Remapped Diesel Soot Experiences

[m4rtin]

Hi All,

My Ibiza FR 130 PD was remapped and I experienced problems with the huge amount of diesel soot deposits left all over the back of the bumper, boot, etc, and with my Ibiza being yellow this wasn't a good luck (I had to clean it nearly everyday). I've had the map changed but now it seems that I've lost 90% of the extra power it (after the first remap).

For all of you that have had your 130 PD engines remapped have you experienced similar problems (with exessive diesel soot deposits) or is this not normally an issue. If you could also let me know where you've had yours done too that we be really helpful - If it's just an issue with the map I had I might be tempted to try somewhere else

Many thanks for your help.

Martin, does your car have the 'hidden' tailpipes under the bumper or do they stick out a bit?

 

[m4rtin]

I'm afraid the FR has the twin chrome tailpipe which sticks out past the exhaust, I suppose this doesn't help either but I don't really want to change it

 

[UncleFester]

No, sticking out pipes are better than the stealth ones, it encourages the soot to move away from the car.

Do you drive it through the rev range a lot, or do you just boot it now and then?

 

[m4rtin]

Where possible I'm normally giving it some stick, but on the way to work and back (in traffic) I just take it easy and benefit from good MPGs

 

[UncleFester]

I wonder if it just needs a good clear out, although if you talk to MikeyH on here, he was saying his deposits a fair bit of soot too - might just be because the car is yellow it stands out more?

But that is the main problem here... You'll only get rid of the soot by having the tailpipes pointing down or reducing the remap power or by installing a bigger turbo (ex:VNT1749VB from PD150's) so that boost can increase a bit and help clean out the soot output. This last option would also bring along a nice power/torque increase...

BTW, does anyone recommend any diesel additives so that it might help out to reduce the soot a bit?
I've made a few experiments, but none worth bothering I'm affraid...

My opinon is that it didn't seem right, the build up was reasobable bad even after a 32 mile round trip to work. I clean my car everyweek and even one of my friend's Mum said how dirty it was and didn't believe me when I said I washed it 3 days earlier.

 

[UncleFester]

In that case ... i don't know, mine doesn't smoke or drop that much soot even though it is remapped and has been for a while. That said. my car has no idea what a gentle drive is

i dont get any soot, possibly a bit upon full chat at low rpm, but nothing you can see without the sunlight being out in your rear view mirror, even when headlights azre behind theres hardly enything. Car stays clean for weeks.

Remapped PD130. Exhausts point down too

Depends which map you have, the more they fuel it, the more they smoke.

 

[m4rtin]

Which remap do you have jsparks?

 

[jsparks]

I have a skn tuning one mate, apparently makes 170 bhp ish but feels superb had a run with a jabba pd150 golf and there wasn't much in it .

 

[devonutopia]

Mine's pretty clean now, apart from if you drive it like a fool and try flooring it off-boost. My exhaust sticks straight out the back and I actually never have to clean the back apart from the usual road grime, never soot. I see a bit of smoke at night in other car's headlights when on boost, but generally mine's pretty clean.

Allard mapping with a lot of their tuning gear fitted.

yeah does sound like the map you have is overfuelling too much, much like the old resistor tuning boxes. what remap is it?

 

[m4rtin]

It a local place not to far from me, not mainstream like Revo, Jabba or APR, that's why I'm considering a Revo instead but don't want the same problem again

 

[sssstew]

yes, i fear they have just upped the injection quantity which does increase power but its not the best way and produces soot like you have found if its set to high.

i would recommend anybody really, ptorque, skn, jabba, revo, ive heard some revo maps are harsh on the clutch though. Sounds to me like they have done the tuning box mod

More fuel less boost, where as a propper remap is a bit of both. I get better mpg with the remap!

 

[UncleFester]

Don't be sold on the idea that some maps are more clutch friendly either, if you drive your car like a hooligan, it's the user that kills the clutch not the map or tuner. You're simply prolonging the inevitable. If i had my choice again, i'd have had a FULL uprated clutch fitted with the remap.

I was quite pleased with Millers 4, didnt see any benefits apart from less smoke, will buy a bottle every quarter or so just to keep the pipes lubricated.
