Good evening fellow enthusiasts I had my car on a dyno today. To say I was pleased with the results would be a terrible understatement

The car has 1,500 miles on it now. Here is the best run from today. We got 176.1 max power and 183.4 max torque. The four or five people around the shop after the run, as well as the owner, were quite surprised at the power this engine is producing. Including myself :p

Randy, the Upsolute chip comes with a 30-day money back, no questions asked guarantee. I shall have the dealership make the necessary adjustments to the fuel settings. Will they ask questions when I tell them I'd like them to alter the settings for fuel and timing? And WHAT about the fuel and timing will I ask them to adjust?

Or are you saying only to alter the fuel and timing settings manually, via the dealership, to achieve the same results as modifying the car's program?

If I do stick with modifying the chip, I'll have the car on the same dyno again to view the results.

Buellwinkle, I like the idea of modifying the crankshaft pulley. It sounds like the most reasonable thing to do to gain more power. I'd like to have a balance of increased power and reliability at the same time.

Once a reasonably priced crankshaft pulley becomes available, I'll be all over it. A dyno will be performed after THIS upgrade as well

Anyway, here's the stock dyno.

Thats an impressive dyno run! would not properly breaking in a car have an effect on power?

I'm running at setting 3 on the fuel and the 93 octain port on the timeing. The dealer should not have any problems finding the settings or changeing them for you. Although they may not even know they are there (they should). This does not do the same thing as a chip does.

I will be intrested to see how your car responds to the chip. What was the temp like were the car was dyno'ed. I have only run mine at high temps like 95 and up.

Was your first pull you best?

goodKat: Can you give me some information and addresss where you're getting the Upsolute chip?
Being on the east coast, I think the NJ is closest place I could go to get the chip installed. Thanks.

Now THAT'S a dyno graph!
HP and torque vs. RPM- that's useful info. Thanks.

I can't understand the previous charts showing HP and torque vs. MPH...and shift points...what's that about?

PS: How much does it cost for dyno time?

dmichael

Why only 176.1 Max hp and 183.4 torque? Should you not expect that you'd get 192 Max hp and 200 torque like MB states?

vadim

These results have been measured at the rear wheels, whereas the "advertised" figures are measured at the flywheel. The difference accounts for power losses in the drivetrain between the engine and the rear wheels.

dmichael

Wow - thats a good 10% of hp and torque absorbed in the drivetrain. Is that average for most cars? What would you estimate the limits would be in terms of an extreme high and extreme low percentage?

DtS

What I have heard, 10-15% loss of power from crankshaft to rear wheels is quite normal.

tommy

The loss for a slushbox is greater than that for a manny, so everyone should keep that in mind when they're deciding on which to get.

Manual wins again!

dmichael

The Dyno chart in this thread was done with a Manual Transmission.

Lynn

Many dyno operators figure 15% to 18% drivetrain losses for a manual and 18% to 21% for autos.

I'm getting the chip from John Achille. He is a distributor for Upsolute. His number is 732-681-7666. $325 for the chip, $25 for installation. He should be installing the chip on Saturday, and I still need to go back to the dealer for my plates, so I'll try to have the fuel and timing settings changed before Saturday.

I probably won't get to dyno the car again until next week, so we'll have to wait for the results. In the meantime, I'll let you all know how it "feels" after it's installed

I'm pretty sure I got ripped on the dyno, but they know what they're doing and sometimes that's worth a few extra bucks. The charge was $125. The first two runs were done warm. They had a fan blowing underneath and in front of the car to cool it off before doing the third run. I believe the third run was the best. They gave me a fourth pull, so I guess I got my money's worth. To tell you the truth, as long as the numbers on the graph keep going up, the $125 is well justified

The temperature during the runs was approximately 68F.

the tuning company in my area recommend pully upgrade (don't get me wrong... I am all for it) but I am also interested in the chip tuning...

But I was told that you can't chip-tune C230K... cuz the ECC, or whatever the computer control is, basically will adapt to driving style (true fact)... so he's telling me that the good dyno result you see after chip-tuning comes from disconnecting the battery and clearing the computer's memory... then running it hard... thus produce good number... donno... any comments on this?

renncpe

The ECU is memory resonant, but a good chip will change the parameters that the car will operate under. Values like Vmax, and max RPM, Fuel map, timing to name a few are changed the ECU will then develop a memory using these new values. In a new system like in the C Coupe uses these values they need to be discovered and changed. There is no menu in the system that can guide you through. Many tuners buy the original code and modify it paying a royalty for each modified chip sold. Others will try and record the out puts and modify from there. I can’t say that this is not as effective (hit or miss), but in general there are fewer chances of problems down the road when the original coding is used to produce the new variant. (guess which one cost more?)

humm....I will post my dyno when I go back to the shop...the last pull that we made was almost 268 rwhp......

renncpe

Is that with the NoS That will work out to 316 HP at the flywheel.

Randy

benzy230

Actually its with my smaller pulley, larger intercooler, hard piping, HKS exhaust, and a 75 shot (wet kit)......we really dont have an exact number on the hp at the flywheel.....have you got N2O on yours yet??

revstriker

Benzy230, just wondering what the status of selling your car was? Didn't you post awhile back that you were selling??

Buellwinkle

Benzy230, you're back! Is your mechanic ready to start selling pullies yet? Lots of us are waiting for a cost effective solution? Did you experience any belt problems or pre-mature wear with the smaller supercharger pulley?

benzy230

whatsup guys!! The car is still for sale. I had a kid that was going to get it...but his parents did not come through.

My mechanic (Rob) is currently working on some other cars as well. So far mine has held up with only one belt problem. We havent noticed any wear on the engine, and the compression is still as good as it was new!

The N2O has helped out a bit, and hasnt made any noticable wear either. I will keep you updated as to how everything is going! So, what all have you guys been up too??

goodkat

Randy, just spoke to the service department where I bought the car. The person I spoke with thought I was from another planet when I asked him to change the fuel and timing settings. He said there was "no way" to change the timing settings.

What can I do? Is there a way I can better explain what I want?
