Hey guys,

Been trying to track down this issue for a little over a year now. I converted to speed density awhile ago, had this issue ever since. While warming up it will start up and run fine up until about 135-145 degrees F or 60 degrees C what i have noticed is it will go full lean and start to sputter and eventually die. If I feather the throttle to get it past ~66 degrees Celsius it will run fine until operating temp and warm. Scalings and latencies are fine. Just at a loss. Thanks for the help I can post logs and current settings, a video if requested.

 

Do you have logs and ROM?

 

sure, I'll try and get one up when I get to my computer

 

Here is a log and the current rom I am using. Thanks.

Looking at the data log, I don't see the AFR Ratio enable. Make sure you enable it so I can see this value. I did look at the ROM, did you convert the car SD? It seems to me map is pulling a lot of fuel from everywhere. Did you add the right injector latency? If you have any videos when starting the car showing the AFR that helps too.
