rider Posted January 18, 2017 Share Posted January 18, 2017 I checked Japanese availability within the last 2 weeks on all four sensors and only one came back as still available and three are out of stock with no schedule to restock. Effectively out of production. Lots of sites still list a price for all four sensors but then will come back as not currently available.

Scooter Posted January 18, 2017 Share Posted January 18, 2017 You wonder if a GS300 or Soarer part might do it. They seem to come with brackets etc to fix the wire, but if you reused the Supra ones the actual sensor and wiring may be the same http://www.rockauto.com/en/catalog/toyota,1994,supra,3.0l+l6,1278615,brake/wheel+hub,abs+wheel+speed+sensor,1912 Quote Link to comment Share on other sites More sharing options...
mugen_power Posted January 18, 2017 Share Posted January 18, 2017 Lexus ones do fit, I'm using them on the front, identical part number however the rears don't unfortunately Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted January 18, 2017 Share Posted January 18, 2017 Has anyone swapped over to digital hall sensors? http://codyphillipsracing.com/store/store/cp-racing-cnc-wheel-speed-bracket-digital-hall-sensor-front/ Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted January 19, 2017 Share Posted January 19, 2017 I'm trying to work out if installing the ABS hall sensors would be a straight forward job. I'm running a Syvecs and according to this post by Chris Wilson it would appear that the syvecs can use a digital signal to control the ABS system. http://www.mkivsupra.net/vbb/showthread.php?316889-Traction-Control-and-ABS-analogue-to-digital-converters&highlight=Hall+sensor My questions are, assuming the Syvecs can utilise the hall digital signal from uprated sensors: Is there a stand alone ABS ECU, or does the main ECU drive the whole system? If there is a separate ABS ECU, does it take its signals direct from the wheel speed sensors or via the main ECU? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 19, 2017 Share Posted January 19, 2017 (edited) Does the Syvecs have the ability to run ABS? I suspect not.... Or do you mean traction control? Most after market ECU's expect a digital signal to run traction control, so you either run magnetic sensors and digitize their sine wave to a square wave, or run Hall effect sensor which emit a square wave natively. The only aftermarket ABS ECU I have any experience of is the Bosch Motorsport one, which is breathtakingly good, but also breathtakingly expensive at £7K Sterling. http://www.bosch-motorsport.de/de/de/produkte/catalog_products_1_772244.php Edited January 19, 2017 by Chris Wilson (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 19, 2017 Share Posted January 19, 2017 Seems Bosch now do a cheaper version for club racers, but still the best part of 5K Sterling. http://www.racedatasystems.com/bosch-abs-m4-clubsport-motorsport-abs-clubsport.html Quote Link to comment Share on other sites More sharing options...

Jellybean Posted January 19, 2017 Share Posted January 19, 2017 Motec M1 has the ability to run Bosch ABS M4 systems, for the Supra package the ECU taps into the ABS ECU for Wheel speeds (Traction Control) Quote Link to comment Share on other sites More sharing options...
Sheefa Posted January 19, 2017 Share Posted January 19, 2017 The Syvecs uses the stock abs sensors, so presumably it processes the and signals, but as far as I'm aware it retains the stock abs ecu. Yep. TC ran fine with my Syvecs on stock ABS sensors a while back, albeit something has gone amiss since the upgrades which I need to datalog with Lee.

mwilkinson Posted January 19, 2017 Share Posted January 19, 2017 Sorry guys that's probably a lack of understanding from me ref traction control and ABS. I see that in using the hall sensors that the ABS has to be dropped as there is no way (cost effective way) of converting the signal to an analogue one that the ABS ECU could use. I was hoping this may have been a way round the imminent loss of Supra ABS sensor supply. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 19, 2017 Share Posted January 19, 2017 Well if the Syvecs has sufficient analogue inputs you can run the stock magnetic sensors, and they can be used for TC, which both seem to be the case, you shouldn't need to touch the stock ABS.

mwilkinson Posted November 21, 2017 Share Posted November 21, 2017 I've just ordered two new rear ABS sensors from Amayama. They have now been posted so I'm actually going to get something, as to whether or not it's the parts I'm expecting is another matter. Out of interest I think the confusion over the ABS sensor availability seems to be with regards to pre facelift and facelift part numbers. The only difference being the bracket changing from metal to plastic (if I got my info right from Barry's thread (rider). The part numbers I uses were: 89545-14020 Rear RH 89546-14020 Rear LH I'll update once I receive the items. These cost £360, less VAT and duty.

rider Posted November 21, 2017 Share Posted November 21, 2017 On the hubs off the facelift frame I used for the swap the ABS sensors looked to be bigger (as in wider) than the ones on my pre-facelift hubs. If it does turn out to be a wider sensor then next thing to look at would be the pickup ring on the drive shafts. If that is the same pre to post facelift then you'd imagine that the sensor housing could be machined to accommodate a larger sensor.

I can only find a single part number for a rear hub running from 1993 to 2002 for Jap Spec with ABS. You would think there would be a variance in the part number of the hub if this was the case?

blythmrk Posted November 21, 2017 Share Posted November 21, 2017 Thanks for your reply Pal!

I don't think that an unreasonable concern given the cost of the parts. Edited November 21, 2017 by mwilkinson (see edit history) Quote Link to comment Share on other sites More sharing options...
