Car has low revlimiter (4k)

[TheTacoMan]

Im running megasquirt with a turbo at 7psi, issue is that no matter what the revlimiter is set at it does not change. It will not rev about 4k, I replaced spark plugs, distributor, rotor and did not help at all. Im at a loss at what could be wrong.

Both MS and your tach reading same? Even just free revving the engine or only while driving?

i have the same issue at 6200. I think the crank pick up is loosing signal but i havent looked into it. I will be investigating it soon tho.

email matt cramer.

This typically is the CPS when there is too much gap, try loosening and keeping it as close to the trigger wheel as possible and tighten back up and see if it helps.

I adjusted my Cps and no more 6200 cut out. 7200rpm here i come.

I just loosened the 2 13mm and slid it as close as possible to the wheel, witch ended up leaving a 1/8 or so gap.

Good to hear

Sounds like it is my problem.

my car wouldnt pass 6200. When you hit that rpm, it would backfire like someone was shooting a .45 out the window. Now its clean till the 7200 limiter.

Also, my wire was getting chewed by the water pump pulley, so keep an eye on that too.
