Stock Turbo BPU++ HP record

I always recommend datalogging when doing a dyno pull. Its a lot more helpful in diagnosing problems than just reading the code

WMI + Boost controller, my guess is he's running a BMS kit that requires back-end flash

Burger hasn't released a kit the Supra yet and the BMW B58 kit isn't a direct fit injection plate different

Exactly why I said my guess. I also think you're thinking of port injection

JB4 controls the water meth and then with it we also can work around some limiters with shifts and boost

Hi,

Sorry to bump the thread again. Did you find the root cause for the:

CD990B Message (request, rear axle speed, 69.3.4) missing, receiver DME, transmitter DSC

and

CD990E Message (front axle speed request, 69.3.4) missing, receiver DME, transmitter DSC

?

I got those as well and even driving normally I have them. This after being in the drag doing burnouts, but still I cleared the codes, drive normally and the codes are there again. No CEL or anything, I don't know if should worry about it.

doing burn outs and hitting the revlimiters will trow the car into limp mode without notice or massage

other than that limp mode free
.

Hi, sorry if this has been covered somewhere before but i have the similar four codes listed below since day one purchase of the vehicle and am wondering if a serious issue and how to resolve it:

• CD990B
• CD990E
• 21B056
• 21B055

I recently had an unsuccessful ots flash over the weekend and reverted back to stock since but have noted some minor problems that popped up ever since the visitation to the Dyno, namely chassis and drivetrain limitation.

A quick scan revealed the following codes 120308 and 120408. Am about to take my car out for a drive after installing the JB4 that I was hoping to run a BEF with and will monitor how it goes.

Grateful if anyone can share any insights as our local dealer don't bring in Supras and so am relying on my limited BMW knowledge.
