well i put my vafc on a cuple days ago and when i got to 7500 on the cluster it hits rev limit but the vafc is showing me that it went to 8500 if correct how do i go about fixing the cluster to match the vafc

 

the vafc is prbably the one that is off. you probably didnt install it right.. check something out.

 

im sure i did it right i double check everything and i was trying to find out what was the problem when i did my swap but i think it was my cluster not reading right cuz im running a skunk2 program and i tried another ecu and it would not let me go past 7500 and it was a p30

 

id definitely believe the VAFC over the stock cluster
stock clusters are always going off

I believe you are far from right. I have some software of my laptop where I can go in and watch all of my sensors from my OBDII port, and the stock tachis off anywhere from 3-600rpms at any given time.

 

thats what i thought so im trying to fix the cluster. it seems like the cluster is seting the redline there cuz the cluster is correct until vtec seems like it slows down to make redline 7500 any one have a problem like this before

 

make sure you have all the settings on the VAFC right. When I did my swap, I reset the VAFC and it set it to defult as a 6 cylinder. Yea, my RPMS were just a tad off.

My stock tach sucks. When I had the d16z6 in my car, my cluster said I was shifting at redline (7200) but my VAFC said 69xx. The stocker is defently not ment for presision.

 

yea i did all of it right i went to settings and set the cylinders and all correct every thing works correct just need to get the cluster to work right anyone else?

 

the stock tach is off, u can pull the needle off and reposition it. my vafc2 reading compare to my SiR cluster, the cluster is off bout 500 rpms, so i pull the needle off and reposition it keepin a steady rpm reading.

 

My Vafc reads 1k at idle while my tach says 17k

Dude your tach reads 17000??? j/k i know what you mean. lol

Anyways the stock tach are stupid. It's way off. I don't even trust it. I trust my 5" tach more. The 5" tach and my vafc is all i pay attention to as for rpm.

actually it is probably the opposite of what you just said.

Stock tachs read higher than the actual engine speed. Reduces your chance of over-revving.

Is it that far off at other points? For me it's about 100 rpms off at idle, and about 2-300 off in high rpms...

 

werd... my stock tach reads 1200 at idle, 6000 at x-over, 9000 at rev limit.... all those values are 500rpm too high (chipped p28 with stock p30 program)

 

yea but something is realy wrong cuz mine is a whole 1000 off on rpm and it bounces as if 7500 is limter and it reads 8500 on the vafc
