I've had a week to play with my SCT Livewire and noticed a few things I'd like to share with everyone...

I have the 7.3L PSD and found it funny that none of the distributors I spoke with could nail down what I was to expect for adjustable parameters, not to mention what PIDs I could see or how the canned tuning would be.

So, having had a week to use it I am a little disappointed with the canned tuning. I get overboost code (P0238) on pgms 2 and 3 (of the three included) as well as P1249. The packaging states that I am supposed to be able to clear the codes with the display. I can't. Not on the fly, not while stopped with the key on. It tells me the codes have been cleared, but clearly, the CE light still illuminates. I can only clear the codes by reflashing the PCM again with either the stock tune or the canned ones.

As far as the PIDs, I don't see EOT (engine oil temp) offered but it does have some sort of values displayed for ECT (engine coolant temp). I seriously doubt my engine coolant is at -12*F when I go to start it in the morning and then it just gets colder to -100*F after driving a while. So that PID is pretty useless. I wonder if they're working on that?

To use the other expensive features, I have to dial in huge values into the unit via the spinning wheel located on the front. For example, by single digits (1, 2, 3, 4, ....1350) I have to turn that wheel to set an alert for EGT. It's almost a 1/2 turn of the wheel for each digit. Forget about the estimated Tq and Hp calculations because of this. It requires that I dial that wheel to indicate my truck's weight at ~7955 lbs. One lb at a time.

So I guess my question, after the ranting is this. What did I get for $729?? I only have a CAI and Exhaust system. Surely that was supposed to aid in the canned programs right?

I sent back my Edge New Evolution because of their lack of action in similar ways. I've heard really good things about SCT's tech group. The distributor who I bought it from sent me right away to SCT's tech group. I called SCT for the first time today and haven't received a returned call yet.

In SCT's defense, I feel that the canned tunes are smoother in power delivery and shift parameters so much so that I haven't even altered the user selectable parameters at all. The speed limiter is gone by default and my mileage has gotten better despite the "Winter Additives" in our fine diesel I;ve purchased lately.

In the distributor's defense, he recomended that I turn everything back to stock and get my PCM reflashed by my local dealership. I am the third owner and so I have no idea as to what may still reside in the PCM's calibration. Can a Bullydog (or other) really leave something permanent in there, even after it's been returned to stock once again?

Does anyone else have a suggestion? Am I asking for too much?

[BTW, I don't have the DRV++ or the boost tube currently on it]

 

$729??????? I paid $539 from a place that tunes diesels and gas. You Won't read any inputs unless there is a hookup for it(wideband O2 or oil temp) and it goes in the analog input I believe. I haven't done much since I just got it today. I'm using the monitoring feature and all the parameters I'm monitoring are believable. I'm now thinking of getting the pro racer package for a more in depth tuning.

 

Yeah, it's about another $200 for the EGT sensor so that = $729.

Any Diesel owners out there? SCT's gas tunes and marketing is different.

 

Is that a sensor that must be used with their unit? We used to just put a stainless steel probe in and a reader. I hope they can use a Bosch 5 wire O2 sensor. I want to read A/F.

 

Why not save yourself a lot of money and get a DP-TUNER. I guess you never look in the 7.3 fourm. Come and talk to these guys, they are great and can answer any question you have about the tuners. Most ran another tuner/chip before the DP, I ran the Superchip for 4 years before I came on here. Now I have 3 times the power I had before.

 

I feel my dealer is skirting the answer i'm looking for also. I'm gonna put it back to stock then back to the 93 octane tune(till this tank of gas is gone) and see if I can get into the trans tunes.

 

Thanks for the feeback. I also wanted a digital display combined with a tuner so that's how I ended up looking at Edge and SCT. As I have some other issues with SCT's Livewire, I may end up looking at the DP stuff and going that route.

Thanks again!

 

I have the New Edge Evo and had no problems with it.

 

I found out what my problem is with mine. I got an email with nnew tunes and tried to download them an got an error message. The problem came from the factory and the engineers will be finding a solution. The dealer is treating me as I treated customers when I had a business. If need be we will swap units. I have his cell number also.

 

Okay, I think you're officially hijacking my thread. Please move on and start one of your own.

 

What's the 6637 mod and the KCM SSHPCL mod?

 

Sorry I didn't mean to but what should I call it?

 

Okay, it's been a week. Still no contact back from SCT. This is looking like another Edge experience.

 

6637 air filter mod, SSHPCL stainless steel high pressure cross over line

 

Ah, thanks for responding. What gains did you achieve with teh SSHPCL?
