Sound deadening is nearly complete. I managed to use 3x sheets of Dynamat for each door. Lined the complete inner and outer skin.

I will be doing under the back seat and parcel tray next. Hopefully that reduces the fuel pump noise considerably..

Speakers amp and subs are next on the list for purchasing

Minor update:

Fueling:

I have decided to add E85/100 into the mix for a bit more power, so I purchased an ethanol content sensor.

I have also never been happy with my fuel plumbing/filter arrangement, so I am going to purchase a nice IDF750 fuel filter like @Murray_Calavera. Once it’s all here I will work out how to package it all neatly so it’s not that visible in the engine bay.

ECU:

Haltech have released new firmware for the Elite ECU and they have a new MAP prediction for tuning idle @Dose Pipe Sutututu not sure if I explained that right? Anyway, idle is now amazing and so smooth.

Throttle blip is now 95% there! I was driving round with the laptop this morning doing some tuning (keyboard mashing more like it) to figure some things out.

Nice!

Looks like it works well, Andy from Haltech must have pushed for that. It allows compensation for when port velocity is so low fuel that is sprayed is turned into a fuel film.

I think it's called x-tau in other ECU

Definitely better than the classic one.

i have also been toying with rotational idle (for wank factor) and launch control. Any tips for launch control ie. Ignition v injector cut etc?

If you want good brap idle, just have VCT enabled from 700rpm onwards and lower the idle timing in your zero demand table. I have it bouncing between 20 and 8 degrees LOL.

In terms of launch, I really haven't dialled it in as I just use the rolling anti lag switch for launch. That blankets retards 18° of timing and with ignition and fuel cut 100rpm over target. Gives me a little over 1bar of boost at 4500rpm or about 1.3bar at 5000rpm on a roll. Good for those cruise days at SMSP, and shooting flames lol.

Dumb question…How can you change vct switching points with a keypad button?

I don't think you can easily, unless you get creative and set up a Generic output condition to override it.

I just have mine turn from 50°C onwards, car struggles to idle with it on when it's cold lol.

So the quest for “comfort” continues…

The cabin always smells like fumes… I have a feeling that this is due to the VTA catch can setup I have (not a legality issue NZ), as the ATP can puts it right against the firewall, right next to where the HVAC draws air from (well I think anyway). 

I have removed the charcoal canister (not legally required to my knowledge) and cut the lines under the car, which may also be contributing?

I have noticed that ATPerformance do a re-circ version of their catch can, so I will get that and hopefully that helps.

put a small valve there, something that cracks after 0.1bar of pressure, if not you'll always smell fuel as the fuel tank breathes.

I have a one way valve, that cracks open at 0.1bar, some eBay junk. Stops the smell in the garage.

Dose and Duncan, do you guys ever have issues where that valve has vented during a warm day, and then at night the tank has cooled and contracted?

Issues I could imagine might be the old fuel cap hard to get off as a main thought you could see.

 

My understanding is the fuel cap is sealed, or is it meant to vent and allow air into the tank to stop vacuum situations?

Yeah fuel caps allow air in when the tank is under vacuum, otherwise you create a big vacuum as the fuel gets used. Also, as Dose said any fuel vent should have a little spring pressure in it, you are meant to get that pshft when you open the fuel cap on a properly working system

Old school fuel caps do I fact seal the fuel filler neck, however there's a vent elsewhere.

As of the 80s ish fuel caps started to incorporate 1x way valves to allow air in as Duncan has described.

So I have managed to track down some finned RB covers for a reasonable-ish price (think half a crack rock instead of a full one).. These will be getting the same weld treatment, as there is breaks in the fins to fit the intake pipe over the top..

also on the weekend, I completed the sound deadening behind the back seat and on the parcel shelf. It’s times like these you realise how small cars of this era are..

While I was at it and the rear suspension top hats were accessible, I clicked the adjustable suspension to its softest….. but I still cringe when I see speed bumps in car parks..

    • I got a full sheet set of OEM copied stickers to replace all the faded engine bay ones, great quality too.  Came from England. Someone like that should be able to to make u up what u want so long as u have a quality image to show them 🤷🏻‍♂️
    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
