My insurance is due and the warrenty is about to run out so i thought id get quotes including a remap just to see how much they load it. When i said i was going to have it remapped they couldnt find the words remap on the computers and we had to settle for "engine chipped" or "engine management tuned". Is this normal or do i have to say its something else when getting quotes.

Also when ive spoke to all the major insurances and the supermarkets about getting quotes and they all ask what increase in horsepower as a percentage. Guess i can only guess if i have a generic remap as i wont know for sure will i?

What do you remap chaps advice please

Engine managment tune = remap.

The old term for it was chipping but things have moved on thesedays, except for the insurance companies!!

If it's a PD130 then a generic should give you 165 to 170 I would have thought. Only sure fire way to tell is a Dyno test.

Engine Chipped is close enough.

As for the percentage increase , it will vary from car to car but if you work on 130 to about 170 bhp , thats a 31% increase.

Most insurance companies have bandings for the percentage increase like 0-15% , 16-30% , 31-45% etc so it doesn't matter much if you ended up with 172 or 178bhp as long as it doesn't cross the border.

They should be able to tell you the points at which they draw the lines.

So what is basically the diffrence between a remmap and a chip?

Are chips more like those tuning boxes?

chip = remove old chip and replace with a new one.

remap = reprogram the chip without removing it.

tuningbox = neither of the above.

An ECU contains a "map". Old ECU maps couldn't be tampered with, so they had to put the map in a piggy back chip that intercepted signals to the OEM map. This required taking the chip out and soldering. Now the map held in the ECU can be replaced using the car's OBD-II port, so the physical ECU remains untouched and just the memory on it is replaced

How would they know what percentage ive had done anyway. I know that if they drive it they be able to tell its done but to what percentage they to wont know unless they dyno test it themself.

Even harder to do if the cars involved in a crash i guess.

The engine management data - how much fuel to use at a certain number of revs , how much boost etc - is stored in the Electronic Control Unit of your car.

It used to be the case that tuners would have to open up the ECU , remove one of the chips and replace it with a new one containing their modified code. This was very easy to spot simply by looking at it. This is chipping.

On newer cars , most tuners can now use special tools to overwrite the manufacturers code with their own. Less hassle for everyone and no physical changes. This is a remap.

The third option is a tuning box. They modify the signals going into or out of the ECU. Exactly what they do depends on the box itself. The dirt cheap ones just take the "amount of fuel" signal and increase it to produce more power.

Look at the tuners website and see what percentage increase they claim.

If you have only admitted to a 10% rise and it was done by a tuner who for example claim a minimum increase of 25% then it's obvious you are trying it on.

Also don't forget that power will vary from day to day and rolling road to rolling road.

A hot day on 1 set of rollers might be 10% less than a cold day on another so there is no exact figure available

Great explanations, thanks.

I knew someone with a horrible corsa that he told me was 'superchipped.' Is that just boy racer talk for my 1.4 corsa is a tad bit faster than it was?

Yes...

Superchips is a remapping and chipping company

The trend seems to be that they only load my price by about £100 to £120 but the excess has gone up a great deal. Is this abot right in your experience?

Yes...

Oh so it is a brand rather than a generic term for it.

The fog is clearing, I understand a bit more.

Yup, its a bit like Sellotape,Stanley Knife or hoover, although these are brand names they have become the acceptable descriptions for the items instead of Sticking tape, parcel knife or vacum cleaner

Superchips are a particular company that do engine modifications.

They offer pretty much the lowest level power increase as they offer a limited warranty that their changes won't blow up your engine so they are very cautious.

Also on cars without a turbo charger the increases you get are pretty small , only 5-10% if you are lucky so on a corsa thats about 4 or 5 extra horsepower - wow

Compare that to a remap on a furby VRS for the same price - an extra 40-50 horesepower.

basically , if he is showing off about a superchipped corsa he is a muppet

He has stopped talk to me since I got the furby

the only time i've ever had a superchip fitted to the n/a car was when i transplanted an 1.6 16v engine from a mk4 golf into a lupo which used the same engine management system, but obviously had different settings.... it was fine for a few months but then i started getting problems because when they soldered the new chip in they bodged it and i ended up fitting a new ecu..
