I had my 2006 Skoda 2.0TFSI remapped just after xmas, and since its been remapped its starting to misfire at about 3000rpm, and it just does not feel as quick as it should do at all.
I took it to Midland vw for them to plug into the OBD port and then took it out for a spirited drive, the only fault was the MAF sensor was peaking at 160 then dropping down to 130, so i fitted a brand new MAF that i bought from the stealers, this made no difference at all.
I have also fitted a new revised diverter valve, as the one that came with the car was the original one.
So my question is, could this be the MAP that is causing these symptoms?? as the car was fine before the MAP was installed.
I'm not going to mention who did the MAP yet as i have used him before with very good success, and he is well known in the BMW scene.
thanks

You really need to do some fault scanning and live logging to narrow down the problem. Plugs or coil pack are the usual suspects.
That being said, shouldn't your tuner be helping out here seeing the misfire didn't occur till the map was applied.
-
My bet is the extra strain of the power has caused a spark plug to go.
-
Which map is it?
Can you put back to standard and test?
As said, worth hooking up to VCDS to see which bank is misfiring and swap out that plug out to test; then coil pack.

well just ordered some new standard plugs so will put them in on tuesday.

The guy who did my MAP is away till mid february, so just thinking what it could be, and i like to get my hands dirty, but when it was at Midland VW they did the live logging and the only fault was the MAF.
-
Was the map just a generic ECU flash, or was it dyno tuned or at least datalogged?
-
According to their website they are recent Revo dealers but previous to that were Custom Clown dealers.
If they put Custom Clown software on your car no wonder it's misbehaving. :scared:

That's Midland VW isn't it? I think the OP is saying they didn't map his car.

Are they well known for remapping BMWs in the Wolverhampton area?
Are you sure it's a misfire? Is it random or being logged in the same cylinder?
-
The MAP was not done at Midland VW, i only have high praise for Midland vw.
The MAP was just one that was loaded onto the ECU after the ECU's standard file was downloaded, and then sent via email for the MAP to be put onto my ECU.
I'm waiting for the guy who did my MAP to come back of he's hols and get it either sorted or refunded.

Its not logging anything so when i took it to Midland VW all it showed was the MAF sensor not operating 100%, with no faults at all.
Its reving to 3000rpm and then misfiring/bogging down, it wont rev for about a minute then it revs cleanly as it did before the MAP.
-
About a minute, or briefly... perhaps the map is running lean.
-
So your map was uploaded without any datalogging, and the map was emailed to you? Id say thats probably a key problem there in its own right. I don't get why you dont want to say who did it, you never know someone else might have heard of them and will be able to help.
Ideally you need to log the car find out what cylinder the misfires occur on, swap the plugs and coilpacks around then try again. Then if the misfire changes cylinder as well you've narrowed it down to a spark issue, if it stays the same its probably a map issue.
What blocks are you logging?
-
ok it was EMAPS who did the map, Simon came round to my house plugged in he's laptop and made sure there was no issues with the car and then emailed the file over to he's business partner, who then changes the files for the ECU, it was then emailed back over and then flashed onto the ECU, not unlike most places that dont have a rolling road or a custom remap.
He did my old E46 330d a few years back and that was incredible after he did that.
I will let you all know what the outcome is, but he is a nice guy who will sort it out.

What is the advice we give on the forum? Always go to a reputable TUNER that is well thought of on the forum :happy2:
The setup you have described sounds a lot like these cheap remap places that have no understanding of how the TFSI engine works, they simply tweak a few factors in the ECU map to increase boost etc and leave it at that.
I thought this was the case as the OP was reluctant to reveal the "tuner"
@OP I think you ought to take it to a specialist (one that is on the forum) and get it looked over :happy2:
-
Here's a recent article I was involved with for Sedox:
http://news.sedox-performance.co.uk/2013/01/why-dyno-tuning-is-so-important-during.html
Files being emailed back and forth, no real tuning or at least datalogging.... I've seen map files be corrupted by email virus checking systems many times. :sad1:
-
ok i should have listened to my gut instincts and gone to R-tech then, which i was going to do, but after emailing twice and phoning them about 8 times and leaving 3 messages to which i never got a reply. Ok it was just before xmas but still a phone call back to say sorry we are busy at the moment would not have hurt.
So if i cant get it sorted by Simon, i will try and take it to Shark instead.
-
^^ R-Tech are difficult to get hold of. When they are using the dyno you can't hear the phone ring :grin:
You have to try early in the morning or keep trying throughout the day. Their services are in huge demand so hundreds of emails they can't always answer :sad1:

I had my first map done after I read recommendations on this forum and elsewhere. It was a terrible map and I changed for another.

9.30am to 4.30pm 6 days as week the dyno is running non stop. There is only 2 of us here running the show, one to tune cars and one to reply to emails and calls between jobs. Everyone will get a return call if they left a voice mail, the only time they don't get a call back is if we cannot clearly make out the phone number left in the message.
We don't ignore calls or emails. Just struggle to keep up and end up with a back log.
To get a booking you need to keep trying to catch us when we not on the dyno.
Update: I have found the email you sent via the website on the 26th Dec, we replied to this 28/12/2012 at 12.59am, but no reply back. have you checked your junk mail? and 4 phone calls made to mobile number ending 245?

Hi Nick,
thanks for the pm, and i have replied to it, and i do understand you are/were very very busy so i was in no way having a go at all.
But i do hope you can help me get my car running right.
today this is what happened
Had the guy who did the remap come and look at the car today, with he's map on its showing 1.1bar, but then for no reason at all the shooting down to 0.6bar, the car was logged and the only thing he noticed was a fault saying bank 1 running lean??
I have fitted the following items since he did the remap to try and fix it myself.
1, new standard plugs.
2, new revised DV.
3, new autotech cold air feed.
4, new BSH PCV fix.
also with he's map on it showed 225bhp max, he normaly gets approx 240bhp from out of these, and with the map off its only reaching 185bhp
-
Injectors??
Actually perhaps the standard plugs can't cope with the upped boost.
-
The oe plugs are more than fine for stage 2+ applications. Mine never missed a beat at that level of tune.
-
Can i just add about E-Maps WORST remappers ever!!
I had a 525d that ran absolutely fine, visited my mate in Leicester so a hefty drive from Falkirk, Got Simon to meet me at my mates garage, he done a scan all was fine then uploaded the map, car struggled to start then when it did it was hunting terrible.
My mate took it a run said it drove well but idling funny and it could be a maf, anyway drove back up the road hesititating like hell call'd simon who said it wasnt the map but possibly a camshaft sensor or Maf.
got it home at 1am took it to my local garage at 9am who done a scan and it came up with
Glow plug controller
all glowplugs knackared
camshaft sensor
Maf
In total cost me 2k to fix and have the map removed was a total joke, i wouldnt trust him or his dodgy german maps as far as i could throw them.
AVOID is my answer.

Hello,
How is he recording the BHP numbers?
With the right person and the right logging it will be easy to find out where the fault is.
First thing is the lean fault, ADD or MULT? this will point to where there car is running lean on idle or under load/cruise. If they are not VAG specialist tuners then I could be hard for them to pin point the exact issues. It could be a mistake in the mapping or a hardware fault with your engine.
IMO your best bet is get the car set back to stock with the factory map loaded then run and log the car to make sure the stock numbers are correct and more so the engine hardware is running correct and safe.
Give Ben a call or email at the workshop and tell him you want to book in for a full health check session
01455 617233 if we are on the dyno just leave a message and Ben will call you back later on in the day or 10am the next morning.
