What did you do to your Supra today?

Those DME connectors are a pain in the dick. Who designs a connector with a positive lock that can click when it's not locked? Oi.

ze germans.

Today about high noon I went out to get some Sumatra coffee. When I left the establishment, from a complete stop, I went to pull into traffic and it felt like the car wanted to break traction maybe because I was turned… And then all of a sudden the car went into limp mode… Immediately pulled over because there’s no throttle it felt like it was coughing and sputtering… shut the car off, restarted, and it drove normal again. Any thoughts?

pull codes. Car can go into limp mode for any number of reasons

I flashed my car with an OTS map using the MHD wifi dongle and the first full write took only 20 seconds. Isn't it supposed to take 20 minutes? ?

No, it’s quite fast - even the first one as I recall. Now get the car out and enjoy the new tune!

Changed the oil on the car for the first time since owning it. Oil had 4000 miles from last being changed by the Toyota dealership I bought it from. The oil that came out 1. looked brand new and 2. was exactly 6.5l. Soooo guess some dealerships do know what they are doing I suppose. Of course no way of knowing what type of oil they used.

Went for a short drive and it's a nice little power bump.. but I got one of these to dampen the mood.

I presume this is just an artifact of the MHD OTS tune. Oil levels are fine according to the iDrive check. Does anyone know I can get rid of this? Clearing codes on Bimmercode doesn't seem to affect it. Ugh.

Thanks!

I've reached out to MHD but might try reflashing to stock and then back. The MHD manual is woefully incomplete as it seems to have been last updated in 2022. ?

Did you see the mention of using the "download flash later" option? Not sure if this applies or not to your ECU situation.

Not sure. They're talking about BM3 though so same but different.

Yea, but you know software
I'm assuming the historical oil change data is now missing and the system can't calculate the oil wear data. Can you reset the oil change required notification to zero it out or does it need to actually be presented to do that?

JB4 by any chance? Tune, meth or E blend gas? I get this on track when I forget to turn my little JB4 off (rarely do it anymore). But still, she’s muy sensitive to changes. That’s exactly what you do btw. Pull over, turn her off (sit a bit) & restart.

Itll be fine. Had the exact same thing. Goes away after couple of car cycles. Think I even had it come up another time but always went away. I've reflashed it probably 10-12 times and only gotten it twice.

Yeah cool. I've reached out to MHD but will just try and drive it out. ?
