Not at all
. Beauty of a two-way forum discussion.

But then since this was about dynoing a stock civic I thought your Civic could be putting out more than the graph's depiction.

130 BHP stock - 10% drivetrain losses = 117 BHP. Its in line with expectations.

True. No point comparing a dyno run of an India-spec car to a Euro.

Just a note : The remapp'ed Civic graph posted earlier isn't m4ugr8's car.

Of course. The Automech exhaust has already been fitted on my car and I'm immensely happy with low end throttle response. His quality of install, as always, is impeccable. No headers possible, so don't expect too high a gain. Will dyno sometime next week and update.

That would be awesome! I feel 2 times with a difference of 60 days would be ok too. Save the extra amount for petrol. You will need it when you redline it all day... |
Aye aye, well said & noted.

Could be. For example, a free flow exhaust should theoretically improve the exhaling capability of your engine and hence, the FE too. However, its IMPOSSIBLE to drive with a light foot. You get addicted to the sound, and keep revving again & again

On the face of it, I'm not impressed at all with the remap. Perhaps a before / after would be most indicative, but that's not been provided to us.
We didn't have a dyno back then, but the way that the Petes box performed was for all to see. We timed Rtech's Octavia in a 0 - 100, fitted the box and timed her right after on the same day. There was an improvement of nearly 3 seconds IIRC.

I'm told that remaps on Civics aren't exactly hot. They mainly increase the revv-limiter and if you get a BHP gain, its too negligible to mention.

I may add that has someone tried the standard European map which is 140bhp as against the 130 horses available to us. With 91RON standard across the country (unofficial additives excepted) we should be able to run it. I remember a post somewhere that a person had that map installed and was quite happy with it. This was a long time ago so cannot remember where!

Great suggestion! How would we get Honda's original 140 BHP factory map? That would be the most ideal situation here!

Yup, rightly said, I'm a huge fan of factory horsepower. And that's got a lot to do with the shoddy modification work you get at most places in Bombay. I've seen way too many perfect cars end up as unreliable pieces of junk post major modifications.
That said, the Civic has huge bolt-on modification support. If (and ONLY IF) I am convinced about the quality of a bolt-on blower, and find the right guy to install it (most probably, down south), I *might* take the plunge. Would need to be really assured of the quality before I do. Reliability is of paramount importance to me (the car being a daily driver + tight schedule).

Is Kiirus any good? Know anyone who's gotten cars tuned by him? Anyways, I hope we have some first-hand forum experiences soon.

Viper, people on the forum have claimed (and keep claiming even today) major improvements even after getting a stock replacement K&N filter. I wouldn't go by MHP (mental horse power) claims to pass judgement on a remap.

My Car has become very responsive and the Joy to REV a Honda engine has increased three times. The new RPM limiter is now 7800 and the car goes all the way to 7800 without any problems, It loves to go to that point.

Nice. I am myself keen on increasing the revv limit. Honda's 7,000 cut is way too conservative for this engine. Atleast 7,500 rpms.

Note that the torque on the dyno graph is displayed in lb-ft. Convert to NM of torque (which is what Honda has used), and you're looking at about 150 NM.
