do you get better mpg(if so what sort of figure) and is it worth the cost(how much is it?)

any info/help would be apprecated

 

xrt_si just got it, i think he was saying it put him @ about 35miles to a gallen cruising, a tiny difference on around town driving but not much, thats running on black injectors with t34 etc

 

Amazing difference,35-38 mpg easy,bought my new closed loop chip at xmas time when there were good deals on.

 

they pay for themselves in a couple months or so. i used to et 200-230miles but now i get close to 300,

 

Seems good, as R5FORD said bringing a tanks worth of petrol upto about 300 mls from low 200's.

 

As above used to get 230 on light greens now get well over 300 around town with dark greens on closed loop

i wont be running msd closed loop fwith my new engine as iv gone for a new ecu but still should have the same sort of mileage.. well maybe abit less as il have a lil more power.

 

nice one guys

any idea on cost ?

last tank cost me £71 and got about 240miles

 

IIrc with t34.63 and simens blacks its about 350 quid.

 

Kev is that with the chip

 

yes thats with the chip, as above i get about 300miles to a tank on a t4 and siemens 83Lb, a friend running greens doing the same trips as me same speeds no closed loop gets considerably less miles

 

Thats the chip and full fitting instructions matt.

 

Add the cost of all the msd bits up, CL coilpack etc then chip/mapping and it's very expensive, most aftermarket ecu's do this as std, for less.
tabetha

 

yeah i know but aftermarket ecu's are abit involved for me i want plug and play

 

Go on then, lets see.

WS Driver. £140
Closed loop greens chip. £240.

So a L8 for the YB is up and running with WS capability, serial datastream output and Closed loop capable for £380.

Now show me an aftermarket management system that comes to less than that. better still, show me one thats less than that FITTED AND MAPPED as well, since thats what you just stated.

 

Plug and play as in what? If you mean ampping etc, then Tabs is correct

 

I suspect he want's to recieve a chip in the post put it in his ecu and drive it i.e plug and play, not have the hassle of fitting a full after market setup, find someone to map it organise it, lose the car for a week having it mapped etc.

 

exatcly

 

Stu

already got the ws driver in my L6

so all i will need is new chip, closed loop board and lambda sensor

best get saving then

 

im on closed loop wih 55lb siemen injectors running 370/380 bhp,and driving pretty conservately am only getting 220 -235 to a tank.will coil pack enhance the mpg return and the driveability of the car to warrant the cost of converting,all replies would greatley be apprreciated

 

Ive had it done last week or so. I am on 55lb blacks, T35 and running about 390bhp.
Idle and drivability has improved (mostly due to MSD chip). Driving round town and putting your foot down still uses a lot of fuel but off boost driving it really has massively improved.
On the motorway at 70-80mph it happily hits 35mpg. Big big improvment, and defo recommend it but dont expect miracles if its mainly round town driving you do.

 

fuel economy is only one of the benifits though...


better engine oil life, better engine life ,to name a few other benifits from it

 

are you sure that its going into closed loop properly? I would reccomend that you talk to MSD and get there take on it, you probably need to check the co etc to make sure that the closed loop is working. Im lucky in that I know when mines working as my wide band afr shows pretty much bang on 14.7:1

 

I assume that is cruising off boost, if so, I get that without closed loop...

 

Sorry mate, I misread your comment

 

Why do you need a coilpack? You DON'T to run CL!

It's WELL worth the money IMO, doing a 900 mile round trip that included 140+mph runs frequently Plenty of stopping and starting, normal driving and sat in traffic, so every variation I got an AVERAGE of 32mpg and over 340 miles to a tank!

Driving carefully and on a run I can see WELL over the 360 miles per tank mark!

 

Bttt for Tabetha.

 

No answer StuI wonder why
Then theres the cost of mapping yourself,Laptop,time,monitoring equipment and lets not forget

KNOWLEDGE
OR ITS

MELTED PISTONS!!!

Paul

 

Being able to take it to any MOT test centre knowing it should sail through the emissions is another bonus i'd say!!!

 

Wont an L8 be needed too ?

 

yeah just got one off ebay

what i ment was that could take the wasted spark driver out of my l6

 

so matt 168 for the ecu then 600 for a live map sorted unless u change the inlet

 

Nice one matt.

 

BTTT again for Tabs...

 

For anyone and STU in particular I said with all the other bits meaning other mods, granted IF you already have a CL capable ecu it's not too bad a price, unless you want ALL the capabilites of a ecu ie coilpack as well, it just does not make economical sense.
Depedning on your driving style it will take a long time to recoup costs, and msd mapping is extortion IMO.
Why do people bang on about economy when they buy a cossie, buy a diesel, can be much faster and economical.
Msd are not a infalible entity they make mistakes as everyone else.
For me I just can't see the point of paying loads of money to upgrade a ecu that still lacks loads of features, and does not do much at all compared with aftermarket.
this is assuming you don't have to buy a new ecu in the first place if the std one isn't a capable one.
add on the cost of LC TC CL CP EGT onto a weber ecu oh sorry you can't it doesn't do all the above does it, and of the few above it does do price it all up, look on ebay as prices are better, then you could end up with a low feature single map ecu that works with increasingly hard to get parts, whereas(some) other ecu's are only a computer switch away from changing/calibrating of some sensors, so that sensors from loads of other cars can work, so not shortage there.
A water temp sensor can be calibrated with a kettle and ice if you can't get an original, you DON'T need anything special software wise, and new features are added FREE all the time, just a download away.
Watch the news stu ecu's can now be bought for £350, as advertised in either fast ford or performance ford(can't remember which), granted a basic one, well sort of still does all the modded std ones do though.
tabetha

 

there are some SHOCKING fuel economies going on here!!i could regularly get over 300 miles to a tank in my old greys t34 cossie engine without closed loop,it did go down to under 200 when giving it some though!lol!
maybe im just more thrifty than others when driving slowly?
definitely sounds like a worthwhile conversion though

 

I've got a stage one closed loop,its just under half a tank with 189 miles on the tripometer.Considering i do a lot of short journeys i think thats pretty good

 

But this topic is ONLY about closed loop mate. Not coilpacks, televisions, sweetcorn or sex with ladies of the night.

Still, lets humour you shall we and add WS on. So we are now at £780, job done. Your cosworth is now closed loop, with wasted spark. Fully up to date. total cost = £780inc parts and vat. So again, lets see this done cheaper using your aftermarket all singing all dancing ECU. I look forward to your costings...


What have costs got to do with it? Closed loop isnt just about fuel economy, its also largely about hugely decreased engine wear as well. That said, going form 18 to 33mpg will save you a LOT of money if you do 12000 miles per annum. Anyone want to work it out?


Really. Which mapping? What ECU type? Why is it extortionate. What are you basing that statement on?


As above. Although that said, lets get this right;
You are saying that if presented with two identical cossies for sale, but one is advertised that it does 33mpg and teh other one does only 15, both give the same performance but the one only doing 15mpg is wearing out far faster and using more oil too, (not to mention the black smoke and stains all over the nice white bumper) that you would purchase either of them because you dont care about the extra fuel being wasted in the sump and out of the exhaust, teh extra oil costs and the extra engine wear costs yes?
It wouldnt bother you in teh slightest and you would be happy to drive either? Sorry, but i suggest you are talking rubbish, or stupid.


Agreed. Who suggested otherwise on this topic though?
This is seeming like some sort of anti MSD crusade by you, especially after i quickly look at your profile and find this from you about me too which is TOTALLY off topic on some poor sods thread.


But what it does do, it does better mate. Far better in most cases. have you actually tried some of these cheap ECU's mate? A lot of them are a joke when it comes to refinement, and some of teh cheaper onees dont even have idle control.


Sorry? Watch the news? £350? What are you talking about man?
If tha odd statement is somewhow in relation to my question to you, which was "Show me it done cheaper" well i was at £380 DONE. Drive away. Finished.
You are still at £350 for some shonky ecu (Whos name you cant remember) in a magazine which you havent bought, paid for shipping, mapping, looms, sensor changes, sensors. Blimey... surely you can find a better reply than that one as it simply makes you look as though your clutching at straws.

 

How the fuck is 500 quid for a live map that takes a week extortionate ??

 

of the day goes to tabs!!!!
