K20A2 Custom map , car starts but goes off , see log files

Post by RoadsterAlex »

Hello,

I wonder if someone could check why my engine shut down after few seconds based on my log files
I have the feeling its my map sensor but maybe someone who can confirm this?

newest file: ran a bit longer 2
after that: ran a bit longer, starts log 2, data log starts but goe off, latest data log file


In this order.
Doesnt go above 600 rpm
IN my Runs a bit longer i had to hold the pedal otherwise it would shut down,

I use an external AFR and connected this to my analog 0, and ground to ground as ive seen before i had to do (prosport gauge)
Only thing i can think of when i check my log files thats its my map sensor, i had issues with it on my old ecumaster ecu, thats why i bought an hondata ecu.

Could it be that my map sensor is broken? as it says "170-180kpa" all the time, other weird thing is the 20.43 AFR all the time? while when i shut engine off it goes back to around 14.7 unless i read the logs wrong?




Thanks in advance

Edit: I adjusted the injector duty and the car runs now but it always runs around 1900 rpm and my AFR on both gauge and display on my car is showing and keeping 14.6/14.7

If the MAP sensor has been plugged in incorrectly even for a split second then it will be damaged and have to be replaced.

The car is running at around 32kpa idle.
But idle goes up and down all the time

Could that be the map sensor as well? Because it does read

Try anther map sensor to rule out the issue as the map sensor.

So I replaced tps, map sensor, removed whole idle air control valve, idle air assist everything

Car is a bit more stable now.
However my AFR (Prosport) is still 2v off?
My AFR is too high and doesn’t seem to update a lot

So what your saying is that the AFR you see on Hondata and on your gauge is different?
