i was driving home today and a friend (in his civic) was behind me so i was messing with him. any way i accidentally hit 8 grand in first ( i usually shift a 7000 if i'm at wot). well my question is what should the revlimiter be set on? i thought it was 7600. i know the car was stock when i bought it so i know it isn't chipped. am i just wrong about the revlimiter setting?

 

the red line is 7200 on stock computers rev limitier kicks in around 8000. your tach could be off a little

how do i test this?

 

a digital tach

 

I accidentally hit 8000 RPM in my '01 'lude in second gear, and that was when the rev limiter kicked in. The engine just shut off for a brief moment before it fires back up.

BTW, hitting the rev limiter is not good for the engine.

i didn't hit the revlimiter thats why i asked, thanks for the advice though

 

I got a p28 with hondata, and have the rev limiter set @ 8200. I have frequently hit 8K and havent had a problem

(going to the track tonight to see if the hondata helped much )

Now, I've got a question to ask: Is there any benefit in shifting above the indicated 7400 RPM (on stock tach)? The HP and torque both drop after the power peak around 7000, so keeping the engine reving to 8000.... I don't know. Is it becuz after the upshift you will still remain in VTEC??? When I shift around 7400, the RPM drops to around 5000. So I guess if you shift at 7900 to 8000, the RPM will drop to 5500 RPM after the shift? Correct me if I am wrong...

You should shift when the needle gets somewhere around 7600-700rpm.
93preludevtec when it shows the needle hit 8k, your tach is actually off a bit. I used to wonder how come when I was in 1st and could still shift when the needle showed around 7700. I just got my VAFC installed and the tach is moving just a little faster by about 150-200rpm.

 

The stock tach is off a good bit in the higher end. Your fuel cut is at 7600, which is 8000 indicated on the tach. The H22 makes power up high, but it does drop off before it hits fuel cut. But if you shift at exactly 8000, it will drop you back into your power band, and it makes it easier to stay in VTEC in the first few gears. SO...yes, shifting at 8k will give you better times, and it won't hurt as long as you don't do it too often.

 

In reference to how much the the stock tach is off, its 200 rpms, like if it says 8, its really at 7800. This is what my car read out when i put in the VAFC.

 

ya my v-afc reads lower also...good times

 

Along the same sort of lines, if the engine is cold is the rev limiter adjusted to a lower RPM. Say around 6500 to protect the engine?? Or is there something wrong with my lude (It's definitely not a common thing for me to hit VTEC when it's cold..)

you can't hit VTEC when it's cold because you have to have the right oil pressure for the VTEC to engage.

 

Great. Thanks for that. It's hard to find anyone around here that knows much about the VTEC Ludes and i've only had mine about 2 months and trying to learn about it.

BTW... its NOT good to go fast when your engine isnt fully warmed up. Try to stay under 3500rpm till its warmed up

 

ok, first off you can make power beyond the 6800 or so, especially if your switching computers, hell a year ago i made power all the way to 7500 rpms....it depends on your ecu too...the stock p13 stops making power, but if your using hondata or a p28 chipped ect, your going to be able to have more agressive feul maps in the higher RPMS, and your stock valvetrain will handle 8k shifts...and to whoever said hitting the rev limiter is bad for your car, its not..later
