Just wondered if it is possible to have this on my standard car.

Cheers

not without swapping the ecu out for an L8

 

What needs to be done. I am still learning about Cosworths. What are the advantages of doing this?

I have read on a website it is not reccomended on turbo charged engines is this correct?

Cheers

All new cars since about 1992 have had closed loop lambda.....

The lambda control only operates under certain conditions, floor it and it'll revert to the mapped settings.

See Stu's post about half way down that page.

 

What piece of equipment do I need to monitor my engine i.e. running lean etc?

Cheers

For that, if I understand you correctly, you'd need a decent wide band lambda probe and controller & gauge - basically what tuners use when mapping/setting up a car. Bear in mind these aren't cheap, and don't have a huge life expentency when compared to the narrow band lambda probe used in todays cars.

The little dash displays that work off the narrow band lambdas aren't worth a toss - you're engine would be dead before that helped (in my opinion)

Stu sells IAW monitor software (for diagnostics) that runs on a PC

Or you can fit a SECS monitor that shows various sensor readings and error codes:

Owning a Cossie can lead to a certain amount of paranoia, but that needn't be the case if it's kept in good order, and looked after by a pro.

 

Hi

We sell the Innovate products which use the wideband sensors very neat guage. We are udpdating our website because its a new product for us so no web link available but I can PM you a price tomorrow if your interested.

If you wouldn't mind PM'ing me a price that would be superb. I'm just looking into different options at the minute as I'd rather know what my engine is doing to avoid problems in the future.

Cheers

Sadly it cant be used on a Level 6 yet.

Thanks for teh links Bill, here is the info off that topic...



This is a reply i did elsewhere copied and pasted, but 90% relevant to your question.

EVERY car produced in the world since 1992 has had closed loop fuelling control as standard. The benefits of this system, apart from giving great fuel economy (Mine on 900cc Siemens returned 34.4mpg at 80mph) are as follows:

Feedback control for the ecu. Instead of the engine wearing and then you getting the normal cosworth bad idle, my software now compensates for it. No more crappy idle every 3 weeks, in fact, i havent tweaked my idle co or speed for over a year and 15000 miles that i recall. lol

MOT: You will pass an MOT and UK roadside emissions checks, something that incredibly, a lot of cosworth owners still cannot do. lol

Great Cylinder cleanliness. Open up a closed loop controlled engine and you will note it is rather clean. None of this crappy black carbon you see baked all over engines that have old fashioned non closed loop fuelling.

Greater oil and engine life. Overfuelling engines by their very nature dilute the oil and of course this compromises its lubrication ability and then of course your oil thins and the good old YB burns it easier. My last Nurburgring run showed 30laps of the cuircuit, 2000 hard miles and less then 1pint of oil consumed when i got home. Clin d'oeil

My software for closed loop is far better at idle valve and cold control than many tuners non closed loop software as i have dedicated the most time to perfecting it, remember, it was me that did the first ever closed loop for large injectors that worked properly on the Weber L8 with a 3bar in this country with all the correct switch over points and thus doesnt allow a T4 to run 12psi at 15:1 because someone just copied fords control maps for a 2bar with no tweaks for larger injectors. lol.

We know more about this system than most and as a result our software will not give any crappy hunting when cold or poor driveability. In fact, you will be hard pushed to tell if your engines hot or cold with our closed loop software unless you look at your temp gauge. To some owners this alone is worth the extra cost even if the fuel economy isnt.

Money: All this extra cash i have from spending less on fuel, less on tuning and less on oil can be better spent elseqwhere.

Costs vary. But in a nutshell:
Closed loop chip up to greens = £250.00 (Extra £100 for greys or bigger)
Lambda if you dont have one is £80
Exhaust SS Boss if you dont have one is £20

95% of 4wd cars have the wiring as standard from 90> If you dont, i will instruct you how to wire it. Its very simple, live, earth and a signal to pin 2 of ecu. This system works with both L8 and P8 although our P8 software is £100 less as its always been closed loop from day one.

Hope this has helped.

Wasted spark:
Often known as acoilpack conversion.
This system adds a driver to your level 1,6,8 or p8 ecu that will drive a modern twin coilpack, thus running your HT ignition system in a wasted spark configuration, thus removing teh old coil, king lead, cap and rotor arm altogether. This will allow you bigger spark plug gaps and far far less maintainance. The system is also far less susceptible to moisture.

You have to have an L8 ECU mate, give Stu a call, it's easier than asking on here! He doesn't bite!

 

Thanks Stu that info is superb. I will be on the phone in the near future. Only thing is once I start making things better I won't want to stop. Think my bank balance is going to suffer a little.

 

It is certianly worth doing.

It's worth noting that the reason all cars have closed loop since 92 is due to the requitrement of a catalyst. Mixitures other than lambda 1 dramatically reduce the life of the cat. The narrowband sensor is also desgned in such a way that it can only really control mixtures down at lambda 1. A wideband sensor is far more accurate at othe mixture levels.

If you are going closed loop, and you wish to accurately monitor the fuelling, then an innovate wideband sensor and controller can be used - you don't need another narrow band sensor, as the innovate controller can ouput a narrow band signal to the ECU.

 

Your very welcome.
