d15b7 sohc non vtec
1.5 liter d15b7 non vetec
i am having the same problem with my 92 civic cx, it rev limits ar 5.5k most the time sometimes lower.. several ecus tried....new distributor, wires, plugs.. timings been checked... i need to fix this
D15B7, 1.5 Liter SOHC non-vtec. 3.2 quarts of 5W-30 oil.
A D15b7. tt dezz nutz 1.5 SOHC
U need a cdi that has no rev limit
Because mod(x) is not "smooth at x = 0.Suppose f(x) = mod(x). Then f'(x), if it existed, would be the limit, as dx tends to 0, of [f(x+dx) - f(x)]/dx= limit, as dx tends to o , of [mod(x+dx) - mod(x)]/dxWhen x = 0, this simplifies to mod(dx)/dxIf dx > 0 then f'(x) = -1andif dx < 0 then f'(x) = +1Consequently f'(0) does not exist and hence the derivative of mod(x) does not exist at x = 0.Graphically, it is because at x = 0 the graph is not smooth but has an angle.Because mod(x) is not "smooth at x = 0.Suppose f(x) = mod(x).

On obd2 the rev limiter is in the ecm and works by dropping off cylinders to maintain rev limit.
there is a rev limit setting in the ecm so you dont over rev the motor
