Open source Firmware?

James this was my initial thoughts before finally giving in and purchasing one for the wife's MY12 TDV6 with the 2.7 as it was so highly recommended on the AULRO D3/4 section. Her vehicle already has a Bell Auto Service ECU remap tune along with EGR removal and disable patch. The throttle controller is brilliant on her vehicle. It's not a replacement for the tune, but it works along side. The major factor here is that the D3/4s with the 2.7 TDV6 and 6 speed ZF automatic transmission have a horrible hesitation as it panics and stuffs around with gear selection at the very worst time when you are pulling out into traffic in intersections and round about - it's horrible and leaves you with a limp car going nowhere while the traffic is about to drive into the side of you! This throttle controller has solved that. We bought another one for my Dads MY12 D4 TDV6 too. The wife runs hers on the automatic setting and Dad runs on one of the less Ultimate settings. I often forget when I jump into one of their cars and am surprised by the sudden rip off the line. But I suspect these are a particular to this vehicle and a bandaid solution for the issue they have. I would't treat this as a foundation that they're good to go for any other applications.

I believe for many drivers pushing the pedal all the way down feels naughty - you're taught this is bad for fuel economy, rough on the car, etc. Suddenly when your only pushing it 30% of the way but it's acting like 90% you get the fun factor without the guilt - this is just my suspicion on why people like them so much for other applications.

I find this strange on a D2A as my EU3 with

ahem

some mods has brilliant throttle response with a BAS old time tune.
In fact in low range it is a bit too sharp even with the dulled down mapping there.
Mine feels like a V8 on take off after a tiny bit of lag even to sometimes chirping a front on a right angle take off before the TC cuts.
I could not see how a throttle controller could improve mine.

All due respect but this statement couldn't be further from the truth.
Now, i can not speak for a td5 disco (as I've never owned or driven one) but my old 2.8 duramax Colorado with a 6 speed auto was a completely different vehicle with an iDrive plugged in.

On the highest setting it was honestly dangerous and borderline undriveable. It was just a constant battle with the traction control from the absolute second you touched the pedal. Best way to describe it was like taking off from the lights in a manual, building up about 3000rpm and just dumping the clutch every single time you tried to move the car forward.

But on the flip side, on really rough hill climbs i would turn it right down to exaggerate the factory delay. That was very helpful when bouncing up steep hills trying not to mash the pedal.

Obviously they do not increase power/torque but what they do best is give you access to all the power and torque available that's usually hidden behind factory throttle delays. In my case of the Colorado, they had something ridiculous like an almost 2 second delay. You don't realise how bad it was until you remove it

Mine has the old ECU which is chipped. It too feels like a V8, and seriously surprises. Wheel chirps are easy. It too requires finesse in low. Still lags a little bit unless full throttle is applied, when the TC light shouts.

TD5s are great.

Yes a 2014 Challenger owned by my daughter was similar.

Extreme throttle lag followed by a dramatic launch forward and BANG auto change from 1 to2.

I found it intolerable and if I owned one it would have been the first thing I changed.
I think it was somehow involved with emission tuning.

One of my brothers has a late model Mitsy sport.

He had the same result as you did after fitting one,a completely different vehicle to drive.

The face lift 2016 onwards LC200 has a "PWR" button,and it does something very similar,changes the throttle mapping,and changes the way the vehicle drives completely.
Although they seem to have little if any lag without the 'PWR' button on.

Hi Shayne, no worries... I'd be interested in getting some more info off you later, my knowledge of them is somewhat limited I'll admit... Really pushed for time at the moment but will definately follow up later.
