Except it's inverted, so the value at 8015 would have to be twice as big ... 460.  We're clean out of bytes.   I think the solution would be to double L008B in the VSS calc.  Do  JSR, ASLA, RTS etc.

I'll take a guess at just setting the pulse/mile to half what it is now. 


L8015: FCB 230 ; PULSE/MILE RD SPD CONST ; ARG = 921600/VAL

Sorry i have been away for a while.. rx7 or rx8 is now safteyed and on the road.. got a problem with the vss.. the mazda vss. is twice the speed of what the ecm wants. ie ecm thinks 50mph is 100mph. This causes some problems with tcc ect. I am running aujp code in a 730, but while it was in my truck i had it setup for the optical sensor... anyone got any ideas on how to make this accurate ?
