Guys the E90 slave is like $45... Just buy one. Lol

I just rolled 1200 miles with my MT and it seems like the ECU is doing less torque limiting around torque peak. If the MFG is doing any power limiting its definitely just a peak torque limiter down low in the RPM where the stresses on the motor are really high. I have a pretty involved...

I just swapped to the E9x slave and can tell you its a vast improvement over the delay valve setup. The slave is: https://www.fcpeuro.com/products/bmw-clutch-slave-cylinder-21526785964 Immediately noticed that engagement is actually in the pedal feel and not smoothed out after the fact... 1st...

So what you're experiencing is mostly the PID control of the ECU moving the throttle blade at a slower rate. Basically think of the throttle blade as a constantly moving target and the ECU is always trying to get it to the requested angle as quickly as it can. In sport and normal modes these...

Its such a waste.... they're having zero problem moving B58 cars yet they want to waste production on a lower margin 4 cylinder thats literally not a good value...

If the ROM needs updated in the future can it be done without going back to femto?

:bow:

No, the rev match will be improved with this because instead of you letting the clutch out, activating the ECU switch that you've done so and it resuming throttle, it will now act like it should. I imagine the CDV was added to help novice drivers... i think just running open downpipe would help...

I've done H&R Springs, Eibach sways, Tomei single exit and about to work through a custom alignment. Very happy with my car, I'm looking for bushings to firm up the shifter, feels to soft currently.

I absolutely LOVE bootmod3, its been the needed change in automotive tuning software that we've needed for a long time. I've had BM3 for both my 15 M4 and 18 M3 and for OEM tuning there is literally nothing better on the market for ANY ECU. The wait is 100% worth it with those guys!!

Finally someone who doesn't think the Pilot Sports are the best thing ever! I absolutely HATE PS tires... I think theyre ugly and the traction is medocure at best. Id rather run a kumho ps91 than a Ps4 and then i'd at least get 10k miles on a sec.

Stage 1 complete: :rofl:

Toe can heavily affect the wheel rotation speed which will make traction control more suspect to trigger. Its likely an alignment issue if your tire dia match front/rear for whatever the stock ratio is.

I feel like I have a pretty bias opinion about cars and have owned a lot of really high end cars in that 50-100 price range. 03 - IS300 08 - STI 15 - M4 18 - GT350 (exploded, ford buyback) 18 - M3 Individual (Couldn't stand exhaust note... s55 tt sounds like balls) 95 - Supra MKIV 3.4 stroker...

I would strongly recommend getting that thing checked out... if you're getting smoked with a catted downpipe its probably already clogging the cat with oil sludge and then you also have the "reason for smoke" to solve..

A "ploom" of smoke is oil consumption somewhere.. could be a lot of things, rings, PCV system, turbo, gasket.... I assume catless downpipe? You wouldn't get smoke with a cat.

Bumping this thread. Is your throttle more reactive and does the engine rev down faster with tuning? My biggest complaint so far is how badly the rpms hang with the MT tuning..

BMW DCT is absolutely fantastic. It behaves like a manual in everyway outside having to shift it yourself! If the supra was available as DCT vs ZF 8 I would take that over a actual manual.

Ordered the E90 clutch slave which is a direct bolt on without a delay valve. https://www.fcpeuro.com/products/bmw-clutch-slave-cylinder-21526785964

I wanted to chime in on this thread because I have some opinions I'd like validated. 1. The shifter does feel "rubbery".. already looking for bushing inserts to "harden" that up. 2. The throttle tuning feels awful, 1st gear is almost impossible to shift smoothly into second no matter how hard...
