FIAT CINQUECENTO 170 Wiring an MPI unit into an SPI ECU

Hi everyone. I was reading somewhere that you can take a punto 75 head complete with 75 cam fuel rail throttle body and injectors and wire it into the standard SPI ecu . Can this be done If so how difficult is it Cheers everyone Ben

Because it will make it MPI instead of SPI obviously S Im not planning on doing it i just wondered if it is true what Ive heard.

who said this link to thread in question

the connectors on the TB are the same and if you were the 4 injectors into the connector that used to power the single injector then it will run Originally Posted by ronnieronson whats the point much bigger ports for one.

FIAT CINQUECENTO 170 Replacing ECU - Seicento

Hi i might be picking up a 2000 Seicento SX today with an apparently diagnosed coil pack failure. I understand this could be a sign of an ecu fault (thanks Ralycinq) so am considering how to go about fixing that. Ebay seem to offer quite a few from varying models. Should i look for an exact match ie 1.1 non-sporting should i think about codes and immobilisers. Is there a safe way to do this with a 2nd hand ecu thanks for any help James

If you get the car...look at where the ecu is...what type and number before you ring anybody. As the ecu type and harware numbers are important as some of the earlier ecu s when they give this problem just need replacing with later ones fiat dealers automatically supply them under the superceeded part no. Again depending on type repair is not possible as they are small sealed hybrid units alledgedly

FIAT CINQUECENTO 170 Misfire on centre 2 cyclinders MFI ECU IAW 59F.M7

I understand this is a common problem where one pair of cylinders corresponding to one of the coil pack misfires. I get a fault code of P0352 associated with Ignition Coil B errorfault. I note that if the ecu believes there is a misfire then the fuel injectors on that pair of cylinders also stop injecting. In this case I have a spark on 2 and 3 but seemingly weaker than cylinders 1 and 4. I have swapped

This is a common problem on both Cento and Punto MPI ecu s. I have heard people claiming you can pop them open and are likely to find a burnt track (all though it sounds to me more like a transistor issue). I wouldnt recommend this though unless youre a dab hand with electronics. Plenty of places repair them. Ive always used ecu Doctor in the past Ive never sent them a fiat unit though so it would

im about to turbo charge a 1242 16V engine. fairly low blow. im using a garrett t15 with a 1.2 or 1.3mm decompression plate. i want to have around 7-8 psi max. so not high boost. i will also be fitting an intercooler and oil cooler. my question is .... how do i increase fueling when the turbo is on boost do i have to run the car on a completly new ecu . (megasquirtemerald etc...) or can i just have

The 1368cc na run a CR of 111 The 1368 turbo units run a CR of 9.81 The 1242 16v sits roughly in between with a CR of 10.61 It may be possible with proper setting up to run without decomp plate like Aaron suggested. Another alternative is to get your block bored out to 72mm if feasible and uses the fiat bravo T-Jet pistons Think they are about &163200 iirc you can use eper to check. Not sure how much

FIAT CINQUECENTO 170 Central locking Unit

Hi My car has a central locking on it but it doesnt work from a distance. If I try to program de IR sensor it reacts on the key. The previous owner had a alarm on it but did removed it before I buyed the car. I want to check the wires but where is the unit that controlls the CL system. unit between the sensor and door system.

The unit for the anti starting meganism is missing. This should be under the ecu unit. The connector is there but nothing else. The cap that placed on it has some bridges in it. When I remove the cap the car wont start anymore. This is the same connector (the one next to it) that is needed for the last wire of the IR sensor. When I bought the car the man said to me that the locks were broken and that

Hi Today I went to some fiat dealers and they all came to the conclusion that the system isnt available in the netherlands. So If I want to get some more info over this system I need to go to a german fiat dealer. This unit is also a alarm system i think. Thats possible the reason that 1 wire of the CL goes to this box. This is to activate the alarmstart blocking system when you close the locks. Does

FIAT CINQUECENTO 170 Concerning ecus

Hello everyone I have finally had enough of my cinq and its 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 its just this starting malarkey I have to get sorted. On the 900 ecu she fires first time

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 its 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

Fuelling Fuelling is bit of a more complicated beast even if the Auto Calibration (AC) is not taken into account. For this part lets assume there is no Auto Calibration of fuel active and also that the lambda sensor is not providing any feedback (this is for example the case when the engine is cold or the sensor is brokendisconnected).

FIAT CINQUECENTO 170 Changed IAW16F.ER ECU how reset key code

I used the soldering to my cinquecento Sporting without unconnecting battery now I have the ignition light always on. I changed the ecu with a second hand one (ignition key is ok so Im sure the old ecu has burned) but I havent now the keys. I opened the ecu there is a 8 pin SO package chip with this marks L9107 ST 9622 I suppose its the EEPROM containing the IMMO code. How can I reset the chip to use my own old keys Thanks.

Are you sure its a fried ecu These are pretty robust basic units that usually require outside influence to damage. Cheers D

MF2 doesnt get wired into ecu its a stand alone injector driver unit. It takes a feed from rev counter at back of instrument binacle it also takes a ve feed from ignition and a earthed behind instruments. You then need the 2nd MAP sensor that has three wires that tell the MF2 when ve boost is achieved if the MF2 has been used before in this configuration then it will recognise this if not there is

FIAT CINQUECENTO 170 Seicento Mk2 MPI - IAW 59F ECU Advice

Hi All Im currently running my Seicento P75 engined track car on its standard IAW 59F M1 ecu . (Magnetti Marelli Micro version) Now while its running reasonably well Im very aware that the ignition and fuelling map files are for an 1108. (I know I could remap the existing ecu but Id like to explore all of my options first) So my question is please What have people done with the fiat IAW 59F ecu when

The swap is great there is quite a difference in power and acceleration but the ecu is holding the engine back. Not to mention that it decide now and then to crap out because its picking up something different. I think the later ecu handles the 1.2 16v engine much better from what kritip said. I spoke to a couple of places to find out about a remap and they took one look at it and said that it cannot

FIAT CINQUECENTO 170 IHI RF3-PID Fiat Turbocharger Unit

Yep its in the classifieds and im going to have a look at it. Its off a PG 1.4. Anybody have any details about it. What type of turbo what kind of power could I expect Obviously I know Ill need a lot more bits but seems a good oportunity. Cheers Kristian

I dont know much (or anything really) about the 1.4 GP turbo is it from a T-Jet or an Abarth From whats been said so far it would appear that the stock charger on the T-Jet is limited to circa 150bhp due to internal restrictions. The stock Abarth unit produces a further 10bhp above the T-Jets max figures prior to mapping - Although the ecu has been the stalling point for tuners so you should be able

FIAT CINQUECENTO 170 Will cinq 899cc ECU work as ignition only

My fiat 850 has the most unreliable igntion in the world and it is making me tired replacing bits all the time. I did think I would swap the whole engine with a cinq 899 including injection (same engine) but I dont want to lose the carb and the performance of the high lift cam plus have to fit bits for injection. Current engine already has cinq bottom end and has hole on timing cover for crank sensor.

get back to your panda 100hp If you go for megajolt it can use different wheels but will be a lot of work to fit due to additional sensors etc. Bolt a ford edis unit it without an ecu will only spark at 10 degrees though and will need a 30-1 afraid i know very little your hardware setup or the car so dont have that many ideas.

FIAT CINQUECENTO 170 Cinq. Sporting ECU Swap

I have a 98-reg Cinq. Sporting - which is highly likely to have a soldered chip in the ecu . My local breaker has a Punto 55 in at the moment so I was wondering if I could use this ecu on the Cinq In know the Punto 55 ecu has a lower rev-limit than the Sporting ecu but Ill be taking the chip out and replacing it with my Superchip which also disables the immobiliser. Dont want to buy it if its not

Had thought of that.... but Id prefer not to touch it - still want an ecu with immobiliser for when its garaged (I have a rented unit a few miles away) - and one for the track.


Hey Chaps Until reading the fuel implant technology manual for the DET 3 found here httpwww.ecumaster.comdownloadDE...nt_english.pdf I had no idea it was capable as acting as a stand alone fuel system while retaining the original ecu . It is seemingly is quite cable of converting an SPI Cento into an MPI with little more than the addition of a MPI manifold TBinjectorspump. This would be great for me
