Mapping

[scoobyfuzzy]

hey guys, just a wee question ive been wondering about, most guys on here go2 MR F for mapping of their cars, how different is that to piggyback chips etc? pro`s and con`s?

Andy f Pros, you know the mapping has been done correctly and with the safe running of your car in mind. Cons non except wanting to drive your car even more.

Piggy back chip fools the ECU into thinking that certain things are happening that aren't, and then passes on information to other parts that the ECU isn't sending!

The chip has also been designed with one specific set of mods in mind, so unless you're running EXACTLY what it was designed for then you never know if it's running 100% or not.

By getting a custom remap on either a standard ECU or a replacement one you'll know that what's being done is tailored for your car. You get the most performance, reliability and safety. It's the best of everything!

just curious, cos wot ive learnt about the piggyback chips, is pretty much similar to wot uve just said

Fuzzy - for me it comes down to why spend all the money on the mods then skimp on what's controlling all of it? A custom remap unlocks the full potential of your car and doesn't leave anything to chance.

well youve learned wrong who told you this somebody trying to sell you one perhaps? , if the chip is so good have you ever wondered why none of us seem to use them and prefer to get the ECU mapped instead?

bottom line is

chip= your engine running on borrowed time, ultimatly leading to the big bang (it might never happen but there is a HIGH risk)

remap= your engine running better than it did when it left the factory with better MPG increased power etc etc (depending who mapped it offcourse)

Just wondering if you are asking that as a Dastek employee or just for your own info

I used a Dawes device when I wanted to up the boost on my old classic which was a cheap way of doing what a piggyback can do. If I was doing it on the 06STi I'd have it remapped properly. If the choice is £25 Vs remap price then money might come into it and you go for the cheap option 'cos you can't afford the remap, but as far as I'm aware you pay more than half as much for the piggyback as you can get a remap done for so it gets a lot closer.

No way I'd risk a piggyback and having to pay as much as that when a little extra gets a fully customisable bespoke map tailored to the car.

hi andy, not asking cos am working fo dastek, just wonder how different ur mapping is to the dastek mapping, obviously with working at dastek i know about they piggy back system n that, but didnt know the way u map cars, just curious about how different the two are, thats all, not trying to step on any1s toes or anything, as i said, was just curious

I think the point is fuzzy that the Dastek 'mapping' isn't mapping. A piggyback chip is just that, same as the official PPP upgrade from Subaru, it isn't mapped to your car, it is the best guess at how it will perform with the various PPP elements on it but no two cars are alike, you'll know that from rolling road sessions at Dastek, too similar cars will make different power etc.

Andy actually does a unique map for the car and how your motor actually drives, something a piggyback chip can never do.

Depends on whther it's just a chip, like scoobyecu which is set up for certain mods and not specifically for your car, but certain piggyback ecu's like the greddy e-manage can be mapped to suit your car altering fuel and ignition timing.

Still doesn't seem to be as good as a fully remappably ecu or ecu tek.

[Power Junkie]

I have a Dastek Unichip+Boost module. Its ok really, but I just feel the EcuTek on the standard ecu is better, So this is what i will be going too soon. the car dirves fine but just not the same as an Ecutek mapped car. Fooling the ECU I dont think is the best thing anymore. Cant wait for the EcuTek map.

Come on guys, all of this is totally incorrect. Please read up on programmable piggyback ecu's before you announce this kind of stuff to the general public.

he just mentions piggyback chips, not the programmable ones

Most of the quotes I used are referring to the Dastek Unichip, which of course is programmable.

How many "piggyback" chips/ecu's are not programmable? There are a few types where you can "piggyback" an eprom on top of another one actually on the board inside the ecu, but it seemed pretty clear these were not the type under discussion here. If it's just me thats got that bit wrong, then apologies.

yeah i was meaning the dastek chip

I spoke to a guy that was once a member here, he had a dastek chip originally, then he went and got Andy F to fit & remap the Apexi ecu.

Difference was night and day, a whole load better, much smoother across the rev range, much smoother boost curve etc.

IMO, why p*ss about with a programmable aftermarket ECU if the OE one will do the job just as well. AFAIK an EcuTEK remap is a fully customisable map for the car you actually have, without buying an aftermarket part.

Now if you have passed the limits of the OE part then I can see the pont in having an aftermarket part, ie so you can have a 1200bhp monster or something... but why would you p*ss about having something like that if you were looking to have something at say 500bhp[1] or less?

[1] - Personally have no idea what figure the OE chip has issue with, actual figures may be higher or lower... see banking BS for more info
