One handed jumpy video!
It revved perfectly up to 6,500 in every gear up until the normal rev limiter actually came in. BUT then after switching the ignition off it was back to 5,200 again. I then had the engine idling, pulled the diff sensor plug off for a few seconds and then plugged it back on again: Rev limit was back to 6,500 again! As you can see both the odometer and rev counters appear perfectly normal.
Peter suggested that I go through all the wiring to double check it's all okay. This will mean taking off the scuttle which I think I'll wait with until after a Scania race day which I have booked for the 19th of September down in Linköping. I can always unplug the diff sensor to reset it!
Maybe its a fuelling issue, perhaps the G force is over coming the fuel pump? However it doesn't feel like a fuel cut, (my evo used to do it, that was more like BANG no power) but I've noticed if you keep your foot in, the revs do slowly creep over the 5500 mark.
ReplyDeleteDave suggested once that it might be a fuel pick up problem, but I ruled that out with a full tank of petrol.
