laguna coupe
do this knaker your engine up and what do u need to do to get it to spit flames like that
ok Jon, will put them back when i see you...
you need
Aftermarket ECU
Cable throttle body
Mechanical Throttle pedal
Cable
Mapping
I would like to add some facts about the drive by wire (dbw) systems in addition to what Andy at GDI has correctly said. There is a bit of a misconception generally about why DBW exists. In a production car there are two reasons, the first being emissions. It is much easier to control exhaust emissions when you have the throttle plate under ECU control as you can not only control fuel quantity and timing but also the admission of air into the engine. When the throttle is snapped open on a cable throttle the ECU needs to add a 'slug' of fuel to compensate for the sudden increase in air. This is known as acceleration fuelling. Becuase for Euro IV standards the amount of acceleration fuel is very limited, it is necesary to slow the opening of the throttle plate. This causes the poor throttle response that we all hate. Because MOT tests only measure steady state emissions we don't have that problem. The second reason is cost. It is considerably cheaper to do away with the cable, idle motor et al when a new car is being built.
Now you may ask why some top racing series then use DBW throttles? Well, they are optimised for performance with very fast throttle opening times. But acceleration fueling is then required! Again to have total control over airflow is useful especially with turbo anti-lag systems. But in the real world the advantages are almost non existant.
At Omex we have the facility to operate DBW systems but the software is currently disabled due to safety and product liability reasons. The amount of testing required is phenominal and commercially makes no sense as the demand is very low. Also we are fully insured for product liability, a process that is far more complicated than you may realise. We have to provide failure mode analysis information that allows the insurers to decide if they will cover us and to evalulate the premium. Believe me, the cost of insuring your 172/182 is not a drop in the ocean compared to our premium. At the moment we cannot provide our insurers with enough information to allow them to calculate the risk and hence a premium.
I find the comment that we are 'covering our arse' rather insulting. By being properly insured we are showing a responsible attitude to our liabilities. For example, if we were not properly insured and any of our customers had to make a serious claim against us (say £1M plus for a death) we would be bankrupted and no money would be paid out, leaving the car driver to pay the bill which would in turn bankrupt them. So our insurance covers the customer for their liabilities. In addition to obtain full liability cover we have to undergo rigorous testing to allow us to 'e' mark our units, a legal requirement that many of our competitors do not undertake. Without this the ECU is not legal to use on the road. Interestingly we have just had the first instance of this being required, with a customer having a nasty accident and the investigating officer has contacted us for copies of our certification.
So I hope that helps.
Interesting find Mark, but the Omex does support it, just the feature is turned off just in case some have a go hero decides to piss with it, or power washes the engine bay and the ECU then cuts out at 4k rpm on the motorway due to it Looking at the list the Omex does a lot if not all of those listed. For the price they are arguably the best, hence the popularity.
You can have flames, pops and bangs and still have it drive and run perfectly smoothly, I think your own level of mapping expertise is making you somewhat naive and ignorant in your old age... anyway, wouldn't be too anti Omex... or have they sent you a new ECU so you can safely nit pick away from the safety of your keyboard?
Motec for example, they can do FBW no bother, but at around £4K installed you'd expect it to wipe your arse too

Exactly!
It seems my post has been misconstrued. You pay your money and take your choice.
I dont think the guys at OMEX would argue there £600 ECU is competing against EFI's and Motec's.

Just made some fairly valid statements as fair as I can tell. I dont think I was slagging OMEX off just pointing out there are better ECUs out there if you are prepared to pay the price.
There is to much back slapping and bulls**t going on in these threads. If someone wants to challenge/correct what I have posted then carry on.
You obviously dont know anything about it so why have you posted?
Exactly!

How can one unit be so superior to another? I understand sweet fa about ECU's.
Is it not all down to the mapper at the end of the day? Is that why you are paying the £4k premium? over £600?
Exactly!

It does more faster.
EFI Euro4 spec
40 MHz PPC microprocessor
*4 cylinders in full sequential mode
*6 and 8 cylinders in sequential injection and wasted spark mode
*On-board data logging
*Automatic fuel control
*Closed loop lambda control (OMEX can but you cant attach wideband direct)
*Automatic boost control
Variable camshaft timing
Idle speed control
*Drive-by-Wire control
*2 selectable engine maps
OMEX cant do all the things with a star by it.
fancy s**t is the answer LOL

But what do they all do? Means nothing to me:S
Wasn't the DBW issue discussed a couple of page's back and the conclusion was that it could run DBW, however this was disabled for insurance reasons.
NOTE: Sativas are better then indicas. Give you a better high, the indicas are too mongy.

sweet, just dont tell the missus. shhhh lol
