my tuner seems to think that my spark is been blown out with excessive boost.... above 16 psi it missfires etc but at the 16 psi it has about 300rwhp or so... im just wondering if it could be something in the tuning of the microtech.... i have irridum plugs gapped to .6 mm..... im just thinking the coil packs may not be putting out enuf spark/strong enuf spark... what sorta power at the wheels are the std coils and igniter setup good for on a r32 rb20det??? cheers guys...

I have a feeling i know which tuner your talking about too. Cause they told me the same thing. I used to have the same problem, the tuner changed the plugs to a v-Spark plug or something along those lines, but the plugs didnt last all that long. I have just changed my plugs to irridiums and its started again, and im only running 10psi :)

Mine only seems to do it after abit of a drive on the freeway tho. If i punch it while on the street its sweet but drive bout a half hour on the freeway, then decide to give it a squirt it'll constantly misfire. I'm actually in the process of sorting this problem out with the mech that put the new plugs in. When he finds a solution i'll let ya know ;)

Hmm, doesnt sound right. I have seen stock ecu, stock ignighters with irridium plugs (I 'think' they were gapped at 0.8) running 18lbs with no probs to 8200 redline.

I have run up to 1.5 bar on R33 with stock ignighters on iridium gapped at 0.8 no probs.

Have you taken care of fuel?

16psi isnt really huge boost. It may be worth dropping Clint32 a pm, I am 99% sure he runs more than 16psi on his R32.

      [HOW-TO] Winter Steam-Clean & Odour Removal in 30 min

      We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.

      This is mine, works a treat for the cars, suction is good, I use the Bissell clean and protect stuff I have found giving it a good spray and light scrub with the soft brush on the head of the nossle for carpet, and a rub with a microfibre for cloth seats and cloth door trims, prior to another quick spray before vacuuming it up works the best @GTSBoy You would surprised on what it gets out of carpet and seats that actually "look" clean, I recommend that you test drive yours when you have a little time to kill, then post pics of the muddy looking water that I believe you will find

      I think even the "commercial" capacity ones that you would hire from supermarkets etc wouldn't have the capacity to do all that much in one go. I will go through half a dozen tanks of solution and dumps/rinses of the waste tank for one little 2 seat sofa. Or similar for one 6 footish rug. That's the price you pay for something small that only takes up a bit of cupboard space, instead of something that takes up the entire laundry cupboard or half the shed.

      Someone needs to copy it, improve it aesthetically, make it DBW ready from day 0 and send it to the motherland Chynah for my relatives to cast it and mass produce it 馃槄

      U read my mind, going to machine it off or get a high temp vinyl etc stick on plate made up. There鈥檚 so many other ways they could have made it look cool. Have the option anyway as I need to cut off the throttle body flange and get the dbw flange welded on.
