The engine produces 215 bhp @ 5700 rpm and 230 lb.-ft. of torque @ 3000 rpm. Its 6000 rpm maximum operating speed is electronically limited by interrupting the fuel supply. The engine is tuned to provide high torque over a broad range of engine speed for optimum drivability. 90% of max torque is available from about 2300-5300 rpm, 98% of max torque is available from 3000-4500 rpm.

Would love to know if the ECU can be changed too.
Get some good pics of you launching if you can change it.

 

I hope this works safely and no problems in the long run. I hope they will come out with something that can toggle through and shut it off and turn it on. I might just keep it off just cause it is do annoying one of my main dislike in the xf. I will try to do this to see how it goes. Wish the best of luck for those trying it also. I sure there will be post of the progress and the testing of this fuse and ABS removal. Thank alot for eveyone's feedback and info especially to vsilvia.

 

Oh just curious. I must of missed in from the readings, how did you come across the info about removing the fuse to turn off ABS? Thanks.

 

Xfire Service Manual. Then a little deductive reasoning and real world testing.
With a little effort, some parts and wiring, I think it would be possible to actually use the Traction Control switch to disable it temporarily. I will look at it and see what I can come up with.

 

So have you guys left the fuses off or did you guys not like it and put the fuse back on. And how has the progress been? I didn't have the chance to pull the fuse yet it's been raining here.

 

Pulling the fuse isn't going to kill anything. Remember the car is a fly by wire setup. Everything is run off of electrical impulse. If you are not careful, the cars M. O. can bite you in the as*. What I mean by M.O. is, these cars are notorious for over-voltage. For a long time I thought that the car was under Powered. I figured out that it is not under powered, but actually it puts out more power then you think. Were the problem lies with these cars ability to regulate power. If anyone has a real rough idle, check your fuses, you may find that your ignition controller fuse is toasted. That is one of many places to check for faulty parts. Because for a while. I was calling this car the my Car the Miss-Fire. What it came down to was, the ignition timing was that of an E class, and was screwing everything up. Ya it pissed me off a little bit, to think that this thing was set up as E class car as far as the fuel to air ratio's etc...etc... So you don't want and cant kill the traction control, if you do your car probably won't run.

 

Following my instructions above, it disables the CAB (Computer Assisted Braking) unit which disables the ABS system completely which disables the Traction control completely. It does not affect the base braking system at all as far as I can tell.

The following is taken directly from the Service Manual:

The primary functions of the Controller Antilock Brake (CAB) are to:
² Monitor the Antilock Brake System (ABS) for proper operation.
² Detect wheel locking or wheel slipping tendencies by monitoring the speed of all four wheels of the vehicle.
² Control fluid modulation to the wheel brakes while the system is in an ABS mode.
² Store diagnostic information.
² Provide communication to the DRBIIIT scan tool while in diagnostic mode.
² Illuminate the amber ABS warning indicator lamp.
² Illuminate the brake assist (BAS)/electronic stability program (ESP) lamp on the instrument panel when a traction control event occurs.
The CAB constantly monitors the Antilock Brake System for proper operation. If the CAB detects a fault, it will turn on the amber ABS warning indicator lamp and disable the Antilock Braking System. The normal base braking system will remain operational.

 

Looks easy and I'm scared to try this but I will tomorrow. Thanks for all your help to solve my frustration. Hopefully it all turns out well and the way I expect.

Thank vsilvia and others for feedback.

 

hey elite how did you make out?

 

It worked but not what I expected. It brought out better launch but there are still some restriction that I can't pinpoint. I haven't tried burning out but I have took it to the tracks and it made a difference in the traction not kicking in when you didn't want it to. My time was 14.588 1/4 vs before it was low 15s on hot summer days with traction kicking in during launch and slowed my times down. I'm expecting better times in the winter. The light keeps illuminating but it take less the 5 mins to put back to original. Thanks for all your help.

 

Is your car a 6 speed or auto? The thing that kills the launch with the 6 speed car is that it has a low rpm limit when the car isn't moving so you can't dump the clutch and break anything. That has to be addressed in the ECU unfortunately. I am going to try to come up with something to fool the ECU out of doing this, but I just don't have the time or electronics know how. Any electronics gurus here that can design a simple device based on an idea? If so, contact me- sales@joepmbc.com - I may have an idea to trick it, at least on the 6 speed cars.

I have the 6 speed and exactly the problem at first I thought was the traction but it is not. Another problem is not being able to dump the clutch and launch the way the crossfire can be launch with it's power. Thanks for any more assistance than what I have already gathered. I wish to show the cars potential without as many restriction like other cars that are able to burnout and launch without any complications like the crossfires dishes out, it truly drops my moral.

p.s. I did better burnouts and performance driving with my Acura RSX type S than my crossfire and I like the crossfire but the ride is different from all other competitors like mustangs, RSX and S2000. Crossfire needs to be a easier and friendlier to drive to bring more excitement to the car.

 

Everything you said is totally true. The thing you will have to remember is, this thing is a consumer Mercedes Benz under those fine lined body panels. And unfortunately for about the past ten years, the Head of Daimler ran Mercedes into the ground, unless you were talking about Formula 1 racing. If we had a tenth of the technology in a McLaren Formula race car. We would have a better electrical system, a more Reliable Transmission as a whole (6 spd, as well as the Auto Stick) granted AMG does has contributed with a stronger gearbox, and F1 EGS Program...Wait I think I found that Tenth!
What I am getting at is... our cars unfortunately were basically just a wash from Mercedes all the way down the line to Chrysler. They are pretty much all Frankensteined. I found that at least 35% of the Crossfire line have ECU's and Tranny Modules that would actually go in a 02'/03' E class MB. I'm thinking that is why so many are having timing issues, or rough idles, etc... If they were thinking of keep the crossfire around for a while, and wanted to put money into the system. Then we could expect the new SLK 350's to be put into action Crossfire style with in the next 2/3 yrs. But I wouldn't hold my breath. It would be nice to have that "F-1" Inspired Chassis under my Crossfires skin. But that is just me.

 

Agreed, but the problem he is having is not so much a "problem" a lot of manufacturers have "free rev" rev limits built into their cars mainly to prevent engine/driveline damage. If they didn't have that, people would be braking things left and right and expecting DC to pick up the tab. You would also get people not knowing any better and getting in accidents- then suing DC for not having it limited so the stupid people "can't lose control on take off". The BS they go through in the auto industry is ridiculous. I know the last example was far fetched- it was meant to be semi- sarcastic (although I wouldn't put it past someone), it is mainly for drivetrain protection.

Hey Dan-

I just called EuroRev about sending my ECU out and they said, $600? Did I miss something somewhere? Thanks.

Joe

 

My guess is the increased interest of the mod. I wonder if there is any difference if you told them you had an SLK. I read somewhere that (I'm pretty sure it was Euro Rev) they don't think to highly of Crossfire owners as clients. Don't quote me on it being Euro rev that said it, I'll do my homework and confirm that statement.

 

Thanks. Keep me posted. I hope no one pissed them off too badly - I want them to do the tuning once the car is turboed too.

Joe

 

Man, if that's true about Euro rev not being happy with crossfire owners, then your better off with Upsolute for $400 at the nearest installer. Or if you want to spend more money and feel better that way, go with Powerchip for $700.

 

Small Note, but My Company ASK Racing, may possibly join forces with an Italian Company, that futures in ECU Upgrades for, Porsche, Ferrari,VW, Smart, Austin Martin, Mini, Maserati, Lamborghini, Fiat etc. If everything can comes together then ASK Racing will be able to offer ECU Upgrades. However I don't know what the costs are ,or will become. I will know hopefully if everything is going to come together by the 25th of this month. So there just maybe another competitor in the world of ECU Upgrades.

 

I believe this statement originates with a comment made by one of the larger PC distributors, namely Evo. A comment was poorly worded and a crossfire owner seemed to take offense to it. I would not read too much into it. I am sure we have all posted something or sent an email that could be interpreted incorrectly. I do not own any of the Evo products nor do I anticipate purchasing their stuff. But thought I would set the record straight.
