10,000 mi. the magic number??

[esmith13]

I just recently went over 10,000 mi. on my ep and I may be crazy, but I noticed some changes...

1. The car seems to have more pickup, like there's some extra horsies hiding somewhere that have come out to play...

2. The car seems more happy with a low RMP launch (under 1500). It used to bog a little like it was gonna stall, now it feels like the car has shed 600 pounds...

3. Acceleration seems snappier -- once again like the car has shed 600 lbs...

Not that I'm complaining, but what's up with that?!?

Am I crazy?.. or does the ECU hold a little back 'till that first 'official' Maint. cycle???

For the record, I've had two oil changes already , and now at 10,000 I am due for my scheduled Maint. (third oil change and tire rotation) WHICH HAS NOT BEEN DONE YET - so my dash still says MAINT. REQ'D.

The tempature here has not varied more than 5 degrees on average than in the dead of summer...

My last performance mod was a Typhoon SRI -- two months ago...

Please, someone tell me if I'm crazy or not - and if not, why has my ep decided to make me a happier camper all of a sudden????

Thanks in advance, sorry for the lenghty post...

Dude,

I know what you mean. I have over 10g's on my odometer and yes, the engine is a little more livelier.

Side note, if you are doing your own maintenance or getting it done at Jiffy Lube and your Maintenance light comes on, we can reset it ourselves. It tell you how in our owners manual. I've got three oil changes in my ride.

[hacim]

Hondas have been known to do that. They are finaly breaking in and the motor loosens up a little and it gains some power. Hondas are just funny like that, wait til you have 30,000 miles on it.

[ApexinSi]

I changed my oil at 5k and at 10k...why does everyone keep changing their oil so many more times?..the manual says every 5k and 10k is service + oil change...I'm lost. HONDAMAN please clarify this for me.

2. The car seems more happy with a low RMP launch (under 1500). It used to bog a little like it was gonna stall, now it feels like the car has shed 600 pounds...

This may be a long shot..

have you recently lost 600lbs?

:D

[esmith13]

ApexinSi,

Although break-in is over, it is still very likely that your engin is wearing itself in (as apposed to wearing out). That means little metal filings are floating around in your oil that may even be too small for your oil filter to catch. An oil change cleans these filings out before they build up somewhere and clog up or coat a lining that is precisely sized with little room for error.

That and Minake (sp) says your engine will thank you for it... :D


02-sir,

Although my weight may one day be the reason I loose a race (I weigh in at 240 lbs. @ 5'11") I have no chance in hell of being richard simmons greatest dream come true...
...Thanks for checking tho... :D

[02-sir]

just checking!

(I go 2 1/4 myself, maybe we can start an overweight EP driver section)

[HondaMan]

Yeah, I remember my '89 Si getting better with age (like a fine wine). :)

[dannysi]

I have 10,233 miles on mine and now I am really enjoying the car.

[CleanBlackSi02]

Daytime driving in the heat has gotten much peppier for me at 8,500 miles.

[natesi]

I've got almost 1,000 on mine (9000 less than you guys), but I've noticed the clutch thing already. I actually made a post about taking off in this car becuase it just seemed to not like taking off below 1500 RPMs at first. I found that strange, since in my last car I could get it to take off at like 800-1000 RPMs. Now the Si is a lot better though. I'm sure part of it is I'm more use to the car too... But honestly, it can't all be that. I'm sure the engine/cutch is behaving different too.

[nickw252]

Damn you people are lucky, I gotta take my 00 Si to about 3.000 rpms for a launch.......

I don't think they were talking about launching, rather everyday driving. I launch at 2800-3000 rpms too.

[civic hatch boi]

i launch at 6500.. no wheel hop or spin. just take off..

[sonic imperial]

To you guys that are launching at 3000+ RPMS, do you ride the clutch out slowly or do you just pop it straight out? Also, are you driving like this at every take off or just occasionally?

[civic hatch boi]

i was joking. i launch at like 3k. and i drop the clutch. i get a good amount of wheel spin tho

Even at 3000 rpms I can't just drop out the clutch....gotta feather it or else I don't have any traction.

Funny i should read this, I read this reply to one of my post's the other day see if this story has any girth to it

Let me say my peace on this.

The ECU on the K20A3 holds the car back and lets off slightly at certain mileage intervals. Anyone who raced a K20 that was new or under 2000 miles ran a high 7's 0-60 low 16's 1/4 mile car. At around 4000 miles the ECU lets off again and the car will run an average 7.6 0-60 and 15.8 1/4 mile.
The final ECU change is at 10,000 miles and a few more tenths are dropped making the car a 7.4 0-60 and a 15.5 1/4 mile.

There are 2 really good articles in the latest honda tuning about a famous Honda ECU programmer that just cracked the K20. There is more data in the K20 ECU in the fuel mappings alone than in the entire B16 ECU.

I can't remember the programmers name because I'm at work and I don't have the article with me. Needless to say there are quite a few people out there that are in for a really big suprise.

I'm at the 5k mark and the vehicle is Dr. jeckel and Mr. Hyde.
The car was so damn slow up to 2000 miles that I almost sold it.

Word out there in the ECU programming world is that Honda's new ECU is loaded with all kinds of trick maps that change as the car gets older etc...

The K20 has a few tricks up it's sleeve just wait.

Guess we will find out eventualy

[civic hatch boi]

sniper good stuff!

[civic hatch boi]

wait. dont' all cars get faster as they rake up more miles.. also.. 16 to a 15.8 isn't that much quicker.. im thinking that won't even be a noticable gain in power.. neither wil it be at 10k.. geez .now that i think about it... just got my hopes up :(

Here is the article on the k20 and ECU , ect ect. Very interesting.

[BlasTech]

Im not an expert, but I remember reading (somewhere on http://asia.vtec.net/beystock/tuning.html) about INJECTORS coming with some protective wax (for storage and transit before they are put in) that slowly wears away, allowing the full amount of fuel to get through after a certain amount of time.

The tuners in the article used a bath and supersonic vibrations to wash the injectors on a newer car, speeding up the injector "breaking in" process, and showed some gains.

Maybe this could be a part of it.

The article you linked says nothing about this. As much as i'd like this info to be true I'd still like to see some reliable sources. Thanks.
