Cat 3406E in 2017 peter 579

My mechanic acquired a schematic for my truck, bought a Cat ECM plug and wired it. Everything works even the truck functions on my smartnav.

 

Very nice.

 

While we are on topic of 3406e, what serial prefix is the one preferred and why? 2ks, 5ek and etc

 

If I was gonna build a motor I'd look for an acert. Bxs is the easiest acert to turn into basically a 6nz. Otherwise I'd go with a 6nz, 1lw or 2ws.
Acert block is stronger and just all around better I believe if built right

 

Bxs is the only big electronic Cat I would AVOID!
The ECM on a BXS is the only one that can’t be “properly” tuned.

 

I drive a BXS. It’s great engine and it’s “properly” tuned.

Feels good to be passing other trucks on the hills while loaded and passes Government emission test everytime.

Actually passes e-test better than the 550 Cat tune that hogs fuel and no more power than our 475 3406E.

 

I don't know about all that but a bxs is the easiest acert to hang a non acert ecm on.
