Runs fine when it's hot (ambient), bogs when it's mild
#6
Stock ECU with Bipes. Greddy kit with no mods. I've replaced or swapped the ECU, ISCV, FPR, AFM, ECT, yahda, yahda, yahda.
This first occurrence was about 8 months ago. Maybe 15 seconds of bogging when hitting closed loop. It was so intermittent that I didn't bother checking it. Gradually it started happening more often, mostly when I ran, turned off for a little while, then ran again.
Now it happens almost all the time, except when it's hot outside. Sometimes for 10 to 30 seconds, sometimes all the time till the engine is up to temp.
I have a MSPnP I plugged in. One time the MAT and ECT gauges went bonkers, reading all over the place but mostly pinned. The next time. Normal.
Maybe wiring? But why temp related? No CELS. I got a couple when it first started happening, but lost them in a battery run-down.

Shall do. I measured continuity from both the harness plug and the connector but still had the problem. Both measured fine. Maybe I needed the ECU to throw a CEL before it would forgive the ECT for its past transgressions... Try pulling the wire, running it and plug it back in. Stranger things have happened.
Maybe just jostling it around... Maybe it will start bogging again tomorrow.
