OK, well, here is the thing.
first. make sure you have the REV LIMITER turned off. make sure you have the RPM set to like 25500 for soft and hard cut. the reason is, when RPM SPIKES, it usually goes to like 15000 so if you set the REV LIMIT to like 7000, you will keep getting fuel cut, or spark or both cut!

Change that.

Now, when I did my SPARK setup, I got an extra connector for the coil. so I can switch back to STOCK ecu anytime. if you have the REV LIMITER set to MAX high, then with just fuel, you will not feel the buck! the RPM will still SPIKE! but you won't feel it. (check out hte other post that corbin posted) it's the same problem we are having!

But the reason when running spark, we feel the BUCK, because if the RPM SPIKE, the one ignition it changed or missed we will feel for sure! but when RPM SPIKE when only running fuel. a miss of fuel won't make a big difference for us to feel the BUCK.

So I believe our MAIN problem now is the RPM SPIKE problem.
And I tried EVERYTHING I can think of already. up to 0.1uF capacitor, and shield cable. I will try to ground the crank sensor as well to the MS and see what it will change.

So which wire is the ground for the crank sensor? do you remember?

Thanks.
