i've came across some threads and if i'm understanding correctly, the programs when applied to the s.o. (235hp) will bring the output up to that EQUAL with the h.o. engine on the same program? can someone explain?......thanks........also, does the smarty "save" the stock software from the ecm when you switch out programs or does it have it's own stock version loaded already, so your "original" stock program is never the same?

Yes it will. the so motors, cali or not, are basically the same engines with detuned computer characteristics. When adding a programmer, it remaps the computers and adds the same exact program, therefore bringing the power levels up.

so if he were 100 hp less than an ho (round #) and loaded level 2 on a jr he would see 170 hp over what he had originally

namotuman

that's right to the point......if so, that is a real bonus!

BONUS!!!!!!!!!!!!!!!!!!!!!!!

If he has a CA emission SO motor (Like I do), then at the Smarty JR 100hp level he would see 170 extra HP. The CA SO motor is 235hp.. HO is 305HP.. a difference of 70hp + 100hp smarty jr = 170hp.

Like Bob said-- BONUS!!!

namotuman

looks like i get the bonus!!

Exactly. A cummins is a cummins!!! Everybody, even s.o owners, can enjoy the Smarty craze!!!

cool i get the bonus too than, i,ve been wondering about how much extra the SO gets brought up with the smarty. good post.

Aren’t the smarty numbers the horsepower increase at the rear wheels? The Cummins ratings are at the crank, so actually the Jr brings the engine up more than 40/70/100.

Having an SO plus Smarty = FESTIVUS for the REST OF US!!!

Yes, the Smarty brings power levels up to ho levels in the same process. It is just computer tuning that makes the HO different from the SO, when you put in the Smarty program its the same program, so same power through to the same drivetrain. Only differences will be if there is a SO with a 47re; only then it would be suggested to be even more easy on the truck.

Well... yes and no...

They baseline the (stock) truck on the dyno and get RWHP numbers... then check Smarty power output at each level... the increase advertised is the RWHP increase. This does not necessarily mean that it was a greater increase at the crank. The parasitic loss through the drive train is to a limited degree a static number (but can differ greatly truck to truck) as the power levels increase. The crank increase is not necessarily going to be that much more than the increase you see at the wheels.

I see how you are looking at it. There is a horsepower delta or change; it may not matter whether it is at the crank or at the rear wheels. Higher horsepower means more force on the drive bearings and gears (which means more friction to take away power), but it might not be significant.

namotuman

hooray for the bonus! now what about the stock program part....will i end up w/the h.o. or the s.o. stock program? will the programmer keep the oem program or load it's own version of the "stock"?...........thanks, ned
