I have a 1995 lt1 car that wont idle until it goes into close loop. the BLMs go up to about 148 then it will idle, when its in open loop and the BLM at 128 it wont idle, i have tuner cats what tables do i change to fix this?? thanks

 

Tell us more about the car. What injectors are in it, what do you have the constant set at. Is it running maf mode or in speed density. Do you have a log you can provide us with of it idling and warming up? Adding fuel at idle up to a blm of 148 is either a substantial vacuum leak or if your in sd mode the tables around idle are way off. Are you sure your cylinder displacement constant is set correctly?

Also what do you mean by it wont idle in open loop, it has to in order to get hot enough and stay running long enough to get into closed loop. Describe the problem for us a little more.

If you give us a complete list of mods, and post your tune and a log I will look it over and see if anything sticks out at me and tell you what to fix.

 

Run VEMASTER a few times when in closed loop.. should fix you right up
