Edge COMP vs. TST Powermax 3 with a lil smarty tossed in..

[LOtero]

well i have now had my truck set up pretty clost to how i want it for a little while now, yea i know i know slippery slope, but i just pulled off my edge comp box to swap it for a TST powermax 3. my initial impression is the comp runs harder down low and about the same up top and makes alot more smoke. the TST gets alot hotter and seems to be laggier. i dont tow, just race, and the comp took me down the track in 14. 3 seconds, i stacked the comp with a smarty box... absolutely no change, i thought that was kinda wierd. so tomorrow night i am going to the drags again to run some times and hopefully will be able to borrow the smarty to see how the TST/Smarty runs. .



Has anybody run comparisons between these two boxes?? or ran a similar truck like mine with a TST stacked??

I know when I stacked my edge comp with the orig. smarty I also had great bottom end but the top end was not there. My original dyno with twins wouldn't go over about 320 HP. I removed the smarty and back to original ecu and bingo hit 500 hp. So no more smarty.

If you have a comp and a TST, you could use the comp in ez mode stacked with the TST and then add a smarty on 8 for the low end fueling. I have heard others had good luck with this setup. If you have it you just as well try it.

i was wondering about that!? wondering if i can stack the comp without the pump tap wire on the TST but dont they both plug into the map sensor?

have you run it without the smarty and then re-run it with to see if the smarty gets you a better ET. ?

I am very interested in your results. It doesn't surprise me that you didn't go any quicker when you added the smarty to the comp. Low end fueling means nothing to me at the drag strip. I leave with between 15 and 20psi depending on track conditions, and it hits 65psi before it shifts into second (I can hear the blowoff valves). I have seen multiple messages that the smarty defeats the defueling until 4000rpm. I would like to hear from someone that has tried it at the drag strip. I don't need any higher then 3200rpm except at the finish line.



Keep us posted!

i ran with just the comp, got to about 1400 by the end of the drag strip at 14. 33, hooked up the smarty on 8 ran a 14. 35 at 1550 deg same MPH. so no gain other than heat and smoke. i will see if i can borrow the smarty tonight to run stacked with the TST. .

There are others running the TST/comp stack. I have personally never run it because the comp by itself is working very good. Plus I don't think the HTT 62/14 would be very happy with much more fuel.

I am supprised no one has chimed in. Do a search for the stack and pm someone who has done it. They should be able to give you a better idea.

While I have not run at the track I know more than one guy that went faster with the smarty as it defeats the defueling on ****s of the transmission.



Now my seat of the pants meter tells me that my truck has a better top and bottom end with the smarty. I have seen my truck go past 3500 rpm several times and the speedo goes from 60 to 90+ in the blink of an eye.



If you have a comp make sure you are not running a smarty version that has timing. Try level 8. Also don't run the comp on 5x5, back it down till the smoke clears.

I am having trouble with this 320 ---> 500 jump. 180 Hp is alot. You are the first person I have seen to post such a drastic loss of Hp. Most have said the loss was typically around 30 Hp.



You sure something else was not changed? How did the torque chart change?

Anyone?



I was wondering the same thing. I was considering trying an Edge EZ or equivalent stacked with the TST and the Smarty.

Jim,

Originally I had edge comp and the orginal smarty. I had a B2 and 100 hp injectors and never could get the dyno over 320 hp. I went with twins and then it jumped to about 350 hp but at the top end the fueling was not there. I removed the edge thinking a problem and used a friends drag comp and still no changes. I reflashed the ECU again and it jumped to 410 hp. Your right about going to 500 I forgot that I changed injectors again and thats when I went over 500 hp, sorry about that. So as far as the orginal hp pre-twins I can only assume that I was way off only due to comparisons with other owners with similar mods prior to the twin set up. I can only pin point the issue with the "catcher". Even my mechanic at Immler Diesel was stumped about the non-hp increases with my mods. We were both thought this might be a ECU issue is why I did the reflash. Also the catcher was supposed to be the upgraded version so not to mess with the timing and leave that to the edge. Hopefully this all makes some sense.

you can plug the TST in between. That's what I do. I upgraded to the TST and decided to hang onto the Comp when I got the revelation to try the Comp in EZ mode for dyno'ing as some reports say you can lose hp with the Smarty on higher hp trucks. I like having the instant in cab adjustability of the timing and fueling between the 2 boxes. I still run the Smarty on even #'s.

use the TST for fuel then comp for timing , so hook the tst to the map sensor then from there hook yr comp to the main harnes , I did this with a redline hotjuice and a smarty , it had lots of timing and smoke , too much realy so i sold the juice

well i finally ran the combo last night! it was a really fun night and i wish i could post videos, killing GTs, Camaros and ricers never gets old! there were alot of diesels there. . anyway i ended up stacking the comp in EZ on the TST and ran 14. 3-14. 6, so really all i got was more smoke and 1. 5 mph at the traps. running just the TST netted me a 14. 56 and running just the Comp tapped got me a 14. 30. never got a chance to hook up the smarty, but i think i am going to stick with the comp, not only because its a hair faster but because i like the way it runs and the adjustability of it. im going to sell my TST to a buddy of mine, the same one who runs the smarty and 275s so i will work on getting him to the track to run it. . his truck is an 01 with 275s smarty goerends bros transmission and soon to be a TST PM3.



do my times sound right with the comp in EZ mode on the TST?
