abandoning tfi project. maybe the whole project.

I changed the resistor to 120 ohms. no change. The engine still starts right up with spout out. Tuner studio shows good MAP good rpm . I ran trigger wizard to sync distributor and ecu . Shows variable spark advance as if the table is being calculated for the running engine parameters. I am using the ...

Matt, I will try resistor change tomorrow

i have seen several references to a 100ohm pullup instead of a 1k ohm. could this make a difference?

here is latest .msq

it has been a while, but I am trying this again. Using reassigned wled that I replaced with shielded cable and 12v pull up through 1k 1/4 watt resistor.
the car starts perfectly with the spout disconnected and has been timed at 10 degrees btdc. I used the advance table generator and up loaded it and ...

Thanks. I will go forward with this strategy and let you know if it works

also, is their a difference between the way microsquirt 2 and v3 handle this. I have a v3

Thanks for the response. I guess my question is, since the ecu is getting a reliable PIP from the TFI module, does it matter where the Spout comes from ? I.E. is the value automatically generated and sent out via IGN 1 as a 5v signal unless told otherwise ? If so, it seems I could use IGN 1 ( pin 12 ...

I am trying to finish a Microsquirt 3 install on a 1968 Cougar with a 302 4v. I am going to use a GM TBI. I have wired the car and initialized the cpu and checked sensors. CLT IAT MAP wbo2 tps (temporarily hooked up ). the sensors work ,I have actually been driving the car for 8 months with carb and ...
