simon gardner Posted November 5, 2012 Report Share Posted November 5, 2012 hi guys iv recently been doing some bits and peices to my motor , now its a v6 1mzfe toyota motor which is in my mr2 , the car was mapped last yr and everything was great ,the tuner who is well known said there was no pingingÂ , Â the performance was also great , now i have had to fit a catt to the car to get it through the uk mot , now since then im sure i can hear the motor pinging around 2000 - 3000 rpmÂ . it has stainless maifolds on which i know are a little tinny in the way they sound , if the worst case is that i need the knock block how easy or difficult are they to fit wire and configure , i have had a little play around in the area on the map were the pinging seems to be , but if im honest the noise doesnt go away unless i retard the timing so far that the motor seems flat . im maybe missing something here but can some one possibly shed some light for me as im getting very concerned. would the car need to go back on a rolling road or is it quite simple to set the sensitivity up for advance a retard in closed loop. any input would be greatfully received cause this is worrying me too much now , thank youÂ simonÂ Â Quote Link to comment Share on other sites More sharing options...
