Ecu Remap Ebay

[A4 TURBO]

ive found a company on ebay that sells you a NEW chip that has already bin remapped. it comes from austria and it only £100.00 they have good feed back and all you do is give them your ecu code off the top and they send you a new chip remapped for your car??? for my 1.8 turbo A4 expected bhp 190bhp. im happy to install chip my self but what do you all think??

[docurley]

Its one of thouse very grey area and I would not do it.

[ini]

It is no different than any generic remap.

It may be good, it may not, the only thing to ensure is that someone competent does any soldering, if needed.

I am also trying some mail order 'chips', 2 sets from Germany, £35 each.

[docurley]

Let us all know how you get on.

[A4 TURBO]

god i dont know what to do!!!!!!!!! it so much cheaper and in theroy there no reason why it shouldnt work but my with my luck it prob wont work!!!!!!!!!!!!

[ini]

One of the sets of chips is from a guy who only tunes cars with my exact engine code, so hopefully he knows what he is doing.

The chips are so cheap, that if they are no good i can bin them and re-socket my original chips.

could you get me one?? if so how much???

[ini]

This is an ebay item from one of the German guys i tried.

Ebay item: 270154570194

You will have to copy and paste the web address into babelfish to translate from German.

He sells remapped mail order chips for all VW/AUDI TDI Bosch ECU's, both VE & PD.

To view the other items he sells you will have to go to www.ebay.de (http://www.ebay.de), as they are not visible from UK ebay.

[A4 TURBO]

well its on its way. ive ordered one of him about £45.00 in total with p+p with estimated bhp increase of about 40bhp. i will let you know how i get on or if it blows my car up

[A4 TURBO]

chip is here....fingers crossed fitting soon i will let you know how goes

Hi ini,
I think you have the AFN engine (same as mine) - so I would be very interested to hear the results. How easy is chip swapping - is any soldering required or are they just plug-in?

[30boz]

A4 turbo Howd you get on. Im waiting with baited breath!

I love my a4 18t but it could really with some more poke

Cheers

It depends what year your 'AFN' is.

If you have the early type ECU (it has a MAP pressure tube going to it) you have to solder in 2 surface mount plcc32 socketts and install remaped or flashable chips. (ECU is non-flashable by OBD or direct serial)

If you have the later type ECU (generally facelift-ish with 2x ECU connectors & MAP at intercooler) your ECU should be flashable through the OBD port, or serial flash chips directly)

[A4 TURBO]

about to fit now yes lots of soldering to do a mm wide!!!!!!!!! 44 of them ill let you know wish me luck

[A4 TURBO]

no not fitiing it. do not buy unless you are a good soldering person and have all the good special tools!!!!!!! high risk of damage to board

My AFN is 97YM. I can't see any pressure tube going into ECU, neither can I see MAP at intercooler, but its hard to see much in this area. I suspect I've got the later type, in which case an upgrade can only be done by flashing and not chip replacement. Is this correct?

Question for A4 Turbo: what is your engine and MY? I wish you luck soldering 44 x 1mm contacts. Doesn't leave much room for error, does it? Did you have to de-solder first; sounds like an even bigger nightmare! What happens if you want to go back to the original setup?

[A4 TURBO]

my engine is aeb and early type which has chips soldered on the later type are like a socket type where the chip pops out. and you can but a remapped chip and JUST slot in

[ini]

Every car (apart from some very new ones) can be 'chipped' by soldering/socketing new chips onto the ECU, this is the way all remapping used to happen.

Fitting 'socket/s' for the chips in your ECU is very worthwhile, as if you do not like your 'remap', you can just put the original chip/s back into your new socket, or swap chips or flash new maps (depending on chip type).

The later type ECU's have flashable chips, and can also use the less invasive OBD flashing, or serial write without any soldering.

For a 97 'AFN' engine, if you remove the black plastic cover for the ECU, and the metal ECU body looks like this (probably all silver on an AUDI, not black):

You 'most likely' have a board mounted MAP sensor with a tube going to it, and 2 'plcc32' chips like this (bit out of focus/dodgy phone macro):

http://i118.photobucket.com/albums/o99/inisj/plcc32.jpg

If so, simply use a good 'micro-electronic engineer' / microsoldering service to install the plcc32 sockets (mine cost £20):

If you want to solder in the sockets yourself, this link explains how. They do not really need 'Hot air' soldering, and can be done by a competent hobbyist, but it is too fine for my soldering 'ability'.

If you have the later type ECU body (with remote MAP sensor), like this:

You can use the less invasive non-soldering type remap, or if you wish install sockets (if none are present).

[AutoTDI]

Hi ini,
Thanks for taking the trouble to provide that very detailed explanation. I'm now much better informed as to what's involved and I can see how the original chips could be easily reinstated. I suppose the reasons for not having sockets in the first place would be lower manufacturing cost and better reliability. I now need to inspect my ECU in detail, to see exactly what I've got and then consider my next move.

[A4 TURBO]

need to find a eletronics guy to fit mine!!!!!!!!!

[andysuth]

OK, I've got my nerdy coat on, so here comes the nerdy question: What MPG did you get before/after the remap?

Currently I'm getting an average of just below 50mpg, 55mpg on long journeys and 45 on shorter journeys, but I'd love to get more out.

Has your remap helped? or are you just driving more aggressively now you've got the remap?

-AS

[AutoTDI]

According to my Haynes manual, if the ECU is disconnected and then re-connected, it must be re-initialised by an Audi dealer using special equipment. Is this correct? How can disconnection be any different to completely removing power; eg when replacing the battery?

[ini]

Your existing instruments/immob 2 & ECU match, so there is no problem.

For most B5 A4's it only really applies to fitting a different ECU.

You could always use vagcom to find your immob ID first.

[A4 TURBO]

the new ecu is fitted!!!!!!!!!!!!!!!!!!!!!!!!!!!! i found a guy who works with a laser cutting machine designed for removing chips and fitted new ones. and what a difference!!!!!!!!!!!! so in total it cost me £70.00 not bad saving over £200.00

[A4 TURBO]

need to upgrade to forge acuator and dump valve............. plus new intercooler near xmas and new exhaust manifold and then last but not least exhuast system has anyone got any of theses for sale lol

[30boz]

A4T

It worked then? Did you get off ebay.de? Is your car 1.8 t petrol the same as mine? Do you get better MPG too? Do I have anymore questions?...oh Yeh should I get one?

Cheers
Boz

[A4 TURBO]

yes it worked yes it came off ebay de. just email him your ecu number and done!!!!!! just get a proper person to solder it in and oh my god it bloody flys......it eats all chav cars alive and spits them out!!!!! hahahahaha

Are you going to give him a plug on the forum?

Tempted, but the only surface mount soldering person I know is refusing to touch my ECU for the fitting of a socket.

[jsmithee]

A4T, ini, i've looked all over ebay.de and cannot find this bloke who sells them chips, I have 1998 1.8T non FBW AEB same as yours so i will have to do the same as you have to chip it - how much did you pay the guy to remove the old chips and solder the sockets in? did you have to register at ebay.de to buy the chips? thanks.

[ini]

You dont have to register on german ebay, just 'watch' the item, and you can buy from UK ebay.

If you have non socketted 'surface mount' chips in your ECU, you really need to have them removed with a 'hot air' soldering tool (or similar), which will melt the solder on all the legs at once.

Taking the chips off the board is the most tricky part, as there is a high risk of pulling a track/trace out of the board if it is not done correctly. ( 'hot air' soldering will remove an IC in 5 seconds)

Once the chip has been removed, tin up the pads if needed, and ensure they are 'flat'.

The socket is easy to solder onto the board, but is very fine work, and a steady hand and fine tip is needed. Simply paint the 'pads' with flux, align the legs, and spot a couple onto the board to hold it in place.

When you have finished soldering, check each leg with a pin/needle to ensure it is solid.

Many mobile phone repair shops will have 'hot air' soldering tools or similar.

In the end i had my sockets fitted for free, at a local 'circuit board' manufacturers.

That easier said than done......i really wouldnt try doing your self unless obv you have the gear... your right though mobile phone repair, pcb makers etc. If you search on ebay and just search audi performance chip and it will come up......it is wrote in german though

[A4 TURBO]

and good news too had no difference in mpg!!!!!!!!! but a huge increase in woosh. what bhp increase have i had does any one know??? beacuse i aint making this up the car flys now(helped by decat pipe) it out runs some meaty engines out there!!!!!!!!!

[andysuth]

and good news too had no difference in mpg!!!!!!!!! but a huge increase in woosh.

Probably asking wrong guy, but any chance you could drive like a granddad and see if there's and increase in MPG?

;P

-AS

[A4 TURBO]

if im illl i might try to drive in 5th gear at 30mph for a while...lol. end of day the main point of chip is for increase in bhp really not mpg... like said though i had no difference yet in mpg

[jsmithee]

thanks ini, a4turbo - finally found it (sjk digital?), i was trying to do the whole lot from babelfish, but you have to find it first then translate, doh. The petrol chip is about £70.00 then - what i dont understand is it says increased performance of 15-45 PS, so which is it?

[A4 TURBO]

yes that it sjk!!! the reason why it shows 15-45ps is because the site just avertises a chip depending on what engine you got depends on increse ie= if you have a aeb 1.8L engine (non turbo) about a 15ps increase but for example if you have 1.8 turbo about 30-45ps increase

[30boz]

Just one thing about all this.

Wheres the ecu on 03 1.8t petrol avant? And where do you get the number from that you have to quote on the website so you know you're getting the right chip?

Help/advice much appreciated

Cheers
Boz

[jsmithee]

ive seen a4 turbo make later posts about this and it seems the map may be wrong, ive decided to save up and get it done at a proper remap place (anyone used DNA? they are fairly close to me) i know someone who could solder the chip in for me for a reasonable price, but until i know the chips are any good then i aint doing it.

to get the part no of the ecu you have to remove it (black box under wipers, drivers side)
