Does anyone have info on removing or replacing the Speed/Rev Limiter on the 2.2 Ecotec engine ? Secondly, is it even possible right now with whats available or must I wait for something to hit the market ? I'd really like to remove that restriction before I go any further with anyother upgrades. Thanks!

 

nothing is available ATM sct is working on it.. will be out around march/April area

 

There are many threads on this topic, please try a search first before making a new thread.

At present, there is no tuning available for the E16a engine computer in the 2.2L 2005-06 Cobalts. You would not be able to change those parameters until there is.

 

if you want to remove your speed limiter, make sure you upgrade your tires. the limiter is based on the tires that you have, and going over that limit you can expect a blowout.

 

removeing the Rev limiter is a bad thing.. well it would be for me anyways sometimes i forget to shift


.

 

VSS cutoff switch

 

u forget to shift?????????



wont ur dealer turn up the ECT if u have better tires?

 

they might bump it to ~125, it depends on your dealer.

there's far too many stock, or mainly stock, 2.2's that are asking about this though. I woudln't suggest this at all unless it's something you need for safety at a drag strip or road course.

 

105 sucks. i said i want fast. lol .....the worst scenario ever: Tell ya what, we ll have a race. the person who makes it to 105 the fastest wins!!!!!!!........what does 200 HP do for ya when you have ta stop at 105??? not ****!

 

By the time this engine is capable of making 200 HP, it will also be able to change that limiter.

 

I don't stop at 105 mine stops at about 160

 

He was talking about the 2.2L LS/LT's.
You have a 2.0L SS/SC if your speedo goes to 160.

 

105 sucks, is there anything for 07 ls/lt's??

 

Not yet

 

Yea first day i had the car i got it out on the freeway and supidly did 105mph just to see where it toped out, i was like "WTF!" but after having some time on the stock rubber im glad its there, thoes tires were ****.

 

i have a 2.2 and i've gotten to 120

 

Yep it does suck! I can hit my speed limiter in 4th gear at only about 5800 rpm's. But what I can't figure out is how I ran a 16.2 when my car was bone stock and now I have a sts, cat back, and intake and ran the same exact thing!! Believe its the bald tires not grabbing at all!!! Wich goes back to what every one else said above about needing better tires!!!!!

 

me too

 

how do the breaks hold up to higher speeds?

 

Well if your unfortunate enough to not have Anti lock brakes then well......Hope you can think on your feet and not just slam the brakes because they will lock up and you will slide like your on ice. But im sure the upper models with anti lock brakes work pretty good.

 

with better stickier tires they wont lock up, or should be less prone to lockup, but overall is there a lot of fade at higher speeds or do they work well all over the place

 

There's a pretty decent amount of fade. I know it's freaked me out a couple of times.

 

lol, it's REAL tough to explain to a dealer why you'd need that turned up.

the brakes on my car stop like a mother, the only issue is that the factory rotors seem to suck, as everyone has issues.

 

eh not really, it really depends on how your dealer is. I'm pretty good friends with almost every dealership I go to, and they all know my car, what it's used for, and the sites/groups I run or am in, so they wouldn't mind. I still went to have a good friends who happens to be a tech do it though on a slow day as to not get any of the other guys in some sort of trouble.

I dunno, the stock brakes as said weren't too bad but you could definitely feel fade. once I got rid of the stock rotors and pads for powerslots and hawk hps they're far better though, almost feels like a different car now.

 

anything new about tuning or are we still up that creek
