Poor starting and the mystery wire?.

Hi all.

In January I changed my ecu from an 899 to a 1108 with a gaz chip in it, Goes alot better but it is useless at starting. With the 899 it started fine, but now you have to turn it over for a long time before it fires any ideas, or similar experiences?

I also have a wire that has suddenly shown itself, it is in the passenger footwell where the loom goes under the dash.

It is unusuall because it is a black wire but coaxial with a red centre. Any idea where it goes?.

cheers guys.

Black with a red coaxial you say? Sounds like an audio cable.. Like the kind you'd plug into an amp from your head unit. Just a guess mind. Another guess, could it be the aerial? Not totally sure without a picture.

Re: Poor starting and the mystery wire?.

Hmm that is a shame, the car is lovely when running, just a bar steward to get going.

The wire isn't audio, because I have modified all the audio and not come across it. It isn't the aerial as that is connected and works. It is quite small, about the same as a bit of 5amp cable.

I will get the camera and take a photo.

Stay tuned folks.

Re: Poor starting and the mystery wire?.

well to start you are using a ecu that is not intended for the engine displacement and you are probably overfueling it

and as for the wire it sounds like a female coaxial often used as an extension and probably used by previous owner
i do audio installs and i've had my cinq dash to bits full loom out and i dont think i've come across this in the stock loom

"well to start you are using a ecu that is not intended for the engine displacement and you are probably overfueling it."

Sorry should have said, i'm running a 1242 engine with a 32mm throttle body on a punto inlet mani, no cat and an induction kit.

Are the gaz chips still self adjusting, or do they just maintain a given map?

As for the wire it is within the manucacturers loom. i've had two 899's and both were wired differently in places. For example my last cinq had proper side light, but this one has ballasted headlights on the sidelight function.

Re: Poor starting and the mystery wire?.

fuel pump is the same as the 1.1, so shouldn't need change for the 1.1 ..

I would try a different chip and see if it starts as normal.

Re: Poor starting and the mystery wire?.

That was one of my thoughts, but seems to still pull well on full throttle.

Just recently it has started cutting out, only does it once, about 5 mins into a journey and then is fine. Smells very juicey when it does fire up, but no injector light or anything. If you have a bit of momentum it will go again on it's own. Seems to cut then clear about 2 seconds later. No problem, just embarasing at traffic lights, especially coupled with the poor starting.

About a month ago the head gasket blew, weird as it was all skimmed and done properly last year, when I built the engine. It didnt overheat or anything, as it blew between cyl 3 and 4. Head was double and tripple checked for straightness as was the block, all is spot on. Must have been a poor quality gasket, i'm not convinced it was a 1242 one, think it might have been an 1108. Ever since then, it starts a little better when warm, but is the same from cold. Got spark from when it first starts turning so must be fuel. Compression is good and even on all four cylenders, I balanced the crank, rods and pistons, it also had a deglaze and new piston rings last year when it was first built.

Everything else is new, waterpump, timing belt, valve stem seals, valves lapped etc. So definatly something electrical. It's just very frustrating.

Re: Poor starting and the mystery wire?.

Ye ming, I might pop the 899 ecu back on and see what happens.

One of my earlier questions was wheather the chip is still intuative and self adjusting, if i disconnect the ecu and leave it for a bit would it reset itself to a datum and then learn from there, or are gaz's chips set to one map, and dont deviate?.

The cutting out thing has only been since the head gasket was done, i'm just wondering if it has tried to adjust itself, and not gone back entirely.

Re: Poor starting and the mystery wire?.

Ye, crank sensor came with the engine, just spliced the wires in with mine, are the sensors the same on the 899 and the 1108?. Different wires I know, but same values?.

Re: Poor starting and the mystery wire?.

Well when i fitted my mckitch, it started right away. And i also have experience with both gazzaman and chip2race chip taking ages to start.

Am sure that is because is a fault with the chip.

They don't really learn as such as i don't think the ecu is that smart i think it only allows small adjustment.

Yup try the 899ecu if it starts right away then that is your problem!
