Switched to EFILive!!

[MChrist]

Well, I was always curious what my truck made on the dyno. . 400-500 was my guess. A place near me has a huge dyno that can load the truck down and they can hook up their computer to see what my Smarty is doing. Maybe I was tuned correctly, maybe I was way off. . no way for me to really know.

Turns out, my truck makes 456hp/956tq.

So I asked about their EFILive tuning, and turns out they have a tuner that is made to work with my exact setup. They could remove the Smarty and install their Spade tuner (King Version) and run it again on the dyno for a direct comparison. Hmmmm... And it would only take 30 minutes... hmmmmmmmmm.

30 minutes later, she's back on the dyno. This time, making 535hp/1078tq!!

The numbers don't tell the whole story, though. She builds boost so quickly now, it's shocking. I'll definitely have to turn it way down for winter.

Boost went from 42-44 before, to around 46-48 now. Where Smarty power peaked at 2600 rpm and dropped about 45hp in a straight line to 3200 rpm, this tuner has a 50 hp advantage from 2200 rpm up to where Smarty peaked at 2600, then the power advantage continues to grow to a max difference of over 100 hp, holding roughly 100 hp more from 2800 to 3200.

While that's all impressive enough, it's the part throttle response while driving that's making me post this. I had a 900lb tank in my bed, and the truck felt like a sports car.

My truck made very little smoke before, and makes no more now with the extra power. Maybe a very little bit more at full throttle and high rpm loaded on the dyno. I took video to compare.

Overall, I'm very impressed. I understand Smarty has a version similar to EFILive, but I was feeling frisky and wanted something new. Boy, I got it!!

They also ran the truck on the dyno with Smarty removed and factory tune... 313/575. Not bad!!

I'll keep you guys posted with any new developments, good and bad. Mpg comparisons, EGT differences, etc.

I have the dyno sheet showing my truck with EFILive tuning, smarty S-06 tuning, and with no tuner. I'll try to get my wife to post it, since she is the tech person in this house.

Awesome! Can't wait till it comes out for the 03-05 trucks

Good deal, I am interested in your results.

What you are experiencing is similar to what UDC can do.

What settings were you running before?

Do you monitor drive pressure?

It seems I was running SW9 @75 for the past 2 years. Last month, I bumped it to 99.
All the other settings were confusing to me, so I can't tell you for sure where they were. I changed things around and found a setting that was a bit softer at tip in, and didn't smoke as much. May have been torque management, may have been timing, may have been both. . after two or three years of having it, I was still unclear what I was doing. That's why I didn't feel qualified to do my own tuning with UDC.
I probably should be monitoring drive pressure. I've read your posts regarding it and I just haven't gotten around to it. When I blow a head gasket, and my truck is down, I'll find the time to fabricate it up...
One other thing I've noticed is my EGT in drive standing still used to be 450. Now, it's closer to 300. Also, when I go to park my truck, I would have to wait at least 20 seconds to get EGT below 400. Now it's below 400 as I put it in park. I'm thinking it's due to a combination of timing and duration. That's my limit as far as programming...
When I have any updates, I'll keep you posted.
Thanks

With your power dropping fast at 2600 rpms I would guess the PoD was still at 75, as that is how/where PoD 75 would effect power.

 

[Jim W]

I would turn down the power a little. I know my son who is using EFI Live melted a piston on his truck over fueled and had to replace his second transmission, now on his third transmission.

He has a 06, 2500, 5. 9 auto Crew Cab Long Bed, 4X4.

We plugged Smarty in while still on the dyno, and it said 99. Dyno operator also said that's a typical "Smarty curve". Sees it all the time. Unless I'm feeling frisky, I'm never over 2600 rpm anyway, it's everything under 2600 that has been so impressive to me. I haven't looked at EGT at full throttle yet, but there is a hill that I drive up every day going to work. Fairly steep, fairly long, I set my cruise at 60 and egt will always be 685 in winter, 700 in summer. Yesterday was 70 outside and 700 EGT, so no real change there. I'll probably burn through this fuel tank by next week, and should have mpg numbers for you.
I do know that the last setting I made on Smarty with TM or TQ softened up the response at tip in, and didn't smoke as much from a stop. Since all my miles are stop and go, short trips, and usually loaded by pulling trailers or having 1500 lbs in bed or both, my previous 5-6 tanks gave me 12. 2-12. 6 mpg hand calc. Since I softened up the Smarty setting, 3 consecutive tanks were 13. 4-13. 6. Apples to apples driving.
This Spade programmer I have now has 5 preset tunes I can download. There is a "max effort" setting, heavy tow setting, light tow setting, sport economy setting and something else. After this tank is gone, I'll switch to a much less aggressive setting. This place also ran my truck on the sport/Eco setting, so I'll see if they have the dyno sheet on that.

Yeah, but mine is a short bed, so I'm not worried...
I know what you mean. My trans is the heavy duty version from Goerend, so that should handle the power. As far as melting a piston, did he do his own programming? Seems easy to get carried away with "more is better" on these things. That's why I'll stick with their tunes. They don't want anybody blowing up stuff either.
Thanks, though.

Gotcha, it could be that SW9 was too much fuel for your CP3 and SW7 could have easily netted more hp.

One thing about UDC, over box Smraty tunes, is that we are able to fuel much harder and not drain the rail based on the fueling map. The box tunes drain the rail at less fuel just based on how they are written. That's the same concept as EFI Live and why they were able to make more power on the same setup.

 

[MChrist]

My CP3 was replaced with a unit from Floor It Diesel. Several years ago, pulling out of my driveway, truck just shut down. Apparently the shaft in it sheared off. The new CP3 flows either 33% or 50% more than stock, and also has a bored out rail, so my fuel pressure at the rail is very consistent. Even at peak power, my rail pressure was still around 22K.
Not saying you're wrong, since you know way more about this stuff than I do, just telling you what I got.
It's all voodoo to me...

 

[AH64ID]

Do you recall what RP setting you were on?

OEM peak is 23K.

I usually had the RP on stock, which on my digital monitor indicated 23,280. Last week I bumped it up to the next level on Smarty and I THINK it would hit 24-something. I just took it out for a ride now (efilive) with the RP setting showing, and it would hit 24-something right after a shift, and high 23s the rest of the time.
Another thing I noticed is RP at idle in neutral. It was always 6800-7000, now it's 7600-7850. My EGTs are slightly higher when flooring it. I just hit 1300, which before I had a hard time hitting 1200.

I noticed I mistyped in my last post. I meant to say 23k, not 22. .
I better switch to a lower setting before I blow a head gasket or an injector tip, huh?

So My Pump was replace With Johns?

Hey Todd! The new CP3 from a couple years ago was sent from you as well as the different rail. If memory serves, the box it came in said "floor it diesel". At least that's the name that comes to mind. My apologies if I'm mistaken. If the pump was yours, do you happen to know what percent over stock flow it is rated for?
Thanks!

 

[TCDiesel]

It was a Stage 1,We NO longer use percentages , the more Accurate ratings are HP STG 1 600HP, Mild 700HP, Wild 750HP, after that stoke pumps 800hp. Duals 1000hp.

 

[MChrist]

Thanks Todd. Do you think I should upgrade my lift pump situation yet? It's 100% stock, never touched, and I'm right at 100,000 miles. If its time to upgrade, I'd like it to be quiet. I've seen videos of aftermarket lift pumps whining away, and there must be a quieter solution.
I predict newer injectors, valve springs, studs and gasket in my near future... may as well do it before something blows...

 

[rscurtis]

I have a Fass 95 on my signature truck which I installed shortly after I bought it, and it was noisy. Lowering the fuel pressure spring made it significantly quieter. However, when at the Carlisle truck nationals this August, a Fass dealer had one of their new pumps running and it was absolutely silent. You could mount it in the cab and you wouldn't hear it.

if you are running a stock lift pump, i would have upgraded a long time ago with the power you are running at. stock lift pump can't even keep up with mild box tuners. .

 

[MChrist]

So how does a person determine if a different lift pump setup is needed? And which one to go with?

 

[Regcabguy]

My stocker works well with wot Smarty on sw #5. Seems I'm always reading about an aftermarket pump failing and a week wait for a replacement. Serviceability is sure superior with an aftermarket.
