2G blue wire mod

[HighPSI TSi Guy]

An automatic is going to shift faster than any manual. You can manually choose what gear to be in, so I'd say an automatic transmission shifted manually would be better than a manual gearbox.

If it were a paddle shifted direct drive trans that would be idea, but it is not. In a low torque situation such as a turbo 2.0 you will not be able to obtain the power curve and response with the gearing, and the converter flash will screw you. The auto shifts fast but it's a different kind of shift than a manual trans. You will need to keep the RPMs way up in the tighter range of the converter to keep the response up, it will not have the throttle response of the manual trans, not even close, due to the nature of a torque converter.

It really will depend on the course and your build. If you're constantly above 35ish mph with a small turbo you'd be slamming between 1st and 2nd gear going through the course and it may work ok, but if the mph drops below that you're gonna bog down real bad. If you have a 2.3 that'd help a ton too. With a 2.3 and a loose converter you might not do too bad.

Bender, I need you (no h0m0)

I need your input to help figure out how to control my tc with my overdrive switch...

I assume you mean TCC? trigger a relay with the OD wire and have the relay supply 12v to the TCC.

HighPSI TSi Guy - The plan is to use a 2.4L with a HX40 in a .55AR housing.
What's all this paddle shift direct drive? Sounds awesome..

I am wondering if he is talking about an smg....

 

[Bender]

Paddle shift direct drive transmissions are expensive for the cars they fit in, and probably won't even fit in a dsm without spending $100,000. I don't even think I know of one with our engine orientation, so you would probably need to flip the engine around so the timing belt is on the passenger side.

definitiveno, you can always email me at [email protected]

Also, Dave is right about the converter. Another thing to try too would be to lock the tcc (with a relay triggered by the OD switch or another toggle). Opposite idea of having a loose converter, but the car will behave more like a 5 speed.

And yes, I actually have quite a few hidden pages on my site.

 

[definitiveno]

Thanks guys. The plan is to operate the TC with OD switch and relocate OD to the dash/console with a toggle. As for the OD, do I just extend the current control wires to the dash? I'm thinking just a simple up/down on/off toggle...... Will I need to add any thing or is it a simple extension of the old wires and plugging them into a new switch?

<----terrible with electronics......

 

[Absit]

Ah, well then, thanks anyway! Looks like I'm going to give the RoadSurge box a shot after I talk more with him.

 

[Bender]

Yes you can just extend the wires to a toggle switch. It is the blue/red and black/white wires (out of the 5 total). Note that you will want to use a relay or something if you want your "overdrive off" light or something to still work. That's the Red/Green wire.

This is one interesting thread, but I still have a question.

Which would be a better mod: Shift Box or Shift Kit for Daily Driving.
Also which Shift Kit Spring would be better for Daily Driving: Black(Hard) or Red(Soft)?

 

[ramsack]

A shift kit, and the spring depends on how hard you want the transmission to shift. In my '90 FWD N/A automatic I used the harder spring, capped off the line pressure solenoid, and added a little cooler.

 

[pitt97gsx]

I thought the Shift Box allows it to shift harder when turned on and shift normal when not turned on, so that you don't have to have it shift hard all the time. Is that true?

 

[ramsack]

I have no experience with the shift boxes but all they do is alter line pressure. A shift kit changes the actual mechanical operation of the transmission along with line pressure.

 

[Bender]

Yes that is true. With full line pressure (from the shiftbox) you will hardly notice the shift kit at WOT if it is installed.

I sell both, so whatever you decide just shoot me an email at [email protected]. I'm typically cheaper than most places on sale.

 

[pitt97gsx]

I sent you an email Bender

 

[Bender]

Responded, ignore the PM I sent you. My email is working again.

In case others were wondering, I recommended him a reprogrammed Eprom TCU.

It allows stock driveability for part throttle and downshifts, but automatically kicks line pressure up at WOT to help keep the trans from slipping. Offers the best of both worlds for cars performing DD duties.

That sounds like something I would like to do, excuse me I didn't read all 4 pages all of this electric work actually kind of scared me.

So are you saying that an Eprom TCU is capable of being programmed so it had full line pressure at WOT but when normally driving around town it shifts normal?

I'd like to elaborate on this a little more as I was looking for a simple step to step on how to do the blue wire mod but this sounds easier and more reliable.

 

[Bender]

Yes.

I just saw this. I think I answered your questions on my forum already.

 

[97gst_spyder]

So is there a way to burn your own TCU Eprom chip for your car? I have the Eprom TCU already.

 

[Sinister96]

old post new thoughts. using the WOT blue wire mod that bender has on his site, im going to use a momentary push button switch mounted under the gas petal. When the petal is fully deprssed it wil push the button in grounding it. By grounding it it will activate the relay connected to the blue wire, in turn grounding out the pressure solenoid and giving full line pressure, when petal is released the relay is deactivated giving tcu control of pressure once again.

 

[goodbuds]

WHAT???? i want pictures please seems like a good idea.

 

[Sinister96]

gonna try to have it done by next week for the meet were having at the strip. i will be posting step-by-step pics, as long as everything goes well.

 

[Doubleot]

I was on my way to do this but ordered a shift box instead Full line pressure shifts are no joke

 

[Thermal GSX]

YEAHHHHHHHHHHHHHHHHHHHHHHH.


Go under the hood, and look on top of the transmission for a plug that has an orange, blue, yellow, and red set of wires in it. Cut the blue wire in half, take the harness side of the wire, and solder on a 10 watt, 10 ohm resistor, and then ground the other end of the resistor. Now you have full pressure, but like 97eclipseboy said, it sucks for everyday.

So all I have to do is go cut the blue wire and solder 10 10 watt and ground it to the frame and I can have full line pressure with a tcu

youre better off tossing the tcu in the garbage and getting a shift box. the tcu seems to cause more problems than its worth.

Are all the shift box the same or is one better than the other

there are a few options that he has based on what you might want. i have one of his older models and im extremely happy with it.
