ok i had installed a a6 cam and ecu in my a1 and now that cam broke and now stock is back in timing is back to normal and i have the a6 ecu in still and now my car sounds like its vtec and i have less power idk what the problem is this time i love the sound but im afraid of it to

 

the vtec noise kicks in around 4k rpm

 

i can make mine sound like a vtec or cammed if i punch it around 4500rpms (totally noticeable)....i never knew what it was. Never really looked into it either.

 

ill get a video and put it on youtube and post link

is it doing it when you head towards redline or just everytime you get over 4000rpms? mine does its from like 4500-6500 if im punching it. I have no idea what it is but it sounds cool lol.

 

That sounds like your hitting a rev limiter in that video. Is your check engine light on?

BergRacing21,
I think that sound you hear is your engine hitting it's peak tq & hp RPM range. It is enhanced even more if you have a cold air intake and a tube header.

 

i was never hitting redline and when i just regular driving not flooring it it makes the vtec noise i never hit redline the car has 300,xxx miles on it

 

OK then I didn't hear anything but a loud exhaust or open throttle body and a few quick throttle blips.

I'm sure what you are thinking is VTEC is simply the power band of your engine. Like I said before. With the stock intake piping and exhaust removed it is enhanced. I'm sure running an A6 ECU with an A1 engine isn't going to hurt anything. Probably not going to give you any added performance without the cam and intake though. The fuel trims will level out and it will act just like your OEM ECU.

I used to get that VTEC feel all the time. It would actually set me back in my seat a bit when stretching out the gears going up a highway on ramp. It would be going along nice and smooth and then around 4500-4700 there would be a bit of a kick.... that's the sweet butter range!

All I had was a chipped ECU, 255cc injectors, SRI, ported IM and a 4-2-1 header with 2.25" collector and exhaust.

 

ok but theres no vtec kick my car got slower and it sounds just like vtec and its a f22a1 dose it have something to do with valves cuz we ajusted them and i want my power back it used to burn through 2 lights in first and now it dose 2 sqwicks

 

If you adjusted the valves properly there shouldn't be any issue there. Should put your PT3 ECU back in your car and see how that works.

 

ok and my new valve cover gasket leaks and its in there perfectly and its anoying and would my timing make me slower?

 

If your timing is off, yes it could make you slower. That is usually pretty obvious at idle.

 

idle is at 800

 

i just put the old ecu in and do you think that a6 ecu was trying to tune my IM and cam?

 

ohh gotcha...i assumed it had something to do with that, i knew it wasn't anything wrong. It's funny cause back in high school when i first threw a SRI on my car you could definitely hear it and guys would not believe that i didn't have a H22 in my car. I'm like "I DONT HAVE VTEC!"

OP, i have no idea what's going on with yours like ghost said seems like your hitting limiter or something is your CEL on? could be in limp mode.

 

whats sri and cel and the rev limiter is at 6.2k rpm i only get it up to 5k rpm cuz i dont wanna blow the motor

 

that comment was towards Ghost but for reference SRI=Short Ram Intake OP=Original Poster CEL=Check engine light.

 

ok i just have stock piping and k&n wet filter and cel has never been on

 

Just like Ghost said, swap the ECU and see how it runs.

 

i did and it hasent changed yet i think it has to get situated with the car

 

What's the point of using the A6 ecu while using all A1 parts. Unless you like the sound, just go back to the A1.
