krede Posted November 20, 2006 Report Share Posted November 20, 2006 Hey everybody I need to fit a rpm sensor to my Murena 2.2L as im switching the carbs for TB's. Some sort of TDC sensor is fitted to the murena but Im not sure this can be used, in fitting electronic enginemanagement, thus I am looking into using 505 parts, as the engine of the murena is more or less a non turbo n9te. Can anybody tell me where the it is placed on the n9te?.. and perhaps up a picture of it? Quote Link to comment Share on other sites More sharing options...

That sensor is only for tester use (I have throwed those away) if u mean that one in under cluch cover (below). rpm is read from ingnition pulse in 505.

august Posted November 20, 2006 Report Share Posted November 20, 2006 welcome! I've only seen TDC sensors on early (85-86) 505 turbo's. It was located on a bracket that covers the flywheel and bolts to the bottom (back) of the block and the transmission. I'll have to look around for some pictures. I might actually have one lying around somewhere if you don't have any luck finding one. (aah! V-M you beat me to it! ) Quote Link to comment Share on other sites More sharing options...

V-M yes.. the TDC sensor on the murena is situated in the bellhousing/clutch cover. The one i need is for crank position. Quote Link to comment Share on other sites More sharing options...
Johnny Posted November 20, 2006 Report Share Posted November 20, 2006 What system are you going to fit? Quote Link to comment Share on other sites More sharing options...
krede Posted November 20, 2006 Author Report Share Posted November 20, 2006 What system are you going to fit? It's an Australian made system called wolf3d. I change mostly because the twin 40mm dellortos fitted now, are hard to live with in daily use...and too thirsty. Quote Link to comment Share on other sites More sharing options...
Johnny Posted November 21, 2006 Report Share Posted November 21, 2006 If your system can use a hallsensor, then the hallsensor in 505t's distributer would be ideal. I have used it when controlling ignition with megasquirt. Quote Link to comment Share on other sites More sharing options...

krede Posted November 21, 2006 Author Report Share Posted November 21, 2006 I was planning to discard the distributer all togeather and let the ECU control the ignition.. But it might be the easiest way to use a 505 distributer. I was considering Megasquirt aswell.. but in an attempt to limit the sources of possible trouble I chose a commersial product Quote Link to comment Share on other sites More sharing options...
Johnny Posted November 21, 2006 Report Share Posted November 21, 2006 The Megasquirt-ecu controls the ignition. The only thing the distributer does is distribute the spark to the right cylinder (besides giving the ecu an rpm-signal from the hallsensor). But you're thinking of using a multiple-coil system? And megasquirt is not hard to put together if you have basic soldering-skills. Quote Link to comment Share on other sites More sharing options...

I was thinking of using multiple coils, as it all came with the ECU when i bought it. But still the distributer could be left in place, if not for anything else then to get the hall signal.

Yeah, the first megasquirts were only fuel, but you can load an extra-code into them and then you can have spark too and a lot of other stuff, like launch-control, shiftlights, waterinjection-control, and lots of other stuff. You can read more here if you want to: http://megasquirt.sourceforge.net/extra/ I think that megasquirt-extra supports multiple coils too, but I'm not sure. I know that you already have bought another system, but info is never bad to spread (unless the info is bad ) Leaving the distributer in place for hall signal is probably the easiest way to do it anyway.

Peder Posted November 23, 2006 Report Share Posted November 23, 2006 But if you are gonna go with multiple coil you still need too keep the distributor(with the hallsensor for camsync)! unless you are gonna use a multitooth wheel!? //Peder Quote Link to comment Share on other sites More sharing options...
