I have just bought a mk4 golf gti 1.8t with the AUM engine, year 2000, and one of the previous owners had it remapped (though i dont know what to) and i have found it hesitating at 3000 - 4000 revs, sounds similar to what was up with yours.
Do you think its worth a visit to carbon chiptuning? what are their prices like?
Cheers,
Gabriel

If there's a problem with the map Craig & the guys will find and sort it :wink:

Hope this is in the correct section
My Mapping Story/ Review Golf 1.8T AUM 150 - Carbon Chiptuning
Basically I had a map done by Jason at MORE-BHP about 3 weeks ago the map was ok there was a power increase but something seemed to be missing I had a hesitation at around 3200rpm which I posted in the ECU tuning section.
I received a PM from the The Doc from Carbon Chiptuning advising me of what they do and there service's, so I booked in for a consultation and pre Dyno.
I met Craig & Nick (:cool: TOP GUY'S :cool:) yesterday at there workshop in Altringham I have to say they have a very very nice & professional set up indeed :cool: they got to work to do the pre Dyno in no time at all, Both Nick & Craig set to work on my car going through everything with a fine tooth comb making sure everything was in order before they set to work on her, got to say Nick and Craig clearly knew what they where doing and they are the VAG GOD'S :cool:

IF being the operative word AS WE DIDN'T SAY THERE WAS A PROBLEM WITH THE MAP - we just said we'd like STU to take the PEPSI challenge with our map and a new N75 valve :wink:
AND we'll take the PEPSI challenge with anyone who feels the map they have is anything other than 100% perfection :wink:

I think that my standard map isn't 100% perfect.....what you gonna do about it? :huh
I'll give you a pepsi challenge.
My PD130 love wagon feels a bit flat. I think the "map" on it is a bit pony to be honest. Whatchya gonna do now.....
:grin:

You busy on Sat 25th of this month Craig?
0.7λ - I love the smell of petrol in the morning :laugh:
Nice output though, torque is a good level as well. :cool:

MAF ok and PCV sealed??? :undecided: Just strange how early the lambda steps down??
In the stock mapping and AUM is mapped to 0.7031λ at 150% load @ 6520rpm via a fuel dump to hardware protection (Lambdasoll für Bauteileschutz). By how the lambda is stepping down I would say the protection fuel map is running due the running temps v load% and rpm which produces a equasion to the EGTs . Off hardware protection the fuel will be around .95λ. On a AUM running a stock exhaust system its good practice to leave the protection maps in place to give a bit of cylinder cooling under high loads. Driving on the road at speed with good air flow into the intercooler you will be running around a around .84λ. Only when a downpipe and sports car fitted its safe to run a fuel ratio of performance and not protection.
I wouldn't say that the early step down is anything to worry about, if anything, yes there will be a slight fuel penalty, but more power = more fuel. You'll get a slight benefit in terms of lowering in-cylinder temperatures and EGTs so the effects should balance roughly. (from my OEM experience) However, I am not a software monkey so couldn't comment on the more indepth goings on.
I was more laughing at the lambda as a similar level in diesels makes them right smokey bastids... oh and I love the smell of petrol. :lipsrsealed:

Sorry mate, have been mega busy these last few days! I'll hit you up with a PM this evening :wink:

Hi
My reply was to do with software and aim towards it should not dip like take at that point, the aum sw has maps for cylinder wall wetting for cooling at the top end of the rpm range, but in the peak torque band it should be around 13.5:1. I cannot see why the fuel steps early, unless the maf is reading wrong or a PVC leak as this is the only time I see plots like this. The other problem will be too much fuel at lower cat temp washing the cat out. Fingers crossed tomorrow his graph will be better. Bosch make the ecu too complex for it's own good. Lol
Them plates are going to get you in trouble :laugh:
So was the 40NM over the dyno plots on the previous page? I.E. you are now around 190NM? If so, that's tasty. What are the standard clutches good for?

Yup, like this N75 :grin:
Sweet - when you coming back :cool:

just sent nick a text now, possibly monday 11th july or possibly TBC 7th July? as doing the N249 bypass at the weekend :cool:

your not f11cking around are you :wink:
Can't wait to see where we end up with this for the modest outlay :wink:
I'm on holiday next Thursday :sad:
