1995 3.4L Tune and govern remover!

[Nikos95]

Okay I am getting ready here to get my SLP cold air intake, my 22lb injectors, driveshaft, shift improver kit and inline chip for the 4L60E pile of crap, new plugs, 8mm wires, accel coils, new cooper cobra tires, eaton posi rear end, and of course my new *empty* cat, rksport headers, relocate my iat, and flowmaster cat-back.

Now to get to the fun part, its time to start thinking about ECU re programming. I can't find anything for the computer but a modual from JET but it "DOES NOT" take out my speed limiter, and I am in no chance in he## going to deal with that much extra work to have the car top at 108mph! useless cause me to lose to a honda civic!
<un acceptable!>

I checked hypertech they only make a system for the 3.8L. I refuse to get a 3.8 on the fact that it doesn't not rev as fast properly built, and does not hold up to the extremes as well. No offense to 3.8 owners but its not an engine if you are looking at seriously going all out on it.

So with all that, does anyone have a idea wher I can get a chip or a programmer for this car? Or know a company I can contact to have my computer reprogrammed?

Thanks

Last I heard the only place that did 3.4L tuning (fastchip? I think) doesn't do it no more...


I think the biggest problem why all the big built 3.4Ls don't do so well is because of lack of tuning. And since my old 3.4L was stockish when it comes to the motor it got by fine.

Man.. I just have to reply to this one.

fyi... there are a handful of 3.8's running 9's..

The 3800 will handle more power than you could ever throw at it.. and its also PROVEN to handle extremes.

It's common knowledge how great of a motor the 3.8 is.

the 3.4 is just as good, it just lacks in tuning [img]tongue.gif[/img]

Fastchip.com will do a "basic" performance tune for you which also removes the limiter and can adjust for different gear ratios. According to those who have inquired however, they will not make adjustments to their standard file for a "custom" tune.

Everything you have listed to mod is pretty basic except the injectors. Not sure that would be a good idea, that's a pretty large increase, and no way to tune for them.

Just wondering why this engine isn't used in any real form of racing shot of a few drag racers, they don't use it in super 6 dirt track, they dont run it in nascar, they don't use it in edurance racing.. the 3.8 is a nice engine I won't lie, but it is not a race engine, I have seen ethanol running 3.4s runnin in the means of 600hp at 16,000+ rpms. This is not something the 3.8L is capable of simply because the piston walls are too thin. The 3.8 is a great street engine, no doubt about it minus the problem with the intake plenum in the series II. But it is not by any means a true race engine. Being the 3.8 was designed by buick a long time ago and the 3.4 was built off the 305 V8 which is one of the strongest v8s gm ever produced.

And trust me, nothing can take the power and punishment I will put on it. Lol I drive like a ****ing nut, and don't take that with a fly. I always run red-lined, because I like winding tight roads. no engine deals with red line for extended periods of time.

my first few mods will be: intake, headers, exhuast, throttle body, and intake manifold. why? because these are the few things that will really "wake up" a 3.4l engine.

They ask for a lot of money for that basc tune. That sucks. Someone once told me that according to them, the 3.4 tune gets about 16-17 RWHP.

$300 is what they told me. Changes/updates are $125 if you ever need to send it back. It's a little more expensive than some places that do 3.8 tuning, but there's a couple of those, price competition and all.

I dunno. When a Jet module or the Hypertech (when it was available) both went for $300 new, seems like a better choice, especially considering neither the Jet nor the HPP can adjust for gearing or make other changes, and the Jet doesn't even remove the limiter.

That power estimate is probably right. I remember the Hypertech dynoed around 15 rwhp.

when it comes to tuning the 3.4L there is just nothing out there unless you go with megasquirt or a complete stand alone PCM. with megasquirt you can control fuel and spark. I haven’t had any dealings with it personally and haven’t had the time to research it like I should before I hand out advice, but I think that’s the best way to go.

the jet doesn't? isn't this false advertising then?

No, it's apples & oranges. This is what doesn't wipe out the speed limiter... Jeg's Catalog What you linked to is just a speed control, it won't tune anything. Maybe if you combine the two, you will be alright. Or you could unplug the speed sensor, but then your speedo won't work either.

So $250 for the Jet Power Module + $140 for the Jet SCU.

No listing for manual trans?

I have heard the SCU prevents cruise control from functioning properly. Maybe not a big deal to someone, but something to keep in mind.

Rob </font>[/QUOTE]are you saying you have to buy both the Speed Control Unit and the Jet Power Control Module in order to eliminate the limiter? the speed control unit alone doesn't work?

apparently the guy on this page with the 98 GMC says that the scu removed his limiter:
