Hi,

I am thinking about remapping my ECU.
From ebay I saw two interesting products.
Anyone have any opinion?

Thanks!

Eh, Leading company my butt, I've never heard of those companies.

My solution is to call Evosport and ask what they have for your car. They are reputable, and they know what they are doing.

 

Im running a Powerchip,93 Gold.It works great,car is faster,mileage is better and they're reputable.

 

stemags, is the chip the sole performance mod, apart from the remus, that you have done? How's the speed now etc? Cost? Do you pump 93? I can only get 91 here in Cali.

 

I have a Powrchip and didn't notice much. (kind of a waste) My new main concern is getting the car dynoed at having it run too lean.

I've had chiptuning done by Wetterauer, Speedtuning USA, and Jetchip. All three worked flawlessly, provided noticeable power increases, and mpg stayed about the same. On my E300, I took out the ECU and sent it to Oliver at Speedtuning. He does the tuning that day and next day airs your ECU back to you the same day. It helps to have a second vehicle to drive Anyway I know a few and have read about several (more than 20) people getting and loving speedtuning chips. He actually may have several different power level upgrades for your particular model. Some engines can handle the more agressive programs if they have fueling and intake improvements done. For the most part though, normally aspirated gasoline engines stand to gain the least from chiptuning. Turbocharged cars can gain significant boosts, and diesels even more. My chip got me +42hp at the wheels and 60 more pounds of torque on a dyno. The butt dyno is also very happy.

 

so what do you think is the best one time upgrade for regluar gasoline engines? I hope that you will not say super charger haha

 

Diffusion - I'm not a high performance expert and don't claim to be, just sharing my experiences. I can't seem to leave anything stock for very long, so I have tried a few things.

I think it's hard to answer your question if by one time upgrade you mean just upgrading one part. Almost every mod you do seems to require other mods to support it. Add larger injectors you want a fueling map in the ECM to support it - then you probably need a larger fuel pump, gauge, etc, etc. A lot of people like to throw on bolt on parts without much thought to the effects they will have on the rest of the vehicle. My advice is to decide what hp level you are going for and plan around that. If you want big hp, plan on a lot of mods, not one. If you want a small but noticeable hp gain, get a chiptuning program, a better intake, and exhaust system. Sorry to say that dropping in a K&N filter or just an intake or exhaust by themselves will not get you the improvement you're looking for. Don't believe the ads saying 15-20hp from exhaust, 15-20 from intake , and believe yo'ure going to have +40hp. Probably more like 5-10 total on a stock engine, and that won't really be noticeable. Also if you do a significant amount of mods to increase the performance, I'd recommend slightly shortening your oil drain interval, or doing an analysis to determine proper intervals.

In my E I have been typically changing the oil every 7500, but since the chiptuning I am dropping to 5000 mile changes. In my specific vehicle, the chiptuning adds a lot of fueling, which in turn creates more soot loading in the oil. There is only a very small difference (I always do oil analysis), however I'm finicky

 

Mario,

Keep us posted with your dyno results and A/F readings, I'm curious to know

 

The performance chips typically never lean out your air fuel mixture. They typically increase fueling, increase injector duration, and increase the engine's timing, all very close to the stock parameters. Some of these changes will require the use of higher octane fuel, and sometimes more airflow in/out to compensate for the additional heat/timing.

 

Thanks to all!
I learned a lot!

 

Doc,,the speed difference is noticeable at speed,like hitting it when you're already doing 60,it jumps out there nicely.It gets better mileage per gallon,I'd say 20 miles per tank better than before.It cost about 600 or maybe a little more.Throttle response is also improved.Also have the K&N filter,and the EVO pulleys are not yet on,but will be soon along with Iridium plugs,then its off to the Dyno to see where Im at.I do use 93 Octane,just went down to $2.03 in Jersey City(Hess)

 

how about suspension?

Steg, I would love to see your car. I am just affraid that when I start modding my car, I will start having mechanical problems, and not to mention sensor problems.
Since we can't be too far off, I would love to see what you did and how it looks, etc.

 

Sure Diff,we should be seeing all the local Tri-Staters at the meet we're looking to have on 1/29,(check events forum)try to make it.
I have'nt had any sort of problems with any mods so far,thank God,cause like you Im pretty particular about the car.

 

I am thinking of going with the speed tunning chip.
I think it is the best price . what would you say is the best chip??

 

Sorry,forgot to answer that one,altho I do like the look of the lowered cars some of the guys have here,I cant say im ready,I still put 5 people in the car periodocally.It would not be a good ride with all that weight. And the way the car handles with the 17" GY F1GSD3's for summer,I dont need any lowering

 

Mike,I can only report from my own experience.Powerchip people were great.the product was as advertised.Even when the first remapping was done and the car acted funny shifting,and the cruise control was acting up,they knew exactly what to do,remapped it,got it back to me quickly,and voila,,,no problems at all.Im sure you will want to compare prices,get other users reactions to the different chips out there,and make an informed choice.
Good luck

 

How about Eurorev?

Anyone knows about this company?

 

My E55 was done at EuroRev by Jesse. I have had no problems and they did it on site, took about an hour. Jesse use to work for Powerchip. The programing is near the same.

 

Thanks, E55Cent!
