Default 0-60, 0-100

Hello friends,
Sorry for writing late. Was very busy in work, didn't get time to check posts. It is 3 weeks now since the box is installed and the car is performing excellently. After sales service of RD is really great. They call me every week and take feedback about the car's performance Engine now likes to be revved. In P1/P2 setting in second/third gear the engine makes a nice humming sound after 3000 RPM.
Today i met Karthik and tested 0-60 and 0-100. Car is still running on 175/65 R14. We did 3 speed runs. The first run was with AC on which we considered invalid. We then did 2nd and 3rd run with AC off. Here is the data:

2nd run data:

0-60 in stock is 5.20sec.
0-60 in P2 is 4.49sec.
Difference is 0.71sec

0-100 in stock is 12.31sec
0-100 in P2 is 10.33sec
Difference is 1.98sec

3rd run data (see graph):
0-100 in stock is 12.39sec
0-100 in P2 is 10.40sec

There was a lot of wheelspin in 1st and 2nd gear Traction was available only in 3rd gear. This is evident from the graph. Till 20kmph the RD graph is actually lower than the stock graph and after that it picks up. Karthik said we could have achieved 0-100 in 9.5sec if the tires had been better.
I've decided to go for 195/60 R14 Continental CPC2. Any better options?

Good choice. I have the same tyres and recommend it to you. One small thing is that i had BF Goodrich G Sport of the same tyre size before this it had better grip at speeds above 170kmph but did not corner well enough but then again had good lateral grip i mean we could skid and slid without any problems. The BFs where very very hard and made for uncomfortable ride. As for the CPC 2 it is quiet comfortable but then make your mind for a little harder ride.

That's some good numbers there, a straight cut of 1.98 secs off the stock ECU's timings. However the million dollar question, what have you done to improve your braking ?

At what rpm is the difference really felt ?

Tuning box wont ever change the rpm where a particular speed is achieved because that is dependent on the gearing.
Are you sure its 100 kph @ 1800 rpm? I can bet my life on it that it can't be low. It cant possibly be geared so high in 5th

Actually getz 100kmph in the 5th gear is at around 1800~1900 rpm. The turbo kicks in at around 1800~1900 so it is quiet possible . At about 3000 rpm in 5th gear you get to 150kmph .

But, the speedo can show different speeds depending upon the tire size.

Better tyres here would mean better timing right, due to more traction? So sub 9sec possible ?

Now we need a comparo between petes and RD

You may as well get Advan Neovas! It might slow down your 0-100 times, but you will have astonishing grip at the corners.

And if you take care of it well, it might last you upto 30k kms.

Turbo kicking has no relation what so ever with the speed car is doing. Its a function of gearing.

If Getz does 150 kmph @ 3000 rpm then we are looking at 2000 rpm for 100 kph and not 1800

Here are the calculations

150/3000 = .05
.05 X 200 = 100 kph

.05 X 200 = 100 kph
if its a downslope then 100kph at 1800 is possible. afterall the error is only 200 rpm which is insignificant in these engines.

Which gear ? What is the factor 200 ?

In 5th Gear
100kph - 2000rpm
120kph - 2500rpm
140kph - 3000rpm
160kph - 3500rpm
180kph - 4000rpm
200kph - Couldn't see anything !!

@headers... No even if its a downward slope. The speed == revolution of the gears which would remains constant, downward or upwards. The only case in which this ratio would differ is in case the clutch is slipping and not working properly.

@kpzen... Lemme explain in a more layman way. The speeds are all in 5th gear so the gearing remains constant.

150 kph and 3000 revs would mean 150/3000 kph per rpm == 0.05

Now speed at 2000 rpm would be 2000 X 0.05 == 100 kph

Guys from Bangalore have inherent advantages WRT RD's products. The man is just a phone call away. Good to hear that you are satisfied with the sales / install experience.



I wasn't even aware that the box had an economy mode. Good stuff, different settings for different driving conditions.

Tell us more about P II Mode



If an overpowered car like the Getz CRDi struggles to climb, that setting must be running real lean.



Do share the price here itself, we insist. Posts with price included can only increase the value offered by your review.

Congrats on the car + powerbox, and drive safe. Top priorities for you ought to be a stiffer suspension & wider tyres.
who idea is this i mean the economy mode also option give to the user
who provide component samples from china to RD
