Are the OBDI and OBDI redlines the same?

I have a OBDII ECU and the fuel cutoff it around 7050 (according to the S-AFC).
My tach actually shows 7200 but the tach is off a little bit.

 

Umm...anyone???

 

6800rpm

 

redline is 6800 on obd2 motors...but i feel power a little over 7000

 

Is OBDI the same or different?

 

You need to specify what you're talking about. Redline and fuel cutoff are not the same, so don't use them interchangably, that'll only confuse people. Redline is what it says on your tachometer, but fuel cut off is the real "redline", the point you cannot pass. My dad's Prelude has redline at 7600rpm I believe, but you can pull it close to 8 before the computer cuts in. Similar thing with Celica GT-S's. Redline is 7800rpm, but you can take it up to 8300rpm in each gear before hitting fuel cut off. Also, the most accurate way to measure this sort of thing is with an AFC. The tach on your car isn't very precise, not to mention its hard to tell where exactly the fuel cutoff comes in, I mean who is staring at their tach intently while flying down the road?

 

My redline is like all other LS's 6800 RPM

But my Rev Limiter is at around 7300-7400 RPM

Is that what your talking about??

 

Yea sorry for the confusing question.

What I really wanna know is the fuel cutoff..not what the tach shows as the redline.
Thanx

 

My fuel cut off on my 95 LS is 7500 tac has 6800rpm cut off
