Surplize modapuckers lol

This happened today, driving back from work like a normal person. Doesn't happen when I drive like a complete knob, or launch it at 4k.

Anyhow tried off and turning it off and on, that didn't help ?

So headed out to pick up the missus in this shit box, and spanked the limiter, she didn't like it.

Lol yeah but considering it's not even 1.5 years old with 17xxx kms on it, it's a joke!

Modern German cars have a system built into the BMCs and CAN that turn on one of a set of random errors each 18 months for the life of the car to ensure you get rid of it and buy a brand new one just after warranty finishes.

It’s why as cool as I think the golf r is I’d never own one, I’d look at either an sti or the Hyundai i30N

Man my back is sore lol. A fixed bucket seat, semis, several solid suspension arms, rock hard suspension but yeah ended up doing over 450km today. 1.5 tanks of fuel later ?

Good drive with @PLYNX and my mate in his R33.

Okay, admittedly it was pretty fun and first time I've actually stretched the new setup with a lousy tune. Shoots flames, 11:1 afrs, lazy 10 to 12 degrees of timing but it is wanting to light up 255 Nankang AR-1 semi slick tyres. Still need to swap out thr gate spring to a softer spring, running a 4 port solenoid and with a 1bar spring there's very limited resolution, kept spiking and hitting engine protection.

I'm sorry I missed the run.

 

I've spent the day yelling at people and driving back from sunny Singo

 

Glad your beastie got to stretch its legs.

 

What's next for the 33, back in the garage for a spell?

Umm no idea to be honest, I said I'll try go once a month with @PLYNX but knowing my life, even that would be hard to achieve.

 

And here's a dose video and some gate, wallah swear to god I didn't use the photo illegally (didn't talk or text or use social media) lol

What spring are you planning to swap to and what max boost are you chasing?

0.5 bar and will run up to 2 bar.

At the moment trying to command 1.3 to 1.4bar is very challenging. Every 1% to 2% change in duty cycle is jumping 0.1 to 0.3 bar of boost. By dropping the spring you end up with higher resolution. Just some idiosyncrasies with running a 4 port. Running a 3 port but across both ports on the gate is a simpler solution which allows decent control too, but I wanted to try out a 4 port setup, so here I am lol.

LC video to see if the gearbox is still tight

Can't for the life of me think why it would be showing signs of fatigue or damage

Well it's there to use right? lol.

That's why people run boosted engines, to get twice the atmospheric pressure

 

[No Crust Racing]

For sure, and why they don't live a long happy life lol 

[Count Grantleyish]

Looks fine to me, keep launching it y0.

Another solution I've come up with for another car I tune which granted, we've not tested yet - and I don't know how flexible the Halaltech is with settings and available outputs, but we're running 2 MAC valves and running one of them against a fixed PWM look up table to "bring up the base pressure", then use conventional boost control to drive the second one as an effort to retain 3-port style table granularity but give a 4-port style boost range.

Interesting, is that similar to how anti-phasing works? I hear that terminology thrown around a bit however given we aren't in race cars or F1 cars I've never bothered to read further nor investigate further.

4x port was already going into another level for me haha...
