Re-Mapping, your experiences.

Thinking of getting my 2.0T A4 rempped, but my only reservation is the fact that it's a FWD

Not likely to cause you problems tbh.

My E36 328i has been remapped, it now has 208bhp / 221LB/ft
I didn't bother with the 325i manifold, I've seen dyno graphs of those and you lose torque all the way through the midrange just for the top end power gain. Mine is just strong all the way.
I'd certainly recommend it, the motor is more responsive and the delivery seems smoother than before.

Is there any way of tracing that the car's been remapped?

I'm guessing its the same engine as in my Octavia if so it is worth it. It makes a dramatic difference in throttle response and the power delivery is immense. Totaly transforms the car.

But would remapping it with the M50 manifold not compensate for the loss in torque?

I ask as I am thinking about getting my E46 328i mapped and I was going to put the 325i manifold on first.

Glad the remap made a difference though

As I understand it you need to get it checked by a tuner with a suitable laptop program or dyno. It can't be detected just by looking at it

I would think any remap worth paying for would need to be done on a dyno, where the AFR can be recorded and the fueling adjusted accordingly? Strikes me as stabbing in the dark otherwise.

Only exception would be where the manufacturer has put different ECU maps on the same engine to differentiate models by reducing power on the lesser spec model.

The guy doing it on your drive probably just messed with the throttle response.

+1

The benefits are massive on that engine, dont hesitate to get it done.

Not a lot of money for a substantial gain, I imagine. I don't know if it's worth getting my 528 done.

There's no substantial gain in remapping a NA petrol 1.6.

He would have to fit hotter cams for that to be worthwhile. It'd be simper/cheaper to just buy a more powerful focus.

I really want it done on my Fabia, but not sure it would be a good idea. The engine in standard form has poor reputation for reliability...

Seat Leon Cupra, went from 240bhp to 300bhp. Made a big difference to the way the car drove, though the huge increase in torque from 2000rpm onwards caused the clutch to slip.

Now that most (all?) cars have DBW throttles, it's very easy to make the car 'feel' faster, as all they have to do is alter the software to make the throttle more sensitive to smaller movements of the pedal. Not sure it's worth paying £200 for.

Definitely, in order to get the best for that particular engine. 'Standard' aftermarket maps are probably a baseline configured on a different car of the same model to give a close, but not optimal, map. That's certainly how it worked on bikes with Power Commanders anyway.

Putting the Zed in for a remap and a blat on the dyno in a couple of weeks - hopefully gonna be nudging 300 with the new intake and exhaust bits on her. More than that I want rid of the 155 limiter (just because I can ) and to do away with the power limiting in low gears.

Will post results when it gets done.

My Nissan 180SX (SR20DET engine) has a standard drop-in chip from Horsham Developments. Very good response, and fuel economy. Not really any reason *not* to remap on these older turbo cars - they seem to run unnecessarily rich as standard, which is just pouring money down the drain.

[The_Burg]

First commute with the new map, really feels much livelier low down the rev range, where it sits most the time. Top end feels no different, the annoying glitch just off idle has vanished making it far nicer and no need to rev it off the line.

Trip computer reported 40.1mpg, usually see around 34mpg. Quite a difference.

Very happy so far. Why all the fuss about £200? A noisy backbox costs far more and does nothing at all?

It's no sports car and never will be which isn't it's role anyway, but is far nicer.

[Motorrad]

I've either chipped/remapped every turbo car I've ever owned.

The results were always well worth the money.

The four that really stand out are

RS2- not just the BHP increase but masses more torque throughout the rev range.

Impreza Turbo 2000-with the larger TD05 turbo and on the aggressive side the 'scoobyecu' which cost me 50 quid turned the car from nippy to ballistic and reduced lag.

Golf MKIV TDi 150- I used REVO for the remap- it was generic but supposed to produce 190bhp and more torque. It improved the poor driving characteristics of the diesel engine by widening the power band. Still a st car overall but passable with the remap.

Golf MKV GTi- like a flaccid stick of celery before the REVO map. Much improved with what felt like a hell of a lot more power and torque throughout. Not cheap at 500 quid and whatever they were asking for the switch that allowed you to control how aggressive the map was. Or amusingly set it into 'valet' mode so that the usual tts you get at garages can't take it for a joyride.

The M50 manifold does not fit on the E46 328. You can fit an M54 manifold from a 330i from what I have read though.

I have had all my recent cars mapped,

Audi A4 2.0 diesel - Good improvement, much stronger mid range although eats front tires.
BMW 530Msport diesel - Car was fantastic after remap, great torque and mid range. Wish i had never sold it.
BMW X5 diesel 3.0 - Same engine as above, great results.
Porsche 996 turbo - WOW.

Monaro was rempapped under my ownership, totally transformed the car.

Better throttle response and about a 20-30rwhp gain, on a N/A engine.

Bought the alfa GT already remapped, Put it back to standard soon after.

It was no doubt quicker but power was not linear, clutch was slipping when it came on boost in high gears.

It always felt like it wanted to go, the power was just so on/off. BOOOM change gear/ repeat.

Trip computer was also well out.

Stock map was much better, with no clutch slip.
