I like the old-fashioned way of tinkering with the Zed, just like my home-made PWM light dimmer, so I'll keep working with the DIY stuff, unless you'd like to buy one or me
-
Unfortunately, the car is put away for the winter, but I will be making a script to carry out, as this stuff like ZedHead suggests sounds reasonable. But usually, I keep light pressure on the gas, so the revs are probably about 2000 - 2300, for 45 or 55MPH (for country roads.) Too bad you can hook up the BT OBD recorder, like the other car has. Recording the engine tach would not be easy, unless you can hang a smartphone around your neck, but I will see if I can fab up a bracket or something.

The best sensor to use would be the wide-band (4-wire) ones, but I think those have heating elements in them, which requires something more than just connecting the wire to the battery. Is there any idea what could be used?

It seems to me that when you stomp on the gas pedal, it takes a few seconds for the EFI to catch up to throttle opening wide or the RPMs. Is that about right? I think modern cars can react faster so you don't notice it, but when you are on the highway or a country two-lane road and you want to pass, having to wait 10 seconds (forever) can be scary, especially if you see a truck coming your way. Is there anything you can so with the Bosch L-Jet to help with that condition?

After all the work to design a PCB and collect the parts, I found a kit ay jaycar in Aus. https://www.jaycar.us/display-fuel-mixture-module-ego-10led/p/AA0374 Right now, I just want to get 'a' sensor so I can play around with the thing, Sometime after Christmas, I will look into ordering a new sensor. BTW I figure you can get a sensor from any 4 cylinder car? just look aft of the catalytic converter? Maybe there's one even before it. I'll let you know if there's any progress, but the thing really isn't of much use unless you thread it into the header pipe... The reason this sensor interests me is that I'd like to figure out what I can do to fix the lean condition you get when you stomp on the throttle pedal.

By-the-way: just inserting an oxygen sensor into a tailpipe is not going to be enough. You need to push it as far as possible so you will get an honest reading. I've read some DIY discussions on this subject where the builder chose a length of small-diameter copper pipe, or a long welding rod, etc.

I'm going to make an air-fuel ratio meter finally. I finally have reviewed all the relevant information, like narrow- or wide-band sensors, or how many wires on the sensor. I found a schematic and developed a PC board, and ordered the parts. I still need to get the sensor (a wide-band sensor) which I could get from the JY still this year, weather permitting. I'd like some advise as to which types or models of vehicles would have a wide-band sensor. I suppose I would just take some vice grips and climb underneath to unscrew the thing,. They are about $10

That plastic lens cover is out of stock. Right now, I need to find an original cover in about any condition, because somebody touched mine and it fell apart. Does anyonehave a spare?
-
It looks like I got the engine drained just in time. It froze last night, and the weather forecast for the next week is for cold and snow. I will just fill the thing with water in the Spring, with some Water Wetter. Is there an anti-corrosion additive like you get in antifreeze? Water Wetter only provides a lubrication improvement.
-
I like the idea of a bulb with both radial LED chips and a projector end.
-
I am in no need for a dome now.. A retractable wire would be nice too, but then it might be a little too modern. The LEDs would be the limit of the modern-ness.
-
Go your local super store that stocks every kind of energy drink and tell us which one it is.
-
I did finally find a website that will provide a list of compatible tire sizes for most wheel sizes, and for my 4x15 wheel, I'd get a 175/80-15 tyre. It's just about the same circumference and will fit almost flush with the rear deck.
-
I have recently thought of this myself... After making a cardboard pattern of the bottom of the plastic dome, I browsed the isles with the body sprays, hairsprays, deodorants, etc. and found a bottle of Neutrogena facial cleanser at a local discount grocery store. The clear cap matched the pattern fairly well, so I bought the bottle. When I got home, I found out that it fits perfectly over the old dome. Now I only need to trim the old dome close to the base, and glue the new one onto it. It's too bad the kids don't visit any more, as they might be able to use the ($6 bottle of ) facial cleanser, so it went into the trashcan. It would be nice to have a better replacement for the dome, probably made of lexan (something that won't discolor from heat or underhood fluids.

Thanks mate, I was never able to find such a comprehensive explanation to all the different tyre designations, even on the tirerack website. Every place I looked tells you about the P-metric system, or the American system. (such as 23x6-15) http://www.tyresizecalculator.com/tyre-wheel-calculators/tyre-size-for-rim-size-width-calculator
-
That is a popular tyre size for that size wheel.
-
Thgis is a little off-topic, but what size tyre would you put on a 15 x 4 inch wheel? 105/70-15 maybe?
-
I found the same page long ago. It's too bad there was no consistency or sense with the tyre information of long ago, like there is now.
-
We are not debating the correct tyre size for a Zed. The question is: what is the equivalent modern tyre size for a period tyre of 225VR15. It appears the aspect ratio is 70%, but there hasn't been a consensus so far, nor any official literature or trusted Internet information to refer to.
-
The Michelin XWX tyre is the current version of the XVS tyre, and is an excellent touring or racing tire, especially on classic cars. It is a development of the XAS racing tyre used on many cars in the 1970s. It is the equivalent of a 225-70-15 tyre which is what I was using before and is also the recommended size for the Zed. I just can't find any facts that the aspect ratio is 70% or 80%.
-
I was looking for an equivalent for a Michelin XVS 225VR15 tyre, and I realzed that it is not the usual format for tyre size. The 225 is the tire width, the VR is for V speeds (149 MPH) and R means radial, and 15 is the wheel diameter. Do tyres like these have an aspect ratio, as in 225/70-15? Is that even an American tyre size? European size designations are entirely different. Internet searches reveal nothing about it, only the usual metric tyre size that you see on most tyres.
-
I would not mind, if it got better fuel mileage, and bolts to the Jatco transmission and my steering pump. , not that I need "horsepower" My L28 is almost 3,000 cc anyway, after the cylinder walls were "cleaned up" when the engine was out.
-
Yeah, I was considering draining most or all of it, then putting it back in for Spring, but I first wanted to circulate some good stuff with the additives in it. It's too bad you can't just get a bottle of something with the additives to boost whatever coolant mix you have (or maybe there is.)
-
What I did was to drain a gallon of whatever the mix is, then I topped it off with a gallon of antifreeze. In the Spring I will drain the whole thing and fill it with distilled water & Water Wetter. Evem if you drain the cooling system, there is still water in it somewhere. Maybe someday someone will come up with an additive that is just good enough to keep the water in the engine from freezing so you can store the car.
-
Does anyone have any good practices they can share, besides using things like shoelaces and a pressure washer? If you have a long wheel brush, should you get a certain type? Is it of any benefit to use a cone tool on a drill? How often do you clean the wheels? Is there any kind of special maintenance you do to the wheel besides the cleaning? thxZ
