Visconti Tuning Stage 1 Tester #3 (I think)

[brichard0625]

nice thats still a great number considering that driving habits from the data provided. Feels good to know that we can go crazy when we want and not have to suffer at the pump.

Interesting (= - no idea their shop was so close, only a hair over half an hr away from me. Wish I could have tested it since I'm going to Indy Thursday. I guess it would be a good comparison vs stock since it will be completely highway miles.

Here's a half tank update. I may be going to an Autocross tomorrow in Harrisburg so that will mess up the mileage of this tank.

Top speed of 79mph but it wasn't via hard acceleration like the previous tank.



Max RPM of 5151.



I seemed to have gotten a lot more red lights this tank so it shows through the distance and time in the different gears. It also reflects in the time in neutral as well from sitting at red lights.




The last two days have had cooler temps at night which is shown by these two pics from when I got back to my house and stopped in the driveway.




This shows 30 mpg and the trip computer in the car shows 31.1 FWIW.



Here's the mileage on the trip meter. It shows slightly less than what the mileage shows in Dash Command in the pic above. The discrepancy comes from the app shutting down when I receive a call and the bluetooth picks up. I made the mistake of logging this with my iPhone instead of my iPad. Next tank, I will log it with my iPad so it should be very close.



I am thinking about filling up before I go to the AutoX tomorrow because it will affect the mileage severely I think. I don't really care if having a full tank means extra weight because I am not going to win, but just to have fun and learn the characteristics of the car.

I filled up today and the mileage came out to be 27.97MPG. I had 300.6 miles on the trip meter and purchased 10.747 gallons. Here are some pics of Dash Command that show some stats/data.

BTW, I never made it to the AutoX. I'll get to one sooner or later.

Here's the trip meter and my receipt.



Here's the AVG MPG according to the dash computer.



Here's the MPG estimate from Dash Command.



The average speed of 35mph shows that i was in more traffic and spent some time at red lights. This will show even more a few pics down when you see the time in neutral & idle times.



Max RPM of 5151. I wasn't as "spirited" this tank.



Here you can see that I traveled longer distances in the lower gears than the previous tank.



Here you can see that I spent more time in the lower gears as well compared to the previous tank. When you use data from this picture and the previous, it shows that I traveled a distance of 10.9 miles in neutral and spent 52+ minutes in neutral as well.

I filled up again today and the car had 307.7 miles on the trip meter and took 11.407 gallons of gas. This calculates to 26.97 mpg. you can see from the data provided below from Dash Command, I didn't baby it this tank either. You can also see the inconsistency of the MPG computer in the car versus DC versus actual math. Since I started this test, I've been getting gas at the same Shell station and even from the same pump

Here the app shows 26.6mpg which is close to what the math says.



This shot shows that there was about 21.4 miles that were not tracked by Dash Command in comparison to the trip meter in the car. This is due to receiving calls while driving and the app disconnecting while the phone call was taking place. It also shows top speed of 102mph so I had some fun this tank.



Here it shows the max RPM of 7752 so I just about hit the rev limiter of the tune which is set at 7800RPM.



Here it shows the percentage of distance traveled in each gear.



Here it shows the percentage of time spent in each gear.



For those wondering what the car idles at with the tune, here's a pic of Dash Command reading the idle at around 800 RPM and NO IDLE DIP since the tune!



Here's the receipt and the mileage on the trip meter.



Here's the computer's calculated MPG, which isn't accurate but I took the picture to show it.



I have an SRT exhaust on order and it should be shipping very soon. (Looking to get tracking info tomorrow on it.) I plan on getting the car dyno'd before and after to see what type of gains I get. I was also thinking of getting dynos done with and without the Perrin pulley to see if there are any changes to put that debate to rest. Worst case I want to dyno with pulley and tune as baseline and then with SRT exhaust.

I'll have to mess around and see if I can get some videos of 0-60 times. I'll have to see if I can drive and hold my video camera at the same time and find a safe spot to do it.

Nobody seems to notice something wrong, so i will ask what's up with those hp and torque numbers they don't seem acurate?

What? You mean I don't have 242lb-ft of TQ?!?

There are some parameters in the app that I don't have set because, honestly, I was too lazy to find them out. Wheel circumference, frontal area, tire rolling resistance are some of them.

I am mainly using the app to record speeds, RPM's, temps and some other stuff. I didn't really think it would accurately measure HP and TQ so I didn't bother trying to find out the missing info.

My SRT exhaust just came in today and I want to get it dyno'd before and after the install to get actual numbers. Since I have tomorrow off, I don't know if I'll be able to wait to get to a dyno to install it and may do it in my driveway or go to a friends house and install it there.

Not to hijack the thread, but I picked up one of those U0073 faults this morning. I was running Torque (one of the first times I have) talking to a cheap ELM327 adapter (been in place less than a week.) I don't THINK I bumped it but it's not impossible. I cleared the code and it seems OK... does this sound about right? Should I be concerned?

Considering that my dealer is 45 minutes away, I'd prefer not to make a special trip there if I don't have to!

FWIW, I get 29.9-30.1 mpg with reasonable driving and occasional full-throttle bursts to redline.

[ruskymx]

I've gotten that U0073 code a couple times and it's usually when I bump the adapter or remove it and re-install. From what I read online, there is no reason to worry about it.

Hey guys just wanted to say thanks to John for meeting up with me last night we did the tune and holy shit I can say quite a difference. It was pouring pretty hard last night so I didnt get a real chance to play with it too much but I can tell you the idle issue I had is gone and the car and just wants to keep pulling. Fuel mileage Im sure will improve but that will take some time and patience of my right foot staying out of it. Anyone who is buying parts left and right should truly consider this upgrade, I'm a retard and bought all sorts of shit intake, exhaust, crank pulley and with this upgrade I feel as if I am getting maximum performance out of all the parts. If you love your car like I do look into this, I will followup with more information soon.

OK, cool, thanks. I thought so but this was the only mention I could find specific to our cars.

I finished another tank and this one had some lead-footed driving because I received my SRT exhaust and installed it. The trip meter had 175.3 miles on it and it took 7.126 gallons which is 24.6 MPG. The dash showed 26.7 MPG and the app showed 24.8 MPG.

It wasn't a full tank because I was leaving for a trip to MD so I didn't want to have to worry about stopping for gas part way so I filled up. I'm almost through another tank from the trip so that will be my last recorded tank for this thread. I still log it all the time, but won't post in here.

Here are some pics:

Looks like the exhaust cut a little bit of the mpg but its only like 1.5mpg..plus u said u had lead foot this trip lol..im sure ur enjoying the extra power tho lol

I think the drop in MPG is from the time running the car when it was stationary and doing the videos I took of the exhaust. Plus, I was giving the "happy" pedal a workout.

I'm very tempted to get the E85 tune from John when all the GB participants orders have been completed and ECUtek has enough cables. I found an E85 pump within 15 minutes of my work.
