Is an 'ECU chip' / chipped just a REMAP?

[Samuel]

The an ECU gets chipped is that just essentially a REMAP?

Two completely different things, but the idea behind them is similar.

Not sure if mine has a chip or remap as I bought it with 136 break

[m4tt274]

136 break? really.

[Kebabman]

136 break? really.

Aye, it's been broken 136 times. It's a top motor...

[Samuel]

136 break? really.

Yeah , I know

[Brettles1986]

Yeah , I know

136 Brake? Why have you not mentioned this before, oh wait you have on every bloody thread you have posted.

Bet its rapid, Y0.

Was the chip to complement this beauty?

Really simply, think of the ecu like a memory stick with a word document saved on it with all the instructions written to run the engine and the parameters the engine need regarding fuel and spark etc.

A remap would open the word document and 'rewrite' the parameters and change some little bits and pieces around. It would keep the instructions the same, but be able to alter the numbers.

A chip usually piggybacks the ECU but sometimes replaces an existing chip. It works just like the remap really, it removes a section of the instructions and pastes in some pre written revised instructions.

Replacing the ECU and having a custom map allows you to totally start from scratch and write your own instructions and parametres. Someone who is shit hot will make a car what it is by doing this, though an idiot will ruin one.

The problem with all maps and chips is they are only as good as the guy doing them and often cars will share the same ecu, many use siemens ecus, and most maps are swappable amongst the ecus. For example i had a friend who believed he had a bora tdi 140 and had a barry boys cheap place remap it to 180, they just plugged it in and mapped it. It turned out he had a 115 tdi and god knows what map it has on it but its already eaten a turbo and a headgasket in about 3,000miles.

Silly really, wrong map and power choice, 180bhp on those cars shows so many weak points its unreal.

I should mention that i dont discredit some remappers, there are certain companies that will design a custom map for a specific car and then only sell that map to people with that specific car, like Revotecknik who do all the focus ST's, im sure there will be someone with a bad word to say, but you dont hear of many. They dont remap that many models and the ones they do, they charge a lot for. But if i was in the market for a remap, i would want one i could trust.

These chavvys on facebook you get inboxing you with "il remapz ur VTR if u want for £65, be sik, map it 4 power be 150break easy" can piss off.

Mapping quality depends on the quality of the mapper and the time spent, lots of places will give you a map for £150-200 but they spend around an hour or two on it which isnt enough to give a quality map. IMO a map on an N/A engine without any internal engine components changed is a waste of time and money. NMS are a company a hugely rate they charge over £100 an hour iirc for mapping

[welshpug]

Its not so much the time spent per car, but time spent on that particular engine knowing its specs and what kind of map it should have for it to work efficiently.

yes you do need a mapper that knows your ecu software, but you also need someone that knows your engine type, no good taking a TU5 to someone that knows Jap turbo motors, unless they also have experience of TU5's!

Chatting to Sandy about will DiClaudio's newest spec race engine (a refresh and update of the existing lump to more recent spec) because Sandy has built nigh on a dozen of much the same spec iirc, it only took an hour to sort the map on a fresh engine as he could load a map he had used previously, check that all settings etc are correct and go through the load sites making sure all is right.

only engine dyno time can give you that, Sandy is lucky to be able to work with the likes of John Read, infact I think most if not all of John's recent engines have a Sandy map, so sandy knows GM Ford and PSA :D
