I have the original Catcher and i was looking for some info on the specs for it. I am curious as to how they compare with the new smarty. I have found the specs for the new smarty and what each power setting does, I want to know if there are any major differences between the original catcher and the smarty. From what i gather the new smarty does not defuel past 2700rpms, i am wondering if the origianl catcher had the same feature. Thanks for your help

 

From what I understand, Software #9 is exactly the same as the original CaTCHER ECM. I'm told that #8 is the "Special CaTCHER" (no timing).

 

my origianl catcher must be level #8 because i have a comp box which is timing and fuel. The reason i ask this question about whether or not the origianl catcher did not defuel past 2700 rpms is because i just upgraded my comp to a Drag version and i am wondering if i will see any inprovements power wise. The drag does not defuel past 2700 rpms like the regular version did. Thanks for the info

 

Only power difference I saw between a drag and normal comp (stock ECM) is an extra 40hp after 2700 rpm. Both peaked the same. I tried this on 2 different trucks and it was the same outcome.

 

A smarty will fuel to 3550. That really wowed me when testing it when I looked down and saw the tach dead on 3500 Get your truck warmed up good and see how high you can rev it and then you'll know

As longs as the torque doesn't drop too quickly the additional RPMs would yeild higher HP. Lets say you had a perfectly flat torque curve @ 500 ft lbs. At 2700 rpm you'd be at 257 hp, at 3200 you'd be at 305 hp and at 3500 you'd be at 333 hp and just for kicks if you made it to 4000 you'd be at 380.

My point being that BB's 40 hp is pretty reasonable

But reading through some of your posts Mr CTD2001 and seeing how you're @ 458 hp and looking for 500, I'm not sure if you'd see a big gain if that last dyno was catcher comp. Look at your dyno chart- at what RPM does the torque start to dive? I'm thinking that if it pulls hard to the end then the drag upgrade might not be much help.

 

thanks for the insight, i am looking right now at my dyno chart, and the max torque was made at 75 miles per hour, then from there on it started to gradually fall. My max Hp was made at Approx 83 miles an hour and held steady all the way to 105 then it began to fall. I am not sure why Rpms are not listed on the sheet, Torque on the Y axis and MPH on the X axis. I know when i am running down the road that 75mph is right around 2100 or 2200 rpms. I am not sure if it is different on the dyno. Any more insight would be great, thanks
