Odd water temp readings?
Discussion
Plugged my laptop into the MBE on the PR6 & have noted that the MBE screen shows a far higher water temp by around 15C than then Radical dash display.
They are a short distance apart & could vary by a small amount I guess but that seems too much to be a true reading?
To try & confirm the temp I used one of those lazer type thermal readers on the machined spacer that the dash display takes it readings from & that was within a couple of degrees of the dash display, is that likely to be trustworthy?
Do I trust the dash or the MBE read out, bearing in mind if the water is 90C on the dash the MBE tells me its 105c+
?
Anyone have a generic part number or description for the temp probe the dash reads from?

Simon, when it was on the dyno at Radical 10 days ago James noted the same discrepancy & suggested the MBE reading is more likely to be the correct one so I have been adding 15c to the dash value & moderating temps on that basis but with the reading of the lazer gun being with a couple of degree's of the dash I am beginning to wonder............
Guess I shall have to replace both of the temp senders then!

what was James comparing the MBE reading with on the dyno? Ie was the engine on a dyno cell and therefore using a different temp sender to the one on the dash?
If so then do you have 2 sensors reading the same and the MBE one reading higher? That will determine which to check first.
ETA: don;t those laser thingies have to be shone on black surfaces to read correctly?
