Integrated Engineering Stage 1 Tune Install
Got it flashed today! Wasn't sure it was going to happen because I work up to this:
That's all new snow from overnight. Started out as rain, so the top was somewhat powder but the bottom layers were super wet and heavy.
Spent 3 hours clearing the sidewalks, patio, and driveway, and raking the roof. A couple of SUVs were getting stuck near me and our neighborhood streets hadn't been plowed right away so I was unsure if I'd be able to drive to my parents to borrow their laptop. I planned to do the flash at their house since the IE Flash Wizard software needs Windows and I'm a strictly MacOS household
Got to my folks and hooked up the battery charger.
To make sure the battery doesn't die while the ECU is being written... which would brick the ECU.
Got the PowerLink cable drivers and Flash Wizard software installed on my parents' laptop. Plugged everything in, detected my car VIN and when it came time to pick a tune, instead of the files I was expecting I got this:
It was saying it needed to "update" my ECU in order to do the main tune. No idea what that's about, but I go ahead and do it. IE has a weird "credits" system where they load "credits" to your PowerLink cable, and you pay for the tune with credits. Well, my credits were there, but this pre-update was going to use 1 credit, and I was worried then I wouldn't have enough to flash the actual stage 1.
I went ahead with it anyways. It acted like it was starting to do some stuff, but when it got to the progress bar, it stayed at 0%, and after a few minutes gave me an error message.
Kind of freaking out a little, both that the word "response" was spelled wrong and that my ECU might be screwed. I clicked ok, and instead of doing some recovery process it just took me back to the main screen. So I tried again.
Same error.
So I closed the app, unplugged everything, started from scratch. Now it says my PowerLink cable is not registered to anyone (I did this previously), so I do that again. It still wants me to do the ECU update, but this time it says 0 credits instead of 1 credit. Hmmm.
I try again and same error message. But when it goes back to the main screen now it can no longer detect my ECU / VIN / Transmission and throws me another error:
I won't lie, I was started to get frustrated and worried that my ECU was broken and I shouldn't drive the car.
I unplugged everything again, and this time switched USB ports on the laptop for the PowerLink. Restart the Flash Wizard. Try again.
This time... it works! Maybe it was the USB port? I don't know but watching the progress bar slowly climb was stressful. After about 10min, it finished successfully. Back to the main menu and now it shows me all the tune options for my car:
I chose the 91 Octane Low Torque file. I actually run 93 gas, I don't know why I picked 91. Maybe just to be more conservative to start out. I also thought maybe it would give some headroom to hit targets, reduce chance of knock etc, but I don't know that the difference between 91 and 93 even matters much.
20min of erasing and writing...
So a little bumpy but in the end it worked.
Now on paper I should have 299 hp and 346 lb-ft at the crank.
Funny enough they release their mobile app flash tool in 2 days, so from now on I'll probably use that.
As for the tune itself, I need to drive it more to give a full review but I'll just say a few things for now.
— start up and pulling away at low speeds is identical to stock
— it seems pretty smooth and refined, dare I say smoother than stock with how it revs
— it seems like rev hang has been reduced
— I can feel the extra torque in 1st and 2nd gear at city street speeds, but it's not insane or anything
— It's very drivable. I don't know what I was expecting, but it's easy to stay out of boost and pretty much drive like stock
— once boost is built up, it pulls a lot harder, especially in 2nd and 3rd. I only punched it when above 3k rpms, but I was able to spin the tires in 2nd @ 35-40 mph and in 3rd @ 40-50mph. Traction control came on. I only got to do this a few times because of road conditions and traffic. But 1 or 2 of the throttle punches were like holy $h!t!!!! Like throw you back into your seat. To get to that point, I feel like you need to have the accelerator pressed most of the way and be full boost. Outside of that, it's more of a marginal increase over stock. I guess what I'm saying is it's not like there's so much power the throttle is touchy and overwhelming... you still have to work for it. It's more like it's there if you need it. But holy **** it's quick at speed when you mash the pedal. I can't imagine what the high torque is like.
Overall I think this is exactly what I wanted. Super livable and mild around town, but exciting on the occasional pull. I'm looking forward to driving it more, especially once I get my summers back on and all this white stuff melts.
Thanks for reading
