Hello everyone, I have finally had enough of my cinq and it's poor starting. So I have swapped back to the 900 ecu for now.

If I turn the key the fuel pump runs for a bit, turn one more click and she turns over but takes an age to start. I have an iaw16 er-f ecu with a gazzaman chip. Once running, she is bang on. But it's just this starting malarkey I have to get sorted. On the 900 ecu she fires first time, and after a couple of hundred miles from first being connected settles down and runs fine, albeit not as nice as with the 16 er-f ecu.

Am I using the correct ecu? I have a chips2race chip, but this doesn't work. I assume it doesn't bypass the immobiliser. Woj has offered to bypass the immo circuit a while ago, but I just want to make sure there is nothing obvious I am missing?

Cheers Huw.

Nothing I can think of.

I can't see it as an immobiliser issue -- either it'd work or not.

You'd expect it to run very lean on an 899 chip, but........

Apart from the old thing of a less than optimum engine temp sensor (in which case why does it start OK with the 899 chip?) I'd think a chip or ECU issue.

You might be able to dig up an original chip and try that, otherwise I'm stumped. Wrong values on cold start (on chip)?

Woj -- and maybe only Woj! -- will know.

And the engine is (my memory fails me)?

When do you feel it is struggling? The very first bit of getting the engine to rotate, or the second bit to get to the right tick-over speed?

In essence, the problem is probably down to fuel or ICV operation. Fuel has the settle-in option, but not for the first state of starting, cranking that is (hence my question), and ICV does not have the settle-in option at all on this ECU, or at least I guess so, I never really looked into ICV-s on these ECUs 1(16Fxx-s that is).

The engine is a 1.2 8v Punto lump, with a 32mm spi unit.

The ecu does not work at all with both the original chip, and the chips2race chip. The fuel pump does not kick in at all. The gazzaman chip does work and very occasionally it does start first time when warm, but it's like once a fortnight.

You turn the key and the fuel pump primes as normal, but then you crank the engine and nothing for 6 or 7 seconds just the starter turning the engine over. It will then start and run fine. It does give a cough and splutter temporarily when the coolant is at 60 degrees Celsius then clears and is fine.

With the 899 ecu on it, it starts great first turn of the engine and no splutter at 60c. It's just not quite as powerfull or reponsive as when the 16f ecu is on it. It is really annoying me because others have used the gazzaman chip with no issues. Do you think the same model ecu but with a different code would be any better? Obviously the chips2race chip doesn't bypass the immobiliser side of things. Was an ecu produced like this one but without an immobiliser circuit?

I know woj has kindly offered to bypass it for me, but personal finances are a bit tight at the mo.

Need to know more about the engine (size) and any mods.

I think very, very early 899 ECUs have no immobiliser. Finding one, though..........

wasnt it prior to 96

Earlier than that, I think.

A few other thoughts:

1. If the 899 ecu has a removable chip (and I'm presuming here, that you're swapping whole ECU's up to now) swap with the modified ECU. This will rule out issues with the base ECUs and the chip.
2. There was a guy in Israel doing chips. Is he still about? They were pretty cheap.
3. I'm very sure you can still get mountable chip carriers.

Unfortunately it's a fixed chip in the 899, d'oh.

Ye the chips2race chip was from Israel.

I will look for another iaw16 with a different code at the end.

See if you can find a chip carrier, make the chip transferable. I think I've got a spare carrier (came with the Volvo) might be the same, but they shouldn't be difficult to find.

have you changed the fuel pump? the 1.1 spi only ran a 1 bar pump iirc but the 1.2 run a 3 bar pump.

Only the MPIs run 3 bar, I think.

ive noticed that with the Mckritch chip in a spi siecento ecu it takes longer than it does in a cinquecento ecu.

happens nearly every time without fail has to crank for like 4 or 5 seconds then starts, then with the same car stick in a cinquecento ecu and its first time every time.

I have no idea why this happens. Just something that we've noticed.

My advise is to have a good battery

Eklipze3k's sei takes ages to start with its mcKritch chip in it, just turns over for a good 5 or 6 seconds before it fires up, but starts fine once warm. Starts on the button as usual with its original chip back in :shrug: There is nout wrong with the car for sure, i just put it down to something not being quite right on the chip.

Could you not just get a 1108 spi or 1242 spi ecu complete with key and codebox from a breakers or something? If your lucky you could get ignition barrel too but if not just leave the key that matches the ecu behind the dash near the receiver.

Jiminwatford or Puntospares could prob sort you out

Had the exact same problem... my old sei had this issue.. pissed me off so much in the end I bought a mckritch chip.. gazzaman chip was the one at fault for me mckritch was perfect.. Id assume you have the gazzaman chip... also the chips2race or whatever they were called had the same issue from what ive heard..

Mine is a gazzaman chip. First start from cold takes 4-5 seconds. But even if it isn't warm and you turn it off after a few seconds of running, it'll start again immediately on the key. Thought about getting a mckritch, but worried that they had the same issue.

i tried gazzaman and it took a while to start.

mckritch started imediatly

That roughly tells me that whoever did the map in the gazzaman chip (and I think that was not gazzaman actually, I think he got it from some PL site) had little idea of what he was doing. It means that "accidentally" either the cranking fuel was changed (don't believe so, nobody apart from me knows where these maps are, and they are very forgiving anyhow), or the cranking ignition, or the main duty cycle table of the ICV. The last one is very likely, as in some ECUs this table looks very much like the main fuel table.

In any case, I think I should have the gazzaman chip's image somewhere on my disk, if so, maybe I will find the time to look into this (just because I am curious).

EDIT: Actually, I do not have gazzaman's chip in my repository.

Anyhow, this brings me to another thing, but I will post in another thread.
