Anyone using a motel on their sierra cosworth

My car is using the 8 injector kit , with GT35 Turbo and a Motec Ecu and it can't boost pass 0.5 bar .

Anyone can share how to get this rectified .

jsa

Not me, but get on too the motec.com.au forum.

Can only be setup or wiring issue.

I am about to set up an M800 on mine, we should share info... There are some guys at motec that have YB's but they are NA not turboed. Mine will have GT35 also.

Take it to your tuner. Unless it has a very weak spring in th waste gate you have a air leak.
You need to look at what your ecu is ment to be targeting and then work out if you boost valve is working.
And there is to little info on what you have said to be able to help you.
Has it been mapped and how long and was it ok before.

Hi Guys,
thanks for the replies

Mark,
It was just fixed and my tuner said it has to do with the wiring and fuel . Thats why I am asking if anyone has used a M800. I am sending it to the wiring shop to check whats wrong . Car has been acting strangely and the interior gauges ad battery connection goes off when i drive in the rain and have to call a tow truck.

Ooho,
Looks like we are heading in the same direction mate. Do you have your old ecu and loom? I am in need of one as i sold mine off and would be selling the cossie after this as I have a baby coming up .
This is my first cossie .


Jsa,

any idea if the motec would still require the fuelling ecu to be installed or would the Motec eliminate both ecu's.
For wiring , what would you check?

Thank you guys as i am based in Singapore and we don't have many cosworths around . Less than 8 on the road including the Ford Escort Cosworths.

jsa

M800 will do it all.

Map sensor & boost control solenoid for starters.

Sounds like you have bigger electrical problems, that need sorting 1st.

Not many cossies down under either.

Mark Shead

As the Cowsorth car and engine is really basic in its control needs it cant be hard to find a tuner with a brain to work it out.

I have used the M800 on turbo engine's, although that were Porsche turbo's.
I did use a wiring similar to the Cosworth engine and even used the Cosworth amal valve (boost control solenoid), which happens to be a standard Porsche part as well.
I had no problems getting it up to the required boost.
I used a new wiring loom from Motec and made that fit the Porsche engine.
There's no need for the original ecu to be in the car, not with the Porsche and not with a Cosworth engine.

Wiring can be found on the Motec site.

Hi Mark,
car was sent to the spray shop yesterday and I can't seem to post pics of the car here .
Cars radiator didnt have water but after topping up at the spray shop, it was idling ok.

My Tuner said, it has to do with wiring. I am using HKS to control my boost .

I am trying to get the car out of the spray shop in a week and would send it to the wiring guy, hope nothing is damaged.

The car does take engine oil and i have to top up occasionally . Is it normal ?

SGP

Hi,
I am actually in Singapore and I am exporting the car to Sydney in the next 2 months as we have silly rules here in Singapore.

Yes, would ask them to check the map sensor and boost solenoid.

SGP

Hi Mark,
My tuner just tunes and he is travel all around the world . He has tunes my Porsche and my Mitsubishi Evo and we made good numbers .

In singapore , we don't have any good mechanics who can do Ford Cosworths.

My tuner said , it's probably a wiring problem.

SGP

Thank you Sir,
Do you have a base map you can share with me and another forum member .
What boost do you run at ?

Thanks

oldford

The Porsche engine is a 3.0L 4 cylinder turbo and runs a maximum of 1.3 bar boost with the standard amal valve and no external boost control (like the HKS you have). So there's little use for my maps here.

On Cosworth Group A engines I use up to 1.85 bar boost, but that is with air injectors and Pectel ecu's. Not much use for you either.

Mark Shead

A good tuner will know a good garage for you to get it looked at.

Mark

SGP

we found a wiring guy to have a look

and my tuner does 9 second evo's and 10s flat 997 on the drag strip

so i know he knows what he is doing.

SGP

You have your old ecu for sale? I am gonna switch back the car to normal spec and would use the motec on another car.

Mark Shead

I have seen the same in the uk and I know some of them have no idea what they are doing lol.

Mark

jsa

So the boost problem is with the hks electronic boost controller, or are you talking about a wastegate ?

oldford

No, these ecu's have been returned to the customers (if they ever had one).

Why switch back to a "normal" spec, whatever that may be?
The Motec is a very powerful aftermarket ecu, as long as you let it control the boost and not use external boost controllers.

Mark Shead

The first thing I would do is throw away the HKS boost controler these IMO are crap,
Find out why it did not have water in it.

Mark

I talked about this off line, I think the engine has a number of issues and needs someone that knows about YB's to give an honest review on what to do.
If anyone knows of someone in Singapore that he can go to I think it would at least give him an idea of what needs to be done.
Without it I fear a dead YB will result.

SGP

Thanks mate

SGP

I would be checking that out. I really not sure until next week when I send it to be checked .

SGP

I like blitz but it came with the car . I bought this car from a deceased friends estate . I am trying to sort out all the problems and go for a race and as that something my friend wanted to do . I only got the car for a week .

After that I am gonna export it. This car has a RS500 engine and many Group A parts.

I am new to this cars so pardon my ignorance .

I am grateful that you guys are kind enough to share information .

SGP

Anyone used L6 ecu ? And how do I get the harness if I am running 8 injectors ?

Car should be out on Monday after the spray.

Anyone knows if non paid members are allowed to post pics ?

You guys can see the leak here .

And I am still wondering what injectors I am using ,

Mitsos

Hi mate i can't see what injectors are you using, you need to take a better picture but is the wiring cut in the one off the injectors? You may consider taking the car to Syndey they have some great tuners there, also they know the yb engines and surely they know motec ecus. If the car was sitted in a garage for years maybe rats have damaged the wiring? This engine seems it needs some tlc

SGP

Hey mate,
Would take a better pic of the car , and would be getting all the wiring checked.

Greeces is lovely and are you from Mykonos

SGP

Anyone know where I can find a steering rack and also thermostat for the radiators ?
Car was overheating

jsa

Can you get a v12 jag thermostat locally ? Part number is a match.

SGP

Hi John,
So the thermostat for the Jaguar V12 is the same ?
What year jaguar. Pardon my ignorance

Is this the same thermostat ?

jsa

Looks right, I'm not familiar with QH part numbers.

If your buying from ebay US, may as well get one advertised for the cossy from ebay uk.

Thanks John

Anyone wants my 8 injector kit. I am going to be using the standard fuel rail with 1200cc injectors from Bosch .
