hi all any 1 got any ideas on my problem i have everything working on the megasquirt fuel pump kicking in spark etc etc but i have no injector pulse i get 1 squirt when i turn the key off
any ideas :

 

One of a few things :-

1) Not getting a valid crank signal
2) VR pots not set up correctly in the Ecu
3) Cranking threshold not setup right in calibration
4) Broken ecu/wiring

 

does my tfi module count for anything on the pulsing side of things as ive ben trying to find what the wires actualy do but i can only find things for the ranger 2.9 so ive been going of that wiring,the wires i have are

blue/yellow pip out
blue/red spout in
black/green cranking start pwr
black run start pwr
green coil negative
blue/black ground

 

Well yes, if the crank sensor is being fed into the TFI module, and then the ECU is relying on the PIP signal to know when to fire the injectors. Have you configured the ECU for TFI inside Megatune?

 

yes the ecu is all mapped and set up i got a map from one of the skogenracing lads

 

Does it say "cranking" in megatune when you crank the engine?

 

ummm not sure were on the megatune does it say that?

 

Bottom right

 

ok ill go have a look and ill be back
i do reakon i have my tfi wiring wrong but i cant seem to find the right diagrams

 

at the bottom right is my flood clear its not that is it

 

No, but is flood clear lit up? If so then it means you've got a problem with the TPS, or you haven't calibrated it! Flood clear mode disables the injectors from firing!

 

ah i c i think i have wired it up wrong when i crank the engine over the flood light does come on untill i put my foot to the floor then it goes off but comes back on when i lift my foot off the pedal

 

Yeah sounds like you have your TPS wired up backwards..

Once you've sorted that, go and re-calibrate the TPS in MT and then set your flood clear value to be maybe 20 or so below the max TPS value (at full throttle).. (remember what the high number is when calibrating).

 

ok ill go try that now
ill let u know what happens

 

we have pulsing now just see if she starts

 

nearly started think i need to adjust my timing on the dizzy but my battery dead lol

 

yep started at 1.45 does'nt sound bad at all either just need to do a few tweaks with the timing thx for all your help
you going santa pod this weekend if ya are i might see ya down there and ill buy u a beer or 2 lol
