AndrewOW Posted January 18, 2012 Author Share Posted January 18, 2012 There are approximately 20 pins on the ECU plug, and the module only uses 5 of them, so getting something switchable would mean a whole different approach, and this one just gives the user a basic Up/controlled Down, rather than speed related auto additions too. The ECU has all kinds of extra things going on, and finding out what bit does what would take someone with a lot of experience. Garfy managed to get the module working in that form, and it works great IMO. Quote Link to comment Share on other sites More sharing options...
neilp9876 Posted January 18, 2012 Share Posted January 18, 2012 I dont know how the garfy version works but it would be amazing if we could get a version that was switchable. I found some circuit diagrams on the net of the ECU, one of them even has the manual control. http://homepage.ntlworld.com/peter.betts/supra/TechTips/spoiler1.htm I know Heckler talked about making one of these controls a while back, is the there no way a few electronic geniuses could put their heads together and work out how to make one?

AndrewOW Posted January 18, 2012 Author Share Posted January 18, 2012 I'm sure it can be done, as temporarily bypassing the ECU in manual mode I'm sure is possible, but it would take someone cleverer than me to do it. No one else has attempted it in all these years. Quote Link to comment Share on other sites More sharing options...
Burna Posted January 18, 2012 Share Posted January 18, 2012 Heckler was once interested in buying the Blitz AS-C that was for sale on here once to copy it, he didn't buy it the end though Quote Link to comment Share on other sites More sharing options...
neilp9876 Posted January 18, 2012 Share Posted January 18, 2012 Another thought ... Do the UK Spec work differently do the J Spec spoilers. My J Spec will not manually lower the spoiler unless the engine is off, whereas Josh seems to believe that he can lower his spoiler at will, also this page seems to agree with Josh : http://homepage.ntlworld.com/peter.betts/supra/TechTips/spoiler1.gif If a UK Spec can lower the spoiler at will, then that would be fine for me, the question then would be is it the ECU thats different or the wiring between J and UK spec's?

AndrewOW Posted January 18, 2012 Author Share Posted January 18, 2012 Heckler was once interested in buying the Blitz AS-C that was for sale on here once to copy it, he didn't buy it the end though By the looks of it, the Blitz AS-C did exactly what Garfy's one does. Makes the spoiler fully manual, as it just has a better plug than Garfy's. I don't think it was auto/switchable, but I'm still looking in to it. Another thought ...

I don't think there is any difference to either, as Garfy had sold to UK owners as well as JSpec owners. My JSpec still has the original prototype in it, as mine was the guinea pig for it.

If you meant me, I can only put mine down if the ignition is on. When I turn the engine on, it goes back up and won't come down until the required speed is reached. If you ever see my car parked, it will always be down Quote Link to comment Share on other sites More sharing options...

neilp9876 Posted January 18, 2012 Share Posted January 18, 2012 How does the ECU know the engine is running? If we can turn that signal wire to always read off then wouldn't the ECU think the car was parked and allow the spoiler to come down.

AndrewOW Posted January 18, 2012 Author Share Posted January 18, 2012 (edited) All I know is, Garfy tried a few things, but the ECU is programmed to respond to speed. It all seems simple in theory, but I assume he tried that. I remember him telling me it was a nightmare to get it to work unless he bypassed it completely.

AndrewOW Posted January 18, 2012 Author Share Posted January 18, 2012 Fair enough. Driving around town with the spoiler down really does create a very aggressive look, and as I can control it, it's the best of both worlds. Leave it Up if you only want to bring it down on the motorway, etc. Quote Link to comment Share on other sites More sharing options...
AndrewOW Posted January 18, 2012 Author Share Posted January 18, 2012 I've just found out, from someone that used to have a Blitz AS-C, that it converted the active spoiler to fully manual, and not switchable between auto/manual, etc. Quote Link to comment Share on other sites More sharing options...

Maybe the chap I spoke to didn't realise it goes back to automatic when the Auto/Off button is pressed? I would only assume that's how the Blitz controller works.

neilp9876 Posted January 19, 2012 Share Posted January 19, 2012 So who's got a blitz controller that we can clone? Quote Link to comment Share on other sites More sharing options...
AndrewOW Posted January 19, 2012 Author Share Posted January 19, 2012 I'd imagine that inside the Blitz controller is a printed circuit board, so not quite a simple cloning as you may think. Quote Link to comment Share on other sites More sharing options...

Slicknick Posted January 26, 2012 Share Posted January 26, 2012 I've got the Blitz one and can confirm it's not switchable. I have the blitz one and it is switchable, locks down or goes back into auto. Quote Link to comment Share on other sites More sharing options...
ellis Posted January 28, 2012 Share Posted January 28, 2012 Just fitted mine this morning - works a treat! Good instructions, nice colour coding on the wires and easy to follow and if a technoprat like me can fit it, the rest of you can! Good work Andrew - spot on mate!
