Hey guys need some help
I have a built car - running narrowband simulation with an innovate MTL-X
Car looses all throttle response and typically will stall out if im rolling to a stop.
*logs show a flat 22.4 AFR - Since im running narrowband i think that is the cause of the lack of drivability. (but why is it happening)
Happens intermittently
typically on a non-cold start drive
Thought maybe it's a Voltage issue but I don't think so - kept an eye on logs and only see low voltage when car shutting off / starting up
Thought maybe it is heat related - it does this a ton in city driving, but once I got to the highway and got some good airflow, i pretty much drove 30 minutes with no issues. I recently did some heat management mods to potentially help this but it's still happening. I was previously hitting 210-225f at times but this issue wasn't necessarily happening then. It currently happened probably 200f-220f
I've replaced the sensor with a new bosch and recalibated and no change.
any ideas? Is it due to the airflow/heat? The fact that when driving at 3.5k rpm (on highway) doesn't give me any issues seems to lead to that..but why.
*this may be an incorrect page for this but may be related!
video below for example
TIA!
