Ok I posted this in another thread but I thought I would start another about the Auto and modding, mainly changing the ECU.

Who here has a Auto GTS-T and has changed there ECU? has anyone tried using a APEXi power FC on there auto Sky's? I know everyone says it can't be done but has someone actually tried?

I got in contact with Wolf regarding there ECU's controlling the auto, anyway this what I got back.

What I asked:

I have a R33 GTS-T Skyline Auto and was wondering if your Version 4 plus plug in can be hooked up to and control the Auto Transmission?

Reply:

We have had people run the Wolf on R33 auto's, we are not controlling the auto trans.  I have not heard back a response about how the auto trans works without ecu control.

Then I replied back:

Thanks for the reply, this is something I'll be keeping my eye on, as far as I knew the Auto needed input signals from the ecu for it to work probably (to change up and down gears etc.) that's why you can't use ecu's like the Power FC.

Reply:

I know of one customer who has used the plug in R33 ECU that we make on an auto R33.  I don't think they have had any problems.  The car does change gear, it was driven from our factory.

Now I'm bloody confused, so if the Wolf3D isn't controlling the Auto then what is? Does it really need to be controlled by the ECU?:confused:

Any body else got any ideas?

there are two computers for the auto one is the main ecu and there is another computer for the auto itself this computer just gets certain info from the main ecu. Thats how i see it just ask a friend or someone who has one to pop it in your car and see what happens

i dont know about skylines.

but on the 4age20 frount cuts i got. there wasnt a second computer for the auto. it was simply the main computer controlled the auto. the reason for this is to help smooth out the changes.

auto and manual frount have different model computers.

That's cool GTS-t VSPEC, thanks heaps.

Just seeying if anybody else has done anything, there seems to be a few people with auto Sky's and I don't think I'm the only person that would like to do something like this.

Craz0 i'm in the same boat. Have done a little bit of research and talked to Dr Drift here in Melb from BMT.

The only think I can think of beside the full house Motech is the E-manage. The only problem with this is that the ignition harness for some reason doesn't response to the auto ecu. Guys at BMT are still working on it to see if they can figure it out. Something to do with signals interference.

I'm not sure if Link comp can take care of the auto ecu but I was told by my mechanic that it can support it. Unichip could also be a possibility.

But at the moment I'm looking at the E-manage as it is the cheapest out of them all.

Yeah there isnt to much after market support for the auto's.

I was just going to get a SAFC II and a AVCR and call it quits at that, but I thought I'd have a look into it before I set my plan down for the auto sky.

I was cheeking out TakaKaira and Buddy Club have a Race spec computer for the auto, click here then use the drop down second from the bottom

craz0: I thought that AT computer from Buddy Club was for modifying the automatic transmission management. EG: Faster shifts, holding gears for longer... Similar to the power button but with more flexibility...

OR, is it similar to the Buddy Club engine management but with extra features for the Auto?

Has anyone tried a Power FC just out of interest? Maybe it works? :D If not, the symptoms may help with diagnosing a solution....

I'm not a 100% sure know you say that:confused:

Well AP Engineering modified the Power FC for the Auto Toyota JZX100's so I'd say it would be pretty much the same to do it for the Skylines, well I think anyway.

I have read up on the Buddy Club on Takakaira and the impression I got the automatic function on it is similar to our POWER button. I think it will hold gear for longer and down shift quicker?!?!

Craz0 I was thinking about the same thing about getting a SAFC2 to adjust the fuel curve and leave it at that. But I still think that the E-manage will be better than the SAFC. The SAFC only have like 12 tuning points whereas the E-manage have alot more than that if tune with a laptop and harness.

If you think about it an SAFC2 at the moment cost around $500 to $700 depending on where you get one and the E-manage cost around $700. After tuning and installation you are only looking at about 100 - 200 bucks difference. For that reason that is why i'm still sticking with the E-manage. And if someone can figure out the ignition problem it will even be a bonus.

If you are thinking about getting the ACVR as well, why not get the E-01?! This way if you have the E-Manage and he E-01 you can boost your Skyline as well be able to tune it (fuel curve) using the E-01.

Go to the Vic forum and there is a tread there on 'What is E-manage'. You can find out more info there.

That's what I would do, but I'm no car mechanic hehe.

I currently have an R33 series 1 auto with the PFC in it. (and have had no problems).

Later this week I am getting a modified auto installed (tighter shifting and higher stall torque converter). I will post next weekend an let you know how it went.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      Mistakes were made, my R34 Story

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
