Recently had a quantum power remap put on my Seat Leon 1.6 Ecomotive estate
I've noticed it now has a surge/misfire hard to describe it,only does it very occasionally
Any ideas as to what might be the cause
Thanks.

Get it back to them! never heard of them though tbh and I have seen numerous threads throughout the years of people going to unheard of companies who offer "custom" tuning.

turns out the guy has just flashed some software hes downloaded off the internet and away he goes.

Yep. For something as serious as a remap I'll not even consider some unkown tuner. In Cambridge seems to be a lot of those fantastic tuners who started the activity overnight. I wiould avoid them like the plague.

That's good then, they should have no issue with sorting your problem out. If the car was running fine before the remap, and the only thing you have changed is the map, then I think you know the answer.

Quantum Tuning heard there "brand" batted around the web, basically some guy runs "Quantum Tuning" and sells files allover the world, the guys are simply flashing the files.

Get your money back and get to a decent VAG specialist.

Not a happy bunny,this is the reply I got from the guy that mapped the car.
Hi John

thanks for your message... I've had this before on a couple of vehicles and each time it's been a different cause and never the map. As recently as lasts Friday i was called out to a garage to provide an egr solution on a LR Disco 3 that had the exact same symptoms as the egr valve was playing up. And a fortnight before that there was another LR vehicle where the crank sensor was playing up... Then there was a seat leon approx 4 years ago where it was a fuel pump, and a Morgan 4/4 which had poor quality fuel...

I'm confident it's not the map but without a garage looking at the vehicle in detail it's difficult for me to say what the root cause could be... Can I ask, is there a particular RPM range where this is happening? Under what driving have you noticed this? Have you had a diagnostic check done to see if there are any fault codes coming up?

I'll put your feedback up on our tuning forum to see if there is anything obvious others might suggest.

regards
Aled

And this is the reply I have sent to him,am I being unreasonable?
Aled,the car was absolutely fine before the remap,no issues at all,I'd rather have the original map put back on the car and a full refund given,I don't see why I should have the expense of having to pay out for a diagnostic check,and then have to pay out again for any work that might entail from that,possibly running into the hundreds of pounds,not happy at all!!

Who said it was cheap?they have very positive reviews on trust pilot
And if you check their website they are a very big player in the remapping
Business,perhaps I have just been unlucky,maybe the remap has found
Out a weakness somewhere in the chain,not happy though!

The only reason to go for a remap instead a box is the fact that the map will be made exactly to your car, optimized. If it's failing, it's clearly a copy/paste, as we know every car/engine is different, reason why a map should be done for your car.
Someone using the same 1.8 TSI would be able to use map 3 +3, but mine the stability is map 3 +2 or 3 +1. Same engine, but again, every engine is different.
Using a box like the one I'm using, from DTUK, you may not get the full potential, but the many maps/options, will make one suitable to your engine, but again, a good remap would give better results.
If you're using good fuel, a panel filter allowing good airflow, I don't see why the car is not 100% smooth 24/7. Those two factors would allow the remap to work without problems.

Problem is this guy isn't the company, hes just an agent. what he has flashed on your car is just a flash and go job.

Them reviews are generally written by people who have no idea at all and just believe everything the guy tells them.

"billybob remmaped my Vectra, it feels a lot faster now, he really knows his stuff"

What the hell is a flash and go job?he was a certified IMI technician who was sent
Across a quantum power map from head office,and then put that file on my car,no
Different to what any other tuner/mapper would do?

Exactly what you have described,He logged into a system. downloaded a file and flashed it to you car.

A decent tuner would offer to diagnose the issue.

Aled above works for himself/ a company who aren't quantum, he buys maps off them for xxx and adds xx% on top and resells them.

Hes a franchise basically, in 6 months time he might get a better offer from another tuning company and will start selling there's instead.

My advise would be to speak to Quantum HQ and tell them what has happend etc.

And your point is,why would that make it inferior to what any other mapper out there
Would do?what difference would it make if I bought the map of Aled,or directly from
Quantum,there identical aren't they?

My latest reply from Aled:
Hi John

If your vehicle were my own, I'd personally try putting the blend map back on and if that doesn't cure the driving issue then return the vehicle back to standard.

As mentioned in previous conversations, an engine map won't ever be the direct cause of a problem, not when you have a company like Quantum writing the file anyway... but the moment you increase power is the moment you increase the stress on all drive train components... so it could be that the natural rate of wear and tear just can't take a power map but might be perfectly happy with the blend map Quantum originally wrote for your vehicle.If the driveability issue still exists with the blend map on then i'd expect them to still exist with the original file on (and would personally suspect MAF sensor to be the issue - and look for a garage that had access to VAGCom) but as mentioned, will be happy to return the vehicle back to standard as per previous message.

The earliest I can get to you is Monday 10th of July. Can you please confirm if this is convenient for you.

regards
Aled

:blink::blink:


Surely this IMI Technician would have software and hardware to diagnose the issue with the car himself.

I would speak to Quantum HQ, advise them of the issue. They will probably advise you to come to HQ for testing/diagnostics, if they have a rolling road at HQ? or they will advise you to go to a local dealer than does have the equipment to look into it.

I'm guessing Aled is a mobile guy who turned up and flashed the file?

Think I'm going to get Aled to install it back to original spec in the hope
That the issues with hesitation are resolved,fed up with the whole saga
To be honest with you,get my investment back and move on.

that's why I was saying that even two cars are not identical. After the remap, as the engine will work harder, to achieve the optimum results, any weak link will show. The main vantage of someone really doing it, and knowing how to do and what's involved, is that in case some problem shows, he will be able to identify the cause, and adjust the map specifically to your car.
Just on a side note, as I drive the 1.8 TSI DSG. For some reason VW/Seat decided for the 7-speed dry clutch, maximum torque 250. If someone try to remap it and ignore the transmission limitations, will damage it. If it was a manual, simply opting for uprated clutch would allow quite some increase in torque. Knowing the limitations, DTUK with their box manage to increase power without going mad with torque, which was increased, but not to the point to cause problems. Same approach should be taken by the person doing the remap.
Another thing to take into consideration is, fuel quality, oil change intervals/quality, and overall status of the engine/components. For fact, using my tuning box, as other using their remaps, premium fuel and shorter oil change intervals are rule. Something like spend 100 to save thousands.

Off topic but why would anyone want to remap a 1.6 ecomotive? The power gains would be significant and if you're really after extra oomph, go for a Fr or cupra.
Sorry if this sounds condescending but it really baffles me when people remap cars that are tailored towards economy and not performance.
