Ok Ive done it. ECU was sent off to Powerchip today. Lets see if these guys can give me the 11% increase in power they promised. Should be getting it back arond the 23rd. Will get back to you all with Dyno results etc.

 

I'm really interested in your results. I hope things work out.

 

What kind of a car you putting it on, cause I've been thinking about it for a long time too, but haven't really seen REAL results yet... Thanks and good Luck...

 

F___en Fedex. P___ed Off. They misplaced my parcel in there safe bla bla bla.... toys all over the place. Got free shipping for a year. Dont give a rats.......... Will only have ECU on the 28th.

 

Oh that SUCKs, sorry to hear that.... well let us know how it is after the install...

 

and how is Powerchip's service like. Do they help out with ECU removal/installation etc..? Good luck... Let us know if you "feel" the performance difference right away... and any measurable mileage improvements...

 

Ryan and Brent at Powerchip have been fantastic AU customs on the otherhand have been an a total mess

Like anything can be done at 8pm.

Anyway when it gets here I'll tell you all about it. I'll first run a full tank of 98 before the dyno.

I feel like a kid before his birthday

 

LOL, well Happy Early PowerChip Day, hope it'll be a good one...

 

Remeber to put about 100 miles on the car before testing.

 

I was wondering about that. Does it really matter since the ECU is remapped or does some former "learned" calibration remain?

 

In order for any changes ECU, SC, intake, exhuast, cams, etc to be completely learned by the ECU, approxmately 50-150 miles are needed (sometimes more). How many miles depends on the driving characteristics and the ECU's ability to be exposed to more scenarios.

 

Very interesting. I knew that the ECU has learning ability but wasn't sure it would get any better than right after a reset.

 

The "learned" calabration dose still remain. it has to in order to protect the engine. At the time I took the ECU I was running 95 so timing fuel/O2 mix etc will all have to adjust to fit in with the new map. New averages have to be established bla bla Bla......

Just Got word. Powerchip have my ECU whooooooooo

 

So Ben,

has then been any Dyno tested results for the before & after PowerChip ECUs? I thought evosport was working on getting one installed?

any updates yet?

 

We've done a ton of Powerchip dyno's. CLK69 posted his CLK55 dyno w/ the Powerchip.

 

I will search the forum for that later...

but, do you think this ECU is worth it? Many have said ECU swaps in the past have not yielded very much gains since we have naturally aspirated engines...

 

Both my CLK430 and my E55 have Powerchip ECU upgrades. The CLK still lacks power in lower RPMs but the midrange from 3-4500 has really improved. It is much more fun to drive now.

The E55 had the biggest improvement. G-tech says .1-.2 quicker to 60 and 38HP but I'm guessing 20-25 based on Powerchip info. Low end, mid range, top end all improved. Especially the mid range. I can break the tires loose at any speed in first gear. Traction is seriously a problem now when letting the car downshift into first gear.

It was well worth the money.

 

Any of you know about http://www.speedtuningusa.com/ or have had contact with them and why they would do it fraction of Power Chips Price, How legite are they??? Thanks...

 

E55AMG99,

I was wondering if you could tell me what ECU chip version you purchased? Was it the 91 or 93 version?

I also live in the Bay Area and as you know 93 octane is not available at the pumps so I was just curious what chip was delivering the type of performance you stated.


Thanks,

 

is the 98 Gold. Its almost here. Woooohooooooooo
Wonder what gains i'll get, 10% will do. Any bets what its going to be?

 

CLK430 got the 91 version (19HP) since wifey drives it mostly. The E55 got one that was neither 91 nor 93. I think they called it 91 plus or something like that and want you to run booster if you plan on driving it hard. They said to expect about 20HP. The mid range torque is amazing.

I use a mix of 91 and 100 race fuel from the 76 station on Foxworthy and Almaden.

 

It is good to know which version I'm going to ask for the E55, I drive it hard 85% of the time.

 

since you got the 91 version for the CLK... are you running 91 octane or are you mixing it with the 100 octane racing fuel?

how's the performance difference between running 91 octane compared to mixing it with racing fuel (granted that you've tried higher octanes)

thanks

 

I run 91 in the CLK and don't think I've ever tried anything higher. Never put the G-tech in it either. Too lazy I guess My wife would suspect I changed something. "Honest honey, it got faster all by itself"!

In the E, my butt dyno can't feel the difference between 91 and 50/50 mix with 100 on the first run or if the car and air temps are cool. After a hard run or two, the performance drops a little. On hot days, the performance drop is VERY noticable if I run 91 and drive it hard. In fact when it's hot, the engine misses so bad over 53-5400RPM that it loses almost all power unless I mix some high octane in the tank. However, this is only if the outside temps are over 95 or so.

G-tech says 4.9 to sixty on the first run or if it is cold outside. 5.0 otherwise. Before ECU upgrade it was 5.2. My G-tech tests were on a full tank of 100 but I did not drive the car very far after the ECU was installed. I find out now that I should have driven the car for a couple hundred miles to let the computer adjust. Oh well.

 

so... are you saying that with the new ECU upgrade, under certain environmental conditions that your car will underperform a stock car of the same caliber?
