You are correct!

I just played around with it myself and it shows the same error. A workaround is to just create your own Generic and apply ignition correct (as in take timing out) when there's a GPS Speed / Drive Train speed difference.

I'll end up trying this out one day as I want traction control.

Your right foot is variable you know, it's not a switch

Computer can do it better then any foot ever will

Fwiw any time I've heard of or been involved with using GPS for this kind of thing it's turned out that GPS latency is too bad even it's fast.  Remember the GPS speed is a "in hindsight" measurement, so it basically checks how long it took to cover ground and works out the average speed required to take that long... Which means you'll be going faster than what you've got from the GPS setup.   The results I've seen are as you'd expect, basically it cuts the wrong amount and too late - could argue that the tuning could be tweaked for it but you are actually trying to make decisions based off things which have already happened which is going to be flawed.

With 4wds I think accelerometers or predefined torque profiles for the situation are the less problematic way to go about things like this depending on how precise you want to be.

Yep, and wheel speed sensors. This can be made simpler if you are running out of inputs (4xdig inputs required) by running the Bosch Motorsport ABS which will transmit your wheel speeds over CAN. The bad news is you need to convert the rear ABS sensors to work on the hub end of the driveshaft because it's quite fussy about drive shaft wind up. That and the cost of course.....

I'm not familiar with Haltech but from what I've heard they also do a version of torque management which is similar and simpler to setup than the M150 Pro package. Seems to work in drag cars ok.

that mess will run the car eventually

I’m officially back to where I was 5 months ago lol

Wiring, such a joyous part of every build!  She must be getting pretty close now?  It’s at this point I generally decide it’s time to add something else and completely undo everything I’ve done to get to this point…..

That was what I did to get back to this point lol. I think I’ve added everything I can add and now it’s just full steam a head

Oh you'll find something to put it back another month or two!!

Started getting the wiring inside the car routed and connected and also putting the interior back together. 
 

I decided to fit a key pad to control things like boost level, rolling anti lag and launch control on/off, there will probably be other things I’ll find for the other buttons 

the interior is now looking more complete then it has in a long time and the gear position, strain gauge and eboost2 now work, I also connected the reverse lights through the pdm and they work when required. The pdm and ecu are both mounted and the can cables are connected back to the ecu 

[r32-25t]

After spending 3 weeks in Japan I finally came home and got to play with the gtr again, today I wired the 3 pedals to the ecu, wired the power steering pump and set up the over ride button. Also put all the carpet back in place. Finally ready to start putting seats and etc back in

Fancy!

Japan would have been amazing!  I presume you got to do some car stuff?

Japan was awesome, such a beautiful country. I went to the Nissan heritage collection. I rented an sti and drove the skyline road in hakone with it which was a lot of fun. Did the usual up garage visit and nismo omori visit as well. Apart from that it was a lot of site seeing and taking in the history of japan

Sounds amazing!  I need to pull my finger out and get there before I get too old and cranky to be effed doing anything!  Just need to convince the wife it won't be ALL car related stuff....  Or go without her of course!

Now, get back to work, you've got a GT-R to finish off and inspire the rest of us (ie me!).

[r32-25t]

It’s getting there, since getting back I’ve spent every minute on it I can 

[r32-25t]

more genuine parts, these hold the base of the rear seat in and due to the seat having come out so many times the old one were pretty ordinary. 
 

and the rear seat is in and it’s really starting to look like a car again 

[r32-25t]

Due to the fact I’m still running the original dash I thought better add something that quickly tells me the information the ecu has available 

I replaced the boost gauge with a haltech can gauge and found a pod that fits it. The readings are all over the place at the moment because the engine bay wiring still isn’t done 

 

[Old man 32 GTR]

The Haltech CAN gauges are nice, I contemplated installing one when I was running the 3 x centre console gauges. 
but the motec dash kind of eliminates the need for them.
looking good, it’s a good feeling when it’s going back together

I love your dash and if I could convince the mrs to let me spend the money I’d have one without a second thought

Billet blocks, sequential boxes and god knows whatever else, a dash is Fark all 🤣
