I recently installed the MSD 77303 along with a 7720. I have attached a screenshot of the run. This looks to me that the high side rev limiter is on when it should not be?
Any help on how to resolve this is much appreciated.
Have not received an answer from MSD tech at this time.
I can upload the actual file and settings if anyone wants to see it.

Thanks, Jim

I run the grid in my car. The high side rev limit is always going to be on unless the light blue wire or dark blue wire have 12v. Then the burnout rev limiter (light blue) or transbrake rev limiter (dark blue) are active. When no wires have 12v to them, the high rev limit is active.

Please upload how you have the grid setup for rev limiters.
 
Yes, I understand the the high side will be on. My concern is that it's activated below the setting(7000), looks like it goes into an active on/off/on/off continuously until i make the shifts. Then again for a second or so before the finish line. I'm trying to upload the files.
Looks like I don't know how to upload files or it can't be done?

here is a screen-shot of engine RPM(green) and rev limiter settings(blue). Starting line is 2600 and high side is 7000.
The previous one has rev limit active in light green(this is my concern).
Also the rev limiter settings in second pic.
I still don't have any answers from MSD/Holley
Thanks, Jim
