Ok, so here I stand, my micra has no injector, has no speed sensor.
And I want a tripcomputer in that car now !
At the junkyard, I got a tripcomputer from a Saab 9000, or five maybe...
Also got me a GM injectionsystem from a 1.3L engine complete with sensors.
The micra was customized and I supplied:
TPS, MAP, RPM and WAT besides that I let a injector laydown to simulate.
Tapped speed at the original micra speedometer. And fuel at the simulator injector.
Everything worked, I got values at the Saab computer and as a acc. it went up and in coasting got down.
The difference in total after a couple km was not that big, this was a mess.
So now I had orderd a flowsensor just as I planned in the begining.
the Zemco was a non-FI trip computer and included all it's own sensors including flow, speed, in,out temp, and a cruse control functon. the only thing it didnt have that the scangauge does is instanious mpg.
i've seen them on ebay b4. i just wish in my pre driving stupid days i hadent riped apart my dads
