Today i wanted went to get my car tuned on the dyno. Combo is a boss block windsor with highports, super vic and a fti hyd roller. When the cam was spec'd I specified a 7k shift point. I have Ed's recommended springs and I have lgm shaft mount rockers.
When we tried to make a pull to 7k the car shuts down at 6450. Its almost like it hits a really soft rev limiter. The a9l limiter was upped to 7500 and my digital6 limiter was set to 7500 also. Nothing worked The car will not rev pass 6450 no matter what we tried. I've read about people shifting stock computers past 7k, so what can I do to allow me to do the same?
I run a PMS with digital 6AL. If I set the rev limiter on the 6AL and the PMS to similar numbers, it makes my motor do similar things to yours. And at about the same RPM. I turn the 6AL rev limiter off and just use the PMS rev limiter. Then things are fine. I do still use the 2 step function though with the 6 AL. Not sure if that's what is happening with you though. I thought it was weird in my case. Have you tried bypassing the 6AL and just run the OEM hookup at the coil to see if it has any affect? When I ran the old style 6AL it didn't do that.
I have a digital6 I didnt have time to disconnect it to see how it would run. I'm going to do the crystal change and go back. When I do that I plan on disconnecting the msd to remove that variable.
I read up on it to, they say change the number from 961 to 768, is that the magic number cause I read that a few places, mine is set at 500 and does the same thing around 6400
