Has anyone defined their speed limiter with a trap speed?
In the quarter mile, my trap speeds have consistently plateaued now around 127mph. I know the indicated speed is exagerrated and it was indicating 130's already when my trap speed were 120ish, so now I wonder if I'm being limited by the ECU.
There isn't a distinct cut in power and I'm not in top gear. From the dyno graphs I've seen I thought only 5th was limited like that, but the magazine reviews did all report they were hitting the soft limiter.
I also don't know whether the ECU actually limits based on the exagerrated speedo reading or something else.
My ETs are consistently 11.15 to 11.30 on street tires at a 4000ft elevation track and our Density Altitude was a harsh 7300ft last time out. Despite those variations my top speed hasn't been changing much.
