wow I did not know that I read some where that the black box was hard wired at 5800 forget where seen read it and I do not know why any would think or say thatThat is not correct. Black box can easily be reved higher. The secondary "rev-limit" is actually the ignition coil dwell being too long at high rpm. I have had the black box running 6,500.
At one point it was not known what made the black box act like it had a secondary rev-limit.wow I don know that I read some where that the black box was hard wired at 5800 forget where seen read it and I do not know why any would think or say that
In 91 on the 4L80E trucks.The speed limiter started between 92-94 I'm not sure of 1st year but I do know a 94 has one

I believe that to be correct. The 91-92 4L80Es used that ECM for both the 350 and 454.16147060?
Is BAMY a modified .bin?91 would not have been the 7747 as it came with a 4L80E. Should be IIRC a $85 bin BAMY.
BAMY was a 454SS cal from memory.Is BAMY a modified .bin?
No speed limit and a 6375 rev limit according to TPro.
