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

no time for punctuation :P

 

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
