Unichip dyno sheet
here is the dyno sheet.
a few things. it says 50 shot but i have a 75 shot. it says 4th gear but i know they did the dyno in 3rd.
the numbers are SAE corrected for flywheel hp and tq. i was able to look at the uncorrected numbers on the dyno computer screen and the max wheel horsepower was 244 w/ unichip, 301 w/ unichip and n2o. the way this machine measures output shows my drivetrain loss at ~ 12%.
this is the email from Jack that came along w/ the dyno chart.

Matt,
Here's the dyno sheet for your car. It's quite a few lines and bears some explanation. Remember, dashed lines are torque and solid lines are bhp; everything is SAE and flywheel corrected. The Light Yellow lines are stock/dry, the Red lines are Unichip/dry. The Gold lines are stock/NOS and the Orange lines are Unichip/NOS.
The biggest "weird" aspect to the chart is the large disparity between the Gold and Orange lines at low rpm; as we discussed, that results from the manual "power roll on"
required with the stock NOS configuration to not bend the engine or smoke the tires and the progressive/Unichip controlled NOS application on the Unichip runs. Note: the stock NOS numbers at low rpm very much represent us trying to not hurt the car at low rpm and can probably be significantly higher when an experienced driver who has lots of NOS launch experience drives the car. Best case, however, would be drawing a smooth line from the stock NOS curve at 4500 rpm back to where the other 3 curves (dry/stock, dry/Unichip, and
NOS/Unichip) are essentially coincident; that represents a theoretically perfect stock/NOS launch and you can see you're still making far less power than with the computer controlled Unichip launch.
The other aspect of note is the way the Unichip/NOS curves drop away to the stock/NOS curves near redline again because the Unichip is automatically shutting the NOS down 400 rpm prior to redline.
Average gain dry was 4.7% across the entire rpm with a maximum gain of 8.8%, both above just the hardware modifications with a peak of 277.7 bhp and 221.0 lb-ft. The NOS gains were average 23.9% across the entire rpm range, with a peak gain of 86.1% and a maximum of 342.1 bhp and 287.4 lb-ft (calculating only data above 3000 rpm since you'll only be below that in 1st gear, the numbers become 10.5% average across the rpm band and 40.2% peak gain).
Please let me know if you have any questions.
Cheers,
Jack

Wow!... Wow! ...Wow! the gains are there...
Let me say the following:
Other than the fact that all numbers were nornalized so that max stock fly numbers are 260 HP (the 12 % correction factor), it seems good.
So back to SAE Wheel hp and torque:
NA no UNIChip: Max SAE Torque: 184 lb.ft of torque, Max SAE WHP: 228 WHP
NA + UNIChip : Max SAE Torque: 193.6 lb.ft of torque, Max SAE WHP: 243.76 WHP
In a nutshell, your CLSresponded to the UNIChip with 10 lbft and 10 WHP gain.
With Nitrous:
NO no UNIChip: Max SAE Torque: 242 lb.ft of torque, Max SAE WHP: 294.8 WHP
NO+ UNIChip : Max SAE Torque: 253.44 lb.ft of torque, Max SAE WHP: 300.96 WHP
I see 20 lbft and 20 WHP gains.
That gain is worth the asking GB price of the UNIChip!
Congrats!

The awesome thing is not just a 10whp/10 ft-lbs max gain, but a ~10whp/10 ft-lbs gain across the entire powerband ...
From 3000-7000rpms you'll notice roughly those same gains! Should do really nice for our mid-range which doesn't benefit too much from headers or intake.

Holy Torque Batman! I need NOS! HAHA...... but really.
I am confused though. It says your bhp with I/H/E is only 260 flywheel. Shouldn't that be closer to 290-300? Our cars come stock with 260. I understand the gains are there, just curious why the bhp is only at 260.

Stock our cars make 260/232 but only put down about 200/180 to the wheels... ~25% powertrain loss.
A 25% powertrain loss would put a 244whp @ about 305 flywheel hp.. Max torque is about 220 ft-lbs on their dyno, about (12% less) ~194 ft-lbs to the wheels, (25% more) ~242 ft-lbs at the flywheel ... Seems kindof low on the torque, unless the torque figures weren't corrected *shrug*...

That looks good 
You might not have too much gain while using N2O, but it will be safer to use considering the UniChip will retard timing!
It looks like the 'droop' from 6400 RPM to 7000 RPM is fixed... that's is basically all fuel control - good job!

i have to find the right stretch of road to really open the car up on the n2o. it will get to 110 really quickly now. i need better brakes, steve. not nearly as bad as you do though. 
i like the 22hp and 18tq. gain at 7000rpm.

But I decided to wait for several weeks to begin the brakes unless I clear up other projects first. I have all of the information I need so it is just a matter of test fitting peices and finalizing the drawings. Once I get back on it I should be done within a couple of weeks.
BTW and I already said so, that dyno looks great. I knew it would work out well.

Unichip Vs my CLS Dyno.
Since I have dyno for my 01 CLS with CAI/UR Pulleys and SR Headers, I decided to overlay the UniChip Dyno and mine. I normalized the Unichip Dyno scale to Acutal SAE WHP.
Here is the dyno:
Here is my orginal dyno:
As you can note, my Dyno is 100% match to the Unichip Dyno curve up to 5750 rpms where the Unichip start gaining more torque. After 5750 rpms my Torque curve starts falling and matches mattg curve with no UniChip. There is a good 9 to 18 lbft of torque gained by the UniChip.
I hope this info is helpfull.

BTW, As I mentioned before here http://www.acura-cl.com/forums/showthread.php?t=142985
The Unichip is leaning the Air Fuel after 5000 rpms! In the above thread as well as the dyno graph's A/F ratio, there is rich mix after 5000 rpms.

Yes but every car and every dyno is different. I wouldn't be surprised to see your hp numbers vary +/- 5 from Matt's

IMHO, 195 to 200 lbft is the max SAE wheel torque that you can expect from a NA 01 CLS engine. Unichip is extending the torque curve all the way to 6500 rpms instead of 5750 rpms.
Lighter wheels will help, port and polishing, bigger throtle body and Thermostat mod of course will help!
The only wild card... is the elusive RES!

i wonder what that combo will put down.

Close to 300whp all motor would be my guess. The built tranny wouldn't eat up as much power.

Matt, putting a 2nd on your new house anytime soon...
Anyway, looks great man! I'll call you for the track on Saturday. My S is going in for Aftercooler install this Tuesday.
I might run it if all is well.

Good luck at the track, hope to see 12's
BTW: When you are running nitrous the ambient temperature doesn't really matter. As long as your bottle pressue is up, you will run the same in 90 degree temperature as you do in 50 degree.

If you add say 60 WHP though spray you net 300+ WHP. But now with inclement weather you are only making 220 WHP. That 60 WHP adder only nets you 280 WHP.
The difference is that the power adder, nitrous in this case, normally gives the same power increases regardless of conditions. However, the base power will change with changes in weather conditions. This lowers the overall power change percentages but it does still change.

the event on saturday is a sport compact drag racing series, which means bracket eliminations. i'll only spray on the warm up runs and after i'm eliminated (unless i win ). the rest of the time i'll be running n/a.
