To have a guage that tells you your lateral G's like a gtech, but what what the actual atts computer sees. I think this would be pretty trick.
Anyone have any knowledge??

If you're asking here, I'd say you're in over your head!

If you have knowledge of electronics, I'd dig into the helm and get after it- they should have a basic explanation of how it works. You'd end up having to make an LED or similar bargraph or digital readout. Easy enough if you have the background.

Good idea- I'm susprised no one has come up with something for it yet. What's it worth to you

A dollar. Interested? lol
I was thinking the same thing as far as I've never heard anyone talk about it. I'm guessing that it would be pretty simple for someone with experience, but I don't want to cut any more ecu wires myself(V-AFC).

if you figure out how it works and you want it done, explain it to me. i should be able to make any kind of readout that you'd need.

The Helms says that the connector for the Lat. G sensor is located right under the middle of the dash. This is under the "Connector ID and Wire Harness Routing" section. It is the C451 Connector.

The electronics wouldn't be too bad. I know there are a few people here that could figure it out (I'll bet I could but it would take me forever). The bigger question in my mind is what type of display to use. A simple digital read out, an analogue guage, or a data logger of some kind. The type of guage will effect how comlex the wiring is.

But yes it could be done.

yes this is a topic brought back from almost 3 years ago

but this seems like a good idea, one that I had when I first got my Helms manual and was looking through the section on ATTS.

The ATTS has a lot of neat sh!t to it that needs to be tapped. The lateral G sensor and the yaw sensor are just two off the top of my head.

How could you take the voltage, convert it to a voltage that a bar graph led readout or for a digit type readout so we could read it?

A National LM3914 would do the trick. Same thing the Autometer a/f gauge uses. Unless you have a knowledge of electronics, though, you will be in over your head.

that's the bar graph driver chip isn't it? Using that will give a basic read out of the lateral g voltages. Will I need some sort of voltage regulator with that you think? I know I'll probably need a variable resistor to adjust the resolution of the display.

The LM3914 would provide a bar graph type display according to the voltage readout from the sensor. To me this is pretty useless, as all you'll be seeing is a bunch of lights.

IF you were interested in getting a digital readout, you would need an A/D converter(for example ADC0801) to convert the analog voltage to a digital readout. Then by using an EPROM, you could program each voltage to a specific lateral G reading. From there forth, the EPROM would be used to supply the equivalent lateral G reading in a digital(binary) format which then could be used to drive a 7-segment display or LCD.

Not a hard job, but needs some planning and testing...

do you (99_sh) or anyone else know any good books or forums that discuss building circuitry like this. I'm very interested and have a big fat catalog from DigiKey in my hands right now. I just need to get some more resources on this before I can proceed and I don't know what exactly I'm looking for yet.
