RobEvans Posted July 22, 2007 Share Posted July 22, 2007 Iv bought a second hand HKS SLD spec 2 from a member of this club with no instructions. Iv just fitted it (see below) and took it out for a test run, reached over 70mph and the red triangle lit up along with the engine management light also STILL LIMITED! Iv searched the forum for infomation on fitting this item and I have found very little apart from ECU pin outs from Nic. Its a 1993 Jspec auto... I connected the yellow wire to the speed sensor, ECU side (pin 2) the white to the speed sensor loom side (pin 2) the black to earth the red to 12v (pin 31) Theres a buch of wires left over but cant find any info on connecting these. Will someone please help me as im getting realy pissed now! Cheers Link to comment Share on other sites More sharing options...
stevie_b Posted July 22, 2007 Share Posted July 22, 2007 Probably not much help but.... I've never seen the HKS SLD but I've fitted the Thor one myself. I can't imagine they're that different. What code is logged? I bet it's code 42. If so, that would mean that in the process of fitting the SLD you've interrupted the speed signal that goes from the speed sensor, via the speedo dial and odometer (and possibly other goodies) to the ECU in the passenger footwell. Someone else may be along shortly who knows the HKS better than me... Link to comment Share on other sites More sharing options...
RobEvans Posted July 22, 2007 Author Share Posted July 22, 2007 Do you know what wires you connected to on the ECU?? just so I can check them. I used pin 31 (+B EFI main relay) as a 12V source, same as the FCD. Maybe this is wrong? Would be the same id have thought as other SLDs. thanks mate Link to comment Share on other sites More sharing options...
stevie_b Posted July 22, 2007 Share Posted July 22, 2007 Note sure. Have a look at this: http://www.mkivsupra.net/vbb/showpost.php?p=988347&postcount=35 It talks about DSC rather than the SLD, but they are very similar devices. My combined DSC+SLD took 12v from behind the dashboard, but it looks like pin 2 on the ECU plug is the speed signal that needs to be clamped or limited.

RobEvans Posted July 22, 2007 Author Share Posted July 22, 2007 the error code is 2 blinks followed by 4 blinks with the O/D light flashing... Please help! Link to comment Share on other sites More sharing options...
bondango Posted July 22, 2007 Share Posted July 22, 2007 On the Type 2 theres also a wire for the RPM, and IIRC theres 2 wires that go to the Autobox ECU. I had the install somewhere, will see if i can find it. Link to comment Share on other sites More sharing options...
RobEvans Posted July 22, 2007 Author Share Posted July 22, 2007 Please mate if you dont mind, i dont get online much.

flukey-lukey Posted July 22, 2007 Share Posted July 22, 2007 I have one of these and it didn't work. I decided to take the kph to mph convertor off the back of the speedo unit to see if this was affecting it, it was So now I'm reading in kph again, but no speed cut Link to comment Share on other sites More sharing options...
stevie_b Posted July 22, 2007 Share Posted July 22, 2007 the error code is 2 blinks followed by 4 blinks with the O/D light flashing... Please help! Are you sure it's not 4 then 2, instead of 2 then 4? Watch out for the long pause which (if I remember correctly) denotes the start of the number. Thor SLDs used to be very good: not sure if they make them anymore though. If you don't get any definitive instructions on how to wire the HKS one, start a new thread to ask members which SLD they recommend. Code 42 error is often caused by a faulty speed converter or SLD, or one that's been incorrectly wired. Link to comment Share on other sites More sharing options...
RobEvans Posted July 23, 2007 Author Share Posted July 23, 2007 Yep on second check it is code 42. so maybe its because the cars converted to mph already. Where would the km/mph converter be? there seems to be nothing wired into the ODO or the dials, the dials read to 180mph and seem to be UK ones. I wonder if id still have the same problem with a thor one? Has anyone done this? GUTTED! Link to comment Share on other sites More sharing options...
stevie_b Posted July 23, 2007 Share Posted July 23, 2007 The speed converter should be either behind the dash clocks, or behind the odometer. If you didn't have a problem before fitting the HKS SLD, then the problem is unlikely to be your speed converter. You could try removing the SLD and see if the problem is still there. When SLDs or speed converters are wired correctly, they shouldn't give rise to engine management warnings. At worst, all you should have is overly-light steering, which is due to how the speed signal gets limited and/or converted. The better ones eliminate this too.

Chris Wilson Posted July 23, 2007 Share Posted July 23, 2007 Some early converters were under the car, above the gearbox, in the transmission tunnel. These get wet and eventually fail, or have bizarre problems, look there. Link to comment Share on other sites More sharing options...
bondango Posted July 23, 2007 Share Posted July 23, 2007 Unless he is running UK clocks in which case there wont be an electronic kph/mph speed converter I Cant find these SLD II instructions at the minute, the only one we fit to the Supras and Soarers is the SLD Type T6 (14 wires!!) as this keeps cruise control etc etc and is the only one recommended for Toyota Autos. There have been numerous problems with People running the SLD II on Autos, no probs the the SLD 1 on manuals though. TBH, i would think about either a T6 or the Thor unit. I know there are wires on the SLD II that must be connected in order for it to work, 1 being the RPM, and two others to the Cruise ECU IIRC. I'l continue my hunt for the destructions..

RobEvans Posted July 26, 2007 Author Share Posted July 26, 2007 Hi bondango any luck? My cars got UK clocks i think 180mph... Thanks guys Link to comment Share on other sites More sharing options...
bondango Posted July 27, 2007 Share Posted July 27, 2007 Sorry Rob cant find it, But here the Info for the SLD T6 if you ever decide on 1, this is the SLD we fit to JZS147 Aristo's and Supra TT Automatics as it keeps Trac and cruise functioning etc etc http://supras-ireland.net/files/HKS_SLD_T6.pdf Link to comment Share on other sites More sharing options...
RobEvans Posted July 31, 2007 Author Share Posted July 31, 2007 thanks for trying mate. Anyone know if i can i use those instructions with my unit? Link to comment Share on other sites More sharing options...
