Re map question

[dan wiltshire]

How do I know if I have a crap map I brought the car already re mapped and it smokes when I put my foot down 80% of the time.
The cars also quick somtimes and others not any ideas or responses id really appreciate :-) (the map was done by "bentley uk")

[Poodle]

Sounds like a shit map lol. Only way to be sure is to get it dyno'd or have someone look at the map for you.

[dan wiltshire]

Any cheaper ways lol?? I dont wana pay loads for a dyno and no one local can do maps

[Strikeforce]

There is 3 mappers on here which all do them cheap
Worth giving them a pm to get a propper map or having a look at yours

[dan wiltshire]

Sorry all the questions do you know which one is closest to me (trowbridge wiltshire)

Pro_steve is not too far from you, he's based in Bristol.

Could the MAF be playing up causing the smoke?

You could try unplugging the MAF to see if that improve things? (only unplug it with the ignition off)

If it does improve replace the MAF with a Siemens VDO one and not a cheap ebay special as they only go wrong quickly.

Just buy the tool and map it yourself.. I'm sure even if you don't have a laptop you can find someone that does.

Symptoms sound like the maf

[Piggy]

yeah sounds like a fault rather than a map

[dan wiltshire]

Wheres the plug for maf sensor?

[DeeTurbo]

You'll see a plug grey behind the air filter that's it.

[dan wiltshire]

Ok il try that thankyou. Will this have been affecting the perfomance if it is nackerd?

[DeeTurbo]

Yeah when the MAF plays up the car goes sluggish. Let us know how you get on.

[dan wiltshire]

Just done it and my car goes like a slug with it unplugged really slows it down and engine management light comes on?

[DeeTurbo]

That's strange, usually it will go better or they'd be no noticeable difference. Does the light go out once plugged back in? What plate is you car on and do you know if its the three plug ECU or one?

[dan wiltshire]

I have a k and n cone filter (cheap crap one) if that makes a differance? When I unplugged it the engine managment light came on I plugged it back in and it was still on then I turnt the engine on and off again then the light went out. Its a 1999 hdi medran not sure on the ecu really.

---

When I unpluged it the engine was off and keys not in ignition

[Arron]

Is it a t or v reg? Some are known to do that, like mine! Mines on a v reg, poodles also does it

Any chance you can try a fellow members maf who's close by?

[dan wiltshire]

T reg . Dont know anyone around that has one :-(

[DeeTurbo]

The oil for those filters kill MAF's. It's been proven that the standard air filter and box are better on warmer days, anyway as you don't know anyone you can borrow one off I would say talk to Steve, drop him an email. His away at the moment but his got all the skills you need to sort out your problems. Remap@hdi-tuning.co.uk

[Arron]

Either get one from a scrappy or eBay. But as said Steve is Mega helpful at diag for these and all the mappers do a brill job if your thinking of another map

[dan wiltshire]

Spot on thanks guys appreciate the help

[Poodle]

If youre going to get another id recommend genuine and new myself, you dont know how long a second hamd one will last and ebay jobbies are generally poor quality. Steve has pp2k so hell be able to tell you if its knackered or not.

Steve is a legend! I had a problem with my maf, if you unplug it on a standard map, it makes it better. But if you unplug it on a custom map, it makes it much much worse.
