Leon Cupra 1.8 20VT Boost?

[davis_luke]

Hi guys, recently bought my self a Leon Cupra 1.8 20VT - What should be the standard boost pressure in bar? I get 0.8bar briefly and 0.6bar held through the revs. Ive just had a 210bhp - 225bhp remap and the boost doesn't seem to have altered - any ideas on what I should be boosting at around 210bhp?

Thanks.

that is majorly wrong, it should be 1.3/1.4 bar for stage 1.

Nope, 0.8 bar is around +-215Bhp. I have 1.3 bar with my 261bhp. Standard should be 0.6 bar.

19 psi max (1.3 bar) is 210 on a stock auq, well mine at the time

Peaks at 1.3 drops to about .85

Unfortunately I dont have the same graph with boost figures. I have an AUQ with k03s.

. I have an AUQ with k03s.

Me too, this was stage 1 on a totally stock set up. Things have changed now

So had it back in today and they loaded another map on to my ECU, reaching the desired 1.2bar over boost and holding 1bar. But it had a misfire and was farting about, he had to re-load my standard map and give me my money back..... Any ideas? Runs spot on hitting 0.8 and hold 0.6? Confused.com?

That sounds like stage 1 to me. Measure max MAF value with Torque or Vagcom and divide max g/s by 0.8. Then you'll have an idea how much power you have.

the misfire could be coilpacks, depending on year fone your seat dealer as there was a recall on them

 

[davis_luke]

Ok so back on standard map and its now started misfiring under load. Orange engine light flashes for a few seconds then goes off. Any ideas? It's looking like the re-map uncovered a problem that was ready for showing its face.....

You need to log /scan with vagcom to get to know more. We're only guessing at this point...

 

[Bouncerbeater]

Possibly coilpacks but as said above, a scan will give a better idea. There's nothing more costly than throwing parts at a car when you don't know what's wrong.

What bouncerbeater says. I also think coilpacks, but better be sure by scanning.

FYI: the coilpack recall has been stopped in the Netherlands, I believe it stopped earlier this year.

 

[davis_luke]

Thanks guys, bought a Bosch coil pack for cylinder no. 1 as it looked old and wasn't a Bosch one. Not misfire free. Plugged it in to diag and hey presto code stored for misfire in no. 1. Good guess I suppose. Loading the map back on tomorrow's so will let you know how it goes.

hey sorry to bring back up I bought a leon cupra not long ago it has air filter with heat shiled 4 bar FRP forge 007p DV green spring and remapped it peaks at 1.4 bar the guy who had it before claims its 210-220 hp no proof but its defo been mapped I need to get it on a dyno

Remapped? Change spring to yellow. Green spring holds about 1 bar if I am not mistaken. Dyno is a good/great idea!
