This thread is for us who like the new feautures of FT and wish to share experiences.

My hope next is to find out more on the practical exeperinece of inclination/wheelie Control feature.
Sensor options needed and experience.

Hi Frallan,

i started to work on the wheeliecontrol...
Fueltech says to use ridehight sensors but I use damper travel sensors on the front and rear.
So when i recoginze a wheelie i started to Retard ignition. But it was just a first try.

on my new car I Need to get experience first to start working on this again Wink

Cheers,
Basti

This is one of the sharings/news I hope to hear abot about from you Christiano.
 Grin


If a FT500 thread starts, I can jump in with some cool stuff whenever needed.

Right now I'm writing an article about the anti-wheelie control and some successful tests we have done at the track using sensor way cheaper than the freaking expensive $600+ Racepak one that most guys in the US are using.
Can't give much details right now b/c it'll be published on a performance magazine, but as soon as we have everything set I can translate it to english and publish it somewhere.

Hey guys!

For the wheelie control, I spent some time testing some CHEAP options, b/c I didn't want to pay $500 on a freaking Racepak ride height sensor, which is what they use in the US.
So I thought we could use one of the distance sensors we have in the robots I build to play with my son and guess what: the thing f* works!

Of course you have to know how to use the function and configure the sensor, so that's why only a couple guys here in BR (which happens to be friends of mine Smiley ) are successfully using them, even though I have wrote an article for a performance magazine explaining (not in details) how to use the sensor.

The sensor is a SHARP infrared sensor (GP2Y0A02YK) and it's a bit tricky to calibrate its values. You have to attach it to the car in its final position, and then lift the front of the car, inch by inch, check the sensor reading and start building your calibration table for that sensor.

One thing to notice about this sensor is that it isn't a linear sensor and it's reading table might give you wrong values if the sensor is too close to the ground. My experience with this sensor tells me to fix the sensor at a distance of at least 7" from the ground and then you can start your table from there.

So when building your calibration table, the lowest height it'll have is 7". Then you lift the front until you have the sensor at 8" from the ground, you check the reading in V and add an entry of xV - X" in the table and you'll keep doing it until you feel you have a good table.
Keep in mind the max reading for this sensor is a distance of 150cm and that's not a straight reading anymore as soon as you lift the front b/c the sensor isn't pointing straight to the ground anymore. You'll be measuring the height in a straight line, but the max reach of the sensor will still be measured in an angled way. Smiley

After that, when you check the FT display it'll be showing 7" (or whatever is your first calibration value) of reading with the car at ride height.
I like to make it read 0, so I just go to the sensor offset and adjust it to 0 my reading by setting the offset type to "after conversion" and putting the inverse of my first value in the table. So if the first value is 7, my offset is -7, which will give me a reading of 0 at ride height. Smiley

I'm attaching the draft of the article published on that magazine. It's in Portuguese but you can easily throw it in google translator and get the main idea behind the words Smiley

(I know. I wrote too much Smiley )

[ Attachment: You are not allowed to view attachments ] Cool!

For me, I will put the sensor up front on a 7 meter long dragster.
Should work even if I have to make a small support frame to get it up in the air as you describe.
Portugese, no problem.
I can take on me to translate and share here.

Translated a bit roughly and attached the Pictures.
Nice write up Christiano!  Molto Obrigado!

8 USD from China and under 20 USD over the counter in local store here in Sweden.
Once again, really appreciated information.
Test report will come this summer. [ Attachment: You are not allowed to view attachments ]

I got a chance to test this sensor yesterday, had some other issues so no decent passes but did learn the front of car is nearly 3inches higher at about 120mph than at standstill/normal  Shocked This is the Old cab so no aero stuff at all

E90 BMWs with xneons have a unit (box with an input arm attached to suspension)attached in the front wheel well to the suspension components to raise or lower the headlights depending on suspension position, wonder if that could be a cheap and easy option.?

Lots of Cadillacs and a few Lincoln's here in the states also have ride height sensors, used to help control air bag suspension systems. I may grab a few and implement them next winter.

So it reads sideways and/or forwards so cuts power if you are about to hit the wall like they do in the vacuum cleaners they are fitted to!!!!!!  Shocked Grin

THAT is interesting!

I just ordered 2 units from at about USD 12 each.
One more and then I have one for the height and then a left end right mounted up front at the Wheels, would be a nice safety device.
I like your thinking guys!

This is when the "Oh shit" ignition cut activates, as you can see it kills it completely and pass is done but will save your ass if its all going wrong  Wink Shocked Grin

 Smiley  No problem, as you can see cut doesn't need to be this long duration but this was only 2nd pass with it on so I am still figuring it out
