installed the chip last night -pretty straight forward
fuel light was illuminated so added 2 gallons 100 octane
took her out this morning before it got to hot o.a.t. was 86f.
first 3-runs with the g-meter were in map b the car pinged
like a bitch the fist run, the next 2- no pinging but on all three
runs it would fell on it's face right off the line, times were 14.7-14.9
which is about were it was a couple weeks ago at 105 oat on 91octane.
shut the car down for 5 mins between each run.kinda bummed, so switched
to map a, the car ran awesome, barked the tires going into second which it has
not done since I put on the es100's no bogging and ran a 13.95 @107
now I start to smile! the accellerometer showed 110HP pre chip and 140HP-post
not sure why those are so low got's to learn a little more on how they calculate HP
it looks like map b is to aggressive for my car even with 100 oct-

 

Is your mod list up to date? 13.95 seems very quick for your bolt ons. Also, 107mph doesn't jive with that E/T for a CL-S. How accurate is that G-meter?

 

up to date besides intake don't really know how accurate it is.it seems very
consitent-and have been told they are usually within a couple of tenth give or take.

 

at the 14.7 i think it was showing 96ish on mph the
13.95 it showed 60@2.3 1/8 9.27,1000@11.82 didn't
note the other intervals on the14.7+ runs

 

Why are you running 100 octane??? No need for it on a N/A engine.

 

The UniChip has a "B" setting for a higher octane.. "A" setting is for a normal increased performance on our regular gas..

 

more testing is needed!

 

I wish they had something for the RSX. Hondata is out but I cant go a week without my car

 

It has been tested and is now being tested by all of us that were in the Group Buy.. We'll let everyone know how it goes..

 

ref: hp numbers i didn't enter in my cars weight
so was measuring off a lighter car but definately measured
an increase from pre and post chip

 

Gtech pro?

And, just to be clear. Could you provide the mods on the car?

And, then provide you general area you are running (State, town)?

And, are you saying that you went from 14.7 to 13.95 by only adding octane + mapX + e-manage?

 

This is bullshit. Besides me, the only dyno done is at Uni-Chip and they could easily doctor their numbers to fake the results. I might be taking them up on thier "90 day guarantee". I didn't pay $600 to lose HP. Bullshit.

 

Nah that actually sounds about right. He has intake, headers, exhaust, and Volk wheels which I'm assuming are fairly light. Many people have run 14.1's and 14.2's with similiar mods including myself, so 13.9 sounds good. But not in those temps. Somethings wrong there .. What did you run before the chip on that gtech?

Jet tek .. have you ever run the car at a real track? if so, what were the ETs?

EDIT: Oh and theres no way you trapped 107 with those mods. I'd believe MAYBE 99.x, with a tail wind on an amazing day 100.x

 

Yeah but 107 mph is extremely fast. He shouldn't be any faster than 101 mph. 107 is close to 300 whp. No chance he is pulling that at 13.9 and with the mods he has.

 

Post some real time slips. Gtech means nothing and 107mph is not even close.

 

no way your trapping 107

g tech blows go to the track

 

actually it' a belltronics vector-f1
really can't say what actual .25 times
are because i haven't had it at the track
just trying to verify a pre and post gain
2 weeks ago it was 105 at about 1in the
afternoon so probally closer to 140f off the
pavement 14.7 was the best i could get
this morning it was 86 and early enough were
it was not any road heat 14.7 was the best
i could get in map b so i would have to say if anything
it lost performance map a was the 13.95 run
i cant say if it acturate but like i said it does seem
to measure pretty consitent, also the other week when
i ran it was no power braking today all runs were power braked
wasn't sure if the g-meter would sense an early start
but didn't today when i did it
just trying to put some info out not claiming how fast my car is

 

First, 14.7 at 105 degrees is so off the chart, that I would consider the unit to be basically useless for absolute readings.

And, I’m also having a hard time picking out exactly what your saying.

Well, unfortunately, 107 in the quarter is so far off for the components and temps, that I'd pretty much guess that the instrumentation is not going to be too useful for extracting real numbers. Your unit doesn’t have an accelerometer to correct for pitch errors. As a result, there is a ton of places that will generally result in over optimistic readings. It will even give you too-high readings going uphill! The errors are compounded by higher speeds. The car's front tends to pitch up more and more with increased speed, and this makes the "device" include the normal force of gravity into its calculation.

Others around here with I/H and light wheels and tires have run a best of 14.1 - 14.2 at 60-70 degrees (or colder) at sea level. The times running at 80- to 100-degrees F get pretty slow with that setup.

The 14.1 and 14.2s were close to 100 MPH at the end of the quarter mile.

107 MPH is so off the map, especially considering the weather that, you should forget about those numbers. Really, I know what I’m talking about.

To give you a little bit more information about what's happening:

When you start off, the force of gravity (what holds you down to the earth) gets summed in to the unit's when the car transfers weight. That doesn't mess-up the top end speed figures as much as one would expect (although if the car is really bucking the 1/4 mile will be overly low and the MPH will be high). At the end of the run, the CLS typically has the “nose up” due to the lift. The accelerometer adds in the pitch angle of gravity (1G) and this is SO MUCH HIGHER than the forward acceleration at the end of the run, that even a few degrees of pitch will cause an end of run figure to be way out of wack. (I’ve done some calculations, and it isn’t pretty.)

The Gtech Competition at least has pitch compensation, but it only works well on dead smooth roads. The regular unit already has a hard enough time working to 60 MPH, and can be a bit optimistic when it does 1/4 mile readings. The traps can run 5- to 7-MPH high.

Here is the part that should concern you and is from the Beltronics manual:

The 2-axis sensing is for-aft and right-left. IOW, it doesn’t have an extra accelerometer pointing down. So, when the car is not on a level road, or the car pitches up or down due to acceleration (weight transfer), and aerodynamic lift, you get completely bogus results. If you could weld the springs shut with bars and get out a level to insure the road was flat as glass, it might be ok drag some numbers out again. I’m sorry, but it will give you relative numbers to compare against, if and only if you use the same road for every trial. And if there are any bumps, dips, or the slightest elevation changes, it will misrepresent the data.

Sorry, but you're going to need to drag that puppy off to a track one day when it isn't too hot to get a solid reading.


-- feel free to disagree. I even use the Gtech for readings, but I generally knock .2 to .3 off my 0..60s to compensate for the pitch. The Gtech Competition unit at least compensates for pitch error on dead flat roads. IMO, the Beltronics unit is basically useless for “absolute readings.” A “top notch” unit would have 3-accelerometers and 3-rate sensors.

 

am i reading that right 13.95 without headers?

 

_________________

Dont know about u... my 01 CLS had more than just lightweight rims+good rubber + header+intake+exahaust and i still couldnt get anythhing below 14.4....

i dont know much about the chip but from 14.7 - 13.9? u need A LOT OF HP to drop .8 secs...

 

I've got rubber/I/H/E and run sub 14.4s all the time. I'm usually right at the 14.2-.300 mark. I'm pretty consistant; I should bracket race. To drop .8 seconds you'd need about 40-50 additional whp or just a very good launch. If I had lightweight wheels and could pull off a 2.0 60' instead of the 2.1s that I regularly do I could have dropped .8 by now. So far I/H/E has dropped me .6 from the stock time of 14.8.

oh and

 

I had exactly what you just stated and was able to do a 14.17 @ 98.5mph, 2.17 60ft. Many other members were able to get times lower than mine with same mods or just a tad over.

 

I GUESS East coast CLS are faster than west coast?

 

East coast wednesday cars

BTW guys .. I've been driving my car alot today. took it on the first long drive with unichip. I don't know about the rest of your guys but I am POSITIVE I feel a difference, its not just in my head. 3 friends who also spend alot of time in my car were in it through the course of the day and could also feel a difference. MUCH more responsive throttle, low end torque is much more abundant, and top end VTEC is definetly improved with an extra pull right at the top end before redline. Car just feels stronger all around.

Car went 65-110mph on the parkway like it never has before.

 

ahem

 

N/A that is Matt.

HAHA

ahem...

 

he went pretty quick N\A too tho.

 

Did you use the *same* strip of road for each run?

Gtech readings will not be accurate to compare unless you run the same stretch of road every time. And running down it the same way everytime, i.e same direction. same starting point.

Lots of people use the gtech wrong. Comparing GTECH runs for different roads is not going to be accurate at all.

Also need to use a GPS meter and watch the elevation on the strip of road you use. Make sure the elevation doesn't change on it. The stretch of road needs to be flat. i.e. no changes in elevation on the GPS.

 

I've ran a GTECH at the strip, the MPH on it was off but the times were accurate

 

^^
the gtech can prolly get your mph as you cross the line but not the actual trap

 

Bottles are for teh babies.

 

Did you use the *same* strip of road for each run?
yes but i was doing up and back didn't really effect
times which way i ran it -visually the road looks flat
haven't driven it much this weekend but seems like
it might pull a little harder from a cruise to accellerating.
no cel light yet anyway!

 

The Gtech give a reading that is calc’d based on the exact moment that its computer thinks the quarter mile is reached; this is going to be higher than the track’s end-or-run average.

Depending on the Gtech model, the car, and how bumpy the track is, the Gtech can read 5+ MPH above the actual end-of-quarter-mile speed. If the meter were perfect, the difference between the track’s averaged result would be around 2 MPH (it would vary on speed, acceleration, etc.) So, add in a possible 5+ MPH if the car has some front-to-rear lift differential (it only needs to be a few degrees of pitch, and one of the members was nice enough to show the CLS with its front end pitched up at higher speeds).

 

isnt the trap average of the last 66 feet of the track??

 

Yep!



66-feet between the MPH and ET (as shown in pics) from:

Very interesting Eric! Something I did not know!
