A long time in development and now perfected for mass consumption!

Package consists of the following;
Adaptronic 420d ECU - http://www.efi-parts...p?productID=248
Full install utilizing the oe loom to retain full backward compatibility
Custom fully adjustable pedal (position / travel and tension adjustment)
Custom full 64mm throttle body with custom spring setup (ported / gas flowed / fully refurbished) - VXT inlet manifold is 65mm
Performance high quality throttle cable
Full fitment of pedal / cable / throttle body & configuration (set to oem travel & feel)
Custom mapping as per customer requirements / hardware
Option to set / reduce boost per gear boost (key on higher power Vx's to protect the known weak point - gearbox) *requires extra loom and hardware to configure

Option to upgrade to the Adaptronic 440d ECU which amongst other options supports traction control - http://www.efi-parts...p?productID=246

The current solution using the oem ABS signals has been tested but not configured on a VX220 yet. This will required some R&D to complete but has infinite settings and adjustment for how you want it to react (planned on 2 vx220's but as I type not configured) PM for more information if required

Cost
£2250 drive in / out full conversion (420d)

I don’t have to tell everyone the limitations of the oem management and the poor part throttle response or the way the oem system can hold the hardware back. This whole package started to address this and delivery a very linear delivery from the z20let/leh setup, I always hated adjusting my driving style to drive around the shortfall of the oem setup in particular part throttle on track / great roads.

Simon (MrSimba) recently had this conversion and sure he would give you honest feedback of the product and improvements it brings


VX220 SC under review for a different (bigger TB)

Stop it, I REALLY don't need to spend anymore money on my VX. Seriously, stop it now. About that traction control...........

Would be interested in the SC solution.

Lots of info / progress of Simons build / standalone conversion and feedback on below link;

‘Cable throttle ace!

Held off getting back to you on this Chris as Dave & I wanted to make a couple of adjustments to it before we were perfectly happy but can confirm now it's the finished item

It's slightly heavier than oe, but only very slightly, & for the better for it as its much more controllable!

The real difference that going to cable makes is that your foot is in direct control of the throttle body, 25% at the pedal is always 25% at the TB, no ECU in the middle trying to guess what you want or interfering!
It makes the power delivery very very smooth and you feel much more connected to the engine, so all good

Also with the cable throttle pedal that Dave's designed you can adjust EVERYTHING, pedal height, pedal depth, pedal travel, feel on the cable from soft to hard, how you like the feel of the pedal when returning under your foot, EVERYTHING! can't do that with oe!


The car is actually very different to drive to how I imagined, Far more smoother in the delivery, no on/off hesitations or stutters that the OE ECU likes to throw at you! very linear, actually a much safer more predictable car then my stage 4 was, the stage 4 had LOTS of torque2500-3500rpm (which could be fun in the wet...) then it started to fall away, the Garrett starts to make torque at 3000rpm and it not until 3800rpm that it matches the stage 4 (which is by now losing torque) then from 4000rpm to 6300rpm it holds up to 384ft lb and no less than 300ft lb so massive torque where you need it

The bhp again is under the stage 4 until 3800rpm then BOOM! its just 'Defcon1' all the way to the 7300rpm limiter

In short its more linear, more refined, much much more powerful car, but with the a far safer delivery, I had had possible plans for multiple maps, Defcon1, wet, low torque ect but after feeling just how refined the map Chris has developed multimaps are not required, this map really is just fine

Have to say though any gear, once your at 3000rpm if you do ask it to boost the car just squats and goes...! its warp speed, both I and Dave Hardwick have driven it this afternoon and both of us can't really see why you'd ever need any more power in a road car, basically its just on the limits in the dry of having more power than traction, any more and you'd be scared to go WOT, Chris actually when I got there this morning had road tested it after he finished mapping late last night and he'd backed the power off as he was worried it would start eating gearboxs! hence the 363/384!

Think the power to weight ration is now 437bhp / ton which is 100bhp/ton MORE than a V10 Gallardo! so as said ain't exactly slow!!!

Anyway the graphs.....’

The 'dip' at 5300rpm is seen on all tuners maps, chris scratched his head and could not map it out so looked at CS, Klassen, ect and they all have it so think is a characteristic of the cam profile?



This graph is my stage 4 on Chris's rollers overlaid with the Garrett map for comparison

Me too, its my next modification.

Well should make it easy for you Jimmy as I have a nice example going through the change management that is lol. Of course will be doing before and after to demonstrate the improvements

Stop tempting me!

Can I have a SC Vag Garret standalone conversion please?

[Mike (Cliffie)]

Is this what is fitted to Luke's car? What does he think of it?

[G-Bob]

Is this what is fitted to Luke's car? What does he think of it?

He'll find out in 2weeks.

[allsteel]

What's the engine spec of the car in the graphs.

He'll find out in a Duncan

EFA

Any chance of an ITB option?

Sorry, I thought it was done.

[Zoobeef]

I thought Luke was using the vag etc?

[Mike (Cliffie)]

I thought Luke was using the vag etc?

It would seem Luke is still using the bus.

[Zoobeef]

That was supposed to be ECU. His cars not back yet but he's putting it up for the winter when he does get it back anyway I think

[GeorgeBC]

Whats the damage for a forged example like simons?
