There was a post on here long back by a guy who had both the 194bhp and 197bhp maps done on various 2.2 civics, with R/R results posted. Probs best do a search

 

they werent independently done im sure! happy to be proven wrong though!!

 

As coste1l says all results i have found have been done at Celtic

 

A rolling road can be shown to show any result you like, depends on how it's calibrated. They can only be trusted to show a difference between before and after, therefore regardless to whether it was independant if you get a before reading and then an after and the RR is set to the same calibration all is good.

 

by changing the ambient temp and stuff? i wondered about that myself

 

It was me that had the standard map on my previous 06' Civic and the 197 bhp remap done on Celtics RR on my current car. Here is the thread http://www.civinfo.com/forum/engine...s-and-transmission/28838-celtic-tuning-custom-remap.html?highlight=celtic+remap

I had my 06' Civic independently rolling roaded at Power Engineering in Uxbridge. It came out at 192 bhp.

I have no doubt that Celtic Tunings claimed power outputs are very accurate. Obviously, no two cars are exactly the same as standard. Furthermore, as previously pointed out, no two rolling roads are the same.

Celtics Dastec rolling road in Cornwall is one of the most modern and accurate rolling roads in the country.

i had my civic remapped @ p-torque a few weeks back and they also did a rolling road before and after,

standard my car was bang on 150bhp and after the remap it was 180.2bhp

 

30 bhp gain sounds about right to me

 

one thing i would say is, the pull and acceleration in 4th gear is stunning, its dose around 90/94mph in 4th gear, coming off slips roads and onto the motorwway has never been so fun!

Seems low to me. Mine hits the rev limiter at 85 mph in 3rd. Haven't been to the rev limiter in 4th as i don't want to lose my licence!

Steve

 

the speed in each gear is governed by the gearing and wont change how quickly it gets there......

 

well it got like **** of a shovel and feels fast lol

 

thats what its all about man!

 

85? in third? do you mean 4th? mine will do 70 in 3rd standard and a remap cant change gear ratios

 

Errrr NO I don't mean 4th gear, otherwise I would have said 4th gear! I've been driving long enough to know the difference, believe it or not.

Sounds like something's wrong with your motor to me.

Steve

 

Mine can hit 100mph (on the speedo at least) in 4th - I'd imagine?!

 

what about in 3rd?

 

not sure.

 

great gains from a diesel..ill have to get meself one soon

 

if you look at the rpm for the gear change you will see that there isnt much left to go but from the same thread the standard 2.2 at just before the limiter in 3rd now unless you change the box how can you go any faster in the same gear??

 

By taking the revs from the 1st gear change point (not the rev limiter) of 4670 and and multiplying by the mph per revolution in 3rd gear gives you 81 mph. Not sure at what revs the limiter cuts in at so can't give you the exact figure.

 

Just found this http://www.civinfo.com/forum/engines-and-transmission/12759-rev-limiter.html thread that suggests the rev limiter does not come in till over 5000 RPM. At 5000 RPM with the gearing off the info you have attached would equate to 87 MPH in 3rd gear, and if, as one person on the thread suggests that the limiter is actually set at 5500 RPM that would equate to over 90 MPH in 3rd gear.

 

gentlemen i humbly apologise my car will achieve 85mph in 3rd gear and may have actually gone further but mechanical sympathy prevented it. It certainly isnt the best way to drive it to achieve maximum acceleration but it is possible. im now going to bake a custard pie for my face...........

 

Humble pie tastes better! Did you go to Germany this morning to find out?

Rocks back and forth in chair repeatedly muttering to self!

 

errrrr yes of course

 

relic if im working it out right the car will do 174mph at 5k in 6th?? im sure its not that simple

 

YES

 

So for arguments sake, theoretical speed at 4,500rpm in 6th is 155mph!!! if there was enough BHP...........

The figures give you an opportunity to check RPM vs MPH.
See what the RPM says you actually are doing...
..compare to what the speedo kids you, that you are doing
