Re: Fabia vRS
is it actually the map then and not something like a MAF starting to fail?

Re: Fabia vRS
oh i don't know. what causes the MAF to fail and what is a MAF? i've heard about them before but don't know what one is.

Re: Fabia vRS
the maf is the mass air flow sensor, it uses a hot wire inside heated by the ECU and monitored for how much the air passing it try's to cool it down to determine the amount of air being sucked in, they are common things to fail and normally lead to a lack of fuel being injected on turbo diesels when failing but there is a chance that the ECU will have logged a fault code, both me and ricky have reader that can check that for you
still think it could be a map flaw though that could be rectified

Re: Fabia vRS
as explained expertly by jay, im not saying it will be that but i just thought of that rather than the actual mapping,
it wont necessarily log a code if its not completely gone, and it sometimes still reads normal on say tickover, i was scanning a passat the other day which had a power loss problem, but just plugging it in and reading some live data it didnt show anything up, unplugged the maf and the owner drove it and said it had changed the characteristics of how it drove so they tried a new MAF sensor and it cured its power loss,
its not something i like to guess at really but if the company that mapped it will look into it then they should be the best people to tell you what it is causing the problem

Re: Fabia vRS
funny that rick, i tried a volvo 40 1.9dci that had no codes, it wouldn't rev up....with the MAF disconnected and it was okay, new MAF and sorted
Re: Fabia vRS
as much as all these modern bits and bobs help fuelling they can be a nightmare to diagnose, and it can end up being trial and error,
let us know how you get on anyway Ryan

Re: Fabia vRS
I've read that on Briskoda, someone said try clean it. I've had a word with a couple of guys on Briskoda who have the same map and they were put on the same day and they have no problems.

Re: Fabia vRS
yeah well said Rick mate, so true.
all being well ryan your man will have a quick look into the MAP and will sort it out but either way ill see you at the weekend looking forward to it!.......that'll get people thinking haha
btw most cases of MAP sensors failing tend to be internal or the hot wire itself rather than a build up on the surface but a spray with carb cleaner shouldn't hurt it.

Re: Fabia vRS
hmmm yeah see you at the weekend Jay, btw what day's best for you?
I think it could be the MAF with no one else complaining surely its got to be my car and not the map? i don't know confused.com

Saturday mate, i finish at 12 so from 12 on i can be at work ;0
best thing to do is get a MAF from one of your mates cars that you no is the same and see if it helps at all, with the dip in power and torque your getting you'll be able to feel the difference if it cures it.
there are other things that can cause this though such as boost control valves and boost pressure sensors etc, but like ricky says they wount always log a fault if there not broke so to speak. Ill scan it on Sat and see what it comes back with just for good measure
thanks

that would be good mate, we could run through some live data and see whats what on Ryans car??
Ryan90VRS wrote:I've just got my first star yaaay
Congrats lol
and i wouldnt worry to much anyway mate like we and Noble's said there isnt anything massively wrong but its just a flaw that could do with putting right to get the best from the MAP it would be noticeably quicker and smoother if it could hold onto the boost keeping the torque curve flat, even things like a split vac pipe somewhere on the boost control side can cause a drop in boost.

Re: Fabia vRS
you want to run my car for a week haha, you'd end up pulling over to call in for some matches and a can of petrol haha.
there's always teething issues with cars, they do it on purpose to keep you on your toes lol

Re: Fabia vRS
Somebody on Briskoda said it could be the MAF also someone saying could be un-stable boosting? he then said "It looks like the boost may peak and then drop off as the revs rise".

unstable boosting can be caused by map flaws, a faulty boost pressure sensor, boost control solenoid or even a leaky vac pipe mate, and me and Rick will check out the MAF best as poss for you on sat, i can test your MAF using a multimeter anyway
if worse comes to worse i can get hold of a new MAF for a good price through work to try
thanks
Re: Fabia vRS
were would i be without out you two....
i'm sure we'll (you 2) get to the bottom of it.
i've also been reading up about a decat and people are saying decat before remap and not remap then a decat why is this.

there are specific settings in modern diesel ecu to accommodate for decatting, im lead to believe this is because certain fueling characteristics that help the cat function can be removed when decatting and this allows more benefits to be seen. It wount hurt at all to fit a decat on your existing map, youll still feel benifits such as quicker spool up and increased top end pull etc.

i'm taking my car to shark performance on sat jay to let Ben have a look at the map. there's people saying on briskoda that the map is s**t and that the torque comes and goes too quick etc, i find the map is fantastic and its very smooth.
Shark Performance is a very reputable company with lots of happy customers and i've never heard a bad word said about them, i just feel abit bad because i don't want to put people off going to him because i posted the graph up from my car!

Re: Fabia vRS
i have first hand experience why not to map a motor then decat it haha, in my case its because the turbo now spools up so quickly low down it reads overboost and throws it into limp mode,
jay we'll have to sort out somewhere for me to go though on sat, cos of your excellent anti-low car scheme at volvo

thankfully this shouldn't be an issue on a Diesel VNT turbo though infact diesels tend to have a large boost spike as much as 0.2 bar in stock form , petrol waste gate types have to little control compared the VNT's
and you can put your car on Hawleys when they gone mate
