How to get that Hemi cam to chop

These big hemi cam shops and tuners would like you to believe you can just toss one of their cams in and it'll chop. But that is not even remotely close to true. I have a lot of people that I have tuned their cars after getting big name cams and they hate that their cars don't chop like these websites tell them they will. So if you decide to buy a cam that isn't one of mine and you cant get it to chop, here is a video that will help you get that same chop they advertise. "chop" is a missfire that happens when both valves are open at the exact same time, if the cam doesn't have valve overlap it will not chop on their own.

Randy, I have a stock '14 R/T w/6 speed. I followed your instructions and this stock cam has a slight "lope" to it now. 😀 I know it's not the same as an aftermarket cam but I now know what to do to make my upcoming Scoggin-Dickey Stage 2 cam have that "lumpy" sound. I logged the first start and drive and, sure enough, the car comes to a near-stop/stop and the timing starts swinging. Thanks for the videos. I've learned a lot from them.

Under engine diagnostics you need to raise missfire rpm

I don’t have the airflow tab or proportional p/n adjustments on hp editor. Did they move this?

I have a early 5.7 (05) with a cam swap and manual trans. As I was following along I noticed my proportional P/N table is different then yours. Mine has rpm error as the rows and nothing as columns. That being said I am not sure how to set the values to allow timing swing. Do you have any ideas? Thanks!

Thank for the vid!! I tried those settings and my car has the choppy idle but only when it’s in drive and idling... in park sitting it doesn’t chop at all. Is that what it’s supposed to do when changing the proportional P/N table? I figured it would affect only park/neutral. This is on a 2006 Chrysler 300srt8 with a mild cam 218/212 113lsa, that doesn’t lope on its own(no overlap like you said).

I tried what you said, but it trys the chop but it just bounces up and down why would it do that? Also mine is fully built 392 stroker and stage 2 comp cam any ideas?
@kickblake
@kickblake 2 месяца назад
That's what the chop is, it's a consistent bounce in idle rpm.

I have a cam that has a decent lope, but not alot of chop. Would those exact numbers work, or would i need to adjust those numbers

When I do this at idle I don't get a chop. Only on drive and reverse I get a nice chop. Also, I get a P0300 can I turn this off or prevent it or just the nature of it?

on the idle torque spark proportional P/N table, how much spark on both ends is too much? I set mine to 44.99 and -44.99 on my 392 with a big cam
@Saavagerandy
@Saavagerandy Год назад
I guess I’ve never run into too much, you don’t need a lot on the outside. It’s the inside that has the most effect

@Saavagerandy
@Saavagerandy Год назад
The table has zero on the inside and negative on one side and positive on the other. The farthest extents of the table don’t matter as much it’s the inside numbers that do

@@Saavagerandy oh right. every value is -45/45, I was just making sure that if I decided to do something crazy like -64/64 that it wouldn't blow up the car lol
@Saavagerandy
@Saavagerandy Год назад
No it shouldn’t Be an issue and you also should need to go all the way that mush to get it to do that either. Your minimum spark table sets the spark limits so it’s not swinging enohhh probably because minimum spark is set to high

Would lesser #'s equal less chop? My 5.7 magnum sounds like a 68 hemi super stock barracuda using the numbers you suggest. Lol Sounds great, but a little overkill for what I'm looking for.
