Guest mafiaz Posted August 17, 2008 Share Posted August 17, 2008 ok yesterday i had no fuel and spark with some tinkering i found out injectors were stuck my wiring was fine. Ran the test mode they went off like crazy @! (did the repeat test) had the plugs out too so i thought i blew a fuel line took me 3 mins to figure that one out lol so that un stuck them nicely for spark it was merely a loose wire So the car stumbles for like a second or less not running no idle but there are still some or i should say many issues. From here i figure its all software. Speaking of which in megatune my tps jumps around like crazy same as my MAP with key on ON postition. Is this normal. Cause i cant calibrate the TPS the numbers keep changing IM using a tps out of a 240sx w/ the TB i searched and verified with a digital multimeter that the outside pins are + - and the middle is the signal the colour are red white black so white is signal and left red + and - black i also switched the + - same thing in megatune the numbers bounce like from -2300 + 1900 % i also check that vref is getting 4.7 volts im stumped but im also very new to this so its no suprise i also searched as well also what would be a good fuel and spark map to get the car running decently im using metros fuel map and spark the only thing different is hes running a 74 distributor and HEI EDIT and 10spi of boost which probally makes a big difference im running the 280ZX turbo dizzy my setup is f54 .5 bored over 240sx TB narrow band o2 stock head stock t3 stock boost zxt injectors distributor fpr ms2 2.886 code with jumpered first settings new laptop.zip Quote Link to comment Share on other sites More sharing options...

Guest mafiaz Posted August 26, 2008 Share Posted August 26, 2008 no time for punctuation so in megatune under fuel setup -> General Settings / input smoothing factors i had them either to high or to low i put 50 for MAp and 50 for tps now they read perfect can anyone review my msq ? having a real hard time getting it to start and idle . Its fouling the plugs . How do you set timing in ms2? I think thats off also too much fuel Quote Link to comment Share on other sites More sharing options...
