Hi all,

ive been trying for a few months now to get my scanguage calibrated. I followed all instructions to the letter, as far as I can tell, but many fill ups later I was still having to adjust the offset percentage by around 100%. I tried messing with diesel a and diesel b today on the drive to work to see if it changed the gph, but it was really hard to tell. However, most of the time it seems like the gph reading is way lower than it should be. Even beyond the typical 0 at idle. Is it possible that my truck is incorrectly reporting fuel consumption? Is there any way to test or calibrate that? Anyone have any idea what I'm doing wrong? I love the scanguage for its other features but I would really like to be able to see accurate mpg data....

Most tuners fuel under the stock curve, which gives you more low end torque, which in turn gives you better MPG IF, BIG IF, you can keep your foot out of it.  The more power you shove down low the more MPG you will get within reason.  

 

Not a bad price.  You won't hurt anything by running it on 65 hp mode.

Mike, 

How would the power puck compare in terms of hp and tq numbers and fuel economy?

They all the same. 60-65 HP period without a wire tap. Then is once you tap the wire you gain more control. You can directly modify the fuel signal for added timing and fuel. How this is done is adding more fuel pulse before time or just extending it.  So now that the window of ability is open now your capable of controlling more so. Personally, I think Quadzilla has a much better tuning abiltiy over Edge but still Edge Comp / Juice holds it ground rather well.

As for all the other non-wire tap modules and programmers you are stuck playing by the rules of the ECM / VP44 and can't exceed so you're limited on timing and fuel amounts so not to create errors within the system. Wire tapping now bypasses this and allows for direct modification of the signal this why there is an increase in power.

Now that being said being I'm working with the OBDLink LX scan tool and I can tell you stock Volumetric Efficiency is 63% for ISB Cummins. Now after figuring out the effect of the Edge Comp on 5x3 its a 77.5% volumetric efficiency now. Roughly 14.5% gain.

Very interesting info! Thank you for explaining all that. What do you guys think would be a fair asking price for my smarty S03?

I think I see them go for ~$400-$500 on CF

Ok thanks I didn't think I could get that much. I had one guy willing to go $325 but I didn't want to go that low. Not yet anyway. I really need to find someone who wants to trade lol. I think the comp and smarty and pretty equal as far as value. 

Scangauge doesn't seem to calculate idling into trip mpg. Soon as you start driving the cost value starts from zero.

Normal on our diesels. As for gasoline it does show idling flow rates.

Even my OBDLink LX doesn't show idle flow rates.

Well I have another question for you all. So I found an edge comp for sale on another forum and the owner and I are trying to determine if it will or will not work for my truck. Our build dates are almost the same (6/00 and 7/00) but he has the oval map plug and I have the round. He said I could switch out the sensors and splice a new end onto my engine wiring harness because they are the same voltage. However from reading around on other forums it sounds like edge has said that is incorrect, and that the sensors have different output voltages. While thinking about all this I remembered that my map sensor is connected to my engine wiring harness with flat blade connects. That made me wonder if my truck even has the correct map sensor or if someone else switched the sensors in the past. It's also possible the sensor harness just got damaged and had to be replaced of course. What do you all think? Would a newer map even fit in my truck? And if so would it run? Or run well? Edge also apparently says that at least their ez boxes are programmed differently for the different map sensors (not sure about their others) and that guys have used the wrong box and had it work but just not as well. So I'm trying to figure this out and make sure my truck even has the correct sensor... I also got an old style used EZ from a friend to test out. And it has the round plug so it will work with the way my truck currently is. But like I said since the connector is spliced, I want to make sure it has the correct sensor.

Wont work. 

 

The boost reading compared to voltage is Way different between the round and oval sensors.  The comp needs to be reprogrammed to work with the other sensor type.

 

00 trucks should have the round connector, who know when the actual 00 /01 switch was made thought.

Thanks for the reply! Do you think there is any chance my truck has the wrong one right now?

no, The wrong sensor would make your truck a dog.

 

I suppose you could flash the ecm with a later truck file, then rewrite everything to make the map work etc...but it is much more likely you have a 00 model and he has a 01 model.

Ok thanks again very much for the info. You have been very helpful as always. It wouldn't even be worth all that just to make this comp work. Plus I wouldn't want to risk messing my truck up. I was mainly concerned that my truck might have the wrong sensor.

There was at least 3 different MAP sensors that I know and the last two 2001 and 2002 can be interchanged.

Are those two both oval shaped then? Just one gray and one black?

yep both oval the 01 sensor is the commonly used one.  Typically if you buy a 02 sensor you actually get an 01 sensor with a pigtail.

Edited March 19, 20169 yr by Me78569

Interesting. So what's different about them then? Just color? Why do you need a pigtail if they are interchangeable? Sorry for all the questions, I just like to learn as much as I can about these trucks. Never know when the info will come in handy!

Really simple. The Pin Assignments on the sensors are different. Look at ground and signal assignments.

2001

• A. Org 5V
• B. Blk/Lt Blu Ground
• C. Gry/Red Signal

2002

• A. Org 5V
• B. Gry /Red Signal
• C. Blk/Lt Blu Ground

Oh ok that makes sense. Well thanks again guys. It's amazing much you all know about our trucks! 

Well after trying a 2003 Edge EZ from a friend I decided to order the Edge Comp. The EZ was not quite as nice as the smarty on the low end. Anyway, this morning I was thinking and I realized that between the Comp and my injectors I would potentially be exceeding my clutch rating....should I be worried about this? I mean I don't have to tap the pump, but I figured I might as well, especially if thats how I can get the best fuel economy. Anyway my clutch is a new Valair single disc organic rated at 400hp and 900ft lbs. I have 75hp injectors and the Comp I believe is rated at up to 120hp and 350ft lbs. I have no idea how to calculate hp and torque and how accurate it would be, but just adding up those numbers on paper and estimating about 150ft lbs for the injectors puts me over the clutch...what do you all think? should I just stick with the EZ? or will my actual numbers be lower than that? I don't think I want to just say ill drive it nicely because I'm pretty sure thats gona happen 100% of the time lol although I should add that my definition of being hard on a vehicle is way less hard on in that what most people think. I baby my stuff haha. I don't do burn outs or boosted launches. Just accelerate a little hard once things are at least halfway warmed up. And at that point I also rev it out a little farther as it 2500 at most. I should also add that my truck is about to hit 260,000 and I don't want to be too hard on it. I'm counting on it to last till at least 400,000 maybe 5....so just give me some opinions. Is an edge comp going to put undue strain on things? Particular my new clutch. Should I just stick with the EZ? 

Edited March 22, 20169 yr by leathermaneod

You fine on the clutch. I'm running just behind you slightly at +50HP injectors and wire tapped on the Edge Comp. I tow heavy and never had a problem with my clutch which happens to be a Southbend Con OFE. It's never slipped.

This all depends on your tire size. Oversize tires will put more stress on the clutch than stoc k size will. I'm designed to break the tires loose when I start reaching the threshold of the clutch so no damage occurs.
