Random request – Polo 6n

[Chris S]

Oh my god, I love it, it actually made me laugh out loud! “a bit like driving a bouncy castle” I am still laffing at
the thought of it 5 minutes later, what a brilliant description, all I have to do now is to translate it into Dutch.

Dutch translation for Bouncy Castle :

Hobbelend Kasteel

Those engines will appreciate ‘breathing-updates’ and a
chip accompanying the breathingmods….

So is a chip replacement the only way to adjust the fuelling? Is it an eprom based system?

Just re-reading this and had a thought assuming things havn’t changed…if your (wife’s) polo has a Lambda sensor, disconnect it and take it for a run.
With the Lambda disconnected the ECU will still run the engine but in a safer mode which should mean running it rich….!!!
the downside is it might back off the ignition advance as well losing performance!! worth a try maybe?

other than that get it checked by VAG or with a reader, the Lambda might well be knackered, telling lies and making the mixture weaker than it should be.

good suggestion mike, although t’s actually had a recent lambda so i think it’s running as the factory intended, just that’s kinda weedy. I’d like to be able to run it a bit rich to cover the flat spots. It’s better since fiddlign with the timiing but there are still definite bits where it “falters” and I reckon more fuel would solve that.

I guess they tuned for economy rather than performance. It’s quite a nippy little go-kart for round town esp with the stiffer springs, I’m just missing the “mixture adjustment” screw.

I reckon my best plan is going to be piggybacking whatever sensor decides how much air is coming in like the little add-on resistor jobbies. Once I’ve cleaned up and sold the gti I’ll be working on this car in a bit more depth so will test in more detail then

any blows in the exhaust before the lambda sensor no matter how small will piss the ecu right off

[ld50]

ah good to know danny, cheers. I will check for that too

translation for bouncy castle, springkasteel ;p

nd my neighbour has one in his yard, 1.4 8v, i’ll ask him if i could test some things and let you know

[ld50]

great thanks
