I am thinking about throwing a chip into my car. I was hoping not to spend an arm and a leg though. I am looking at Both Speed Tuning USA Chips and Power Chip. Is there Any known problems with either? Why is power chip's chip so expensive compared to the other one? and if i install this chip, will it affect the adaptive transmission? Will it remove the adaptation? I really do not like the adaptation of my transmission.

A lot of people said that Power Chip is better.
However, I have no chance to compare.
Good luck!

Im pretty sure that powerchip is a plug in unit that you your self install and use while speed tuning requires you to send in your ecu and they will tune it(which keeps costs cheaper).

ok i thought it was like a quality issue or something like more people prefer power chip so they made it more expensive or something.

How about the kleeman?

I'm in the same situation, I'd like to get more power out of my 97 E420 as well.

I'd really like to hear from someone who has chipped a 97 E420. Powerchip claims about 20 more horsepower and similiar torque improvement.

I wonder how much power if any I would gain by swapping our the rear stock muffler, I've already removed the resonator and put in a Y pipe..., which I think did help with power a little...

h0rn3t920

well I really would like to know if theres any advantages of Powerchip opposed to Speed Tuning.

HOWSER

Sorry to be the pessimist here but I cannot imagine a chip doing anything to gain more than a couple horsepower here. Unless you are doing other major mods, more than just exhaust, I would think that it would be a waste of money.

Has anyone here dyno'd both pre and post chipping? We can't believe what the manufactures say.

h0rn3t920

no it does make a difference, im just trying to find whats the better value thats all. Just check out the other people on the forum that got their cars chipped

HOWSER

Just curious, just how much of a performance gain are you expecting?

h0rn3t920

idk like 15-20 hp but people that have these chips says it makes a difference in the way the car drives and i still dont know if im going to get it

HOWSER

Thanks.

Maybe someone will chime in with comparitive numbers. I personally don't think that a chip can provide those numbers in these cars. Maybe if FI was involved it could happen, otherwise I think it's a waste of money. IMO, even if they could provide an additional 15-20 hp one would be hard pressed to really notice an improvement in performance. You'd need twice that much increase in power to realize an improvement.

Keep in mind, these are just my opinions. I hope you are able to find what you are looking for.

The chips can increase the horsepower. Some chips make a dramatic difference. In the diseal cars, the chips increase the horsepower alot and the torque 50+. check it out someone did it on the fourms i dont remember who though.

In diesels, one could chip the stock engine(say a dodge) and get almost or more than 100 more horsepower and torque depending on what they use.

I found a article on tuning the m112 in a powerchip pdf but I couldnt find the 420's v8 engine in thier books. Best to just give them a call first but im sure they can do it, seeing as your car is a obdII vehicle. In the e320 they gave a 40hp gain.

I wonder if powerchip could adjust my computer to make it more turbo friendly .

You are sending your unit to Power Chips to reprogram. It does make a difference in the 320 V6 models. They do have extensive dyno numbers for you to look at. Most chip companies run similar gains. Good luck.

ohlord

and the maf remain the same,you are doing nothing to the engine to demand the need for a fatter fuel curve or more air,nor anything to make the engine able to take in more air,i.e. head work,valve work,cam work.
The gains are highly exaggerated ,the cost per return gained is silly.Run a base line dyno test exactly as it sits,and run one with no other changes than the chip you put in and post the numbers.Are you going to the track with the car?Are you looking for more real power?You are going about it bass ackwards


40 H.P.
They look for guys that believe that crap

So what do you think these chip tunes really change, and more importantly, what do you think would be the best bang for the buck in terms of real gains for little money? As you said before, we are talking about 10k cars here, so anything more than a few hundred bucks would be silly.

ohlord

might modify closed loop operation of the O2 Maf closed loop circuit to the ecu,but Mercedes has done a pretty good job of opening up the system at full throttle.That is why the engine is still pulling when the factory governed top speed limiter kicks in.The chip may advance timing a bit,but are you going to go hunt down a diet of 97-100 octane fuel to feed it?
A properly done chip or MB tuner ECU when needed is going to be done on a per car basis because someone actually did something that requires the need to modify the timing,fuel map etc. a lot of major changes to the engine.
Look at the price of headers,look at the price of cams,or head porting.The only low dollar h.p. trick and done right is still not that low buck is a good exhaust system ,dual all the way back with an h-pipe and leaving cats and o2's functional.The ecu will adapt A/F ratios and the car will pull more torque.
1998 and newer fly by wire throttle models,do a trans adapt reset for free and be happy with that

So what you are saying, Oh Lord, is that all these chip tuning companies including RenTECH, BRABUS, etc are liars when it comes to their tuning of ECUs and that the posted dyno results are pure BS and not representative of any car they are advertising their gains for? BTW does AMG chip tune on their models? Anybody know? Just curious.

ohlord

and any of the real tuners you will note provide chips so that owners of models that have installed real power gainers can take advantage of those gains.It would be silly to install a 12,000 buck Kleeman supercharger on a m113 and then not modify the injectors,the injector pulse width,the injector timing ,the ignition timing etc.
just as it is silly to put a chip into a bone stock m112 M113 M119 M104 and expect 40 h.p. out of thin air.Let's say we chip tune a m112 and raise the rev limit 500 rpm it still makes max power at 5500 rpm so all we did was wind the **** out of it for nothing.Change the compression,change the cams profiles,open up the heads,install headers,then wind it up to the new chips higher rev limit and the whole equation is changed h.p. goes up the torque curve gets fatter and moves up and you have gained.All again for about the cost of a low mile 2000 E320.

It's all very disappointing. Too much work. I think I'll just buy a Civic.

Don't forget the huge wing.
