May 20, 2008 Author Share Posted May 20, 2008 i got it started last night. I turned down my pw @ -40 to 2.5 and 160 to .1 cleaned the spark plugs and matched the timing... I am still getting reset codes right when i turn MS on and the computer running but will deal with that once i get a good tune for the car.

Reset codes are only a problem if they happen when you don't turn the Megasquirt on. Because they happen with noisy signals, a lot of people talk about eliminating resets. But the reset you get when you switch the Megasquirt on the first time is the one that's supposed to happen. Quote Link to comment Share on other sites More sharing options...
