I'd be interested in those, curious to see them.
...In other news, now that I'm back from SEMA and mostly caught up I figured I would actually tackle the tuning of the bug. With the wideband hooked up I'm far less worried about blowing up the motor, so I poured a glass of wine, hooked up the laptop and pulled out the screwdrivers.
I just getting started when something caught my eye, something I would have never caught without the Weber doors. Seems my 3/4 accelerator pump cover lost the pivot pin. Crap! Where am I going to get a replacement for that?
Oh wait...what's that on the Colt?
Spare, genuine, Weber parts! Fortunately Empi's Chinese suppliers are good 3D photocopiers, and the Weber pump cover popped right on without problems.
With that, it was back to tuning. The way the carbs were originally setup up (by ear, and rich). I was running at 11.5:1 at idle, dropping to 10.5 under full load. In other words, very rich! With the Wideband I was able to set up the sitting idle at 13.5:1. The result of which means when I'm driving around town I'm seeing anywhere from 13.5-14.5 under partial throttle/loads, and then going to a 12:1 ratio under full load.
WOW what a difference. I seriously should have done this months ago. It's crisp, any of the running issues or quirks are gone, and it's got significantly more power. Took a buddy out in the car (who's been in it lots) and after a single pull on the highway he was asking about what new parts I had put in the engine.
Of course, now that I have a sweet Wideband setup, I need to figure out how to protect it from gravel...
Vibrant Performance & DCI Heat Shielding to the rescue. Technically I'm not using the product as designed, and I will need to build something a little more robust down the road...but Totem rally (snow and ice) is this coming weekend and I needed a quick fix to last a few days. This material is rock solid with the curve, and even my ball peen hammer wasn't making a mark. That pretty much tells me it will be folded around the O2 sensor by the end of the weekend, but probably won't allow the sensor to be damaged :P
I picked up enough of the material to protect the exhaust wrap on the muffler as well, but will wait until after the weekend to re-do the wrap. Snow tires should be here tomorrow, and I can finish packing the car for the event. I won't be racing this one (I'm event steward) but at least I will get out for some fun roads and winter sliding.
