-I have the single mass with organic+sintered discs. -it's very easy to use, for day to day driving and when you start to be more aggressive with it, boy does it perform. -BUT! clutch chatter is pretty intense with the single mass and be prepared to upgrade/stiffen up suspension mounts as...

general rule of thumb: when you increase stiffness you need to increase grip to match. I have the brace on my MT Supra, in my opinion whilst it can be more eager to let go, it does so in a much more predictable fashion. I guess its personal preference as to how you would like to setup your car.

thanks for this, i am asking PTB about this as i cant see any high/low setting on the bearing supplied to me by PTB.

-which bearing are you using? OEM? -you should definitely remove the CDV if you haven't already. -I went the sinter+organic disc with the performance pressure plate. I will be interested to see if it changes at 2-3k miles like you said. -i get the same shudder in reverse already at 1k miles

no shims were supplied by PTB, and after about 50 emails back and forth with PTB there was no mention or suggestion to install a shim, the issue was blamed on the master/slave. I'm a bit disappointed with the support from PTB about this. Do you know where I could find/purchase some shims?

has anyone successfully installed the PTB clutch with the PTB supplied release bearing without any issues? I installed the clutch and the supplied PTB release bearing and I couldn't get the gears to engage, not without really forcing it, it was undrivable. The friction point was all the way at...

BMW part# 21526785964 this part number didn't work on my car - 2023 MT supra. there was no clutch engagement, no pedal feel. ended up putting the stock one back in and removed the CDV

does anyone know if there's a difference in the installation between the auto and manual Supras for the BM3 flex fuel kit? found this detailed video, but doesn't mention anything about the transmission. I ask because I know the MHD kit says auto only, and the Fuel it kit requires different...

yeh I'm not touching boost below 5000k, learnt my lesson ?

i also nudged up boost slightly, is this ok? 1500 - 1.1 2000 - 1.6 2500 - 2.1 3000 - 2.6 3500 - 3.1 4000 - 3.6 4500 - 3.6 5000 - 4.6 - to 4.7 5500 - 5.6 - to 5.7 6000 - 5.6 - to 5.7 6500 - 5.1 7000 - 4.6

Great, I'll try FF 32 and PID 22. ok, in that case I won't bother with DWP.

I'm very conscious of going down another rabbit hole, but say I wanted to improve responsiveness slightly would I: a)reduce FF? or b)reduce PID ? or c)increase DWP?

@ColonelAdama - miracle worker, it's never driven so smooth. obviously we were asking too much from it before. if this stays like this, this is great, as long as it doesn't change when the ambient temp changes. fingers crossed.

Thanks @ColonelAdama i'll give it a try with exactly these settings, hopefully that can keep me going until I can budget for Femto

my bad, I think I didn't clear the code properly the first time. I think I was supposed to lock the car, go away and come back and restart the car for proper clearing of the code, or something along the lines.

the 130716 error is just the tip of the iceberg, the main issues were the constant stuttering, throttle closures, flat spots in the power band, low boost errors, works perfect one day and then a change in the ambient temperature causes the car to drive completely different the next day. Below...

@razorlab thanks for explaining that - that must be it. HPFP - sorry noob here, this is maxing out the fuel pump? is that because of the Ethanol, or simply generally asking too much via the JB4? Honestly it's been issue after issue with the JB4. I think Terry still has some work to do on the...

I unplugged JB4 entirely, cleared codes again, everything is now back to normal...

first time post - 2023 manual supra - mostly stock (no exhaust or downpipe) i have been recently playing with a JB4 + E20 and I noticed the engine sound change. i tried recording it but its not significant enough to hear on a video. -only under WOT acceleration. -engine performance not really...
