Group ECU Reflash/Remap ??

[John_Smith]

I have spoken to GT Auto, after the group dyno run the other day with regards to my erratic air fuel ratio and how to gain more horsepower and torque. They have new service - ECU reflash/remap for Continental cars. The list of BMW cars supported is as at the link below:http://www.gt-auto.net/images/stories/2010/files/GTAFlashCarList.pdfGT Auto charges RM 2,800 per car. This includes:1. Dyno run - before to register base map / base horsepower and torque figures2. ECU flash 3. Dyno run - after mapping until dyno registers gain in horsepower and torque - this would also mean multiple numerous flashes in between.If we are able to get 10 cars, we will be able to get our ECU remapped for RM 2,500. Once confirmed, you would need to pay 50% deposit to GT-Auto to ensure no FFK. The sooner we can fill up the 10 space, the earlier that I can work out a schedule with GT-Auto.Let's see some hands...1.2.3.4....Some FAQs with regards to ECU flash..1. Can I use map from a other car to my car?No. This is because ECU flash is all custom for an individual car. The same map is never loaded onto another car even though they are sharing the same engine and platform. Even if they are still in stock form, every single car is unique.2. What is there a need to have the car mapped on dyno machine?The importance of having the car mapped on a dyno machine is to show that the gains in horsepower and torque is real and measurable - i.e. not butt dyno.3. What if my car did not register any power gain after remap?If the car is still using the stock map from manufacturer, then GT-Auto will not charge. However, if the car had been pre-loaded with other car's map, there will be 2 options going forward.Option A. To optimize current existing map, but if the base map is very bad such as the air/fuel is way out of place or the timing is overly aggressive, then it'll be more like trying to fix a problem first before even trying to make power. Usually, in this kind of scenario, it is better to start with a blank map, which brings us to option B.Option B. Put in the base map from the manufacturer and do a base run. Modification will be done from there. 4. How long does it take to flash my car's ECU?Flashing is fairly quick, but the whole process inclusive of dyno runs, before and after, is at least 1 hour.Some pictures of ECU reflash/remap in process..http://www.facebook.com/album.php?aid=290005&id=193126482007

Er, sure can do ah? Can they do force inducted BMWs?

Do they have the original base map for all BMW models & cc?

Btw, i saw the Carrera S on dyno yesterday.

Is this ECU/Remap similar to the Remap from Benard of BVO?? GT Auto is charging RM2,500 for which model of BMW??

 

[astroboy]

E90 316i also can remap!!

They use same remap computer as banard BVO , the advantage of GT racing is their Dyno Machine is lying beside him so u can see the result on the spot.

To me, the price a bit on higher side compare to Benard BVO. M54 engine (+-1450).

GT (Thomas) quoted to me RM 1500 for M54 engine for 15 to 45 minit time tuning ( according to him it is basic tuning) and RM 2800 for the full tuning which will take more than 5 hour.

To all sifu out there or who had experience with GT racing please post ur Dyno Tuning before & after so we can do comparison in between full tune and half tune:rock:

Wealso can Run Dyno Test ( make sure they capture max power out put ) and get the result & email to Benard BVO.so he has the idea to tune ur car on the street behind One World Hotel. ( If he came la hehehe)

The price is regardless of engine capacity, regardless of BMW model. That means, it's the same for 1.9cc or monster 4.0 twin turbocharged or hybrid 2.8 supercharged. As I understand from them, they have base map for all BMW model (I would need to reconfirm this).

I think the main advantage of GT Auto is they have a dyno machine and will flash until there is a satisfactory gain in output. I.e. full tuning...

this is very very tempting

This is the list of available base maps from GT Auto: http://www.mediafire.com/?2o1x60cbp8ghq8z

The tuned map, so to speak, is unique to your car. It can't be flashed to another car as parameters would be different. Also, I got to know that the dyno machine used can be used to simulate different road conditions - uphill climb, downhill and other scenarios.

Tempting!
