Posting this in different sections hoping to catch a snag:

Here it is short and sweet. Recently put in some id2000's, converted to e85, flashed on the base map, and starts up beautifully. Everything looks great while it's in closed loop and runs like a champ. The problem is once it gets to operating temp and switches to open loop, it just dies. Try to restart and it won't have anything to do with it. Fuel pressure is there, spark is there, sensors, timing, blah blah all that is there. I believe something is telling the injectors to stop firing once it gets to operating temperature. Let the car cool down, and it cranks right up again and it just keeps going like this. Anybody else experience this problem before?

 

What's your afr when the transition occurs? and just to be sure... did you rescale your injectors after the switch?

 

Yes injectors are scaled properly and can't recall afr when it switches over. I want to say it goes lean. I've pulled a plug, turn the car over and no fuel went into the cylinder so that's why I'm leaning towards an open loop issue causing the injectors not to fire

Doesn't the engine start in Open loop then switches to CL when the O2 sensor is within its heat range?.... just saying...

anyhow, can you share some more info? are you on speed density? what calibrations are you currently running? did you try enriching?

 

Yea I had it backwards in my op. Open loop everything is fine and dandy. Once it warms up and starts to go closed loop it dies. Yes I'm sd I'll have to check calibrations when I get home. I shouldn't have to mess with the sd calibrations they have been working just fine for the last 3 years or so

 

Well they do impact ur fueling. So I wouldnt be surprised if they did.
Try this, lean out the SD RPM VE cal and see if that helps. Drop it in the first three brakepoints.

 

So you think it's in the base map where the problem is and not something mechanical?

 

Problem solved. Thanks for the help.

 

what fixed it?

 

The car didn't like the MUT table that I flashed onto the Ecu so I put the MUT table that came with the base map back on it. Runs like a champ.

 

good to know!
