Was driving my girls SI today and was beating it up and down the streets. I noticed that the redline on the gauge itself is at 8k. When i was messing around i noticed it went passed the redline mark and the rev limiter was set close to 9k. Seemed to be 8.8k actually.

Anyone know what the normal redline is etc?
Also
When vtec engages it is at 6.5k for butterflies and 6.7k for full engagement.

(those numbers might be off some, but it seems to be totally different than my gsr)

Basically is that how the SI comes stock or is it a different ecu?

 

nobody?

 

Normal redline should be 8200 RPM, but its quite normal for the rev limiter to be a ways beyond that, doesn't mean its a good idea to go past the redline though. The Si doesn't have secondary butterflies either, the only B-series that does is the B18c1 in the GS-R.

--- Why would the limiter be at 9k? and vtec at 6.7k? my friend said that the ctr ecu are those specs.

 

rev limiter at 9 grand sounds normal enough, but vtec is definatly sounds like its engaging kinda high. around 5300 RPM would be normal in my opinion.

Actually look at that. That's exactly how my si is. They are even talking about ctr ecu etc. States in the title it is a full CTR swap.

but that's when my vtec engages and the rev limiter.

 

So basically you're argueing because you think a ctr ecu is cool? why is that i really would like to hear your reasoning.. because it sounds to me like you really hope you have a ctr ecu... I'll tell you how you can find out but the odds that someone put actr ecu in a stock si with a b16 are pretty rediculous..

Go to an auto parts store they let u use their scan tools for free.. use one and see if it can connect to your car... if it can.. your ecu is usdm! if it cannot.. your ecu is jdm and most likely is a ctr ecu if you are hiting vtech.. or read the code on the ecu ... but you sound too lazy to do this so...

lets pretend for a moment that you do have ctr ecu... thats awesome you just lost a bunch of hp and thats super cool... why? because a ctr is a b16b with more compression then your engine, better cams, a better flowing head which means more air, and basically just a destroked b18... so why you want or hope u have a ctr ecu is beyond me... but if you do awesome you are now slower then you would be with a stock ecu! SUPER COOL

 

im guessing or would bet 100$ that its a stock si ecu and your tachometer is off (like all hondas)

and you probably have no idea what you're talking about anyways... the butterflies kick in at 6700? LOL good times omfg

i have the ctr swap in my red civic. the redline is set at 8800 but can be chipped to 9200. and you can chip your vtech to engage at whatever you like. normally 4800 to 5600. stock is usually set about 5200-5300.

--- Idk what your problem is, but you seem pretty hostile in that message of yours. I didn't once say i was "cool" or anything on that line. I am trying to figure out why the hell the car is so different. I am going out soon to check the ecu code. The car when i bought it to build for her had a blown jdm b16 swap and no interior. I put a new motor in it and the interior, never bothered to check ECU. But yeah, watch your epeen cause it's kinda annoying when im asking a legit question and trying to find out some information on the car and why it's acting the way it is.

I was watching other videos and all other SI's were 8.2k rev limit and 5.3-5.7k vtec engagement. So please settle down and instead of getting all epeen crazy. Just don't post next time.

 

oh and by the way the ctr ecu with an actual ctr swap is a us honda killer. i ran an h23 frankenstein in one civc and dynoed 225whp( with a few mods) my ctr swap last read 325whp. ( with a few mods). there isn't a us b16 out their that will outrun a jdm b16. specially a b16b with R4 lsd tranny. it is the way to go.

 

Alright, no need to flame this guy that bad. I agree with you though, I think this guy hopes he has a CTR ecu, now how a CTR ecu would end up in an Si is beyond me. And yes it wont run right if you have a CTR ecu on that engine.

 

he said the car had a jdm swap in it. the previous owner or "swapper" could have switched it. but he sure spent some ching for that ecu. if it is a real jdm ctr ecu. i know what i spent on mine.

 

Hang on, the car had a blown JDM B16 swap? Why? The car came stock with a B16 in it from the factory, who in their right mind would swap out one B16 for another, expecially when the cost of the Si is so high to begin with, it just doesn't add up, even if it were a B16B its still not really worth swapping in a car that already had a B16, unless that engine got catastrophically anhilated somehow.

 

true. but what happens when you let a young punk drive a civic with a B16 in it. they race. and a lot of these guys don't kow what they are dong when they race. they grind trannies, blow motors, and lock engines. so now if you were a dumb punk and you blow you usdm b16 what do you do. you spend mom and dads money to get a jdm swap. and look what happened. they blew tha one too. i see it all the time. i was a mechanic for 6 years. now i only work on my own cars. i have learned to take care of mine by watching others destroy theirs.

lol i wasnt trying to flame im just saying firstly-- yes a b16b running a ctr ecu would run it how it was supposed to run from the factory.. no one argued with that.. What i am saying is if it is a B16A or any variation OTHER THEN a B16B then it is NOT going to run right, just as 94EG8 (Who obviously is one of the few who know what they are talking about) Has agreed with me on...

If the ecu is Chipped as... someone stated.. then you are running obd1 .. so my recomendation to hook a scan tool up to it would prove correct as well... GET A SCAN TOOL it will tell you if it is a stock ecu.. obviously the EASIEST way to check is to pull the ecu out and read the 3 letters on it.. IE: P28 if its a chipped obd1 ecu... i had an ITR ecu that was obd2a and it ran my lsvtec swap but not flawlessly and my lsvtec swap was pretty close to a stock integra type r.. the best ecu for your engine if it is stock is the one that came with it from the factory.. Vtec engaging at a point other then what the cam was designed for (later or earlier) is pointless... a stock b16 hits vtec at like 5500 (b16a2 from a 99 00' si) I believe.. or somewhere around there 5800? so moving that point with stock cams is completely non beneficial... i suggest you get a stock ecu if the one in there is not stock (if you are running a stock engine..) just pull the ecu out? what are you waiting for???

 

actually i am running a true ctr ecu, customized by hondata corp. for my complete guts upgrade i had done before i had the ctr swap sent here from japan. believe, i know exactly what i am talking about. but i too agree with you that he should run a stock ecu if he has put in a us b16 engine.

not arguing that at all.

Was one of those mods a turbo, supercharger, or nitrous? Because that's the only way you're getting 325 HP down to the ground out of a B16.

 

i wasn't saying you did not know what you were talking about.. its people that post about things they have no idea what they are talking about and try and make it sound all confusing that get me mad.. its bs its like look if you have a question.. ASK but listen and pay attention.. so that you can take some CORRECT knowledge away from this forum.. rather then go around talking about secondary butterflies opening in a b16 when a gsr intake manifold wouldn't even fit on a b16/itr head :/


LMFAO seriously what is the record for whp from a b16 n/a anyways? i know even with like a dart block and sleeves etc.. your pushing it at over 300 hopefully ur talking forced induction of some kind

 

complete internal upgrade before shippig here. port and polish, electric water pump...........etc. i can't give it all away just yet.

No way in hell you DOUBLED the power output of a naturally aspirated engine without forced induction. If so, you need to post in the All Motor forum and assume your GOD STATUS.

lmfao +1

 

ok. like you i just put my 2 cents in to help this guy out. i have no idea what the record whp is for a b16, but i can tell you i have seen one running all motor over 500. i almost ****. but it was true.

 

DUDE WTF this is the bs i was talking about. I take back everything i said about you schafedawg... there is NO B16 PUTTING DOWN 500WHP ALL MOTOR

WTF why do you have to spread MISINFORMATION

 

say what you want. but do your homework. just because you haven't seen it yet, doesn't mean it isn't true. obviously you don't get into racing. autocross, drag, or anything. i saw a b16 in japan, LAST YEAR, running 500 all motor. i go there almost every year. i could care less what you think of me. i have enough friends i don't need anymore. my cars, racing, and background do my talking for me.
