Unmapping a car
hi
i suppose it would cost as much as a remap to unmap a car???
reasons.....
1. i am thinking of upgrading from a bug wrx to hawk sti
2. i would like to have the car standard-ish to start with to enjoy the power gains i will get
3. then return to full map if i want to in the future
i suppose (i dont really know) that mappers keep your maps on pc??
thanks

Would be cheaper and easier to get a standard ECU. But it wouldn't just be a case of un-mapping. I would imagine the reason the car you would buy with a re-map, is because there are other aftermarket power mods. And running on standard map with those, wouldn't be a good idea. So to get to standard, you'd have to potentionally remove decat pipes, headers, maybe a turbo etc.
Just test drive a standard one if you wan't to find out.

AFAIK uprated fuel pump and decat exhaust? it would prob be a good idea to speak to the original mapper and ask his advice, i would imagen good mappers keep a record of cars they have done??

They probably do, but I can't imagine the mapper would say its ok to have a standard map with a decat. They'd probably give you a revised map to cater for the decat, but that won't be standard.
Either way its seems like a lot of bother, just to feel the standard power.

thats why i was asking to see if it would be a lot of bother
lets say the car was running 380bhp thats really nice but i was thinking along the lines of NOT having Christmas, Birthday, Easter and New Years all rolled into one. if you can understand where im coming from?

I dont understand.
Why not just exercise restraint with the right foot?
if however you cant, then you would want the power anyways.
Sorry, and I'll dumb down my post to be nice but this is totally daft thinking.

not really daft??? i am going from a standard wrx to a 2.5 sti a big jump in anybodys book
there are several things i need to take into account (besides the fact that all my right shoes have lead in them ) the car will be used daily 20K+ miles a year so not just a weekend toy, will say 380bhp and 400+ torque be suitable for everyday driving? if it is, then great as we all know i takes no time at all to get 'used' to the extra power and the 'trouser twitching' soon fades away so, taking cost into consideration, 300bhp to start with 340 say in year 2 the back to the 380 in year 3. Each power hike would give me something to look forward to if you know what i mean?

I do 20k miles a year and have done two modding steps - the first to 340 hp, the second more recently to 380/400 hp.
After 60k, the car will be returned back to stock
The 2.5 engine is so flexible that both power hikes have been used in either steady commuting mode or something a bit more enjoyable.
The hike could have been made straight to the higher level without needing a pause.
No real need for switchable boost mode TBH.
The std ECU map is held with my local tuner who can put it back. The alternative is to find a std ECU and flog the tuned one, as it has some value if holding an Ecutek licence.

You'll have no issues running a 2.5ltr at that level of tune as a daily. As mentioned the engine is very flexible and even tuned can be ran sensibly for better fuel economy or booted.
You will have major problems running a 2.5ltr with a decat on a standard map. You can get away with it with a 2.0ltr sometimes but I've been told it is a big no no with the 2.5ltr.
Sorry, I really don't understand your thinking on this one.

ah - I didn't read all of Steves replies fully.
There will have to be some level of mechanical upgrades to even get to the first level of tune you want.
I keep all the std parts in the loft and come the fateful day , I put them all back and get the std ECU map back on.

the reason im asking is that i have seen a very nice car for sale but i is running 380bhp i was'nt sure if this level of tune could be used on a daily basis hence the de-tune option, there are other issues like insurance and fuel (not that its ever bothered me ) but the car would be used as a company car and i get enough comments each month when the fuel bills come in the others use 'oil burners' YUK! also as mentioned a gradual build up of power (like butty) would have been nice (eg. power get used to that, then more power) a bit like getting a new car once a year
thanks for the comments guys

or the cheap option would be to connect the turbo to the wastegate so running wastegate only pressure then when you get used to that connect it up as it should be...
Seems daft though - why buy a more powerful car than de-tune it and possibly risk blowing it by running it on std map but with mods that could react badly?

now, unless i asked (theres a lot of people on here who know the ins and outs of tuning) i would never get to know would i?? as said the 2ltr car is much more forgiving re. mods but i have no experience of the 2.5ltr....so i asked so there
i must be the first to ask 'how do i make a scoob slower?'
from the helpfull posts i can now consider buying the car not too thirsty and more important can be driven everyday without giving me a heart attack
one thing that i did'nt mention is that when i was looking at my first scoob 8 years ago i had a test drive in an Rally Art Evo4, after 2 hours i got out and thought that allthough it was a GREAT car (the active yaw is amazing!!) i really could'nt live with such a tuned car on a daily basis, it would have drove me nuts! Hence my post....
thanks again

Rally Art EVO4 - is that the Rolf Harris special edition
I must be suffering from cabin fever and keep on missing vital parts of the issue.
I'd buy the car as is and not bother detuning it. The 2.5 engine really is docile and driveable even at 380 hp. Its not as if you are moving straight from a 1.1 Fiesta?

Rolf Harris lol
Seriously it was an insane car and the handling i can understand why people move to the 'dark side'
BTW it not an issue now because i now know that the car would be usable, as the old saying go's 'if you dont ask'
