Just PM'd it to you since it's my personal Google drive, don't want it on here lol.

Broken links unfortunately, but honestly I need to hit up Kale and see if we can host a lil Supra thing there!! That shop is damn cool, and not far at all from some excellent upstate roads

Looks great!! Good spot to keep it. Seems like all you can get out of the current fuel.

It honestly doesn't look too bad, but yeah probably need to dial off boost a little. Try this map 6 out. Remember to set FF back to 25 map6_15 map6_20 map6_25 map6_30 map6_35 map6_40 map6_45 map6_50 map6_55 map6_60 map6_65 map6_70 0.6 1.1 1.6 2.1...

Send me a PM on this forum!

@Got_M let's see your 60-130 lol:cool: That's about as max-effort as a JB4 will go (E30+M1 meth) I have posted a few dyno charts in this thread from folks running my custom maps, generally 435-440whp on 93 octane, and 465-470whp on E20-25ish. Ultimately, it is only the gains over stock that...

Exactly this, except I think we are a couple years out from Kimi at Merc. Williams is bidding for Sainz apparently, and I would guess if he ends up with RBR instead, Kimi may end up in a Williams before Merc.

Yeah 1st would definitely spin ?

Tune definitely needs some love ? Give this a try: Switch to Map 2 Set FF to 25 These Duty Bias values: duty_15 duty_20 duty_25 duty_30 duty_35 duty_40 duty_45 duty_50 duty_55 duty_60 duty_65 duty_70 50 50 50 50 50 50 50 55 60 65 65 65

mine hooked in 1st while stock too. JB4 on ethanol blend and I'm lucky if 2nd hooks.

Nah not really, doesn't reduce rev hang

How is 70k a bad deal for a Z4 6MT when the MT Supra with the last gen interior and no convertible top is 60+ now? +10k for a modern interior and automatic roof seems reasonable to me :dunno: Aren't base model 2.0 718s the same price?

Has anyone actually figured out what the failure mode is? I still have zero slip on an early 2023 car that makes well over factory torque. Whereas on my GTI, as soon as I went above stock torque, the clutch was toast. Seems like its not really a clutch material/clamp force issue like that car...

Only on A91s. Black badge on my MT

No, that is why they are in high demand. Has a cat simulator to prevent CEL I have the 3.0 one and no CEL in 2500 or so miles

Toyota and BMW already said it is dead in 2026. Who knows if we even get MY2026. 2025 model might be it.

I drove my car pretty hard thru the winter months in the 40s and killed the rear PSS w/ <5k miles on the car ? woops definitely learned that they don't quite hold up in the cold.

Nice kill!! That's before we even finish getting it dialed in! We would need to re-do duty bias and FF for the new DP, but shouldn't be too many revisions to finish.

Yeah just to add to this since the thread has been bumped: MT cars are generally no problem to tune anymore. Have done 6-7 cars in the last month or so. The MT firmware and low WGDC method has worked well. Still not as easy as an AT car, but seems fairly repeatable. Thanks @RyanA90 for...

It is high flow catted. Catless have slightly different FF and duty bias. On 91/E25 Plotted: ECU_PSI vs Boost (essentially your entire JB4 power gains - provided that timing stays up - shown purple) Baseline run - choppy boost and throttle. After MT firmware and tuning: It only took a...
