are these legal? or do i need a cert for them?

It pays to keep an eye on the cerification thresholds as they like to change stuff every once in a while. Especially if someone tells you that you can't do something.

What they say goes ;)

I've just read this as well.

Was surprised to see that any turbo substitution or ECU modifications require cert.

Good thing most WOF guys don't know what size turbos come on our cars, otherwise it could make the vf22 swap a bit difficult.

Or am I interpreting that bit wrong.

I beleive it only applies to non-oem modifications.

On the second to last page it specifically says cert is required for turbo cars.

Seems a bit un-fair considering some v-tec hondas put down similar power and could equally benefit from an ECU chip.

IIRC you dont need to be certed if your increase is within a certain percentage of the factory power rating.

yea thought it was only if you increase power by 30% or more

20%.

But as mentioned there is the note stating that "Certification is Always require for the fitting of a supercharger or turbocharger as a modification, or the substitution of a turbocharger or wastegate, or the re-chipping of ECU's in turbo cars."

So you are supposed to get a cert even if you swap your vf23 for a vf24.....

So whats the go when a 250T has a Ej20tt as an engine swap? because its not a a turbo being fitted "as a modification"?

Fitting a turbo engine into a previously non-turbo powered chassis is a modification.

Requires a cert. And a hoop around the driveshaft. Read the whole pdf.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
