Race Chip Pro fine tuning

[tjk]

Hi there I have C250 CGI BlueEFFICIENCY, 1796ccm, 150kW (204PS) I'm looking for ppl who tried Race Chip Pro on their rides. (http://www.racechip.de/racechip-chip...CY-3919-r.html) This little box has manual adjustments - see image attached. The second (right) dial is responsible for rpm range in which the power increase (left dial) is active. So since C250 gives less power on lower RMP, I'm now testing setup at 0-0 positions of the dials. So far I ran several tests with Dynolicious app for iPhone. I'm not sure about the settings I enter (drivetrain loss?) coz even on stock I don't get close to 7,2 seconds (0-60) and 204HP.. might be doing something wrong. You can see two images attached - with and without rache chip. By now I can say that the chip does provide some torque but does not affect the 0-60 run time. Will keep this post updated. Gotta run some more tests on same setting of the app (however, they don't affect the time).

Soo, some more detailed results. Stock vs. Race Chip Pro

Same day and time, same place, drive in S mode, ESP on


Dynolicious setup:
Rollout = 0
Trigger = 0,10G
Ride setup:
Weight = 1700kg
Drivetrain loss = 20%

I made 3-4 runs for every setup, below you'll find the best times for each setting. You can find what the chip settings are about in an attached image in my previous post.

Chip setting; 0-60km/h time; 0-100km/h time; G value; HP value;
no chip; 4,25; 8,41; 0,52; 199;
C-0; 4,17; 8,19; 0,54; 203;
C-1; 4,20; 8,21; 0,56; 207;
E-0; 4,22; 8,22; 0,56; 205;
D-1; 4,13; 8,24; 0,56; 201;
4-C; 4,28; 8,41; 0,56; 198;
4-0; 4,29; 8,45; 0,56; 201;

This all means that there is no perfect solution, and putting the settings up too high will even result in worse power.
I'm set to D-1 now.

Attached you can find the graphs comparing stock vs one of D-1 runs. You may see the difference. The D-1 curve is smoother. So far I cannot say that i'm satisfied with the purchase. If someone has a better experience - please share.

Next time I will post results with BMS Intake + Race Chip Pro.

You did a 8 second 0-100km ? You sure your driving her right. Thats a toyota corrola time there. That chip is crap than, there is no way you shouldnt see some improvement in that 100km time.

Well, this all is timed on an iphone, so there is no way it gets even to the stock 7,2 time.

with power break, by the way, I can do 5,8 secs to 100km/h
