who stole my remap ? maybe found the fault at last

[Mylo]

as DPJ and a couple of others know, I had a bit of trouble last summer with my remapped LC.

The leon spent a week with SEAT trying to find the source of my boost problems. Various tests and tweaks were done and in the end a sticking actuator led to the turbo being replaced. After that the car ran really well and appears to boost normally.

The car has since had the following bits fitted. Green filter, 007 and a THS t.i.p.

Today while waiting to get my Milltek fitted I used the free time to get it dyno'd and the results were not good

The guys ran VAGCOM and found nothing wrong so they copied the map off the ecu and got their software tech to look at it.
Apparently some of the blocks are incomplete (corrupt??) or haven't been changed and this is why the power is so low and the graph shows flat spots ??

I won't even try and pretend I know what this means, hence me posting

Is it possible that SEAT overwrote the ECU ?

 

[LEE69]

Sounds like it to me, maybe the over wrote it to put s fresh map on to rule it out?

Exhaust ok though?

 

[Mylo]

the tech that fitted it was almost as impressed as I was with it.

Brilliant build quality and it was easy to fit. Looks almost factory but sounds very nice

 

[LEE69]

Me jealous nahhhhhhhhhhhhhh



git!!!!

doesn't look like OEM torque - that's normally pretty level

Your Power flatlines, which suggests MAF or airflow restriction

What's the requested & delivered boost like?

 

[Mylo]

No idea mate, looks like I need some help to do some logging then Mark ?

Could an airflow restriction be the piping to the airbox not being good enough ?

 

[m0rk]

If you're using a 1.4 airbox maybe....

You need to log it.

But I'd be looking for stuff like an intercooler half full of oil if your boost is 'right' but the airflow is down

 

[Mylo]

I'll pop the bottom hose off and have a look

back soon !

 

[Mylo]

tiny bit of oil, consistent with the amount in the air pump on the t.i.p

 

[Damoegan]

What map was on it? Have you contacted the people who mapped it to see if they will flash it FOC?

 

[Mylo]

p-torque, not emailed Will yet

 

[Damoegan]

I'm more than sure Will will flash your map back on FOC mate

 

[Mylo]

no induction problems that I could spot, even swapped out the N75, 100mm air feed now fitted just for safety really need to get vag-com at home.

Have emailed Will

edit: road trip to p-t on wednesday

 

[Mylo]

well I had a nice trip up to P-Torque and all seems well with the map.

The car tried to bite Will as it was seriously in need of tracking, now sorted, and wanted to leave the RR
4th gear run gave it a chance to stretch its legs, paramount used 3rd ?
Still need to try cleaning the MAF.

The Milltek has started to sound really nice now it has a few hundred miles on it. Damn back box is too big to be really loud though

Discovered a split breather hose under the inlet manifold today after inspiration from another recent thread

Could a burst manifold breather be the cause of my cars flat line ?

I hope so

 

[Avant4me]

According to the graph, power is 203 bhp which is not too far off. Torque does seem to be down though. Car is obviously boosting properly now, would recomend you get some vag-com logging done.

I put my money on it ... make sure you reset ECU so it can relearn after... I had same issues that you've experienced and it was all down to that poxy pipe under the inlet manifold...

My remap is back on the car now and god does it shift
