So I live in an apartment complex currently, and I bought a tune for my audi Q5. I also just bought a battery charger since I don’t want to risk messing up my ECU.
I for some reason figured I’d be able to charge the battery charger, unplug it after some time, then just use it portably. I was wrong. It needs to be plugged in to use.
So if you were in my shoes, where would you flash your ECU? Are there known places that have power outlets near places to park?
I would just go somewhere like an auto parts store, a place where the employees are likely into cars. Buy something, regular maintenance items or otherwise, and just ask them if you can use an outlet. Most places will have outlets outside. Hopefully they’re cool with it then just do your thing outside the store.
Tune a Q5? Might as well of just gotten an SQ5. The difference between a Q/SQ5 is not just hp.
I also just bought a battery charger since I don’t want to risk messing up my ECU.
Can you explain your reasoning behind this?
If your voltage drops too low while flashing your ecu you can fuck it up - same idea as turning your computer off in the middle of writing data. Wherever you’re writing data can become corrupt
What’s actually recommended is a 12v power source, not a battery charger. Two different things… Charge your brand new battery in your apartment and you’ll be fine to flash. Obviously, disable all your accessories.
IE themselves reccomend a 10A minimum battery charger, not a voltage source (though I’m sure a stable voltage source would work as well). I’m just going with what they recommend.
The main power draw when flashing with the IE tune at least is the fans that come on, apparently. I’d have to remove the corresponding fuse. Could do that, or plug in the battery charger
you need to have your battery on a trickle charger to flash a tune?
I’m out of the loop since I’m running aftermarket ecu on a pre obd2 car … it doesn’t have such a requirement
It’s recommended since it can take some time to flash the ECU, and if the battery drops too low in that time you sit with the ignition on, but not running, it can brick the ECU.
A buddy of mine who does a lot of camping has a portable solar generator thing that might be feasible… not sure which one he had but something like this https://www.walmart.com/ip/PECRON-E600LFP-614Wh-1200W-Portable-Power-Station-Solar-Generator-LiFePO4-Battery-for-Camping-RV-Home-Backup-Outdoor-Emergency/1304938986?wmlspartner=wlpa&selectedSellerId=101132533&gclsrc=aw.ds&&adid=222222222271304938986_101132533_150868523029_20369052668&wl0=&wl1=g&wl2=c&wl3=665693022399&wl4=pla-1964598910726&wl5=9057544&wl6=&wl7=&wl8=&wl9=pla&wl10=551716940&wl11=online&wl12=1304938986_101132533&veh=sem&gad_source=1&gclid=CjwKCAiAu9yqBhBmEiwAHTx5pzwScVrkR8W8s1q0EdkfoeQ1MV4ImKMSAAgSee2bpxYtqxeu-0pLNBoCGEoQAvD_BwE might work

You were thinking of a jump pack. Something like this: https://www.amazon.com/AVAPOW-Battery-Portable-23800mAh-Vehicles/dp/B08NPHZV8N/ref=sr_1_6?crid=3S4OQ1RHDHTLI

When camping I’ve seen small, portable generators that were actually solar, had a few outlets BUT is your parking area secure enough where you could use it and not have it ripped off?
If I were in your shoes i’d ask for a refund on that tune XD
Adding power is done by upping boost, which puts more stress on everything. This is an SUV, not a race car, is it worth risking your expensive turbo and clutch ?
Not to mention the tune will be erased if the car is ever updated by audi, which it will during maintenance.
Car doesn’t have a turbo BTW. I also don’t plan on ever bringing it to a dealership, I’ve got a really good mechanic close by
Wait….
So you just paid probably $500 to tune a naturally aspirated car?
That is the biggest single waste of money on a car unless you have supporting mods (injectors, forced induction, nos, maybe exhaust, etc).
A naturally aspirated tune will get you, what, 25 horsepower?
They got you good.
Lol not even 25, plus it will reduce drivability and reliability. He’ll learn one way or another
You know nothing of the engine or tune I’m going with, apparently
You are making a ton of assumptions.
First off - my car is supercharged. It’s the 3.0t, not naturally aspirated.
Secondly, where are you getting pricing from?
Thirdly - it’s good for a 140hp increase. The 3.0t supercharged used in many audio has tunes from several different vendors that are capable of 400+ hp. IE, the one I went with, is 415
A buddy flashed his older Audi sedan to raise boost, and the resulting carnage was epic. It blew every piece of charge piping off the car, one at a time. Then, the clutch went. Then, the transmission. Then, a turbo.
Do you have a friend that has a garage? Maybe an extension cord from your apartment?
Your apartment complex might have rules against working on your vehicle in the parking lot. Be careful.
True, I’ll look into my lease before attempting. Good thinking
