Hi

Where do I get the best 300 bhp setup for my 1993 Cossie (chip, actuator, injectors etc.)?
I prefer a closed loop setup.

Motorsport developments will sort you out m8,i've just upgraded to a t34 and am going closed loop too.

Cawood

just go to NMS and get there 'gunship' chip

300bhp without the need for a 3bar map, greens etc!

As above, gunship is awesome.........

I8A4RE

Yeah. i've seen that gunship setup. Is that a closed loop setup?
As far as I can understand from the NMS webpage, it seems that you doesn't have to change injectors? Sounds strange to me, that the yellow injectors can flow enough for 300 bhp and 320 lb/ft??
But great mapping with 22 psi in the lower revranges and lower boost in the higher, as I prefer to keep the car at a safe distance under the revlimiter (no need to hit the revlimiter IMO). All action between 2500 and 6000 is great for me.

Anyone know about the stage 2 setup that ABC motorsport offers?

you car is 4x4 so shouldn't be fitted with yellow injectors

iTrader: (2)

^^^ dont the 2wd yellows flow about the same if not the same as 4x4 dark Blues anyhows?

I8A4RE

Correct! What I meant was dark blue injectors.

I can reccomend the MSD closed loop setup,top performance and value and of course its easy to get technical support.

i am rinning a NMS set up similar to the gunship conversion but with greys and a 3 bar, it gives 310 bhp and 346 ft/lb, cant fault it for the money

Your car already has closed loop fitted as standard..

Take it to Karl at NMS for the gunship map, i had it on my old Saphire 4x4 and was very impressed, did not even have to change the actuator.

I was given the choice by Karl if I wanted to keep closed loop or not.

He just adjusts the map to suit.

our stg 2 is very good sees around 300bhp and 310lb ft on light greens and 2 bar can peak 20psi and hold 18 psi.and thats not a proper closed loop on a 4b4.give us a bell or pm me cheers

Do i have closed loop as standard too m8,k reg 4x4 saph cossie ?

RS-Leigh

iTrader: (2)

Check just behind the turbo on the manifold......should be a lambda sensor there

All green top saphires and escorts came with closed loop.

Leigh

cosrep

Ok what exactly is closed loop?

My car has the blue top engine how does it differ from the green top engine?

KSA-Cossie

iTrader: (4)

I have a lambda sensor so i deffo have closed loop as standard ?

RS-Leigh

iTrader: (2)

Yes

But you have a stage 3 chip which may or may not have the closed loop function on it.......i would guess that it probably does not have it on.

Question for you..........did you buy a cossie to have good fuel consumption??????? I know i certainly didn't, so why bother with it??

My 3dr is running a T34, greys and around 33psi on full boost, i drove down from coventry when i bought it and was on and off boost all the time down the motorway, i still avareged around 28mpg over the 170 mile trip. Thats good enough for me on the m-way.

iTrader: (4)

I've upgraded to a t34 and need a new chip and don't want to pay an extra £100 for closed loop if i already have it.

RS-Leigh

iTrader: (2)

Green top engine was the fitted to the facelift saphires and is the unleaded engine.

Closed loop lambda control.....basically at low boost, usually below 5psi, the ecu ius getting the air fuel ratio from the lambda probe, the ecu adjusts various things to keep this at about 14:1 ish, thus your car will be more economical when driven at a constant speed....say long distance m-way driving.

Above 5psi, the ecu ignores the probe and runs off the installed map, which has been adjusted to get differing afr's at differing rpm/boost levels etc.

Very basic before the 'experts' get on describe it all indepth.

Leigh

KSA-Cossie

iTrader: (4)

Aahhh right,might have to open up the ecu and have a gander.

RS-Leigh

iTrader: (2)

You have the facility to run it, ie the ecu and the lambda probe but your chip will have to be written to include closed loop.

Ok leigh thanks for you replies pal,it's a learning curve !!

I'm either buying direct from stu at msd or the one in the cossie parts forum.

My answer to your question, for what its worth...

No, i did not buy a Cosworth to get great fuel economy... however:
EVERY car produced in teh 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 teh ecu. Instead of teh 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 that i recall. lol

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 teh good old YB burns it easier. My last Nurburgring run showed 30laps of teh cuircuit, 2000 hard miles and less then 1pint of oil consumed when i got home.

My software for closed loop is far better at idle valve and cold control than most tuners non closed loop software as i have dedicated the most time to perfecting it, remember, it was me that did teh first ever closed loop on the Weber L8 in this country that had teh correct map pressure 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. Is that perhaps worth the extra then even if teh fuel economy isnt?

Money: All this extra cash i have from spending less on fuel, less on tuning and less on oil i can spend in the syndicate Tomorrow nigth with Dan.

Of course, all you who truly dont care about money can simply say "I didnt buy a car for fuel economy" Cant you?

P.s.
from 1992 all YB's had closed loop enabled for their standard injectors and 2bar. This involves no extra ECU hardware at all over the standard 4x4s, just new software, so of course when you take Fords software out and install another tuners without closed loop, you have lost the capabiolity. Hope that clarifies.

cool explanation stu!


my k plate just needed a chip from stu and off i went! 35+mpg on a run, as said great when cold, great at idle,

it changes your cossie from a drunken beer drinker round town, to a tea drinker (with a little pinkie out!)

what sort of power increase would i get from changing from standard to BD10- cams stu?

Stage 3?

Stu @ M Developments

iTrader: (12)

Generally speaking, you would lose midrange torque and gain some top end power, but economy and low end driveability will normally suffer too.

JTECH James

iTrader: (13)

wont be doing that then!

another thing to cross of my shopping list

i just feel i want more than stage 3 now...... i'll have to go greys!

Stu @ M Developments

iTrader: (12)

At least... or maybe a nice set of siemens 55lb and a shiny new closed loop chip sir?.

JTECH James

iTrader: (13)

mmmmmmm, im listening.........

so i could run that on standard cams ,closed loop, T34.48? 7.2:1 cr.



what power? when, how!!!

m_nettleship

stu, I am not to up to date with. what had witch at what year, mines an 1988 sapphire, and I think it came with red top, but not sure about that either. and I dont think it runs and lambas at all.so just wonderin what colour top it would have cum with.. is there many people that go closed loop, on a year like mine.

Mines in the process of bein rebuilt but the engineerin company, have made a mess of a sum things. Cheers for help pal well appreciated.

JTECH James

iTrader: (13)

Green tops, 1992 ran closed loop as standard.

to run it on yours you should have a L8 ecu ,make sure it runs a standard board ,not pectel, then buy a chip, lambda sensor and boss from stu, wire it up and hey presto!

Stu @ M Developments

iTrader: (12)

You would normally see around 380bhp max due to your limiting turbo and head. A bigger turbo will help you do it with less strain. Your compression is a tad low for sub 500 really IMO.

Stu @ M Developments

iTrader: (12)

Correct.
