I'm wondering if there's anyone here that has had an auto-sparky hook up a full "standalone" ecu into their r32 GTS4 or GTR and how much they payed (Older style link in my case).. I had my ECU installed about a year ago and the 4WD was never hooked up so now it only works in 2wd. The attessa ecu is telling me there is a problem with the TPS ie no thottle signal to it.

At the time I spent 1000 NZD to get it installed, now I've just got off the phone with the same guy who's been looking at the car this morning and he's telling me its gonna cost another 400-500 to get it working. I'm not happy, this should have been installed the first time.. I thought the 4wd worked because I had no 4wd warning light, It wasnt until I went to the drags and had my friend look at the front wheels while I had it on some grass to check, and they weren't moving.

Is it much harder to install an aftermarket ecu to a 4wd? or is my auto-sparky a complete rip job? thanks in advance.

it would may more come down to the ecu used. the ecu may not be suitable for using with the 4wd setup as it may not send the signals on, but i don't know for sure. had you gone a straight plug and play setup such as a pfc then i don't think you would've had any issues. was the $1000 the cost of just wiring it in, or did it also include the cost of the unit as well? if it was just to get installed then you got ripped.

I found - too late - that the unit to use is the GT-R if you are doing PnP.

Advanced Engine Management (www.wolfems.com.au) have a "black box" solution, for a lot less than $500.

Nope that was just the cost of wiring it in, I picked the wrong ecu and the wrong auto sparky. Not enough research on my part but I'm over it now and would like the 4wd working before I sell it.

only things that you have to worry about are

: tps signal to atessa spliced into the tps sensor wire.

rpm signal to attessa spliced into tacho out

speed signal wire to attessa spliced into loom near ecu.

with a rb26 ecu pinout diagram its a 5 min job with a pair of side cutters and a soldering iron :thumbsup:

the rest is a straight forward wire up..

yes thanks T04GTR I've just had it looked at by another guy this morning and those signals are the same ones he mentioned to me .. aswell as the "gearbox sensor" needs to be connected, not sure what that does or if its necessary..

T04GTR - this "speed signal wire" I assume you are talking about PIN 53 on the ECCS "Vehicle speed sensor" what pin is this connected to on the attessa ecu? I'm looking at CH-66 in the manual and cant see it?

All the other ones I've found, thanks again.

i dont have it on hand, but you need to basicly snip it from the oe ecu plug and splice it into the new loom.

in the factory ecu the signals mentioned above go into the ecu and back out via a differant pin. all that needs to be done is these signal wires going FROM the ecu to the attessa to be cut and joined into the INPUT pin on the ecu so there is no "relaying" of signals.

ive had to do this mod for power fc's as some of them "loose" the output for tps some how..

      You are perhaps suggesting that it is not a super car? Well....it's not an AU.

      Dropped the MX5 of this morning to get the hardtop colour matched and some PDR done, they are also going to give it a buff to remove some "stubborn" swirl marks and light scratches in the clear coat Over the last few months the poor little thing has copped some shopping centre car park abuse, I try to not park in them, but hitting Westfield's a few times over the last few months has taken its toll, nothing really bad, but enough of a trigger for a "while we're in there" thingie  Once it's back and all the one colour, with a few dents and mark's removed I'll give some of these products a go and see what they're like

      A locally delivered Infiniti have remote start installed but don't come with the remote start key. You need a new remote start key and they just need it programed. And this is different to making/programing a new key that just starts the car.

      Cheers, and cheers for sharing so much of the build and also sharing the glimpse of what turns out to bring a lot of us poor decision makers together haha.  I do recommend learning more about how to manage it, if not considering getting a  formal diagnosis.  The discussion with the psychiatrist I got my diagnosis through was quite eye opening, things I'd not even considered to be ADHD related and hadn't mentioned were things she asked about out of the blue and were common themes with people with my flavour of ADHD.   It's not a label for people who are hyperactive and ill-attentive, there's more to it than that and some of it can be much more challenging or damaging - though there are of course two sides to the thing, and a lot of the stuff we have to go through and work on to live with it make us effectively "better" at other things as well. Aside from the fact that there is some argument I could have a bit of ASD seasoning in there (came up during the diagnosis, and neurodiverse things seem to not stay as a cookie cut) I suspect you need to learn more about ADHD if you are puzzled about how hyperfocus could possibly apply.  I *do* personally use "superpower" with quotes deliberately, but it's 100% an ADHD thing due to the exact reason that lack of focus is also an ADHD thing... Loosely speaking the inattentive side of ADHD isn't the inability to focus, it's the inability to control where the focus goes.  Not being able to sleep because brain is more interested in thinking about a stupid thing I said to a girl I liked 30 years ago, not being able to focus on work because my brain is more keen on putting together the torque management strategy we're going to try out with a drag car next weekend, not being able to focus on a conversation with someone I WANT to listen to and respect because there is a flickering light in my peripheral vision.    If I could just stop work and build the torque management setup right there and then I'd not hear anything else until it was done.
