They also immediately responded to me saying insufficient interest.

Not sure on engine temps, never saw over 200F on the dash, but I know that doesn't mean anything. I ran map 2 for one session just to see how it felt. I enjoyed it, but this is a small track and I actually wished it had a bit more engine braking. I ran map 1 for the rest of the day and as...

Ran the JB4 at my most recent track day and loved it! I just ran mixed 91/100 to ~93 octane all day just to be safe with the temps.

In my opinion: corner balancing is a highly unnecessary activity for 90% of track day drivers. It only really matters for racecar levels of suspensions stiffness. On a softer sprung car, the settling of the suspension is enough to counteract really small differences in corner weighting. On a...

I very much agree with Mike. Adding front camber will increase overall front grip, but at the limits of camber adjustment you will need to sacrifice some caster. If you are hunting steering weight, I don't think you will want to reduce the caster. You will also probably want zero toe up...

Mine is the 5th car from the right in the first pic

I'm in my Seneca just about every weekend. See you on the mountain sometime!

I absolutely love it. It is the new norm for me. I've switched back to 91 since I don't want to mix 91/100 in perpetuity. I miss the violence of map 2 but am still very happy

I think the seat is incredibly comfortable and I've done multi thousand mile trips in them. I had the seat for 4 weeks before the pads came in. For me. They might have been more comfortable before the pads, but you would slide around a little bit

I don't think it is so much making a "better tune", as much as it would be individualized services for making the tune work better on your particular car. In which case it always has to be an individual pursuing tuning at extra cost with Burger.

Yeah, definitely your ambient 114f temperatures and type of fuel you have access to is limiting the fun. Hopefully you get to try it in cooler months as well. My friends and I do lots of car swapping, and people were shocked at how much more power it had. I back to backed it with a Spyder RS...

As a reminder, the absolute value of different dynos cannot be compared to each other, nor can runs from different ambient conditions or days. This is the reason it is so important to do back to back. Your baseline number cannot be compared to this number whatsoever. Only differentials from...

Seems like there's some confusion, so compiling it all here (from posts from @sendmeows and @kitkat, I don't have any insider info). Setup Details: Car Details: valve controller, no other modifications. Ambient temp: around 85 deg Dyno Details: hub dyno, all figures taken same day in same...

His before and after are from different days with different conditions

We don't really know for sure because the dynos are taken on different days months apart with different ambient conditions. This is not meant to be a knock, I'm very thankful that he went ahead and got dynos. I'm just saying you can't compare them to each other

Yeah I gave up when every inquiry took weeks to respond to.

I appreciate that you believe there's some sort of learning going on over time. I'm not totally sure how that would work with the fact that people go in and get tunes on the dyno, and the idea is that they are leaving with a map that is fully functional. Maybe there are some tiny things still...

Cool, thanks for doing it. Good to know your butt dyno says positive things. I wouldn't put too much weight into the numbers on different conditions on different days. But, it is probably a bit less than 60 hp.

Ah ok. I understand that it's your money and we are thankful regardless. But same dyno, same conditions, same day would be the gold standard for allowing a comparison.

Thanks for doing it! You're going to get a run for Map 0 (disabled) and map 1?

Can you post/show a before/after JB4 map done by a 3rd party that clearly gives the before/after? I think people are trying to do it because there hasn't been much customer verified data. I say this as a very happy jb4 owner.

Oh yeah, to be clear I didn't remove the intake either. Just need to pry the clam open large enough. But doing that will probably split the bottom of the hinge which is the pain. Picture is just to be able to visualize what the bottom of the hinge looks like.

If you were able to get it to go in that way, awesome! When I tried prying the clam far enough to replace the filter, the bottom hook of the clam came undone. And reassembling that took most of the time.

I heard a lot of people say this was pretty easy. And while not that complicated, I didn't have a super easy time. I didn't see any instructions out there, so here it is. Some smaller people seem to be doing all this work while sitting in the trunk or on top of the supercharger. I don't really...

I'm an idiot 🤦‍♂️ Of course this meant like "fishing through a wall", not like literally fishing for fish LOL. Thanks!

Excuse my ignorance not being a Fisher. Something like the red line you have doesn't show up when I search fishing wire. Is there a different name for it? I seem to be seeing fishing line.

Not sure I buy this.

Several folks are interested in running JB4 without the OBD2 connection that has to be routed through the firewall. Is it safe to do so?

Installed the new buttons today. Some steps that helped me: Disconnect battery The spring clips for the airbag - they push inwards towards the steering wheel center axis (not fore or aft relative to car body). I used a thicker punch tool to lightly push inwards. You can feel it acting like a...

I love my piloti shoes of various kinds. They have several leather options.

Just fyi, I have the same things happen but I was just able to handle it with my expander. But definitely even though you would think that the slit stock pipe would clamp firmly, the hose clamp that is welded to it runs out of range, and so it stays loose. Better that you got it sorted.

I had this issue as well. Recently went to dealer and had them perform the various SW updates. It didn't happen in 1.5 hrs of use since (and used to happen a lot), but we'll have to wait to see for sure.

How do you reach the bleeder? I've heard people sit in the trunk, but i weight ~230-240lbs and am not sure I want to do that.

I'll be there in my Seneca V6

My full tank says like 150 range lol

2007 C6 Corvette 2019 GT350 2023 GR86 Only had significant track time on the GT350 and GR86. I agree that Lotus know what they are doing! Just remember that they are trying to find a one size fits all solution trying to fit the lowest common denominator of their users. I don't have a huge ego...
