Anyone chip their E300 non-turbo? - Page 2 - PeachParts Mercedes-Benz Forum

On my New Beetle TDI, I had an UPsolute chip for 30,000 miles, which made a huge difference. After I had run the UPsolute chip for a while, I switched to SpeedTuning's highest level chip, which was smoother and more powerful.

Both SpeedTuning and UPsolute yielded a ~40% increase in torque (155 lb-ft stock, 210 lb-ft chipped) from 1900 rpms to 3500 rpms. Keep in mind that everything on this engine is controlled by the computer, so chipping is everything. On the Mercedes diesels, with the exception of the 1990s cars, almost all functions are mechanically controlled, so chipping has a limited effect.

A friend of mine has a 1992 300D 2.5 Turbo, and the wastegate is computer-controlled (to the best of my knowledge), so I would assume that chipping the computer would make higher boost pressure, which is dangerous considering that the engine is not intercooled.

Chipping on non-turbocharged engines never produces a large increase in power. It's usually only 10% or so. Chipping a turbocharged engine car yield an increase of 50% or more.

I hope this helps.

Hi! I have done chipping on my 97 E300D about 10 mo. and 40 000 miles ago.I send my ECU and about 350$ .After 3 days I have it back.(bougt service thru E-Bay)Promises was 25% more Hp and tq and 10%save on fuel....In my opinion SHE gain 10-15% more power and save 1mile per gallon.I am really happy with HER right now.Much easier going thru gears and uphills at 3000 rpm on flat SHE cruise at ease 77mph.I install K&N filter but do not see any diffrents.Only problem my wife now drive my car also,beafor was tooo slow....My0.02$

Just for the record... After viewing the w210 info CD... the mechanically controlled injection pump governer was replaced in '97 with an electronically controlled fuel quantity actuator. This would most be a reason to why ECM reflashing or "chipping" would help this engine...

Anyone else learn of any other new info...

Waiting for uncle sam's refund and my little hesitation problem to clear before I send off my ECM to SpeedTuning

michakaveli, I haven't seen you around for a few days. Did you see this? LightMan's Thread

Lightman an I have been talking about the chipping for like a year. He read in the w210 Technical CD that he has the stronger tranny. I just wanted to hear if anyone performed the mod on their non-turbo E300.

Depending on how much I get back if any from uncle sam this year, and, on the situation of my wierd engine hesitation I want to send out my ECU as well.

I'm still getting hung up on one small issue--how can you get higher HP figures by just increasing the quantity of fuel without a corresponding increase in the volume or density of the air entering the combustion chamber? Am I missing something? I'd love to be able to tweak NA diesel performance output, but I'm just not sure it can be done to much extent. I'm definitely open to the concept, but I wish I could see some objective info first.

Rick Miley · #22 01-23-2004, 09:56 PM

The thing is that they're tuned very conservatively at the factory. The engineers in Stuttgart have to balance performance, economy, and emissions (especially visible smoke). We, on the other hand, can tune them for performance with worrying about CAFE standards and EPA regulations. You can easily turn up the fuel and get some more power, but there will me some smoke.

Maybe a sour note but, is it responsible to ignore the smoke/pollution issue just because we can. You can purchase a fast vehicle that is within the legal emissions standards.

Zeitgeist · #24 01-23-2004, 10:27 PM

I agree with you about the conservative tuning from the factory Rick, but NA diesels are constrained by the volume of air that can enter the combustion chamber relative the the amount of fuel injected.

On the other hand, our turbo engines can vary the amount of boost pressure, and consequently the amount and density (w/intercooler) of air entering the cylinder relative to fuel quantities. I could add an intercooler kit (w/ IP adjustments) to my OM 603 and put out close to the same HP figures as your OM 606 in stock form. I suspect your ECU maps boost pressures and fuel volumes very closely, and consequently can be tweaked to expand the mapping parameters to allow the boost and fuel volumes to increase together optimally for max power output. VW tdi's also benefit from this chipping upgrade for the same reasons--90hp v. 130 hp I think. I'd love to try this on our Passat.

I just don't think NA diesels can be chipped in this same fashion, but I could be wrong. In fact I hope I am wrong...

Diesels typically operate with an EXCESS of oxygen in the combustion chamber. Even at full throttle there is more oxygen in the combustion chamber than there is available fuel for combustion. Adding more fuel will result in more power - and as we have heard more smoke/emissions.

I'm glad to hear the 97 and up pumps are electronically controlled - I had written you guys off as a bunch of nuts. I was going to suggest you might want to try a tornado air induction swirl system as your next performance mod!!

The great thing about performance tuning on diesel engines is that you can have great power but as long as you don't use the loud pedal too much your mileage will not suffer at all.

Keep on smoking...

Sombody read technical CD of w210 engine? Such thing exist?I am dreaming about day when I open hood and named all the"Things" and how it works...Where I can buy it?

deuce · #27 01-26-2004, 10:11 PM

Any chance this will work on a '96 E300 non-turbo?

Based on the info off the w210 tech CD, it says 97 and up are electronically governed.... So logically I'd say no... but you never know.

Figures....

I did have my mech adjust the kickdown and the shiftpoint? a couple of months ago and it seems to accelerate much smoother and quicker than when I bought it. But, that may be my imagination.
