Hi all,

Ok looking to get mine remapped to get more BHP and better MPG

question is will it help?

MPG increase yes or no?
BHP increase yes or no?

if yes then what is cheapest and best way to go about it?

Do i get a spare ECU so i have original as backup or put back to normal and spare as remapped one?

cost to remap in staffordshire area?

thanks in advance

you can get kit's to do all that with out having to do a thing to the ECU.

[Shark1e]

any ideas what they are called or where to find them?

This Diesel?

If so contact TheBoy or Omegatoy who can put you in touch with a chip supplier.

You need to know your ECU type, and you may need to unsolder the existing chip, and solder in a socket.

The TD's were massively detuned by BMW, this chip puts the performance back where it should be 

Highly recommended by everyone who has done it, I beleive the only downside is the MID is no longer accurate, but you get lots better power AND economy

motorfactors have them, there are to meny names to remember but all under £70.

yes mate the bmw lump, previous owner my mate said he had it tuned and was too mad for him and smoked when accelerating lot so had it put back, but i think it feels flatter than a witches t*t if you get my drift.

sure he said chip had to come out copied and reprogrammed, so wonder if already has the socket job done?

[Jimbob]

open up the ecu and check, you will need the type (427 or 428 from memory) in order to get the right chip.

ok thanks,

what is the procedure for opening the ecu? battery dissconnect? or just unplug ecu?

do i just send off for a new chip or will mine have to be reprogrammed? does mine hold codes for things like remotes keys etc

i have pm'd theboy

[Jimbob]

just unplug it and open it up

(anti static precautions should be used)

you get a whole new chip to plug in.

remotes etc not affected.

all easy (unless your existing chip is soldered in, in which case unsolder, and solder in chip holder...old and new chips can then be swapped at will.  If this is beyond your skills, tv repair shops etc will likely do the soldering work for a small fee  )

can solder no probs, just had a call back from a local ecu mapper and he quoted £200 and has to have car to read ecu and order chip from ireland, can have car back and go back in couple of days to have chip put in,

must be cheaper else where than £200 or is that the normal?

TheBoy can source it for a LOT less!

cheers i await his reply lol

Not properly. Plug in resistors, etc. that attempt to fool the ECU are a waste of time. There is a very worthwhile and reasonably priced chip change for the 2.5td that many members have used. Not worth trying anything else.

Just beware that, if it's an auto, you'll need to change the gearbox for the stronger AR25 or it'll fail very quickly.

EDIT: Just noticed it's a manual so go for it.

no not them  it plugs into ecu and the one on car fits into it 2" space needed, seen them on sport shop in motor shop. so have 2 ratings and some go up to 10 ratings.

just spotted we have a how2...
