As i was working for the vag group at the time, and had access to resources such as bodies/pedals and as importantly wiring diagrams, i used.............vag (bosch) dbw equipment.

GEMS write my control software.

Very reliable system.
My pedal was off a 2003 SEAT leon 20vt. As was the throttle body,but there are hundreds of options that will work.

Out of interest it took my mate £14k for one day at brunters with the Mac factory and he only just got over 200 in a Mac f1

Rod-Tarry

Yes ive looked at these they are one of several in the States but im on the trail of something similar from the UK.

Rod-Tarry

With the new engine we should be in the 213/215 range. You cant compare a Supercar with an aging Ford but in that discipline the old banger would show the Macca a clean pair of heels although no owner would believe that .

Rod-Tarry

I have that pedal on my list is it a 6 wire system system.

markk

iTrader: (2)

It is a six wire but we only use one pair of contacts for the main stream (we keep the other for emergencies)

Rod-Tarry

Thanks for that info it will allow Mark to configure it the way he wants.
I may buy a cheap second hand unit on ebay to see the possibilities of it fitting.

markk

No worries, i have lots of info on the bosch systems if you need anything.

Rod-Tarry

Thanks will need wiring diagram im sure they are hard to find.

Is driveability of a road car still something your after? It seems it could be better at both ends of the rev range than before.

Rod-Tarry

Yes its a road car will only do one more Topspeed run. The 9180 will spool about 1000rpm earlier than the GT42 ( we have seen that recently on tests) & make maybe 60 more horses so it will be a major step forward as a road car. For the last Topspeed run all that goes out the window its purely about Power nothing else. How fast the car goes will depend on how much Power Mark will let me risk. We should have circa 1000bhp on the GT42 & a similar amount with the 9180 with a shot of gas. IMO we will not risk more than 900bhp for 1.7 miles so its up to Mark what combo is used.
Our last completed Topspeed run was back in November 2005 & its strange that this car is still seen as a Topspeed car it never was. Its one of four road car in the family & at that time in 2005 I still drove it to work.

Rod-Tarry

The first of my trial pedals arrived today. Jenvey are e-mailing the detailed wiring info on the ETA2 system they have not yet made it public on the web.
Ive yet to confirm how it works but it appears to be a Master/Slave concept with a TPS in the unit & another on the ITB's they will monitor each other & send info to the ECU which drives the motor. The Pedal will say how much to open & being 6 wire will monitor itself for errors. Any errors will result in limp home mode.
Ive just guessed at this & await the info to check.

Will Pedley Racing

I know the belt and braces approach is to use a 6 wire setup so that you have 2 self sufficient pots on the pedal, but for what it's worth, i've run the 4 wire setup pedals (common reference voltage and signal ground) successfully for a good few years now without problem.

With correctly configured redundancy strategies there is no reason that they should be dismissed

Might open up a few more options for you

Rod-Tarry

Yes Will im aware & Mark has already said he can use the ECU to detect problems so its really just belt & braces. I have a pedal that is 4 wire that looks like it may be suitable & if the couple of 6 wire im trying cant be fitted easily I will go with the 4 wire .

Rod-Tarry

Waiting for info from Jenvey .
This is the CDI/Coils loom that will plug into the Emtron loom. Its at least a start on the wiring.

ajamesc

Dafs use electric pedals rod have done for years there's is a simple system has 2 circuits in it and 5 wires. An idle validation switch which is iver on or off to let the ecu no the pedal is at idle. And a 5v supply and earth with a signal wire for the throttle side the 5v varies on the signal wire back to the ecu to tell it throttle position. They use iver a potentiometer or a hall switch depending on age. The fail safe is if the throttle side on it go's it still has the idle switch that will give it a limp home and 10% in it's pedal range and if the idle switch go's it will idle at 3000rpm iver way you can still get home

Rod-Tarry

Have paid for the Emtron ECU today so that will arrive in a couple of weeks.
No progress on the Jenvey Electronic Throttle spoke to Simon today they are having a bit of bother with the manufacture of the gears so delayed date for production. Couple of other parts also not happening as quick as was forecast. Same old problem Ive the money to pay but you cant buy quick solutions at any price .

Ahead of the game so to speak .
Rod are you still using the system I recall you mentioning ages ago where you run a safety backup if you have a voltage problem or can the new ecu and fly by wire do this instead?

Rod-Tarry

I run an Accuvolt system & it will supply an adjustable 15v at all times until battery volts drop below 9v. It means if an alternator goes down it will still get 15V+ & not drop an engine on a Topspeed run.

SiZT

The Renault system I mentioned is a Renault Scenic/Megane one

Rod-Tarry

Thats 1 of 3 that im looking at have purchased a used one from ebay. That may work with my existing pedal .

Rod-Tarry

Not much to report.
Heard from Vibration Free today my 1off crank Harmonic balancer is ready & only needs balancing will the rest of my stuff.
The Pistons are now well over due so need Mark to get that sorted.
Will visit Mark on Wednesday to see whats required to fit the Leon DBW Pedal.
It came with its Loom & the internet supplied its secrets & it will plug into the Emtron Loom.
Will not be using DBW on the Dyno as its easier without. The loom will cope with both interfaces .
The Emtron is due shortly & then i can at least start on the loom.

My pedal is 1M leon, i use 1 of the pots, but the other is ready to use if needed. Just an ecu inversion.

Rod-Tarry

Agree will wire both pots but only use one.

Rod-Tarry

Jenvey contacted me this morning with full details of their ETA-2 including wiring details. Its as simple as i thought so no probs. Can use the p&g TPS ive already bought & the other will be supplied.
Need to get to Marks this afternoon but the Missus has other plans. I will however sneak off at some point.

It fits like this.

Some very old videos, definitely back to 2009 when I first developed my YB active throttle.


and the software running it showing logic checking and error corrections

Rod-Tarry

As always when i go to Marks I have more problems when i get back than before i went .
I removed the old pedal & tried the 3 options. One was a total no-go the Leon pedal could be made to fitif desperate & the Peugeot 307 pedal was simply made for the job, correct angle & length so an easy fit. As we are using only 1 pot this pedal is perfect so one problem over.
Mark then mentioned the other things he wants wired into the loom.
All 4 wheels to have wheel sensors not just 2. An input for Fuel Temp to help with mapping. Mark wants 2 map sensors one to deal with Boost below 3bar (45psi) & the other dealing with up to 4 bar (60psi). A normal 5 bar map sensor is not as stable at lower boost levels hence the ECU will be configured to switch between the 2.
I will post up the Wiring Diagram when ive made these changes its getting rather complex compared to all the other Cossie looms ive made .

Caddyshack

I see you are using Peugeot parts, do not get tempted and nick bits off the old red Peugeot he has in there!

Rod-Tarry

Yeh !
Rather tasty that .

Counted 6 EVO's, 3 Cossies & a Pug in there today. Still got that hairdresser Porsche outside . Even my SLK looks masculine along side that .

Caddyshack

Thanks, it was rather full when I went there....lots to drool over. Hope mine will leave soon....maybe see yours or bits of it when I pick up?

Rod-Tarry

Mark rang to say he was holding some porn in his hands so I guess the ECU & looms have arrived .
Will take a trip to Marks tomorrow to pick up the loom & also try the electronic pedal ive modified. Still no news on my pistons which are several weeks overdue which is annoying. The parts from Vibration free should be ready to be picked up next week.
Have received details from Jenvey on the throttle motor so i guess thats now available.
At least i can start on the loom next week & build it with no deadlines looming which is a bonus. It will certainly be the last loom i ever build so the end of an era .

Its not the end or even the begining of the end of this build but maybe just maybe we are at the end of the begining.

Rod-Tarry

The loom arrived. Not sure if a pensioners brain can sort that lot .




Also sort of abandoned the dbw fitment we both agreed we have enough to cope with getting a 1000bhp YB sorted & this extra function can wait until its all running & sorted. The loom will allow a future upgrade if its required.

ajamesc

That's a lot of wires lol! See yours the other day rod looks sorry for its self at the moment the thing is gagging to be driven out of there under it's own steam and cleaned!!!

markk

iTrader: (2)

I would hardly say thats a lot of wires really.

Get the dbw on whilst its being built, theres nothing to it.
Looks like ill still be the only person with a dbw yb still 😀

Rod-Tarry

Only 116 wires so your right not a lot.
Its not the number of wires but the number of joins that are required. Only one 12v Supply wire that needs to go to 15 places is a joke & they do supply 5 sensor grounds but i need 20 .

Yes it looks like you will still be the only yb on DBW we were changing the Spec on a weekly basis & the goal post was getting further away so we decided we will build to the present Spec & not change until its running.
That also includes not fitting the Nitrous. We do not intend risking more than circa 940bhp down Brunters as that should see a chance of 215mph & we should have that off the gas.

markk

iTrader: (2)

That's a small number of wires for an ECU, in the industry over 250 was not uncommon that I was working with.
The joins are not uncommon either, I just hope the feed and GND are both big enough if there are only one of each. Though, the load calcs work out easily if you connect the right amount of highsides and lowsides correctly for outputs.

The sensor 5v is not really an issue distributing it, though as you are fully aware, takes a lot of planning when loom building!
Good luck

Rod-Tarry

I did design but not build looms on the Tornado Project many 1000's of wires in that but a very large budget . Funnily enough only the dbw motor would cause a problem in this application & thats feeds through a relay so no such probs. My loom experience is a long one remember crawling around in Concorde 2 back in the 60's rather more wires in that .
Only started on cars when I retired I designed & built Marks looms to a price for 6 years before he made me redundant through old age last November .
