:laugh: quality.
Glad i still had some Lego from the old days :D
Great thread this guys :agree:
Those renault sensors don't produce much output at crank speeds, lots of standalone struggles with them. One trick to test for this is to remove one bolt from the sensor and push the sensor down as close to the flywheel as you can before it scrapes. It makes about 20% more signal at 250rpm crank speed.
how fast does that beasty spin at matey?
it doesn't spin really fast. i have a replacement trim pot which probably doesn't do what it has to do. unfortunately the electronics dealer doesn't have it in stock so'll have to wait till new year :sad2:
also i have a peugeot vr sensor atm and it pushes out a lot more current then the Renault item. 3v vs 1v:laugh:
Using Scoff's sensor with my EDIS setup and closing the gap from 1.5mm to about 0.9mm ju ped my cranking voltage from 1.2v to 2.5v!
Nice Lego setup Tutuur! Whatever works...:D
Schwartz, great to hear your problems are sorted now! I'm still having issues but think it's Carb related now? I'll pull the carb off and take a look and go from there.
Lol, it was what i had at hand first! Now have a v2 with the peugeot crank sensor though. The sensor is strapped down with a zip tie and put some stabilisation lego bars to the triggerwheel fork :D
V2: (3volt with 1mm gap :p )

Finally got the tach input working!
Op-amp u7 was blown, going to fabricate a bracket for the peugeot vr sensor tomorrow and try to run the 9 on Monday :D
Pmt? :D
Pikey mod tuning;)
Ah, got it!
finally have it running :D
this is the Peugeot vr sensor with a bracket i made in a hurry (going to make a better one in time):

Sounds ace matey. Seems to rev up really well. Love to see the fuel and spark tables:D
Those Renault sensors are poxy.
needs a lot of tweeking! this are just maps i got from someone running a f4rt on Megasquirt. haven't got much time yet to do anything with it.
going away for a while too next week so you would have to be patient :cooter:
Either way sounds like it runs well looks like a really nice project.
thanks mate :)
how's your car doing?
Your doing a good job there mate great project
Yeah still idled well havnt driven it yet, been making it wider:D
Aha, almost forgot. The 16v track :)
