why? you say to be smoother but using the clutch is what would make it smooth, no?

 

Well, one thing I know of in the MR is that with the clutch depressed (all the way) there's a built in 2 stage rev limiter... It uses the clutch safety switch to initiate that.

Common to all EVO's... Between shifts, when you step on the clutch, it also uses that clutch safety switch to switch to a different base map that supposdly reduces emissions. Read it right out of the FSM... Anyway, that might have something to do with you pulling into neutral without using the clutch...

Another thing I can think of is that whatever you touched in the ECU may be causing the car to trigger the fast idle mode. (when car is cold) It's a far fetched idea, but it may be a possibility...

As for your TT affairs, It's not necessary to tap the RPM wire on the ECU of the TT to get full auto mode to work...

Good luck in chasing that problem...

 

All I was saying above was... when I let off the gas and am going to slow down (while in gear), instead of pushing the clutch to go into neutral, I simply pull out of gear.

I've gone for a test drive and got some more info...

Here's what I've found... When slowly letting the RPM climb above 5K in 2nd gear without building any boost, and i let off the gas, it works correctly. However, if I build boost to 5K in 2nd gear and let off... there's no "kick" the RPM stick and slowly drop. Even if I pop the gear into neutral during this, it still sticks and VERY slowly drops (in any gear). Unless I push the clutch, then it drops normally... So, if I build boost at any time in any gear and hit above 4000 RPM and let off the gas, the RPMs will float there.. The RPMs seem to want to stick between 4000-5000 RPM...

 

i suggest you start pushing in the clutch when going in to neutral then. the fact that the car is doing something wierd, when you don't use the clutch is a sign you're doing something that the car isn't intended to do.

 

that clutch button under the clutch pedal also lets the ecu know that you're on the clutch. Without that switch, you can't turn your car on.

Something better than fuel cut or kill switch. I've been thinking about using that as my security feature.

Don't tell anyone. lol

 

Are you sure you're understanding what I'm talking about? All I'm saying is that to go from a gear to neutral, you don't need the clutch. In fact, why wear the clutch by pushing it in to go to neutral when you know you're doing to stop? I can't think of any reason why doing this would hurt anything, nor have I read anything. If someone else has, please let me know.

 

i know what you're talking about. i have years experience in rebuilding manual transmissions. i also know is possible to shift gears without the clutch and not make any grind noise. would i ever do that? hell no. just because it's not making sound doesn't mean its not causing unnecessary wear and tear. you aren't putting measurable wear on clutch by depressing it, that is what its designed to do.

but whatever, it's your car.

 

I was having the same prob. with my MR... after install 272/272 cams i dont see it anymore so I felt as if there really wasnt a problme for me.

 

guitardave24: I have the same setup as you, I don't consider it a problem by any means !

 

Dude that's cool, but again, by that statement I know you are not listening to me. I know what you are referring to but I am not shifting gears without the clutch. I am understanding "shifting gears" would mean going back into gear w/out the clutch (going from one gear to another). I never do that. I am merely pulling the car "out" of gear into neutral w/out the clutch. That is ALL, nothing else. When you slowly lift the throttle and pull the gear out w/out the clutch, it is very smooth. Nevertheless, the point is moot because it is still an issue because I cannot engine brake at high RPM nor can I rev match when shifting.

Do you track your car? I see it as a HUGE problem. The car feels totally different. For starters, I am unable to rev match like a normal manual transmission car would and beyond that, I feel and sound like an idiot that cannot drive manual because the RPMs don't drop when shifting (it sounds like I still have my foot on the throttle). It throws everything off. Even for daily driving it feels weird and abnormal. It's definitely a problem. Ya know?

 

i know what you are talking about. i know you weren't talking about shifting without using the clutch. i understand that you are just shifting into neutral without the clutch. i just gave you that as an example that you don't have to "hear" noise to do actual damage.

 

That's fair, but with your experience can you tell me what I was actually referring to "does" cause damage? Because I am unable to find any information that it would. That's what I was looking for, of course I understand that damage can be caused w/out actual noises. Know what I mean? Thanks.

 

Update: I uninstalled my mods and brought back to stock. Still occuring...

 

You know what your car is doing. If you don't like it or it feels abnormal, take it to the dealer and have it checked out. I was going to say that maybe those mods you installed had something to do with it, but if you put it exactly back to stock, I guess that was not it. Personally, I don't like TTs and I wont put one in my car. They can cause more problems thaan they solve even if working as designed. Frankly, it's possible that dicking around the wiring to install that useless mod could have caused the problem......

 

Bump cuz i have the same problem. I think im going to try the works throttle body and see if that solves it. If not i will be getting burscher IC piping and a new BOV so maybe that will solve it. I think its mechanical not ECU related. Like there is still pressure leaking past the throttle plate.
