It's been a while since I last scanned my car as it was seeing only blimps of KR before. I just installed my new 72 mm TB and let it learn for a week, and after a scan tonight looks like somethings up. I'm seeing O2's steady then just dropping, along with my IPW's too. Now in my file I've got more then enough fuel commanded too keep the O2's at least at the 940 level so this is weird. I've inserted a scan of just the problem area I'm talking about

97 regal2 from monte0 -- Scan Depot dot net

It's almost like fuel pressure just took dump while in WOT. What do you guys think??
 


Their is one other thing that might be a issue I'm thinking...my IPW table is stock and should be for stock injectors...but 97.5 is a weird year and my IPW table is set to 106.3 from 0-100 kpa. Now on every other year regal their scaled from 219 (kpa) to 205.84(100 kpa) Is this the cause of it?
 
I was just trying to pull more info out of you for someone else that sees this smarter than me.:)

Do you have an IFR table you can load to try?
 
I have later bins from 98-2002 I could pull the table out off I could try, but isn't their a reason for the weird 97 IPW thing with the Granprix's and Regal's? (gotta love the oddball cars :D)
 


could it be a prob with that resistor thing for the high speed setting of the fuel pump, like it isn't switching to the higher mode?

Oh, and it looks like you only are getting knock when the LTFT goes negative

I'm not sure, I'll bypasss it and scan to see if it goes away....and yea, isn't it weird that my LTFT's are going from + to - and when it goes - I see KR.:confused:
 
problem solved guys...ended up having a bad flash because my keysane adaptor was having some kinda issue with the serial to usb cable :rolleyes: But either way it's much better now just a tad lean up top but nothing a little tuning cant fix.
