Engine/Transmission (1998.5 - 2002) Edge EZ vs Diesel Dynamics TTPM

[Lube Man]

Wow, getting some great responses to my earlier request concerning the Edge EZ. But now my decision is further complicated by the TTPM. I understand that Edge makes this unit for Diesel Dynamics. Why did they specify different performance requirements? They claim no EGT rise with the TTPM. Also it appears they do not use a waste gate elbow like the EZ offers. And with only 50HP and 100ft lbs I am thinking this might be a compromise to get more power but not as radical as the EZ. Please comment. Especially interested in what TTPM users have to say.

If I am not mistaken I believe DD unit has less aggressive timing.

 

[Fred Swanson]

Correct. A little less. It is almost impossible to feel though.

 

[outlawram]

if you want a ttpm, I have one for 300 bucks. Diesel dynamics does use a boost elbow. It came with it . Mine is for a 99

 

[BLACKRAM]

EZ now owns Diesel Dynamics. The TTPM has a slightly less aggressive fueling curve. It works great. I have had mine for over four years with zero problems.

I guess I'm really looking for some feedback as to why a person would buy one unit rather than the other.

I've got the EZ and if I were to do it all over again I'd go with the TTPM. Less aggressive timing/lower EGT when pulling grades is the main reason.

Lubeman, I picked the DD module over the Edge for two reasons. The DD has less total advance (so I was told), I have a 5er that goes down the road about 10,000 llbs and tow in the Sierras some. I thought a bit less timing would be better. Also, on the DD box, one of the settings is timing only, no added fuel. The Edge does not have this option. I thought the timing only option would be better down the road if I ever added bigger injectors, I would have an extra fine tuning option available. A timing/boost fooler box that I can disable the extra fueling if temps are too hot with larger injectors.

I bought the TTPM because I happen to be in Vegas and drove by Diesel Dynamics, I had never heard of Edge until later. I also like the less aggressive timing for towing, even with 13,000 hooked up in the Sierra's it never got over 1100 EGT, great towing power and it gets better milage! No complaints here!!!

What Edge & Diesel Dynamics Have To Say!

Both Edge and Diesel Dynamics say that the EZ and TTPM modules are identical except the way they are jumpered. The main difference is that the TTPM is set up to allow a timing change only if the owner elects to go to bigger injectors in the future. They both state that with a stock engine the EZ and TTPM should achieve the same HP/torque levels. The reason for the two companies showing different HP/torque ratings is because the tests were done on different dynos on different trucks at different locations (elevations). Other than that they both state the units should yield identical performance.



Anyone care to comment on the above from their own experience?

Lube Man, thanks for the updated info on the boxes.



Only info I had when I purchased mine was from the folks that post on the TDR. Was reported the EZ netted more horsepower/torque by using more aggressive timing and fueling over the TTPM. I knew I'd eventually install bigger injectors, therefore opted for the TTPM. I prefer to make more horsepower/torque with injectors versus a fueling/timing box. Easier on the injection pump and wallet that way.



I wanted to be conservative on mods because I was only looking for a little more power/torque to pull a trailer up 6% grades, while controlling EGTs. With the TTPM on #2 setting and EDM 1. 5s, I'm able to slip the clutch. Had to adjust the box to timing only until I install a new clutch - any suggestions/suppliers/installers for a clutch? EGTs have never been an issue (1,200 degrees max), even at 10K foot elevation. My tow weight has never exceeded 8K pounds, however.



I've been running this box for 40K miles now and really like the performance gained from it - and will even more so after I get the clutch replaced. Too, the TTPM came with boost elbow restrictor fittings for the HX and HY turbos.



Good luck with your decision, many good options out there.

First of all, my knowledge of timing and fuel delivery is far below that of many people on here, but it seems to me that if the only difference between the EZ and TTPM is the fact that the TTPM will allow you to only run a timing advance with no extra fuel is kind of a rip-off considering that an EZ can be bought for around $400 now. eBay always has great deals on them and I've found several sites on the net that are a lot cheaper than some of the more mainstream diesel vendors.



So your paying a lot more money for less advertised HP/torque gains and the fact that you can run timing only - just doesn't really make much sense to me. There's a guy out of California on eBay that will sell you an Edge Comp for less than what you would pay for the TTPM.



Diesel Dynamics claims that their injectors work best with their boxes and vice-versa, so if I was to ever get a set of DD injectors, I would probably look into getting a box from them. I feel like there must be something else different about the two or DD wouldn't make these claims.



I was lucky enought to get an EZ at around $370 from a friend who owns a muffler shop so the choice was obvious for me.



Good luck with whatever direction you choose.

How much technical support do you think that guy can provide? When something goes wrong, who are you going to call? Guys like that hurt the entire industry.

 

[outlawram]

Keith,

No, guys like your company charge to much. Talk about inflation! I have a ttpm from you and on the 10th I will be getting a edge drag comp for 585. 00 or the regular comp for 446. 00 my choice. If diesel dynamics can do that deal they might have my sale!

 

[SnoKing]

Well Keith came to the tread without answering the question about if there is a difference in the amount of timing. I would like to hear that question answered. SNOKING

Guys like that only hurt your profit margins, not the industry.



Edge has great tech support. I guess I would call them. I would probably have done that anyway - always go to the source. I really wouldn't have expected that guy to know anything anway. And who needs tech support when you've got the TDR? I couldn't imagine having a problem that the guys on here couldn't answer.



I'm just letting people know their options. If your product is so much better, tell us why and maybe you can justify the price to us instead of getting upset about me trying to save a guy some money.



But please don't let this get into a shouting match between you and me because I would like to order some injectors from you guys in the future and it's important that we stay on each other's good side. If you'll read my post above, I stated that I would probably use your box if I had a set of DD injectors.

Actually, we charge the lowest ALLOWABLE amount. Edge sets a lower limit (10% off MSRP) as the lowest price a dealer should sell it for retail. All these other guys that are selling it for less are jeopardizing their dealership and that of their distributor. Edge IS checking into it, to try to keep the playing field even for all the dealers.



MSRP is $699 for a comp box, with $629. 10 as the lowest allowable sale price. We sell it for $630. How is that out of line? Buy it while you can.

To answer the question, the only difference is the timing as far as the programming is setup. Power-wise, they are the same. Our power ratings are what we observed as the lowest gain.



ETC: 50hp/100ft-lbs at peak, 80hp/225ft-lbs in mid range (2000rpm)

ETH: 40hp/90ft-lbs at peak, 75hp/175ft-lbs in mid range (2000rpm)



This stuff has been posted multiple times, which is why I didn't originally respond to the question.

 

[KLockliear]

Don't you think that profit is why we are in business? We adhere to the pricing guidelines set forth by our distributors, as these other "kitchen table" distributors are supposed to as well. The bottom line is that if we don't make our profit, we don't have the money to do the R&D on the new stuff. It's not cheap, let me tell you.

I'm just letting people know their options. If your product is so much better, tell us why and maybe you can justify the price to us instead of getting upset about me trying to save a guy some money.

It's the same product, that's the point. They are not adhereing to the pricing limits they agreed to when taking on the line. I stick to what we have to do. Eventually, they will be tracked down the cut off, one by one.

But please don't let this get into a shouting match between you and me because I would like to order some injectors from you guys in the future and it's important that we stay on each other's good side. If you'll read my post above, I stated that I would probably use your box if I had a set of DD injectors.

I'm not on commission here, so I don't really care what you buy. You will buy what you feel is the best injector out there I'd imagine. Buy our product, you get our R&D, knowhow, and I guess indirectly, you pay for my time here on the TDR. I know a lot of vendors have left this board from when I started on here, because you get beat up, then you guys start threads like "who's got it the cheapest" and go buy it from other sources.



Perhaps I should also just stop posting here, since after the info is found out, the cheapest vendor is the next move.

Keith, even Piers Diesel Research sells the Edge Comp for less than $600. I consider Piers to be probably the most reputable company in the business so I don't think that it's a matter of "tracking them down. " I've never seen anyone charge $629. 10 for a Comp box. I personally think that you're trying to defend your higher prices.

I really don't understand why you think you're getting beat up. All we asked you do was answer the original question but when money got involved, you got all defensive. It's just simple economics - you can't blame anybody for trying to get the best price on something. I would hope that someone would buy from the cheapest place, especially after you have confirmed that the products are basically the same. They would be pretty silly not to, don't you agree? I would be willing to bet that the consumers on here aren't really worried about whether Edge slaps their vendor on the wrist for selling their boxes for less than you claim that they are supposed to.



By the way, telling a potential customer that you don't really care what they buy isn't a very good way to attract business considering that this thread will be read thousands of times. Just a tip.
