hey guys i was just wondering why people need new ecus i know that other ecus can be better mapped. im getting my car mapped on thursday and just wondering do i need a new ecu? modds are listed below.

Um, I can't see any form of mappable ECU in your sig ?

Who is mapping your car - how are they doing it?

Common method is using a unichip which adapts the signals from the standard ECU.

For a stand alone 'mappable' ecu your looking at a couple of grand.

damn this confuses me redline racing are doing the mapp for me maybe im gettin a little too confused here im gettin a head ache. lol they are putting a chip on the car then mapping off that is that right? would that work. he has done many fiat coupes befor as well.

one of these?

i honestly have no clue havent been there yet going on thursday i will find out more info then. hmmm gettin a little worried now i dont think it is a piggyback ecu

how do pts mapp most peoples cars?

using a unichip as above.

It's called live mapping. They put a chip in the ECU, then use a emulator which will read everything real time. They then makes the changes on the emulator to suit your mods, once done, they burn the chip and this is now your new chip.

Plus side to this is there isn't the expense of the unichip and it's done all via the ECU instead of the unichip fighting / manulipuating the ECU

Only downside is if you need a re-map, you need to go back, and go through the whole process again, but it should be cheapier than the inital out lay of the unichip

hehe that makes sense cheer begbie! thank god for thank was getting a little worried there

I had this method done when i first got my coupe cost me £180 for 3hours mapping. Where is the place that is doing this?

saint alband i think use to be call ggb augusto is the man who does the mapping

thats a millenium chip by red dot.

is it any good do u know?

Begbie,

I didn't realise 20VT owners have this option!
BTW, when you say they replace the chip surely this new mappable chip will have base maps for the 20VT and then their s/w can modify them?

Not quite the same with us 16VT, tunerpro ostreich (sp?) and a wideband lambda (and as you mention a good ear for knocking...)

cheers

This sounds like what i'll be after if my mixture isn't running well. I don't intend to take any further power mods after FMIC and SI so i'd rather fork out £200 rather than £400-£500 if i can. Do all the usual rolling roads offer this?

I probably know of one company who could live map, but they are in blackpool and have a serious investment in there equipment, like 30k worth of equipment. There website is www.remapping.co.uk and if you want to have a proper read on what is involved with live mapping, sit back, get a brew on and read this

This is exactly what was done to my ECU. Doing this is better than a unichip as you have access to everything providing you have the correct software. I can get as far as chapter 4 but the problem is I don't have the software to interoperate the eeprom dump into a usable map also the emulator is key as you need it whilst live mapping. This method is just as good as going standalone except for our crappy airflow meter. I would recommend this method over unichip or any other piggy back chip. It may also be a better method than some standalones.
