JBS Manifold Logs

[ibizacupra]

Been at bills all week, had new plugs, coils, maf, egt probe, injectors, new map running actuator pressure , wmi off. Unfortunately it still misfires.

EGT's are over 900 but on the oem manifold they were less than this (as can been seen on the logs from the first page).

Misfires coincide with fuel dump from egt's so at the moment its looks like its the manifold causing the misfires due to high egt's and fuel dump.

Actuator Pressure only run - boost creeps from 14psi to 22psi

Ive been there mate JBS managed to f**k my car up after a remap, cost me over a £1000 to get it put right. There a bunch of amateurs.

Really? Not jbs surely

 

[ibizacupra]

some verification here...

There is an egt probe issue as I have confirmed here just now..
I would not want to trust the sensor which also does this randomly...

clearly it does not leap from 765'c to 1100'c (max sensor output which also bring with it 40% additional fuel dump, which would put anyones spark out!)
Nor does it go from 795'c to -40'c and back again in under a second.

Let not be too hasty.. There are issues with this car currently. EGT probe to me is confirmed intermittent faulty, and I would not trust anything it says. Once its cooled down the new one is refitted and checked again on the dyno under same test conditions we will know.

[jonathanp]

good news (crosses fingers)

lets hope it makes a difference, be nice if egt's read below 900 but we'll see.

 

[sTTickman]

What happened?

What ever happened to this post? Just came across it as I've been waiting for the JBS mani also.

 

[J@mes]

forget about it mate, i know i did!

just checked their website out of curiosity and only the ko3 manifold is there still!!!

 

[jonathanp]

I think they are still waiting for replacements to come in. I rang them about 2 weeks ago to get a replacement as mine has hairline cracks in a few places

oh dear! good luck.

 

[ibizacupra]

Sandip has posted they're on their way on ASN 8L section forum

 

[sTTickman]

I hope he right. I've had their K05 turbo and ECU in my basement for well over a year waiting for this mani. Thanks for the update.

 

[sTTickman]

JBS K04 Manifold in!!

Well, they finally have it for sale. Head on over....

 

[J@mes]

thanks for the heads up!

coincidently awesome have announced TODAY they are selling one too (http://www.seatcupra.net/forums/showthread.php?t=346092) which looks very similar, but its £525 not £405!!!!

Strange coincedence eh

 

[ibizacupra]

Identical to JBS one..........

what on earth is occuring there then?

just grind off the fins and JBS logo its the same item

someones getting screwed over on manufacture/supply maybe?

how bizarre

 

[ibizacupra]

seems the JBS K03 one (missing the logo) is also on their website
