Instaling chip in 2.5d ecu

Hi,

I have been quoted £300 plus VAT fitted or £200 plus VAT unfitted for a remaped chip from Bel Auto Services at York.

I have spoken to them and I have also been in to the ECU and located the chip.

I'm not experienced at soldering but do have an iron and am generally good with most things I try.

Does anybody have any tips with regards to removing the old chip?

I'm a little concerned too much heat may damage the chip.

Any info would be great thanks.

this chip you are going to solder in! i presume its pre-set?? IE: you solder it in and its programmed to run to the engine it was designed for in the 1st place!
would it not be better to spend the extra few quid and have it live mapped to "your" engine! this way you will get the best in performance and economy and the best in running order! live mapping is the nuts if you spend a few quid

I think you have got confused somewhat.

The term chipping came around because the chips in earlier cars ECUs were unable to be reprogrammed with new data like modern cars can these days. Early <2001 Range Rovers are unable to be flashed/reprogrammed.

This meant that a new blank chip had to be reprogrammed with new data and then had to be installed back in the ECU. Hence chipping it.

Bell Autos are amongs the best in the UK at what they do and yes the new chip is programmed to be a safe but big improvement over standard for the engine in question.

I just want some tips on soldering really before I decide if I should attempt to do the job myself.

You are taking a big gamble. You need a special soldering iron, low voltage with no or minimum eddie currents generated at the tip as these can destroy the chip. You need to be earthed so that any build up of static is avoided, this will also destroy the chip. Excess heat will destroy the chip I can give you some more negatives if you wish. If you go ahead, I would recomend that a socket is installed into which the new chip can be fitted, if it is a type that will go in a socket (ie not surface mount)
Frankly I think you would be much better off just having the ECU re-mapped assuming it is a re-mappable device

P.S. Mine has a box that plugs into the loom which ups the power to 150bhp allegedly.

Hi, the new chip comes with a bracket, so that you just plug it in.

I will have a think and watch a few more clips on you tube. lol
