Found this. Looks like that signal is the opposite of what we want. Bummer 'cause that would have made it pretty easy.

How old was that post Craig? You gotta get out more...

I gave up on the anti lag, it didn't help much as the stally has been returned to a stock stator, and there is no possibility of it ever making boost. Yours would be a different story. I had plans to test another method to pre spool the turbo, compressed air, but this isn't the car to test that theory on. lol.

I can see mine going rwd manual very soon anyway which gets right around the launch issue. Or perhaps I will drop back to a highflow again for launch boosts, and so the gearbox isn't having quite so hard a time.

Anyway, back on topic, the neutral signal will work one way or another, but if it's 12v then it will be a simple strip and twist, nice and easy for a DIY with pics. I will take some shots when I test this out on the next car. (Damn Leon, you beat me to it. Looks like we will need a relay.)

Relay will probably work as 0V is normally an earth, but sometimes it is just 0V.

But all is not lost for a dead simple solution. Why not use the Start signal on Pin 42? According to my research, that wire has 9-12V when key in start position & 0V otherwise. Sounds perfect, yes?

DIY instructions:

1) Cut wire on Pin55 a few inches from the ECU connector. Strip ECU end & tape up other end.

2) Strip small amount of insulation from wire on Pin42 (leaving wire intact).

3) Solder Pin55 wire (ECU side) onto Pin42 wire & tape up.

Job done :thumbsup:

Testing & pics are all yours Scotty. I'm not moving mine from where it is as works just fine, but the above is certainly an easier solution....if it performs as expected.

so has this been tried and tested yet??

would i need to install a diod if i went this option

If you don't want to install a 'valet' switch then you don't need a diode when you connect any 12V source, be it from reverse lights, another pin on the ECU or anywhere else.

Ideally a 12V source close to ECU is best. Just need one that is 12V only at times when you don't need full throttle; eg reversing or starting the car.

The only location for reverse lights that I have found is at the rear, so not very convenient (although I already had a spare wire left over from TV install) & the start signal on the ECU is certainly convenient, but Scotty thinks it may not be active long enough to keep the code clear (although I think it should be OK 'cause when mine put out a CEL it would only take a few seconds with the switch thrown & pedal pushed to clear it).

Why don't you give it a go & let us know? If you do the mod you should know in 500km or so. Cutting one wire & joining it to another seems to be the simplest idea we've come up with so far.

Because it will have looked for the brake wire signal & generally spotted a fault in that time.

Mine sometimes goes weeks without throwing the fault; so it can be a bit hit & miss.

Mine takes about 5 seconds to reset. Still worth trying it, as a quick supply of power might be enough to stop the light from coming on, instead of the few seconds to override the light.

One thing I have noticed is I get better fuel consumption with the light on.

You will.....it will go lean.

    • Sorry to hear your HFM BM57 was faulty,  did you contact HFM I would hope they would be at least grateful for the information if there was some sort of manufacturing fault, you would hope they would be sympathetic even if your item was 2 years old if it had never been fitted. May I ask where it leaked from ?
    • Cats are called Bella, and Donna...  Like that poisonous plant And I remember your 2 monsters, I remember making a little bit of wee when you let them out... LOL I have already installed cat doors into the laundry where their kitty litter is, and the sun room, apart from the cat doors there's not going to be any permanent mounted stuff on the interior walls (interior doors are cheap and easy to replace) I will get a outdoor cat cage thingie once I finish the landscaping out back... https://catnip.com.au/ The only off limit areas are the main bedroom and the gym room....but, currently the cats are curled up in bed, in the main bedroom with the Mrs.....LOL, the off limits for the kittens to the main bedroom lasted about 5 minutes with Jackie I currently only have 1 free standing huge cat tree multiple level scratching post thingie in the lounge room, but, I will be getting another one soon now that I'm happy with the furniture layout in the back room and have a perfect spot for it  
    • All of this is making it seem clear that running the Coppermix twin was definitely the way to go, especially in hindsight with how insane tariffs have gotten and the strength of the USD vs yen at the time.
    • That sounds like no chance of even importing one for road registering then Now I see why Duncan wants to check LHD rules for Targa...   I wonder how "bolt in" the AWD would be if you got one imported from the US and swapped it to an AUD one
    • Not to mention they drive like a bucket of bolts! yuck!
