which wire are you using? you can get the signal from two places for the tach, straight from the tach signal wire or from the crankshaft sensor wire. either way you need an o-scope to set up the sensors from scratch, or you have to know what the square-waveform is supposed to do.

two big issues with our car and piggyback units: the tach signal is difficult to read from the sensors either because the signal strength is low or because the signal is abnormal(not sure which at this point, my SMT unit arrived defective,) and the MAF sensor is a karmen vortex type that operates on frequency instead of voltage. well, that's two that relate to your question.

 

figured it out ok for some unknow reason even after i save my settings in the piggy as a 4 cyl it changes it to 6 next time i start my car...odd....when i change it to 4 rpms are read perfect so now i guess i will read my manual a bit more and scan some forums

isn't it so fun how everything always works so well in theory...the joys of working with cars

 

prob solved my stupidity lol

 

post up a DIY man! no one has done with the safc what you have done for themselves, only had others do it for them

 

well there is already all the info required in my other post where i begin by pleading for help but if enough people want i could make a diy i guess....yes or no
lol its kind of funny though i got it all set up but i cant tune until i get a wideband and right now until i moove im on a bit of a budget so no tuning yet dam

 

yeah, the software settings and some various screenshots would make it simpler to understand. the wiring diagrahm was A+ though.

 

Hello Face

I recently installed the Road Race Piggy back and zeitronix wideband on my 04 Ralliart. I am not able to data log my RPM or TPS through the software and I can't connect to my ECU through the Split second program. It attempts to connect through com port 6 but says "unable to connect to ECU."

Can anyone tell me the process of connecting and datalogging? Any help would be great.

Thanks

 

How are connecting straight serial or usb / serial cable ?
