Hi all at passionford...

I have emailed Collins Performance, but haven't gotten any answer back. But perhaps some of you can help me


I've got some question I hope you have the time to help me with.

Recently I bought a Cosworth 2wd Saph. The pervious owner used to buy equipment from you. The car is supposed to have en Collins group A chip. What does this mean?

On the chip there is written: L6, 0690, 403, 3bar. The car has grey injectors and 3 bar map sensor mounted. It runs 1,2 bar (17.4 PSI) of boost.

When the car was on a rolling road the operator said the car got plenty of fuel. So I have been thinking could that be because the car runs too low boost compared to what the greys and chip is designed for?

What kind of boost should I be running with greys, 3 bar map sensor, your group A chip?

The turbo is a Garrett T35 (a so called group A turbo) with cut back blades (8 degrees) and 360 degrees bearings (not sure if its called 360 degrees bearings).

Engine specs.

Engine rebuild less than 10.000 miles ago with the following specs.

Ford Motorsport 200 block with long bolts
Group A dump valve
RS500 Intercooler
3" Mongoose exhaust
4 layers WRC head gasket
T35 turbo with 360 degrees bearings
Original 2wd or 4wd pistons machined to 7,2-1 compression (the pervious owner don’t remember if its 2wd or 4wd pistons).
4wd exhaust manifold
New 2wd head
New crank

Complete inlet manifold from escort cosworth with 2wd Idle Speed Control Valve (VAE-01) - Throttle Position Sensor PF09 (is this a 4wd sensor item?)

2wd L6 ECU
Greys
Chip, COLLINS GRUPPE A
Spark plugs, CHAMPION RACING 296 C59CX
Water thermostat housing from a RS500

The car has trouble starting. I mean it starts fine but after a few seconds it goes out – this goes on until its warm (driven about 1 mile) – Could that be because it has a PF09 TPS? - And sometimes it misfires when driven hard.

I really hope you can help me.

Thanks.

If it is running a 4wd TPS(PF09).Then it is NOT running a L6.As i think that only L8 and above use these.Wot colour is TPS.Red = 2wd black = 4wd.
To check ecu.Has the ecu got wings that you use to locate in dashboard or is it square.If it has no wings then it a L8

And i think for greys with that spec you should be running around 25psi if not more.

........if you swap the wires round i beleive you can run the 4x4 TPS on the L6...not a good idea though!!!!

If its just plugged in as normal youd get full fuel at tickover...could be your symtoms...i dont know.

You could run up to 2bar on your set up!

Give Collins a ring on 01260 298532

Hi

On the TPS it says PF09, and I it is red.

The ECU looks like this:

I had the car on a rolling road. The operator swapped the wires around, but that made the car drive very badly. So I swapped back and now it only goes out when the engine is cold.

He also said something about a bad engine sound, like pistons slap.

1,7-2,0 bar sounds like fun (25-29 PSI) J - can the turbo handle that kind of boost?

there's a very useful webpage here, that tells you about different ecu's and how to identify them and how to set up the TPS.

hope it helps you.

if you have a L6 ecu, you MUST run a PF01 TPS. PF09 is no good, and will give you idling problems.

foreigneRS

the colour of the TPS is absolutely NO indicator of what it is by the way. when fitted as new, both PF01 and PF09 were red, but some later service parts were black. you must read what it says on it (can really only by removing it, or the whole throttle body). and it must be setup correctly as per the instructions on that webpage and in the YB engine service manual available online.

SørenBM

foreigneRS> I have had the hole throttle body removed, and on the TPS it says PF09 - And yes I have idling problems... So it seems a PF01 will solve all my problems Really hope so.

Btw. YB engine service manual> do you have a link?

Thanks

Cheers Søren

SørenBM

ForeigneRS, according to the link you gave me I have a L6 ECU.

Cheers, Søren

SørenBM

Ima-Racing500> what do you mean about "If its just plugged in as normal youd get full fuel at tickover"? - Sorry, but what does "full fuel at tickover mean"?

Cheers Søren

alan rainbow

ima means that even the throttle is shut the tps is tellying the ecu that it is wide open so running full fuel

foreigneRS

so you have a L6 ecu, you mst use a PF01 TPS, and check that the wires to it are the correct way around (by using the electrical diagram available on the link that i posted above and their advice for checking resistance).

all wiring diagrams and the YB engine service manual are available in the Tech Essays Archive of Passion Ford (you'll need to be a gold member to enter).

SørenBM

Great, thanks... Just gona go finde me a PF01 then

Cheers, Søren

DanS

can I have your PF09 TPS?

SørenBM

Sure. If you come and pick it up at my place.

Btw. I'm from Denmark

Or do you have something interesting for a cos 2wd, perhaps we could do an exchange.

Cheers

Sorry, but gotta highjack this thread, but just by a little..
I have a 3dr with parts from all around the world or so it seems..
When i rebuilt it i found a chip marked "4x4 Sierra STD" or something quite similar in the ECU but i reckoned someone had put it there in the lack of a 2wd chip.
The 4x4 chip were limping and had a broken foot so i replaced it with a STG1 Collins chip for a Level 6 ECU..

The car is running quite good on full throttle and since that's what really matter i kind of figured it was ok.. It is not running smooth on idle and idle speed is approx 1500 rpm, got it down from 2000 though..

After reading this thread and how to identify ECU's i checked and yes, it seems i have a 4WD ECU.. even the green one..
The code on the ECU is: IAW 048/01 WD48.08/L3H.93
and according to the website linked to that is supposed to be the 4WD ECU..

I'm not sure about the TPS and if it is a 4WD or 2WD item.. will check it though.

So here is the real question.. Can i still use the ECU on my car and just get a 4WD chip, and maybe a new TPS, and then i'll be fine or do i have to change the ECU to a 2WD?

The car is actually running with the Level 6 chip and have done so the entire summer..

And yeah, since this is my first post or something here...
Hi y'all

foreigneRS

Hi Rob.

I'll be coming to Norway for the Gatebil weekend in September. Staying in Oslo on friday, saturday, sunday nights. Any tips for cool things to see?

Regarding your problem. It really is quite simple.

If you have a L1 or L6 ecu, you must run the appropriate TPS (PF01) and chip.

If you have a L8 ecu, you must run the appropriate TPS (PF09) and chip.

You need to check your TPS to see what you've got, but your best bet is to keep the L8 ecu, check that you havea PF09 TPS (or get one if not), and fit a L8 chip (personally i would go for a stg 1 chip from Stu @ motorsport developments with closed loop lambda fuelling and fit a lambda sensor in your downpipe if you haven't got one already).

what you also need to check is your TPS wiring. I assume that you have the original engine loom from the 3 door? this will be wired up for a L1 and PF01. To use a L8 and PF09, you must swap around the outer 2 wires on the TPS connector (or at the other end on the ecu multiplug). the website i linked to above tells you what kind of voltages / resistances you should measure when the wiring is correct.

hth.

Hi and thanks

Regarding your weekend i Oslo.. depends on what you wanna see, really..
If you wanna see crazy people driving the shit out of their 5-800 bhp car, nice ladies, and.. the downside of the show, drunken teenagers walking around the you should stay on Rudskogen as much as humanly possible.

I'm not really sure if i want a STG1 chip because it is getting quite boring
but i am concidering rebuilding the car this winter (again) and seamweld the chassis and get a full rollcage and so on and so forth.. it's all about the money.

But the way to go is getting a L8 chip, the right TPS and a lambda sensor?
Is the L8 a better ECU? silly question as it has a 128 kb memory but does it make any real difference?

foreigneRS

you've kinda answered your own question about a L8 ecu being better. i don't know, i've never had a L1 or L6 to compare it to.

i know what you mean about stg1. i've just gone stg 2 (greens and 3 bar MAP but still on t3) and it's so much more. whatever you decide to go for, stu will be able to do it with closed loop lambda control so that you still get good economy etc.

robhaugen

Ok.. so it really doesn't matter what ECU i've got as long i got the right chip..
How is the STG2 (on T3) compared to STG1 ? much better?

Good economy is..err.. good so i will get hold of a chip that will fit the ECU but i probably won't do it until winter kicks in..

foreigneRS

23 psi is a lot nicer than 15 psi but i've got so much grip that it still doesn't really break traction in the dry in first gear (unless launching of course)

was certainly interesting in the rain this morning
