CSET 583 Report post Posted November 27, 2019 I'm a little late to the party with this tune, but finally got around to it. Added shift lights, removed speed cut and selected the most aggressive 'pop & crackle' option as I wish to retain my cats for WOF (or what's left of them). Can confirm that Supersprint exhaust + this tune is something else indeed...! There seems to be a fair bit more you can do with this software, but it's of little interest to me/it sounds pretty risky raising redlines etc. Followed this guy's guide, using BMW flash and ECU worx software: 2 Quote Share this post Link to post Share on other sites

Matth5 471 Report post Posted December 14, 2019 They do not read codes or perform an emissions test, and a check-engine light is not a WOF item. So while it may be a requirement in writing, it is not checked and you will not fail a WOF. I've passed my last two WOFs with catless downpipes, and a check-engine light.

Gaz 1061 Report post Posted December 15, 2019 Just because you pass a WOF without them doesn't mean that the OP will. I can guarantee that it is checked but not every inspector is going to know the location of the cats in every vehicle so it can be something over looked. If they have any doubts then they can fail you 1 Quote Share this post Link to post Share on other sites
Matth5 471 Report post Posted December 15, 2019 (edited) Hmm well I even asked the last WOF place if it would be an issue and they said no, I didn't hide it. Well I don't doubt you, guess I was wrong, but I think more places will pass it than not. You can always ask them beforehand if it'll be an issue, and go elsewhere if it is.

Cab 148 Report post Posted December 16, 2019 I wouldn’t worry about failing a WOF due to being catless - I’ve never had an issue on multiple cars over the past 10 years or so ?? Quote Share this post Link to post Share on other sites

andrewm 236 Report post Posted December 17, 2019 (edited) Reasons for WOF failure from NZTA website A vehicle (other than group L vehicle or a class MA or MC motorsport vehicle with a valid motorsport authority card) that was first registered in New Zealand on or after 1 May 2010 and manufactured from 1 January 1990 has a catalytic converter removed where there is evidence that one was originally fitted, and there is no written evidence issued by an entry certifier that the vehicle passed a prescribed metered emissions test in this condition Edited December 18, 2019 by andrewm Quote Share this post Link to post Share on other sites
Matth5 471 Report post Posted December 18, 2019 Edited my original post so it doesn't mislead anyone. So it is legally a WOF fail, but you probably wont have much trouble getting a WOF regardless... Quote Share this post Link to post Share on other sites

CSET 583 Report post Posted March 2, 2020 Some minor updates. Removed & replaced side glass tint (front & rear) with super light & legal 50%, poor tinter had to work around the rollcage. Got a bit sick of the gangster dark tints, they're great for privacy but you simply can't see outside at night (which is when this car gets driven mostly). I need to finish off one side window and remove the rear windscreen to re-tint, too hard basket for now. Old quarter glass: New quarter glass: End result, still looks classy but not super dark. Also painted front splitter again. Finally got around to getting some proper wing mounts designed & made, some renderings from the designer below. The hollow parts will face inboard, should look quite good. Quote Share this post Link to post Share on other sites

CSET 583 Report post Posted April 6, 2020 Pro tip: if you're planning on removing tint, do it before you weld in a rollcage ? This is a job I've been putting off for a LONG while. Quote Share this post Link to post Share on other sites

Leaves much less residue over. Downsides are it can lift fabrics (as it loosens glue). Steamer, plastic blades and prepsol made this job much easier than it should have been. 2 Quote Share this post Link to post Share on other sites
m325i 709 Report post Posted April 7, 2020 How hard / risky was it? I want to remove my tint, but its like 15+ years old and I'm scared of damaging the demister. I'd pay someone to do it, but scared they might too. 1 Quote Share this post Link to post Share on other sites

I'd pay someone to do it, but scared they might too. It's not hard but if you haven't done before definitely see a pro. If you're looking for a recommendation, I'd say Seth at Tint Lab (used to be Car Folie). He has extensive experience in this - I know, because he did my rear screen a few times way back when. If you want to get a hold of him, www.tintlab.co.nz or just come and see me (his new shop is at OCD). 1 Quote Share this post Link to post Share on other sites
CSET 583 Report post Posted June 17, 2020 New wing struts ready to go, need to (finally) fit up the GTR vents and new bonnet & bumper. Dusted this car off after a lockdown under cover, drove it in to work & planning next steps for the build. With the rebuilt engine, new diff & drivetrain parts now installed this car 'should' handle a little more power. 2 Quote Share this post Link to post Share on other sites
CSET 583 Report post Posted June 28, 2020 Progress..! I've swapped over the bootlid to the OEM facelift one & disassembled the spoiler in prep for GT Refinishers to mount up my new struts. Also ordered a new rear diffuser from Fancywide in Russia. Also had the glass tinted in super-light 50% film to help protect the interior trim by Seth at Tint Lab. This is well within legal limits (being much lighter than 35%), and looks quite classy whilst not sacrificing heat rejection or UV protection. 1 Quote Share this post Link to post Share on other sites
