muzzytt Posted March 30, 2016 Report Share Posted March 30, 2016 (edited) I've just got traction control wired up on my fury. Car is a97 supra vvti .Has the 4 channe abs system. There was 4 wires from the abs feeding into the oem ecu.So I've wired up one front wheel and one rear wheel to digital inputs. When tc is enabled car stalls on movement. I'm out of di to wire up any more wheel sensors..Another issue in being told is that the fury is not going to be perfect for my supra as its limited to 500hz .I wish i knew about the thunder coming out and this issue before upgrading from my vipec v88.Anyway I'll happy to use it to its limits. Unless someone wants to buy the fury off me. I've attached the pcl file. Cheers Edited May 10, 2017 by muzzytt Quote Link to comment Share on other sites More sharing options...
Scott Posted March 31, 2016 Report Share Posted March 31, 2016 Hi muzzytt,Thanks for the base-map. Can you also please record a quick PCLog of the problem?Using one front wheel and one driven wheel will work fine. muzzytt 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 31, 2016 Report Share Posted March 31, 2016 (edited) I just took a quick look over purely your TC settings. RPM lockout, TP low lockout and Speed lockout don't appear to be sensible values to me. I have never set up TC with a G4+ before so I'm stabbing in the dark a little but I would suggest starting with values around 2000RPM, 30%TP & 30Kph and tune from there.Edit: sorry Scott, I see you must have posted as I was typing mine...

muzzytt Posted March 31, 2016 Author Report Share Posted March 31, 2016 Scott I'll do that and get back to you. Adam thanks I'll have a play with that also. Cheers Quote Link to comment Share on other sites More sharing options...
muzzytt Posted April 6, 2016 Author Report Share Posted April 6, 2016 ok stalling was because the lock out settings where too low. thats solved. Im doing the wheel caliobration in the help files it says (Number of Sensor Teeth / Wheel Diameter) * 31.83. Note that wheel diameter is in meters the teeth are 48 the diameter of the wheel is 2014 so im presuming thats 48 teeth x 31.83 which equals 1527 ?

Simon Posted April 6, 2016 Report Share Posted April 6, 2016 That seems like a very big wheel diameter. Quote Link to comment Share on other sites More sharing options...
muzzytt Posted April 7, 2016 Author Report Share Posted April 7, 2016 That seems like a very big wheel diameter.its 2.014m iput the dimensions into the calculator that's what it came up with 2014mm Quote Link to comment Share on other sites More sharing options...
Scott Posted April 7, 2016 Report Share Posted April 7, 2016 I think a mistake has been made, a 2.014m diameter wheel is what you would see on a large truck. Why don't you get a tape measure and just measure the diameter of your wheel including tire? Quote Link to comment Share on other sites More sharing options...
bsh Posted April 7, 2016 Report Share Posted April 7, 2016 I believe diameter of the wheel is about 0,6 m. Quote Link to comment Share on other sites More sharing options...
Simon Posted April 7, 2016 Report Share Posted April 7, 2016 Given you have a tooth count of 48 I suspect the frequency is going to get to high for the digital input.The input can only reach 500HzRoughly you will reach this frequency at 125kmh (Given a wheel of 0.6m diameter) Quote Link to comment Share on other sites More sharing options...
muzzytt Posted April 8, 2016 Author Report Share Posted April 8, 2016 Thanks for the input appreciated. Simon if i can get tc to work to 125kmh I'll be content with that. So we measure as in the picture above straight across ? Cheers Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 8, 2016 Report Share Posted April 8, 2016 So we measure as in the picture above straight across ?Perhaps the definition of diameter will help?: muzzytt 1 Quote Link to comment Share on other sites More sharing options...
muzzytt Posted April 8, 2016 Author Report Share Posted April 8, 2016 Ok 0.67 and 0.65 is what I've got My bad was looking at circumference instead. Quote Link to comment Share on other sites More sharing options...
Scott Posted April 8, 2016 Report Share Posted April 8, 2016 (edited) Ok 0.67 and 0.65 is what I've got So calibration numbers of 2280 and 2351 should work for you.Because of the 500Hz max input on the digital input channels I think your traction control is going to be a little less than Simon estimated.500 Hz / 48 teeth = 10.4167 wheel revolutions per seconds.For your wheel with 0.67 diameter you have a circumference of 2.04m, so you can do up to 21.2501 meters per second (10.4167*2.04), which is 76.5 km/hFor your wheel with 0.65 diameter you have a circumference of 2.10m, so you can do up to 21.2501 meters per second (10.4167*2.10), which is 78.8 km/hKeep an eye on the ECU when getting above this speed. Ideally you would want to reduce the amount of teeth. Edited April 8, 2016 by Scott Quote Link to comment Share on other sites More sharing options...
muzzytt Posted April 8, 2016 Author Report Share Posted April 8, 2016 Scott Not great news at all. Sounds like i should just can the idea. As it seems the system was only designed to be run with a specific number of teeth. Either that or i have to sell this and go the thunder which i sort of can't be stuffed going through another wire job etc. Was really hoping that when i upgraded from the v88 this would be the ultimate for my setup turns out its not. Thanks for your help anywayMuz Quote Link to comment Share on other sites More sharing options...
Scott Posted April 8, 2016 Report Share Posted April 8, 2016 Hi Muz,Are the wheel discs band sensors still being used for ABS? If not then one option would be to chop 2 out of every teeth off the wheel. This would then bring you down to 16 teeth, which means you could go 3 times higher in your wheel speeds.

Adamw Posted April 8, 2016 Report Share Posted April 8, 2016 Also, you could use a frequency divider. Something like this would do it without breaking the bank and should still allow ABS to work (will need one for front and one for rear):https://shop.vems.hu/catalog/hall-p-162.html Quote Link to comment Share on other sites More sharing options...

Scott Posted April 11, 2016 Report Share Posted April 11, 2016 Yes, you will need at least two for traction control (one on a driven wheel, another on a non-driven wheel. It looks like the device can divide down by 2, 4, or 8 (default).If you divide down by 8 the digital input should be able to get up to 600 km or so. muzzytt 1 Quote Link to comment Share on other sites More sharing options...

muzzytt Posted May 10, 2017 Author Report Share Posted May 10, 2017 All I've wired in signal splitters to reduce the teeth count from 48 to 12So I've divided it down by 4. I've also changed wheel diameters. Front 61Rear 62.5I need to work out the values I need to input into the software. Would appreciate some help here as I'm wanting to do some testing on it and maybe get it working for the nulon nationals at Bathurst this weekend. Cheers in advance TechDave 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 10, 2017 Report Share Posted May 10, 2017 Try calibration numbers 626 for the front and 611 for the rear. Quote Link to comment Share on other sites More sharing options...
