Well here is the story, had my 1.9GP remaped last october by Derv Doctor in derby, the car was great after, i was well pleased with it. i have had no real major problems with it. Until yesteday when i was driving along in a 40 and my car completly cut out. so i took it down to the local garage by my work, ran a diognostic and its brought up 3 codes all for injectors. the codes got deleated and the car was running fine, until this morning. it cut off on the way to work 5 times. ( i work 1 mile from my house and it took 25 minutes to get there). we got a bloke to come down and put my stadard map back on it, while he did that it came up with 3 injecor electrical errors. my car is still under 3rd year warrenty, do you think fiat will detect the map o be suspicious and refuse to replace them? i hope they dont because each injector is £250
 
i dont see why FIAT should pay for them, an injector is meant to run around 80% duty cycle, if the map has pushed it beyond that.. then how is that fiats fault, why should they pay?

:yeahthat: Unfair to expect Fiat to pay for something you have caused. Sometimes its hard enough getting a genuine claim passed let alone self inflicted damage, IMO
 
no real figure was proven, bout the guy who maped it said about 45 hp increase. the other bloke who put it back to standard said that the fuel pressure was to high
 
ye your all right, to be honest i fink i will end up paying it anyway, the bloke at the garage said that he can get 1 injector for £250. wonder how much fiat will charge for all 3 of them + labour
 
Don't fall into the trap of replacing parts because "that's what the diagnostic machine said". Just because you have injector fault codes stored doesn't mean the fault could lie in wiring issues or even the ECU. Bear in mind also that if injectors are replaced the ECU will need their individual codes written to memory to ensure the correct fuel delivery.

And the chances of 3 injectors failing together on two separate occasions is somewhat unlikely.
 
I agree with the above, the injectors are a mechanical part, and to have 2 go on neumerous seperate occasions is a bit weird, Id be checking the electrics before paying £250 a throw for injectors,

If the map was put on the ECU correctly I think im right in saying most tuners make it "invisible" If you have the standard map back on now Id take it back to Fiat and be cheeky and ask, I would think as it is a major component of the engine it should be covered.
 
the standard map is on, and the codes have been deleated but the car still misfires. i noticed a rapid drop in fuel consuption over the last month, it was averaging about 30 and that was driving normal. also sumtimes it struggled to start in the morning, giving off alot of white smoke when it did (unburnt fuel). it was like the injectors were leaking fuel.
 
it was serviced when i brought it in october, and i got it seviced 4 weeks ago, had the lot done even gear box oil.

just been on the phone to fiat and they have quoted me £742 to sort it
 
My wifes Seat had similar problems all pointing to mechanical failures. Based on the my local independant garage diagnostics it would have been all too easy to replace lots of mechanical parts and still not solved the problem.

Eventually went to the dealer. It took the dealer hours to trace the fault, which came down to an Ecu fault which was eventually replaced.

As has been said the remap may have upset the Ecu. The dealer is probably best placed to diagnose the fault properly.

Whichever way it sounds expensive. Best of luck.

if he is from same company and admitting that they set it to high then give them the bill, a rolling road would have shown you the fueling and could have been tweaked down if needed.

fiat dealer will still know them codes have been there even if they are deleted, it just makes their job of finding the real fault a bit harder if you delete them
 
thanks for that mate, i have booked it in for monday 18th may, i go on holiday next wednesday so im just going to wait til after. hopefully they can tel me exactly whats rong and put it right.
