These dyno results were posted from a JUBU ECU installation by a forum member earlier in this thread. JUBU limits torque (Below 500nm) to preserve the pistons based upon their extensive experience with the motor but there is some risk any time you tune. It certainly appears that they delver what they promise (and then some).I really do want to try this, however I'm having a hard time validating the effectiveness of this ECU swap, and quantifying longevity of the powertrain after install. Is there info I'm missing, I only see a few basic videos online. Thx!
Right on, I've certainly have seen their short videos and posted dyno sheets, what I can't seem to find is a healthy amount of folks who have performed the ecu swap and offer their feedbackThese dyno results were posted from a JUBU ECU installation by a forum member earlier in this thread.

Really good summary! I’ll let others chime in with more experience but to answer one of your questions around smaller mods, yes, many already have these mods and seem fine with JUBU.I'll start out by apologizing with my following summary/questions and state that I've NEVER modified a vehicle before (other than a simple Solar throttle control on a 2023 C8 Corvette), so this is all new to me. Next, I'll sincerely thank hellasf1 for all his hard work/time/patience and initiating this Jubu group buy. I found your numerous comments invaluable. Perhaps (?) the following summary putting everything together in one posting will help others like me, who are new to the "modding game", and encourage more sales...
I'm interested in the Jubu ECU 440 HP upgrade. My understanding:
1. current price set to expire around the end of this month: 6,690 Euros; however for Forum group buy it's 5,409.16 Euros (w/o EU VAT, for non-EU buyers), less 15% discount = 4,597.79 Euros, plus ship and cross-border customs fee on top. An example of those latter 2 were US$220 ship and US$191 customs for hellasf1 in N. Carolina (no doubt varying for others elsewhere).
2. to achieve that HP increase frm 400 to 440, you need only the Jubu ECU which can later be used as a stepping stone for further HP increases (460 and up to 500 HP), for those who want to go the extra mile/$ and install additional engine mods, which carry a hefty cost for replacement parts and labour.
3. that said, some suggest it's really beneficial to marry the Jubu ECU with the third Cat delete and an after-market air filter such as those sold by GRP (Gregsraceparts.com):
a) Emira Cat Delete for US$249 (and to be safe, a new exhaust ring gasket for about US$10). Jubu mentions this third cat delete will add some 5 to 7 HP;
b) either the High-Flow Dry Media (oil-free) air filter for US$74.99, or the K&N (pre-oiled) air filter for US$64.99.
I note Lotus issued service bulletin 2020/01 focused on after-market air filters and telling all dealers these void warranties since they can cause issues, plus make no performance difference. No doubt the Jubu ECU would void warranty as well, IF left in when dropping the car off at a dealer.
Is everyone else who has the Jubu ECU, doing at least the above 2 smaller mods (third cat delete and "upgraded" air cleaner) or any others that don't cost a lot more dough?
4. After purchase steps necessary:
a) the ECU install time ranges from a low of about an hour (if the left rear wheel well is removed) to less than 15 minutes, if you know what you're doing and have the right tools, to do the swap all within the engine bay. Did you ever get a video hellasf1 of Rene doing the shorter engine bay install? If not, your explanation on this thread seems fairly clear.
b) remote tuning session with "Jubu/Syvecs", to properly calibrate the ECU software, by connecting the Jubu ECU to the Syvecs "TeamViewer" using a windows-based laptop. Sounds easy enough but it's troubling for me in Canada to see that my country looks to have had the majority of ECU software glitches, compared to all other countries although it sounds like Jubu has worked hard to rectify them for everyone.
5. other options available, with the Jubu ECU:
a) the main additional option I want is the increased speed limiter, from 6,800 RPM to 7,200 RPM. I don't see any pricing for this "option" and perhaps (?) it comes with the Jubu ECU n/c? I note Jubu recommends it be combined with their "cooling kit" (199 Euros, for both a new thermostat and water pump...with either a 76 degree thermostat for street and track, or a 69 degree thermostat for more frequent track use). And then, Jubu suggests the cooling kit would work best with a "charge cooling hose upgrade" (219 Euros). Finally, hellasf1 mentions a January software update for the speed limiter (and the +/- cruise control buttons), so it looks like everyone with this Jubu ECU will need at least that update, once it's announced by Jubu sometime early next year.
Is there an extra cost for the increased speed limiter? Did everyone get at least the Jubu "cooling kit" to go along with it?
b) the website mentions a BlueTooth modul (990 Euros installed). I'm not overly interested in accessing ECU data on my iPhone, etc. for my (mostly) street and occasional track use, but I'd be interested in hearing comments from others who think this worth the dough. I note hellasf1 has mentioned anyone who purchased the BlueTooth modul, will be getting a free upgrade once Jubu releases a better version, so apparently that's a work in progress.
c) the website also mentions a "Motorsport traction control GPS module in 12 steps" (1,690 Euros installed). I couldn't see an explanation of exactly what it is; the website reference went nowhere for me. Can anyone explain that and whether it's a worthwhile option for the price?
6. Finally and when selling your Emira, the "bad news" is that the Jubu ECU is tied to a specific vehicle VIN, but the "good news" is that you can remove it and sell the Jubu ECU to another Emira-only (likely?) owner, who can then have it reprogrammed in about an hour by Jubu, for about 150 Euros. So you should be able to recoup some of your cost for this mod, if the person buying your Emira isn't keen on paying for it (most buyers ignore the cost of any accessories).
Hopefully my summary is correct. I'd very much appreciate answers to the highlighted questions above and thank anyone who's been patient enough to read what I've just posted.
t does on track mode onlyDo we know if the Jubu upgrade gives auto rev match? I know I know heel and toe - but I must admit sometimes it's easier.
It is the same price 6800 or 7200rpm its up to your liking.Really good summary! I’ll let others chime in with more experience but to answer one of your questions around smaller mods, yes, many already have these mods and seem fine with JUBU.
I’m also curious on the speed limiter question as the 7200 redline would be ideal.
I wasn’t planning on getting anything outside of the JUBU ECU. No cooling,m extras, no Bluetooth etc. I was simply considering getting the ECU. (I wonder if it comes with a OBD2 plug that you connect to a laptop etc for those that don’t get Bluetooth).
Yes it does. Only in track mode and you must be on the brake to activate. Obviously no gear sensors in the transmission so this is the only way. They might created it for the transmission but that would be a big install just for you to have auto rev by clutch engagement only.Do we know if the Jubu upgrade gives auto rev match? I know I know heel and toe - but I must admit sometimes it's easier.
