Engine/Transmission (1998.5 - 2002) edge comp or edge comp hot

[VolsFan]

Hi. Decided I am getting a performance chip and am pretty sure I am going to get the edge comp. Been looking for sometime for a used one and they just aren't there. Is the hot version worth the extra $$? I want a box that does timing to hopefully get me some better mileage, unhappy with my current mpgs more than wanting more power. Prices on these boxes seem awfully high, just going to bite the bullet I think

Thanks

Do you have any gauges in your truck? If you do I would go with the Smarty hands down. The Edges are good programmers and the Juice will make more power up on the top end if you tap the pump but they seem to have problems further on down the road where the Smarty seems virtually bullet proof. You almost never hear of anybody having a problem with a Smarty. Not only that, but I hear reports directly from Smarty reps that we will be seeing UDC (or some form of it) for the 2nd gens in the near future. Plus you get the high idle feature and a very capable code reader with abs readings/correction.

I've rode in trucks with the Edge Juice and if your into hot rodding and running the truck hard through the rpm range to redline the Edge will make more power. But if your into driving it like it's meant to be driven (towing, working, etc, the Smarty fuels harder down low and IMO makes better more useable torque in the engines working rpm range. The only real advantage I see the Edge having is if you don't have any gauges, other than that I feel the Smarty is more reliable and for what I need every bit as capable.

If I remember correctly, the only difference is that the hot Comp removes the 2700 RPM limit.

ok, great, sounds that the hot is something I don't need. I ran a smarty on my 99 briefly and I liked it, esp. since I didn't have to tap my pump. I have gauges; boost, egt and fuel press. , and a dual disk clutch, so good there. I don't need the little electronic monitor of course. It seems like most of the boxes on the market are geared towards 3rd gen and up. Also, Diesel4life, what is UDC? Yes, having a code reader is handy. I had a superchips and I thought it was lame but was nice to read codes, would like to have that capability again, and the high idle is nice too.

Smarty will only get you about 60 HP without injectors. The good thing it does is remove the TQ management for better throttle reaction but then it fells like the truck jumps out of the hole then lays down. Need injectors.

The others will fuel harder through out the rpm range but don't do as much for the TQ management. It depends on what you want to do, stacking a box with a Smarty and injectors is still the best way to get tunable power.

If you have a Cummins tech with an Insite you migh think about trying the 300 HP EMV tune and see what it does.

The big advantage of the Edge over the Smarty is the ability change settings on the fly, instead of having to do a re-program. Downside - if you tap the VP, you run the risk of instant death of the VP. It's rare, but it happens.

Increased MPG is all in the right foot. I can assure you that with any chip or programmer your mileage will drop in direct proportion to the grin factor. Even with the Edge on 1x1 (a little timing, less than stock fuel) you can get lower mileage.

Thanks for the info. , I have an edge comp on the way from a fellow member. Cant wait to see how it changes the truck. I don't doubt the fact, and know from past experience, that I will see lower fuel mileage at first just because of new found power. If the comp is anything like a quadzilla adrenaline ill be happy. Had a quad on the 99 when I was younger in college and it was awesome, but had it on a bone stock fuel system, vp didn't last long. Learned a lot since then

I just removed my edge with attitude from my 03. I will sell it for a very reasonable price but I do not know if it will fit the 01 engine.

Nope - completely different animal.

2700 RPM limit? There was no 2700 RPM limit on my 2002 HO - fuel shutoff was around 3150 or 3200 RPM. 2700 was the stock peak BHP RPM.

[Allnew2Me]

I didn't say that correctly, sorry.

What I meant to say is that the hot Comp allows the additional fueling above the 2700 RPM level where I believe the stock Comp only fuels to that level.

Thanks for the help. The edge came in. Just got it installed after the game. First off, the USPS has stepped up their game, got here from CA to MD in 3 days. This thing is crazy. And no, I wont get good mileage on this tank. I think I burnt 2 gallons going 10 miles. It smoked a lot, way more than I thought it would. I only have rv275s and this box. I will have to turn it down and drive responsibly. The light on the 5th level doesn't work but when I go backwards I have to press twice to get to the 4th level so I think it still works. Getting 30 lb boost easy. I assume level 1 or 2 is best for mpg gains?

 

[VolsFan]

ok, got an owners manual, didn't know how to get the sublevel for timing, had it on 5x1, explains the smoke

 

[BDaugherty]

With the RV injectors, I wouldn't bother with the hot setting. I had a Juice With Attitude on my '01 with the Hot unlock and it was great until I added 80hp injectors. Then it was too hot to really use and was so air limited that it really didn't add any power.

did your comp come with the waste-gate boost elbow? Im guessing so if you are getting 30 psi of boost. Now your next investment and it probably wouldnt hurt is some ARP headstuds. You DONT want to pop a head gasket!!



I was seeing around 19 +/- 1mpg on my 98. 5 with the edge comp on level 3, however I had a 3. 55 rear end. But it is hard not to keep your foot out of it!! be safe!!

 

[VolsFan]

Already had an elbow on the waste gate. I do not plan on pushing max boost regularly, but you know how that goes. The guy who bought my old truck blew the head gasket on it in nevada, had 200k+ on it though, something Ill think about. I have not driven the truck enough to know what my mpgs are like. Im guessing bad as of right now.

I have been running the comp on level 2 timing on 5 for best mpg got 18.2 on almost all highway. When I turn 3 And up its smokey. Is this normal? Even with it on 5 I still got 15 mpg but it was very smokey not something I particularly care for most of the time. Egts have been lower than I thought. The comp definitely only kicks in on the top end though but it's fun.

 

[PC12Driver]

The sub-levels don't affect timing. They control when the extra fuel gets poured in relative to the boost. For example (and I don't remember the exact numbers), a sub-level 5 starts ramping up the bonus fuel when the Comp "sees" 3 psi of boost. That'll get you the biggest bottom-end hit and the most smoke. Sub-level 1 starts the bonus fuel at 20 psi for minimal smoke and maximum lag. The overall maximum fueling is unaffected by the sub-levels, just how soon it gets there. So yes, 3 should make more smoke than 2.

The timing is a constant advance based off the original signal being sent by the ECM. The only way to change it is to turn it off (and I suggest doing so when it's below freezing - since it advances already fairly advanced timing). That's where the Smarty shined, since its timing advance was totally dynamic based on temp, pressure, and load, not just a fixed value.

 

[VolsFan]

Hey thanks! Thought sub levels were timing. I'm going north to Tyler county wv this wknd and will fool around with it more on that trip so would it be better to turn sub level down?

 

[VolsFan]

Also a smarty sounds great but I got the edge comp from a fellow Tdr member for a good deal may stack a smarty later on
