Int/blm
started the car up for the first time this spring. In OL I was 128/128, went into CL and INT dropped to 80 and BLM's went rich at 108. My wb read 13 to 14.9 throughout this.
I'm reading the same vac as I had last year so my assumption is I don't have a vac leak. Exhaust is also tight. Any thoughts?
thanks

Ed, Im no expert on this, but could one of your sensors be screwed up?..Maybe the O2 sensor or MAF sensor..? I have found sometimes strange things happen to cars that sit all winter..Things just oddly stop working , mice chew through wires, corrosion forms on connections...I would suggest checking the connectons on both the O2 and MAF sensors..
The reason you may be getting 128/128 readings in open loop is because some of your sensors don't start being used until you go into closed loop. I believe my car also reads 128/128 until closed loop..I would suggest making sure your getting normal readings from all your sensors via your laptop and also check your fuel pressure.You probably already know all Im posting, so just consider this a "Bump to the top" Good Luck..WW

I haven't dataloged just yet. this was my start up after the new tranny,TC and coilover project. I was watching my live data.
I believe the O2 is what drives the INT in the short term and BLM, long term. While watching my live data the O2 was crossing over its crossover points so my assumption is that sensor is ok.
Mine is a Speed density set up so I don't have the MAF at all (thank god..lol)
All the sensors seemed to read ok, but again I'll have to do a datalog.
I think I have 2 issues
1)CTS tables need tweaking
2) O2 swing points tables need adjustment
This is where I get lost... I'm not a tuner but I know enough to screw it up!..
