Guest donny206 Posted January 1, 2006 Can any see if there would be a problem with using a megasquirt on a my 206 turbo with the complex ecu etc it has already got? Would the fact it needs the origional ecu for most of the dash be a problem or would they intergrate well? Share this post Link to post Share on other sites
DrSeuss 0 Posted January 1, 2006 megasquirt will work as a "piggyback" ecu, just fine, either controlling a single set of injectors or an extra set of injectors. It will make the mapping slightly crude. But its perfectly possible. Share this post Link to post Share on other sites

TB_205GTI 1 Posted January 1, 2006 my 206 is multiplex yes Hmm.. I'm not sure if the COM200 relies on the Std. ECU then A mate is tinkering a bit with the original ECU. So far he had it remapped (it's now a 1860ccm, with std. 106 GTI cams). Peugeot Sport Denmark recon the ECU will enable limp-home-mode if it is fitted with wilder cams, but not too sure about it. The 106 GTI management can be remapped to use boost (with a new mapsensor aswell), but not sure about the 206.. Share this post Link to post Share on other sites
DrSeuss 0 Posted January 1, 2006 MegaSquirt is not a piggyback! Q. Is there a simpler version of MegaSquirt to only control extra injectors piggyback style? A. You can use the standard MegaSquirt to control extra injectors. You wouldn't need to hook up the coolant temperature sensor, if you didn't want to, you would just set all the temperature dependent values to 100% (warm-up enrichments, cold accel enrich., etc.). You don't need to hook up a TPS, you can just set all the accel enrichments to 0, and hook a resistor from the input pin (#22) to ground (otherwise the CPU will see a climbing value and go to 'flood clear mode'.) You don't need to hook up an oxygen sensor, just set the EGO step size to 0%. For the air temperature sensor, you would just hook a resistor across the pin (#20) where the sensor would normally connect. This resistor could have any value from the sensor curve (in the sensor section of the manual) to approximate whatever temperature you think appropriate, or you could use a potentiometer to tune the extra fuel with a single knob. Of course, you can retain any or all of the standard MegaSquirt sensors to gain additional control and tunability over the extra injectors. Taken from megasquirt.info I think donny has contacted the people most likely to map the 206 ecu in this country this is why he's investigating alternative methods of supplying the extra fuel. The method suggested by the megasquirt team is actually more crude then it needs to be. Share this post Link to post Share on other sites
Guest donny206 Posted January 2, 2006 The thing is would this be a goood option to use for the engine? Share this post Link to post Share on other sites
