Ok so I have been having some issues with my tune for some time now and SSpdmon has been generous with his knowledege and sent me an updated tune that I was hoping was going to correct my idle issues, although his updated tune heled my idle surge the vehicle will not idle down until my VSS is 1mph. If I change the B4311 and B4312 to a higher value then the vehicle will idle down at that value. i am not sure why or what to do to fix this.
Next issue. This is the one that really has me stumped. I am having an issue with my AFR going lean by one whole point. It is really wierd I can drive along keep a neer steady TPS value and my AFR will be 14.63 then with the addition of about 3% on of the throttle my AFR goes to 15.63. I have done Auto VE three times for these cells and it still remains the same. I am including a copy of my tune and a short log of this. My wideband is a NGK AFX so a custom pid is needed to watch the graph. The equation for it is ({EXT.AD2}*1.4)+9" Around frame 275 is where things start to level out then goes lean around frame 660 does the same ting for a longer periodAny help is appreciated:grin:
Thanks,
..RJ..
Also might add that I have done very little ve tuning above cruise speed so please ignore that part of the VE table
