Nope.
I don’t know anybody in BMW circles.
I personally had O2 sensor failures early in the life of my Emira, which was a known problem.
The injector thing didn’t come from me, but I’ll ask the service writer about it next week when I take the car to the dealer. See if there is any concern.
Boy I would sure welcome that practice.....bring more enthusiasts into the fold without fear.....that said, it's all about margins here in the US so that's not going to happen.
My reacting was similar. By the way, a 90% non-failure rate sounds darn good to me., even if it were true. It would likely be much better than one could expect from most auto components, specially involving mods. Happy to live with those odds
Fair enough mate. What I’ve seen usually s when a manufacturer notices a common fault, they recall the whole fleet and correct the problem. 10 injector faults out of 50 known cars is a lot of faults.Nope.

From what I read, it appears that most USA owner will be selling their cars after the warranty expires. Maybe the dreams of a number of happy future owners of second hand emira will get their lifelong wet dreams of buying an emira for $20k. All brought to you by current doomsday owners. Do you get what I’m saying?
I do Sir.
My car is a long term ownership thing for me.
Other than the O2 sensor failures, my car has been bulletproof (knock on wood).
I love my Emira and although I don’t drive it as much as I would like it does bring a smile to my face when I get behind the wheel.
By any chance are you guys running gas above E10? Like E15, E20 or E85? That's a possible source of injector fouling.
No, it's not popular in China.
Today we have completed another round of test.. with side by side runs and eventually a solo run with a race box (see reports below). The Map2 basically operated as oem (map0), this was also evident on the last runs done and shared. The map1 being the only map that showed a slight difference. Hence we can conclude that map2 did not work (connected with the wire). The logs have been send to jb4 for analysis.
Run1 is map0
Run3 is x
Run4 Green is map1
Run5 is map2
Run1 is map0
Run3 is x
Run4 Green is map1
Run5 is map2

There is definitely something not right with those numbers.
I’ve done 0-100kmh in less than 5 seconds (recorded on dragy) in a totally stock car and with a laughably slow 1st to 2nd gear change (not to mention heaps of wheel spin at the start).
Others have recorded times under 4.5 seconds, and I have no doubt my stock car could do the same with a more aggressive launch and a better driver than me in the seat.
Have you had your car on a dyno to check it’s making the power it should be?
Mine showed 284 rwkW totally stock, which is in the ballpark of several others on here, and more than Lotus actually claim.

I have reported earlier that 0-100 with a massive clutch dump was around 5.6/5.8 seconds but recorded ballpark with the phone start/stop and not a draggy. The numbers I have above were without a clutch dump but rather a soft launch.
I have done a dyno once (see below) and that was with the jubu440. The numbers were promosing but yet again side by side runs with same mod emira except the performance upgrade.. the difference were neglectable.. hardly any difference which is odd because on paper the power was thwre. As of now the car does perform same with a same mod car.
Temps were today again 44/45 degrees C.

I mean, hate to be a bearer of bad news, but if external temps are 45c intake temps are going to be higher than that. It's going to be awful for oxygen density. I think there's a good chance your car is operating at the edges of functional range.
I'm certainly not your engine tuner, and I'm sure people who do tune these may be able to look at logs. But modifying the tune can't correct for everything being hot.
Keep in mind, in the US spring and fall are "Dyno time" for cars like A80 Supras because the 10c or colder weather promotes better power numbers and bragging rights.
