Is the rs tuner map causing this?

[MichaelHirst]

Took the car down the local garage to get checked due to it struggling to rev in low rpm but it's fine when on full throttle, they simply said it's over fuelling and take the map off and get it done professionally! But reading the reviews on the map no one seems to suffer with this! Thinking it could be something else? Can't take the map off ATM due lost the original ecu setup also the engine coolant light is on! Any help or advice would be helpful thanks

I've had no problems with my RS tuner 98 Ron map, and like you said I don't know of anyone else how has.

Probably a fucked lambda sensor or something.

 

[bozothenutter]

Probably a f**ked lambda sensor or something.

this...only when cold?

 

[Addicted]

Oh, and are you using 98Ron as you should be?

Thought they ran open loop when cold??

no idea mate, but when mine went it ran poorly when cold and drank like a templar.....sounds like the OP if when cold

It's worse when cold I agree but comes and goes

He means are you using 98Ron fuel

dony know if this is any help ive had the awful cold running for 5 min problem used a bottle of cataclean and big improvement,not cured but from cold less noticeable and only lasts a min the most then car runs fine

Ahh my bad! Yes I've only even used tescos momentum anyway

 

[welshname]

Yeah I use that with no problems.

I'd suggest it's something else causing the overfuelling.

Is this the same as redex? If so used one a few months ago!

I had a similar problem and it turned out to be a loose spark plug, and shortly after the ht lead on the same cylinder died.

in a different league i think asked my local garage they use it its well used in the trade i think it sorted my pre cat lambda as car is running much better also 2mpg more im getting

Will take it back to the garage and tell them to take a look! Nice one

I wouldn't take it back to the garage. Sounds like they have no idea after the comments about the map. Changing a lambda is a very easy job to do yourself. In the mean time you can unplug your lambda and the ECU will use preset settings instead of the potentially very wrong ones it is currently using.

Absolutely useless with cars not going to lie, I'll have a look for a guide on YouTube.

^That.

 

[MichaelHirst]

Would it be the pre or the after one most probably? Or do both need doing! Thanks

 

[ADS_V6]

pre cat m8 do that 1 causes the most problems gsf do them and you get 10 percent off

Are the pre and post the same or different?

 

[bozothenutter]

Same sensor, diffrent wire length

 

[MichaelHirst]

Same sensor, diffrent wire length

Is the pre the longer or shorter? Cheers for help btw
