Thank you for all the help so far, does this look right?
It looks quite funky, I need to double check that you have the right map.
A standard 180hp engine usually looks something like below, with engine speed from about idle to 6.5krpm's. %dk-axis seems correct though.
50,000 59,000 90,400 110,400 135,200 155,200 165,200 175,200
55,200 65,300 97,900 117,900 142,300 164,300 174,300 188,300
60,000 69,800 104,600 128,000 152,200 172,700 186,400 200,600
66,900 77,200 119,100 148,900 174,200 193,500 204,600 219,500
68,700 83,400 137,300 185,600 229,300 258,700 291,800 342,800
69,500 86,200 144,100 209,100 262,500 311,200 388,300 524,400
70,100 88,300 145,700 231,700 289,800 344,600 461,100 661,800
85,000 103,200 149,000 274,700 339,500 399,200 533,900 746,100
It also looks quite strange to have the last cell at over 9krpm's.
