Is EAP To FSD worth

notreallyayan | 2026-01-17 17:48 | 22 views

Just picked up a 2018 Model for a great deal that already has EAP on it. I’m a student so obviously having the extra cash is always good, but is the investment on EAP to FSD worth to avoid the sub pricing I plan on keeping the car for a long time and I’ve seen some talk about HW3 class actions and things needing to be done for HW3 owners. Also it is on HW 2.5 rn, I know there’s a cost of upgrading the computer if you’re doing sub pricing, so I probably wouldn’t do it at all What are your guys thoughts, should I just grab it right now before the lifetimes not available

Honestly would be worth it just for the HW upgrade anyways.

Dual hw3/hw4 household also. HW3 FSD is freaking amazing compared to anything else out there - except for hw4 fsd which feels truly sentient. If money is tight though I’d hold off. No idea of timing but Elon did say last year they’d build an upgrade path for hw3 cars - which would mean it would work with 2.5 cars too, as hw3 was a drop-in replacement to hw2.5 cars. On the question of timing - $100/month is a great deal, you need to go many years before buying makes more sense. I wouldn’t justify that on an older model, personally.

I thought Tesla wants $8,000 to upgrade the HW2.5 to HW3 with lifetime FSD. FSD cannot run on HW2.5. Not sure I would do it. If you want a car with lifetime FSD at some later date, you can always buy a used one with it. It goes with car. That's how I got lifetime FSD.

Nah it’s 2k.

My 2018 LR AWD (original owner) was purchased with HW2.5 on it but Tesla had upgraded mine at no cost. Too bad the original owner didn’t stick around long enough to get theirs done by Tesla. As I recall the upgrade included not only the HW3 board etc but updated cameras. I updated my EAP to FSD during Elon’s first offer at $2K. Didn’t use it, figured my husband might or I might when it got better. I still prefer to drive my car but my husband has been using FSD on my HW3 for a while now. It’s pretty good. You will still need to supervise. My husband upgraded his 2017 MS to a 2024 model and he has HW4 on it. He recently used the FSD trial on it and FSD has some very nice features I don’t get with my HW3 version and both of us are very impressed with its state presently. Many trips taken end to end with no driver action needed. I forget which car we were driving recently at night on the highway with FDS in a heavy rain storm, but we both were impressed with how well it did staying in the lane when we were kind of having trouble at times seeing the lane markings. You didn’t say what your upgrade cost is from HW2.5 to HW3 is. I waited a number of months back then for the parts to come in stock and had to take it to SVC to have everything installed. I am pretty happy with my car the way it is with HW3 and FSD. I also plan to keep it long term. Would be great if I could get HW4 on my car but doesn’t seem possible. We are happy with FSD and saw it improve over time. This version I’m on now is pretty good and I have no regrets upgrading. There are some nice advantages with EAP on HW3 so hope you can get a chance to see them in person. You might see if you can find someone with HW3 on their car and ride with them to see if that upgrade is worth it with cameras and such to you. Great if they also did the FSD on it. But you are correct you’ll need HW3 first to upgrade from EAP to FSD. Keep the end date for buying FSD (2/14) in mind. For my husband, he likes it and will buy it for his car since he plans to keep his car more than 2 years, which is the breaking even point.

If it's $2,000 I would probably do it unless you don't think you would never use it. I heard only about 12% are sold with FSD. Personally I like it a lot. It's not perfect but it takes a lot of stress out of driving. I just drove from the SF Bay area to Seattle and back, then to Portland and back. It's way more relaxing with FSD.

For $2k it is a no-brainer. Do it while you can.

notreallyayan 2026-01-17 19:58

Oh I didn’t know that the cameras get upgraded too that’s a huge plus! From EAP to FSD theyre asking 2.7k CAD or 2K USD, definitely think it’s worth then

LeaString 2026-01-17 20:49

Yeah we noticed a huge improvement in all cameras. Better resolution, color was improved, better night time imaging. If they’ll upgrade to FSD for 2K (I’m US) and that includes HW3 like they were doing for 2.5 owners back when they did mine, I’d say do it. I would think it might be all inclusive but don’t know. Definitely ask what would be included.

OP said his 2018 car already has EAP ($5K) on it. Back in 2018 adding FSD was an additional $3K (still have screen shots of Tesla order site from when I ordered), so Tesla wanted $8K total. We didn’t feel FSD was worth ordering then so just ordered EAP. I subsequently took advantage of Elon’s initial EAP to FSD special for $2K and my HW2.5 on car was updated to HW3 at no additional cost to me. The $2K upgrade price now (offered until 2/14) would bring it to $7K from Tesla’s standpoint. For OP to buy the car used with EAP, given how well FSD now works in my car, not a bad deal for all the improvements. He’d be locking it in with no future cost starting Year 3. Honestly who knows what Elon will do with future cars. He’s said you won’t be able to buy one to own at some point so sounds like he thinks everyone will just use a robocab or pay for a subscription to drive a car.

Do it. I just upgraded a 2018 3 with EAP. HW3 FSD is still incredibly capable and your option to upgrade is likely going away soon. HW3 will be included with the FSD upgrade.

Does anyone know if after the hw2.5 to 3 upgrade for FSD if EAP can still be activated (autopilot with lane changes) after upgrading to FSD and if so if cabin camera can still be covered for it?

ian799 2026-01-18 03:50

Do it. Just did the upgrade night and day diffrence from EAP way smoother.

MCKALISTAIR 2026-01-18 10:15

If the upgrade comes with FSD I’d say it’s a no brainier

SomegalInCa 2026-01-18 15:32

I had just the computer upgraded on my 2018 and it was $1000 2 years or so back. I lost my parking sensors to the new software version (downgrade I would say) but otherwise regular old EAP is fine for my use and the car gained some visualization it didn’t have before The FSD trials I had convinced me not to pay $ for FSD but now with subscriptions I could choose to use it on a longer trip if I really wanted For the most part using smart cruise is good enough for my needs and it works reliably enough Just another data point for you as a 2018 owner

lolitstrain21 2026-01-18 20:16

Yeah it does.

takeyourtime5000 2026-01-21 02:58

How did you get a camera upgrade? I have a 2018 m3p but didnt see any mention of a camera upgrade. Edit: Ahh. Model 3s dont need the camera upgrade just model s and x.

aimg 2026-01-27 17:17

The ultrasonic sensors were disabled with an update?!

SomegalInCa 2026-01-27 17:23

Yeah I believe it was the hardware 3 computer no longer looks at parking centers now I have a choice for as those yucky video parking stuff

TooLumpy 2026-02-11 23:35

I thought the ultra sonic sensors were still used, but the radar sensor was disabled. Are you noticing a difference in the on screen animation or distances? What choice do you now get?

SomegalInCa 2026-02-12 01:23

I only have vision as a choice with the FSD 3 computer it seems
