i got everything hooked up, put a msq on the ecu

the water temp reads

the air temp reads

TPS reads

there is no RPM

and no fuel

i have metros msq because his setup was close to mine

my set-up is

 

stock 81 zx turbo engine

240sx throttle body

stock injectors

stock turbo

modified J pipe to fit sx TB

i have it all wired up through the relay board

i used the write up off the DIY page

 

 

when i turn my key on the relays on the board click fuel pump prime's and thats about it

no lights on the ECU go on

what is normal when u turn your key on? are lights supose to flash?

The fuel pump should go back on once you start cranking and you get a spark signal I think. I do not believe there are any LED's lit until the car is running. Then you should have one flashing with spark, and one indicating Warmup Enrichment.

when you first power the msq all 3 led will flash very slightly 1 time. the fuel pump will also pump momentarilly until psi is reached.

then when you crank the car and get a tach or rpm signal then the pump will kick back on and off again as needed.

if you have no tach or rpm signal while cranking than check the cranking rpm settings on megatune. set it to like 250 rpm.

also check your ignition setup choices in megatune.

if that does not work then check all your wireing from the coil and dizzy to the msq.

good luck. peace

I am not sure about the 81 but if it's an 82-83 dist..... There are some jumpers you need to move around on MS-II and add the resistor in the dist wiring. It's detailed on the DIYAutotune page. Did you wire it like they said?

i got some good new and i got some bad new well its all good news to me

i got spark now and she started

but she runs like crap poppin and crackin

but i know why it pops and cracks

first off the reason i didnt have spark is because the resistor on the 12v switch power to the rpm signal was to great. I bought a value pack of resistors and i didnt relize that they are not all the same, so i figured out the right one to put in and she fired up

 

the reason its poppin and crackin is i took my crank pully off and reclocked my cas wheel one bolt hole advanced because thats what TONYD did in his 81 build up but i dont think i need to do that since it ran like crap with that done

ill be puting it back sometime this weekend or maybe monday after work

shouldnt be more than a 15 min fix

 

im so excited that i have the megasquirt running and everything seams to work or at least it all should once i fix my mistake

i took my rab out so the test drive will be a little longer but this is the week it runs and this will be the month i have it on the road SO EXCITED

THANKS HYBRIDZERS HAHA
