Wouldn't it be nice

[vr401]

Imagine HSG RVR auto with power/economy switch. Imagine power setting with high revs gear changes and aggressive downshifting for race spec alike setup and on the other side economy with nice smooth changes for cruise like feel....

There is always hope out there, we just have to imagine........

I NEEEED THISSS!!!!!

Time to get that 5 speed

^^^ I have a GTA now also. New box to mod ;-)
You teaser ;-) Yeah Miodrag & I got together & my RVR HSG auto runs switchable tcu dual tables.
I wrote 2 new tables for power & ecconomy & Miodrag the PC guru wrote them on a 16bit chip.
My new minimum upshifts in crawling traffic at 5% throttle are 22/35/48 in auto mode.
So it holds gears until my new set minimum speeds. Wot is ecc 6k & pow 7k.
Kickdowns I wrote are at 65-70% throttle to suit my dicky right foot.
While slowing down for lights etc, I made the tables downshift for me >3 >2 >1
The bin file to read the chip I was given from a fella & it is to be kept private.
But Miodrag can write chips for tcus here. Ecc/power or even ecc/race can be switched on the fly.
This is my console with mirrors, auto/man, pow/ecc & cruise control

Cheers

Wow guys, this is AWESOME! Would be very cool to have!! So it is completely separate to the ECU and only interacts with the TCU? So if would work with an aftermarket ECU also?

Awesome job guys

ECU & TCU don't talk in RVRs.
Cheers

Nice.
This is to suit eprom tcu only?
And the power shifts are at full line pressure?
And economy shifts are at reduced line pressure?

Nice work guys

Do you have any pics of the install? Where abouts is the TCU located?
How hard was the process?

Cheers, Mike

 

[TBOWGN]

Wow, very impressed

TCU is located behind ashtray. Just take of 2 screws holding plastic trim from passenger side and you'll see it.
To mod it is same as ECU mod with addition of few wires

 

[vr401]

Dual map switching is possible on stock eprom ECUs too (manual & auto)

Yes

You could have any line pressure set to reflect RPM vs TPS setings.

Wow, impressive work guys! :thumbsup:
How do you switch between maps on an EPROM?
Using a 32kB chip, writing two BIN files and somehow switching between them or something like sandwiching two EPROMs?
You guys are taking it to the next level! I can see people converting to auto's soon

As you know stock ecu/tcu eprom/bin is 16kb and i use 32kb eprom writing two bins on it and then using switch making computer to read fist or second half of the eprom and there for reading/using two different bins.

The mad scientist! Love it.

 

[Hyper_Mike]

So awesome, If only i lived closer to Sydney haha

 

[MDK87]

Soooo cruise to Sydney for TCU upgrades Mike? haha

Time to start tuning GTA mate.

I think we should! And don't worry Mio, we will bring the beers! ;D

 

[4piknup]

so, do I need eprom tcu?
Mine is not eprom. ...
Do I need to get a 1g eprom tcu?
