dcarrter21 Posted February 25, 2011 Share Posted February 25, 2011 basicly you dont need to do it, if your worried about fueling either get an afr gauge or get the car on a dyno to make sure its running ok on 1.2bar! Link to comment Share on other sites More sharing options...

But as we now talk about it, what do the AFR shows usually at idle speed? Link to comment Share on other sites More sharing options...
Wez Posted February 25, 2011 Share Posted February 25, 2011 i have a afr gauge on the car.. But as we now talk about it, what do the AFR shows usually at idle speed? It will bounce around a bit while it tries to correct the fueling but it should be aiming for around 14.7afr at idle. Link to comment Share on other sites More sharing options...

Nic Posted February 25, 2011 Share Posted February 25, 2011 Fit a new Walbro Fuel Pump (Part no. GSS342) and it'll be fine at 1.2bar, don't mess with the wiring, tried and tested 100's of times. Have a read of this -> BPU if you haven't already. Link to comment Share on other sites More sharing options...
