Thanks for the reply Dave seems I was way to cautious I will adjust the
programming for
EGT = 1800
CHT= 400
oil temp = 280
water temp = 245
I can mount the EGT probes all in line in a straight section about 3 " from
the exhaust port
I will record the temps over a couple of runs and average then look at
setting the parameters with some data for this vehicle thanks again mate
