110 MPH wall, help!

[justin84vfr]

Looking for some help here... Here's the situation: I have a 90 talon tsi fwd car running a pretty stock setup, stock 14b, some exhaust/intake and porting work, otherwise stock. I'm using a Hallman ES MBC. The problem is no matter what I try the car cuts out with no throttle responce for about 3-4 seconds at exactly 110 mph. I've tried the following: Adjust boost from 8 psi to 15 psi, try creeping into 110 slowly, tryed WOT, same result, even tried with and against wind with the same result. I'm told the first gen cars did not have a speed limiter, and the ones that did cut out at 135ish due to the non-speed rated tires used from the factory on non-awd cars. None of this seems to coincide with my problem. I think I have eliminated fuel cut or boost leaks as it cuts at exactly 110 mph on the speedo everytime. Anybody have any thoughts or advice? Acts just like a rev or speed limiter, though I don't think I'm remotely close to either.

 

[gsx rated98]

yea, slow down.

 

[hubz91talontsi]

Well that was a horrible response =). You may a boost leak but what do i know.

Do you have a reason to go that fast?

Out in the middle of the Bad Lands what else is the boy to do.

I live in South Dakota where its not uncommon to drive for 4 or 5 miles without meeting a single car, and if a car is supposed to go 140+ I want to have that option. Kinda making me wonder what kind of people you are to ask about going 110.... Thats not that fast at all, its the posted speed limit in places in Europe.

 

[gsx rated98]

two things, one your not in Europe, and two why do you think your car should do 140?

To your issues, do you see this problem at lower gears? By this, I mean do you see it at a certain RPM, or just at 110? If its only at 110, I'd have to assume some type of governer is on the car. Know anyone with another ECU you could borrow for the afternoon, I'd try that out.

 

[BootlegGreg]

Your car didn't beat 110 in the 1/4 ,

 

[1992awdlaser]

Thats not that fast at all, its the posted speed limit in places in Europe.

110 is TWICE the posted speed limit on most public roads in THIS COUNTRY.

and if a car is supposed to go 140+ I want to have that option.

You have that option at a race track.

Kinda making me wonder what kind of people you are to ask about going 110....

Look at the mods in my profile. My car will do that in less than a 1/4 mile as is, not like the mile it will take yours to get there.

 

[mavisky]

Something's up with that ecu. Back in the day when I was less than intelligent my little 2.0 nt with some bolt ons would run 120.

Well... I have been in Europe for 4 months... talk to my girl friend about no speed limit autobahn... i think there are only couple left in germany and italy...
most 95% of the autobahn in Europe limited about 130km/h which is about 85mph...
so... 110 is fast... not in a BMW tho... feel like 55mph

I'll try to round up a different ECU and try it. I agree that my car won't hit 110 in the 1/4 mile, however it should go faster than 110. For those who feel 110 is to fast I appreciate your concerns and quite frankly you shouldn't be driving that fast if your not comfortable doing it. For me 110 isn't that fast really. I've hit 145 on my bike, and have an LT1 camaro that I've had up over 150+. Is it safe? Not at all, but then again to much of anything isnt safe now is it? Just have to use some common sense and if your going to risk it do it alone on an open road.

You've just removed common sense from the equation.

 

[justin84vfr]

oh, and it doesnt cut out in lower gears, only 5th.

 

[gsx rated98]

OK, yea check the ECU.

 

[1992awdlaser]

I agree that my car won't hit 110 in the 1/4 mile, however it should go faster than 110.

There is no reason to try and find out on a public road.

For those who feel 110 is to fast I appreciate your concerns and quite frankly you shouldn't be driving that fast if your not comfortable doing it.

Its not that I am not comfortable with it (like I said my car does it in less than 1/4 mile). Its that it shouldn't be done on a public road even if you are a professional race car driver. I am completely comfortable going that speed and faster. I am not comfortable putting unknowing lives in my hands. ANYTHING can happen no matter how good you are at driving. When you say comfortable I think you partially mean ability also. So for that I will say I would love to see you get in my car and be able to drive it anywhere close to what I can. I bet you run a second slower than me in it.

For me 110 isn't that fast really. I've hit 145 on my bike, and have an LT1 camaro that I've had up over 150+.

You think that makes you special or something? If I cared about top speed I would get in my friends rx7 and go 200mph in it. But I am not stupid enough to do that on a public road and there are no race tracks close enough for me to do it at.

Not at all, but then again to much of anything isnt safe now is it? Just have to use some common sense and if your going to risk it do it alone on an open road.

I see no common sense being used at all here. You never know if you are completely alone unless it is a closed road (which would still be dangerous) or at a race track (where there are medical professionals waiting for something to happen). Even if you knew you were alone what if something did happen like a animal come into the road or a tire blow out. Then since you are alone your either dead, going to be dead before you get to the hospital, or your going to have major problems once you get to the hospital. And what if a kid had shown up out of nowhere even though you thought you were alone? Do you think you could handle telling the family that there son/daughter is dead because you thought you were alone? And because you thought you were a good driver and nothing would happen?

I could go on all day about how stupid it is to do something like this but seeing how you will actually do this I don't think you could even understand what I mean.

Common sense would tell me that if you are on a open road (IE public) then you are not alone.

Don't come here with some garbage about you going fast on bikes and other cars. I can show you real life pictures of what happens at those speeds. I have a friend who is not here to tell you his story because of those kind of speeds on open roads. And if you think that is sad think about the person who was in the vehicle he hit. They are still alive and have to live with the memory of some guy flying through their windshield and landing in their passenger seat Oh yeah good thing in his case there was no passenger in that seat he landed in. But go ahead talk smack about how careful you are untill you kill someone.

Now that my rant is over, since you seem to want a answer to your question. Will it do over 110 at all? Say will it do 111 in 4th? If the car will not go over 110 no matter what then it is in the ecu. You may have a ecu from a different model or it could be a eprom that someone has decided to make a speed limiter in.

 

[SOADweskey]

This thread is a mess, obviously he has a problem as his car should have no problem going faster than 110 if it is running right and he is here looking for help with his car like everybody else.

If my car had this problem I would expect help from this site not the criticism that started right off the bat. (After the bike and LT1 comment it is deserved though).

At willow springs I enter the braking zone for turn 1 at 135+ so you better believe I would be pissed at my car if it couldn't go 110 all of a sudden.

 

[justin84vfr]

I understand all of the comment about going to fast, point made and taken. I as SOAD has stated, just want some ideas on how to fix my car, thats all. If you have any ideas great, please share. Otherwise I'll keep my opinions to myself, and others can do the same and we can all gain some knowledge and insight from this site.

will a 91 gsx ecu work in a 90 eagle fwd car?

To answer quickly yes a 91-94 ecu will work. Problem is that one of the wires on a 90 is in a different pin location than on the 91-94 models.

You will find alot of differences in the 90 models compared to the 91-94 models. Some good and some a pain in the but.

I am just throwing this out there for ya. I have a 90 non-eprom ecu sitting in garage. It has not been used in a little over a year but was in perfect working order before I switched to a eprom ecu. If you are interested throw me a offer and it may be yours.

Christ buddy settle down about the speeding thing, we get it. You dont ever speed and your the best driver of the best car ever.

Do you think your special? Sure sounds like it!

Ofcourse you have a buddie with a FD that goes 200mph.

 

[talon187]

i think auto ecus will cut out around 110ish if i remeber correct my buddy had the same issue with his car we changed the ecu and problem was fixed

 

[1992awdlaser]

Christ buddy settle down about the speeding thing, we get it. You dont ever speed and your the best driver of the best car ever.

Where did I say that I never speed? I don't go TWICE the speed limit. I never said I was the best driver either. I said that because he doesn't think I am comfortable to drive 110mph and to prove my car is different than his(meaning faster, launches different blah blah blah).

Do you think your special? Sure sounds like it!

Not at all. I am however smart and won't go twice the speed limit on a public road then try to defend myself by trying to make it look like I know everything about the road, that nothing will happen, or that everything will be perfect.

Ofcourse you have a buddie with a FD that goes 200mph.

Actually yes I do. Do you want to see a picture of it? If you do go to photobucket.com and look up 92awdlaser as a member and look at the album.

If you want to respond to this do it with a pm.
