Hello all,
Right, wow its been a while since i have last logged onto this website haha... ok now i have a problem with my 1.9 JTDm Sporting.
I have had a look around a few threads and non of them really seem to help with this... so here is the test, can anyone shed some light on this matter....
Right, my story starts:
I bought my lovely black 1.9 JTDm Sporting about 1yr ago. I then did a bit of research, and decided i wanted to get my new car re-mapped. So i booked it into R-Tech (heard lots of good things about them) and they RR'd it, wrote a new map for the ECU, then RR'd it again and I was highly, highly impressed with the outcome... just short of 170bhp! :slayer:The novelty of having so much power and torque for the last 6months has only just started to die down... (don't get me wrong, i still love the fact that i have so much power in such a small car, but i for some reason now crave more...
)
I got my re-map done while my car was completely stock, as i thought to myself "nah, i'm going to keep this one standard...Just the re-map will do..."
How wrong i was, as now my car has a performance air filter and new stainless exhaust system. So after buying my re-map, i then had these two nice little mods done with the intention of going for Stage 2 re-map afterwards. ( i haven't yet gone for the stage 2 )
At this point, all was running well, my car was quick, smooth, economical and just all in all a blast to drive. I loved my car at this stage...
Ok now is where it all starts to go t*ts up... I then realised i'm wasting time and money if i go for stage 2 re-map without doing all my performance mods i want to do first. So i then did a bit more research and found out that releasing back pressure by removing the cat converter from the exhaust system apparently helps with bigger power gains...
Got this done, its now running a de-cat pipe on the stainless exhaust.
Again, all was running grand, smooth as anything, no real gains or loss in power, just a nice tone from the tailpipe when i accelerate.
Then, i drive home from work one day and come off the motorway. At the bottom of the slip road is a set of lights. I stop on red, come to pull away on green and the car all of a sudden has literally no power what so ever... nothing right up until 2000rpm... at 2000rpm the car judders and splutters then the turbo kicks in and we're off and away again like nothing happened... since that moment, my car runs fine when the turbo spools up and kicks in, but at low engine speeds i can literally put the accelerator down to the floor and it does nothing, climes VERY slowly, splutters, judders, coughs out plumes of black smoke all the way up to finally reach 2000rpm where the turbo seems to kick in and then rip my face off...
Below 2000rpm, it almost feels like its misfiring/running on 3 cylinders, hense the lack of acceleration at all. Its even threatened to cut out on me once at a junction.:bang:
Its not the head gasket going/gone because A: i presume my car wouldn't even be running would it?! and B: i have checked my coolant level and also checked oil for any tell tail signs of the head gasket leaking coolant into it... nothing, everything seems to be in full healthy order there.
I'm now left baffled as to why one day with my de-cat, exhaust, and performance air filter and my very first re-map everything was running fine, sweet as ever. Then all of a sudden, no power at low revs, no throttle response at all... and a slight hesitation to go anywhere as i move up through the revs towards the turbo range.
Can anyone shed some light on this matter, as its completely baffled me and i don't have a clue what it could be... do you think it could just need the stage 2 map... kinda like it needs to adjust to all the new mods??? Or does it sound like a mas air flow sensor problem? or something wrong with the injectors? Like i said, i haven't got a clue now...
Please please help!
Cheers,
Sean
