First I had to make a template using the engine and gearbox as a reference, this MUST be done very acurately to avoid clutch problems and gearbox shaft wear. For a short answer, it took plenty of hours, and I had to modify/construct the flywheel. If you are interested, I can give you the full story, but the finished product had no clutch problems or vibrations of any kind. In retrospect if I did the job again, I would not remove as much weight as I did from the flywheel.

Any other comments about this sensor? > > --steve Yes, the Honda sensor seems to be the same as the NTK manufactured sensor except for where the cal resistor is. Horiba has marketing right to this sensor in the USA foe air/fuel measurement. They slap on decal and charge twice as much. This UEGO sensor is a back to back O2 cell with a VERY complex constant current and sensing electronics. Nobody so far to my knowledge has been able to clone the sensor box. The sensor is easy but it is not a voltaic cell like the std sensor and you can't just read its voltage. If you call NTK here in Farmington Hills, MI and sign a written statement that you won't use for air/fuel measurement, they will sell you the sensor for $600 and box for $400. Otherwise its $2400 from the rip-off guys @xxx. BUT there appears to be another solution- the Bosch LSM-11 sensor as used in their LA-2 $5000 air fuel meter. The sensor alone is about $190. I just purchased 3 more at that price from a Bosch distributor. I have the cal tables on this sensor and I also gave copy to Jim. We started to design an interface for this sensor as it is much simpler. This sensor has the BIG ADVANTAGE that its voltage curve is a very close match to a std sensor as thus you can just replace the std sensor in your car with the LSM-11 and then car will run fine on it. Then can hook up your a/f interface box in parallal and read out a/f ratio. The main thing to solve with this sensor is the large temperature correction. The idea was to use a PIC as a controller. Figure out a math function ( 3rd order or so) to match the std S shaped curve, then use the temp as an offset function in the controller. The internal resistance of the sensor changes from about 10 ohms to over 100 ohms and is a indication of the temperature. To give you an idea of the shift with temp, note the following: OUTPUT 650 deg 750 deg 900 deg 830 mv 13.94 13.23 12.02 As you can see if you are tuning for max power, there is a big difference between 13.9 and 12.0 air/fuel at a fixed 0.83 volts. All is not lost, Mike Licht @ Modern Muscle here in Detroit(810-754-0261) is in final test stages of a a/f meter that uses this sensor. Will sell for $800 including the sensor. That is why Jim and I stopped work on our design and are waiting for the MM meter. Interested parties can call Mike @ above # AND if the MM meter falls thru, one can always use the bare LSM-11 sensor by measuring it's voltage and also the temp and using the Bosch data to manually calculate the a/f ratio. This may be more than you wish to know but should be of interest to this group especially since as recent discussions have shown, even MAF cars need to "tune in" the a/f ratio.

I think they did use a Motorola somthing or other in parallel with two 8051's on an earlier computer for knock stuff though. The chip has a large lower case "i" on it, that I would think would be Intel, even the proprietary stuff I've seen from Motorola still has the M on it for Motorola even though it has no number designation.

There are various methods for building a flow bench, but I think the most accurate method is the sharp edged orifice principle. You should also look into how many inches of Hg vacuum your bench can pull (the more the better). Basically, the apparatus should include at least the following components: the blower motor, water column gauges for measuring pressure diff. across the orifice and ambient pressure(this you can make), a set of orifices (you may be able to find this from instrument companies... These are just the basics, but you should get a brochure from Superflow that might give you some ideas. The one thing you can't do with the flow bench is to study manifold dynamics, which are very important.

I'm pretty sure GM EMU's are 68HC11 based, thus the oddball baud rate. In the words of the prophets, you need a lawyer to talk to a lawyer. It would be a simple matter to setup a small 'HC11 module to either log the data, display it, or both.
