Wolf3d Ver4 in a GTT Auto

[SnRuB]

Hi all,

Ive been reading about fitting an aftermarket ECU to autos and searched the forums and the best thing i could get was a daugtherboard, which hasnt been made yet.

I had a chat with someone from Wolfems (i know his name but wont mention it) and he said that i could fit the Wolf 4 in a piggy back setup so my ECU will still control Idle and shifting but the wolf would do the rest that i require.

Can anyone out there tell me if this has been done to their cars and just your general thoughts. I definitly cant go 5speed (the wife :bs!: .)

Thanks

Ben

I know that config has been used on turbo charged Falcons so it can work, with a skyline I don't know.

hi

there are a few options for GTT autos (in no particular order)

1) Remap from a workshop (e.g. powerplay)

2) Daughterboard

3) E-manage

4) Unichip

5) SAFC I/II

theres a member here who has a unichip in his r34 and currently has around 200~ atw

i'm getting one installed in mine soon as well

Hi Ben, if you use the Wolf to run the ignition then you won't get igntion cut on gearchanges. This will adversely effect the shift quality and cause premature wear of the gearbox. The standard ECU has extensive programming for this purpose. You could just use the Wolf to run the injection, but an SAFC or equivalent would do almost as good a job for less than 1/3 the cost.

PS; there has been lots of discussion on this topic, I strongly suggest you do a search.

Thanks for that. I did do a search and read most of the info about shifting etc and found that the main one was the daughter board. Heres the email i received back from Wolf;

"Hi Ben,

The only way to put a system on that car, would be to piggyback

the Wolf3D Version 4 ECU (leaving the original in place), and the original

ECU would then control idle, auto trans shifting, etc, and the Wolf would

do ignition and injection, and any other auxiliary functions that you

require."

I guess what i should have asked in the first place is, what advangates would a Wolf in this configuration offer me, for future modifications and just general tuning.

The safc2 is approx $400 and daughterboard is expected between $600 and $800.

Thanks

Unfortunately Ben you have to know what questions to ask, and that is sometimes not so easy. Stuff like "the original ECU would then control .....auto trans shifting" seems to indicate the the auto would work normally. But it doesn't, because of the reasons you now know.

I get a lot from reading the posts on SAU, not all of it is answers. Sometimes I find out the questions I need to ask.

[SnRuB]

Thanks once again. Its a while off yet before i get this stuff done, but it will give me chance to find that question... I guess its like the answer 42... Whats the question :-) ("The Guide")

I will do a bit more asking and see if i can get a guaranteed "wont f**k your shifting, if we fit it for you".

Cheers,

Ben

Not sure if this is who you spoke to, but i will ask this question to Steve at AEM, the brains behind the the WOLF3D ecu, and see what he says.

Thats him. Steve Taylor. Thanks Al

The WOLF can be setup for an external ignition trim, on one of the inputs.

If you can arrange for, or have a switched signal, (digital for preferance) that can trigger this event in the WOLF on gear changes, then it should be do-able.

The WOLF trim table seems to be able to reduce timing as required for this kind of application, but I have not read of anyone trying it!

Alternatively, you could force a momentry change to the air temp sensor reading, by having the gear change 'switch' bridge a resistor across the sensor.

Then setup the air temp ignition modifyer table to dump timing on gear changes.

Spoke to my mechanic/tuner (could not get in touch with Steve), he stated that the wolf may not be able to cut ignition on gear changes, but he has never tried hooking a wolf on a R34 auto. On the other hand, he also stated that a mod can be done to the box to overcome this issue. He told me what part required modding/changing but i forgot as i asked him about a week ago.

skyquest's suggestions sound fesable, may pay to e-mail Steve with this idea.

All the best
