I've emailed to the email address as shown on the DIY WB website but had no reply. Are the PCB's still available? Matt ___________________________________________________________ Yahoo!

I've been trolling for a few months now and have learned a few things. But I still have questions. I am more of a hobbyist trying to keep my car running and operating as inexpensively as possible. My goal is to increase the fuel economy of my new to me car.It is an 89 BMW 325iX w/215K miles inline 2.5 liter 6 cyl with bosch motronic 1.3 (last 3# on ecu = 173). When I got it I could get 22mpg highway and I run premium fuel. Is it someway possible to use a wide band O2 sensor in this application? Will I need to have a new chip burned for the ecu? I haven't searched the archives much but I did come across a 528e BMW (2.8/2.7 liter inline 6 efficient engine, had it in my last 325e) that someone had installed a wb02 into. I couldn't find anymore info other than it was installed. Any ideas? I can do basic soldering and wire maintenance. What will I need to make this work? Also, would a MAF be useful as well? Anybody have one that will work and is inexpensive? If not, I'll probably take the AFM which is larger off the m30 BMW engine and swap the electronics to make it work. Right now I'm running a K&N panel filter, Amsoil 75w90 gear lube in the front & rear, Amsoil ATF in the 5 speed transmission and in the transfer case. Once I replace a leaky valve cover gasket and leaky pressure relief on my oil cooler I'll convert the engine to Amsoil 10w30 motor oil and use a bypass filter to extend my drain to 25K miles. I also installed an ignitions solution plasma booster (multiple spark discharge device) and the car came with "high performance" spiral wound ignition wires from Bavarian Autosport. Without synthetics in the engine is getting 26mpg avg (80% highway, 20% stop&go city). Any recommendations on what I can do to get this car closer to 30 mpg would be great. I plan on keeping the car for at least 100K miles (3years or so with my driving habits). I've got 215/60-14 Cooper Cobra's (only tire i could find in that size) tires on it right now and my winter tire for Vermont is a 185/70-14" Nokian Hakka's. I know tire size plays a big role in fuel efficiency so I try to keep them with a small diameter. Have any of you looked at the kits from SUN auto in Japan for HYPER grounding and HYPER voltage regulating? The grounding kits claim to use 99.xx% pure copper and low impedance, as a result a better ground and more HP, Tq, higher fuel economy etc, the voltage reg keeps a constant voltage on the battery so when the alternator changes speed with the engine or lights come on, etc the battery keeps a constant voltage to all other devices, resulting in increased everything as well. In theory I understand that it may help, but I'm not sure how much it'll help. I have to clean up the grounds on this car and that might help it out a little more as well. I've looked at dyno results etc and they all post increases from these two devices. Hype/Myth? Good idea? Great Product? Waste of money?
