R&R = Rich and Retard (kinda like Paris Hilton but with less skank)

the standard R33 ECU will modify the air:fuel mixture by making it run rich and retard the timing when it senses something outside it's expected parameters.

quick lesson.

air goes in through the air filter, goes past the AFM (air Flow Meter) which sends a message to the ECU saying "Hey bro.. there is 12 air habibs coming your way"

ECU goes "No worries bro.. I'll douse them with 2 bits of fuel and burn the f**kers"

the air (habibs) go through the turbo and get all hot and angry like a bunch of lebs that just did 14 sets of bicep curls in a power cage, then through the intercooler to coll off a little, then in to the motor where they think they are entering a hektik nightclub only to be doused in fuel and burnt and spat out the back of the turbo and out the exhaust.

so..

The AFM (lets say is a Kiwi bouncer.. you know.. tough, but can't really count much) can only measure up to a certain number or air.

when you use a boost controller (lets say a hot chick bro), and you turn it up (reduce the length of her skirt and shrink the top), more air gets forced in to the engine (lots of habibs get calls from their cousins and they call go to this place and try to get in).

The AFM can only count so much and realises that there is too much air going in so sends a message to the ECU saying "Bro.. I only counted 15 habibs but I think that another 10 of their cousins snuck in... I'm not sure hey.. I didn't learn to count that many"

ECU goes "f**k you're a stupid coconut c*nt... now I have to deal with these habibs"

So as the habibs make their way through the turbo and intercooler (no doubt stealing stuff along the way), and in to the motor, the ecu douses them with heaps of fuel and makes all the habibs really wet with fuel.. this means that when they are burnt off, they don't burn well and so come out as darker smoke.

Because of his bad mixture (too many habibs in the one club), the ECU also retards the timing (closes the bar for a while) meaning that everything works really badly... all to protect the motor (hektik club) until the AFM (bouncer) gets his shit together and counts properly.

all this means that your car will jerk as if it's hitting some sort of cut or has a fault..

but it's just your car's way of telling you there are too many habibs.

How do you fix this?

Cheapest = A signal bender of some sort (Apexi SAFC is probably the cheapest)

this is a device which teaches the AFM how to lie to the ECU.

You turn up the boost, and 30 habibs arrive and run through the entry door..

AFM goes to the ECU "Hey bro.. I've just sent through 18 business men hey.."

Ecu goes "thanks mate. I'll give them the fuel needed"

this means that you get a leaner mixture and it all makes more power.

a better choice? after market computer.. there are lots to chose from.. do a search.

the after market computer (replacement for the ECU) is fully programmable and so can adjust timing too.. it can also mean that the coconut at the door doesn't have to lie, but instead, it is send on a few special classes and is taught how to count..

Hope this helps.

so, more habibs is actually desirable?

I would say yes it would be safe to run it on 10psi.....depending on what purpose your using the car for....ie daily driving then no problems...

If i were you then i would invest in dump/front pipe and a high flowing cat so that the exhaust gases flows a lot better....and then you can increase the boost to 12psi and not worry about anything....enjoy the more boost

If you want to move fast or have more power, I think it's obvious why more habibs would make this happen.

ECU needs to know how many habibs (air) are coming in da club so that it can get the spark plugs (chicks) and fuel (had in the shape of a gun) and then???

CHK CHK BOOM!!!

everyone should be happy now. :)

      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).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
