Please, does any one know y my redline is set at 6700 instead of 8400??? It happened after i had the vafc installed, i have already unplugged it too. it happened b4 but i plugged in a friend's vafc and plugged mine back in and it changed the redline back to normal. now just yesterday my redline changed again.

 

It sounds like you are in limp mode or something. Do you have a check engine light?

 

....you wired it up wrong. vtec is disabled most likely.

When the ARRR is standing still, VTEC is disabled, and redline is around 8000 RPM. So, I wouldn't think it's a simple as that...

But good luck dude.

 

Check engine light? maybe ecu code 22. me and the people i know wit a vafc all get that problem with our Vafc. we call it Vtec 22. it changes the redline to about 6k well right before 7k.

yeah, i'm getting code 22. how do i fix that? and vtec still does work. but afteri go into vtec after like 70 miles an hour, redline will change to 6600 or around there until i turn the ignition off then back on again. and when i unhook the vafc the redline is at 6600 no matter what. any ideas on how to fix this?

 

maybe you fried the ecu...try and get a known good ecu and plug it in and see what happens.

 

Uhh-Ohh.......

 

i don't really know many people with AR's. so locating an ECU is gonna be difficult. but CWTegRNo.160 says him and his friends have the same problem so i don't think the ECU is fried.

think about that!
so he could burn up another one... not too smart.

If everyone would read this , it sounds like a loose wire.

I would sit there and go over every connection and make sure they are all tight. You did soder each one and tape up each one?

start with the basic ****,

 

I have no idea, i had a shop install it for me because i did not want to mess my ECU up. But i was watching him do it and all the wires are taped up after it was soldered.

If you want get under there and start working... look for a bad connection, loose wire or a mess up of some sort.

Or just wait til the shop opens and tell them to get a tow truck to pick up your car.

if he connected another ecu to the car without the vafc why would he fry it? if he did, then he is having other serious problems other then a low redline.

maybe he fried the original ecu when he was soldering into it with the vafc. from what he has said the car is still running with a low redline even with the vafc not connected...

 

Ugggh..
But why even take a chance of messing up another ecu, start with the basic **** and move on. to destroy more then one ecu is fine if you have money falling out of your *** hole but to me ECUs are pretty damm expensive.

Maybe the shop that did the install fried his ecu or maybe there is a short and the next ecu he plugs in it will be shorted when he makes a right turn... the point is no need for throwing money away.

 

that's just by disconecting the VAFC by the plug....but it's still wired into the ECU. i know that some wires had to be cut off completely that went to the ECU when the VAFC was installed, so i think it should work after the ECU is wired the way it came from the factory. The thing is, i went to a shop about 2 hours away in my hometown, and i won't be going back there till next week...and i don't want to spend more money at another shop...so if possible, i would just want to try nd fix it in the mean time.

since this guy had the same problem, i'll wait and see what he has to say.

this is obviously comming from someone who does not have all the info. again, why would he short out another ecu if he does not reconnect the vafc? as he has said he is still running a low redline even with the vafc NOT connected? so if he reconnected the ecu without the vafc what wires could be loose? nothing could be loose...the ecu uses pin connections.

what are you talking about? are you saying that 8 or 9 pin connection from the vafc to the major "bundle" of wires that actually get connected to the ecu?

Cause maybe the dumm *** who wired it up cut and spliced the wrong wire into the vafc harness, It's possible to damage w/o the vafc plugged in... it like touching two wrong wires together.

But like I said why risk damaging more things and wasting money, get under the dash and start looking- it could simply be a loose wire.

 

Get a Helms (for the wireing diagrams) and test the continuity between the ECU pins and the end of the harness where they spliced in the AFC. That will be the quickest way to find your loose/unconnected wire, which probably is the case.

 

ok...i just got done checking all the wires...they're all fine. i don't think it would have been a loose wire at all because when i turn the ignition off then back on with the VAFC plugged in, the redline returns to normal but the CEL is still on. then after after flooring the gas and redlining 3rd and higher, the redline goes to 6600 again, turn the ignition off nd on again, all is normal but with the CEL still on. i don't know if i'm making any sense but it's the best i can decribe it.
