Emira JB4 Tuning Now Available for I4 & V6 Cars!

[Kimmax]

I would love to see what happens on a map 3 dyno run with the lower 91 or 92 octane rating

…… uhh knock knock?

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

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.

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 "fiber" 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.)
