Emira JB4 Tuning Now Available for I4 & V6 Cars!

[seriously]

We’re all just brainstorming out loud here. I would personally be concerned with water and debris ingress from the bottom. There is already forced air from one of the intakes. I assume better venting from the rear hood would be hugely beneficial. There is already good venting out of the rear.

 

[Tracked Emira]

yes and the Emira essentially is a closed system. it doesn't have enough venting topside when hot. which is why we all want louvered hatch glass.

JUBU vented louvre already solves this problem after you remove the rear windshield

Not sure about the look of that. I kind of like the smooth lines the rear screen provides. Could take a bit of time to like it, then I’ll probably love it. I’ll give it time for now. But I do see the benefits it would provide.

A Louvre like this would require a rear wing to complete its look. Without a wing, probably a poly glass with vented hole like the Ford GT40 could look quite good. I’m not too worried about water. These engines are fairly waterproof. My Ex 410 got loads of water in the engine bay with no problems at all. Could be wrong though.

Does this come with a rear view camera like the 812 comp?

Yeah everything is gasketed and sealed idk everyone is so up in arms about water.

No

Planning to get our shop car on the dyno soon. We will post some video and results to see what the difference in HP is between the maps.
We dont have 93 octane here so I have to make a trip to get some fuel to properly test it.

I would love to see what happens on a map 3 dyno run with the lower 91 or 92 octane rating. Just a slight reduction in power, or something more dramatic with the overall power/torque curve?

…… uhh knock knock?

The carbon looks cool but some want to be able to see out the back and into the engine bay still so we are trying to do a clear replacement instead.

@GRP Any news on JB4 shipments? My order with you is now sitting at 30 days and counting.

Waiting on Burger to get us more still. They had indicated we would have them last week but it didn’t happen, hoping for this week now. We have emailed for an update again today as well.
You are #1 on the list right now so you have waited the longest of anyone with a pending order, sorry.

Jeeze..30 days. I hope they give you an extra quick one for all your patience.

Yeah, certainly the concern, but Burger said they would want “additional testing” to determine if that happened (specifically using 92 vs 93). In most cars the ecu would limit power slightly on lower octane to prevent knocking, but not sure if that’s the case with a tune.

Burger isn't a tune though. That's the issue. All they have done is "fib" about select sensor input to the ECU. The ECU is doing all the rest of the work.

I think from Burgers perspective it's "ok" to run on more aggressive maps even if you don't have the fuel type to support it because the engine will still be doing all the factory engine protections. But, in practice that means the engine will experience knock events until the point which the ECU intervenes. Likely by pulling timing advance until knock events stop, or by dumping in fuel, or both. (Fuel will push the engine out of optimal power but ensures the engine isn't leaning out and causing too much heat which will increase pre-det.)

 

[Lotusdoesit]

28 days and counting for me. Something seems amiss here. If none were shipped last week, wondering if Burger hit the pause button to make some updates/improvements before sending out additional batches? Perhaps our friends here from Burger can provide some transparency?

With the irony being I live a few miles from Burger however because of CARB rules, product has to be shipped to Nevada only to be shipped back to me in CA.

Has anyone done a 3rd party dyno with the JB4?

 

[Payam@BMS]

Ran out of long OBD's so we're just waiting for them to come in from our supplier. They should be in any day now and the orders will be shipped to Greg for disbursement. Thank you all for your support and patience.

Even some “dragy” back to back runs, same day, same road etc, comparing the different maps would be interesting

 

[Tomwa]

I feel like Draggy runs is going to be such a bad way to identify the improvements. It's so highly variable on driver, conditions, etc. Are you really going to be satisfied with seeing a 0.2 second improvement on 0-60 when a completely stock 0-60 is variable within that range and beyond to begin with?
