Hi all,

Just wondered why most of you map after every mod, is there a particular reason or is it just preference?

Also do you map after every single thing or is it just major things, i.e i have a dump valve waiting to go on my impreza, would you map after that or is it just major mods that you would do it after?

Cheers for any info/advice

Also, i noticed that some ecu's can't be remapped, i presumed that all of them could be in this case can mine be remapped on the standard ecu? I have a 2001 uk300

Cheers chris.

 

whan you map your car, you are wanting to get the best out of it, power, safty etc.

if you change something like going from standard headers, to aftermarket ones you would need a remap, as boost, fueling, air flow will be all different, and could cause the car to run lean, less power and mayb unsafe. so you have a map tweek to put everything right again, so the car is safe and working well.

for little mods like a bov, i would not have a remap, only for big things to do with the engine, exhaust, injectors,turbo etc etc.

with your standard ecu, i think you can have it ecutec, or a stand aloneecu like apexi and many others.

from havinf a remap, you will not only notice more power, but a better driving car and normally more miles to the tank as well.

2 mappers that i can recomend (that i have used) out of many good ones are Paul at zen performance, and Simon aka JollyGreenMonster (on scoobynet)

hole this helps

 

perfectly put DAONE

 

Cheers for that DaOne, so if i put a cat back system on it am i best off getting it mapped then?

(sorry for all the q's but i wanna get it right with this one as the last turbo i had had a few "issues" with the mods i did )

 

Again, the advantages of having a standalone ecu system that adapts to suit. Score!

 

Just had a look on jollygreenmonster's site, why is there 3 different types and 3 very different prices for the remaps? i.e one is 300 one is 650 and one is 1000
i know you are meant to get what you pay for but really is there that much difference between them?

 

The mapping cost are due to the different supplying and fitting the different after market ecu's.

The one you should be most interested is the Ecutek one. The initial outlay of £650 pounds is to buy the license for your ecu. Re-maps then will only cost a fraction of this. You only purchase the license once.

Ecutek re-map costs £650 the first £200 goes to Ecutek.... (a later re-map costs less as it's at least £200 cheaper.)

The rest goes to the mapper, who "locks" your ecu so no-one else can read/alter it, as some messed about and blew engines and then blamed the mapper..... this means you have to go back to the same company to alter the map later....
Mine was done for a FMIC and exhaust change to get the power up nicely....

Next step has to be exhaust headers and turbo, together as each needs alterations to the map, so two at once is better value.... not mentioning bigger injectors....

To answer your first question about the mapping, I now map my own for any new mods.

What I find is that after fitting the new mod, whatever that my be, I will actually be taking logs to check AFR's and knock etc. Now, unless you have access to this software/equipment then a mapper is needed. "IF" there is a need to change the map then they will, otherwise its a check to see if all is well and safe.

So frequent mapping means "checking and adjusting" if neccessary.

 

the website has some detail but not all.. if that is confusing then perhaps I should access adding more detail..

sorry

 

that's not 100% true.. you are still free to take it elsewhere but the new mapper cannot view the current map on the ecu.. but is able to remap it from a fresh etc.. sorry if I sound picky but wouldn't want it sounding like monopolised to only use the original mapper etc..

Simon

 

nice explaination

the 2001 is remappable with EcuTek as you say..

Apexi is classic only

Simon

 

Not strictly true, I cannot flash an ECU that has been flashed with Ecutek since the lock was introduced a couple of years ago leaving the customer no other option but to return to an Ecutek agent.

With a MAF based system like the Impreza runs, small changes in your engines Volumetric Efficiency will be catered for by the ECU however it wouldn't neccessarily be optimal and can only run settings from data that is already within the ECU's 'maps'. New data must be entered into the ECU to cater for larger changes to VE and this data optimised to ensure good reliable operation of your engine.

 

the poster was implying he was restricted to the original mapper which is not so.
If you have an EcuTek licence why would you not want to go to an EcuTek dealer? there are plenty enough to choose from EcuTek Authorised Dealers including Prodrive.

Simon

 

The most common scenario I've come across is a customer who has purchased a Subaru that has previously been Ecutek'd and they want us to carry out some further work as we are their preferred tuner.

 

Personally i think its a bloody cheek that EcuTek lock the ECUs of vehicles without notifying the customers...

I know i'd be pretty unhappy with that.

 

if you had had a re-map and then changed just your backbox would it need re-mapping or is it to small a mod to make any difference?

 

wouldnt make a difference ste just for the back box

 

Its mainly to protect EcuTek's investment of thousands of man hours accessing ECU's and producing an excellent tuning system which is also used by Prodrive.
Before the lockdown, there were certain software hackers stealing EcuTek maps to use in an open source type application. Its understandable that the hackers are a bit upset by this change

Any Ecutek mapped ECU can be returned to std and the licenced access removed if required.

Do ECUTek not reverse engineer then to access the ECU, or do Subaru just hand over the maps then....... dont answer I know which it is....

 

How do you get around this lock then?
My original remap was done by Bob Rawle. Say I wanted to try my own hand at mapping (at my own risk obviously), am I not able to back up a copy of Bob's map, load up a base map myself and have a play with that and then reload Bob's map at a later stage?

Seeing as I own the ECU in my car, surely ECUTek have no right to lock this?

(I can understand why I wouldn't be able to view inside the map, but I am not worried about that).

 

Would ECUTek then refund the license fee?

It would all be much easier if ECUTek just made their software available for sale to whoever would pay for it and make people sign a disclaimer for use at their own risk.

 

So if i wanted my car remapped, as it got a remap before i got it and cost £950ish with remap, superchip, full decat, would i have to go back to the same place to get another map to get it cheaper, Its a ECUTek map

 

Surely all they need to protect are the rights to their software.

The map is written by the mapper. Unless EcuTek mappers are just uploading a base map written by EcuTek and charging for a full service?

Personally i think that the ECU is owned by the vehicle owner and should not be locked without their permission.

 

oops sorry didn't mean to start anything with this thread just want to make sure i go down the right paths as the last turbo car i had had major issues (which all happened after a bad experience with a remap) hence my caution with this one

 

Remap after every significant mod. (if it isnt significant - why are you doing it )

As for the ecutek vs open ecu argument... I know which I prefer

 

Is there no mapper using open Source Software, eliminating the monopoly of the GEMS and ECUtek's of this world.

I have an open source mapper from a reputable mapper for a fraction of the cost (he will also map ECUtek as well if you wanna pay your money out), because I did not have to pay for a licence and I can also view the map anytime I want.

 

Zak at Mocom Racing doesnt lock the maps. He doesnt use open source software though but is not tied to ecutek.

 

Playing devils advocate here, but what happens if a map is left open and someone starts messing with it and blows the engine as a result..?

Say they then went back to mapper claiming a bad map resulted in the failure..?

I know the mapper can compare the map on the car (with one stored on his laptop etc) to see if it's different, but what if the other person, who messed with the original map, changed things back after the blow up..?
