Msd 42351 vs 2530

[800750]

Anyone know what the difference is between these two msd brains?

Well, one has a 5 digit model number vs the other being a 4 digit. The sum of the 5 digits is 15, the sum of the 4 digits is 10. So, the 5 digit one must be better............ At least 50% better..............

MSD Total loss master thread

Ai search says: 2530 does not inherently offer the detailed timing curve programmability found in the 42351.

Ai as u know can contain wrong info sometimes.

I think and I can also be totally wrong here that the 42351 has three stage retard and the 2530 does not , most of the searches on the 2530 come up empty .

I think they are the same in my research. Best proof I have is the file name for the 42351 manual is 42351.pdf but references 2530 in the title. They have the exact same dip switches. I think they just printed 2530 on older brains
