Huh!

I thought it meant the 6. 0's were gonna have to try even harder if they wanna catcher.

I'm up for the challenge, but I'm not sure my clutch is Doug snould have my spare ECM now. Oo. I can hardly wait.

I am very intrested to see some dyno numbers from someone like Bob Wagner who isn't trying to make BIG power, but has what sounds like a good level of power. I like my COMP as mush as the next guy, but this VP is dead, and wonder how many more it will take out. I think the MadEcm would be a great alturnitive.



Will there be any versions that give more fuel, or anything else?

I thought it meant the 6. 0's were gonna have to try even harder if they wanna catcher.

The 6. 0's have some neat tricks coming from this same type of idea, and 7. 3's too. This MadECM is just the tip of the iceburg I hear.

I'll be very surprised if the HP/tq curve on a dyno changes radically with the new ECM programming, because on a dyno, you are in full accelleration mode with EITHER ECM - the difference most are reporting here is throttle response in lighter accellerator applications in normal driving situations - THOSE conditions, as compared with a wide open run MIGHT be quite different, and not be as noticeable on a dyno, all else being equal...



Keep in mind, I am talking about the power CURVE, not the actual power readings.

Can some one answer my Question

Is there other peoplw in the US that can do this???? I have had something that sounds just like this done to my ride. And it is a big difference. The guy was a cummins engeneer and desingned the B series motor. Just wanting to know??????? Justin

Andrew, I am with you and looking for an unbiased shop for torque curves and hp gains.



All I want is fair numbers without any correction factors.



I've had one offer but some of the northwest crowd is balking at the source.



all to be expected with a new product.





Andrew, you will be pleased since you have lost a pump and I have yet the pierce the wire



Thanks for your support

 

[Chipstien]

Hey Bob, Could you PM me where the offer is from and why people are balking at it. Thanks.

 

[RBallard]

For those who have the comp box and haven't or don't plan to pierce the pump wire, I have a nice 2001 EZ I'll trade you!



I have been shopping for ECM's through on-line auto recyclers, seems the going rate is $275-$300.

anyone out their that has one... ... How is the mileage affected? MPG when you are driving normal. Well as normal as it gets for the insane few that can a drive torque monster all day with out unleashing it's furry to the tires

Bob, DDP has a dyno relatively close to sea level. They can make a 1. 00 CF for you.



Torque Freaks down here in Portland can also do the same.



I would really like to see the following dyno runs



1. stock truck stock ECM



2. stock truck stock ECM+ any Timing box of your choosing



3. stock truck w/ MAD ECM



4. stock truck w/ MAD ECM+ any timing box of your choosing



this should provide enough data to answer any and all questions

the "naysayers" may have

 

[Gary - K7GLD]

I second what DF said above!



This new approach will inevitably be compared to other types like the Comp or EZ - even Marco made such a comparison - so getting it all documented with that in mind would be perfect - and then there are those who already have something like the EZ or Comp installed, and will want to know if those can still be used and to what benefit - or danger...

I asked Doug about injection advance & use with the EZ. He told me the MAD CaTCHER advances timeing like the EZ & didn't think there would be anything gained by using them together. Use of the Comp is something different though . I take it then that the MAD program takes care of timeing but a fueling box may be desired by the power junkies.

Marco has said repeatedly that a dyno test is not going to show much of a difference. That the real issue is drivability. his programming spools up the turbo quicker, gives more fuel down in the low RPMs... more punch, faster throttle reaction, etc...



The RPM limiter is not changed, so don't look for more RPM/HP unless you add a box. He has stated that a fueling box + cAtcher will provide awesome performance. I believe his statement was can you spell Faaaaassssssssssssstttttt !!!!!!!!

To put it more exactly, here is what Marco said:



Anyway I doubt that the M. A. D. ECM will show anything special on the dyno. Probably the top numbers shown on a dyno would be in the range of what an EZ does. The CaTCHER is all about driveability and FUN to drive.



I know that sounds confusing... .



What I can tell you about the CaTCHER is more or less what Bob has already said. The torque comes in much sooner, the turbo spools up much sooner...



In other words, and to reinforce my comments as to expected changes in power curves - probably NONE in dyno scenarios, and actual power increase about the same as an EZ...





So now, a lingering question is, is there a significant improvement over what is already obtainable with a Comp - that gives BETTER power gains than an EZ, and at least on mine, greatly improves low end power, throttle response and driveability. The downside for some with the Comp is the potential for VP-44 problems and warranty issues due to wire piercing...



But then, the long-term effect of the MAD is still an unknown as well, and will remain so until a significant number hit the road and the miles pile up...

OK correct me if I'm wrong Marco.

By changing the fueling curve, duration/RPM, haven't you in effect changed the torque curve. If the fuel/air ratio is changed, quicker spool-up, won't the HP curve follow the torque through the power band? I understand the second fueling event provided by comp type boxes, I'm just confused by the claim that you didn't change the upper HP #'s. Fuel added at event cycle would also change the output?????

Don't get me wrong, this is far and above what I was looking for from the EZ and injectors that cooked my transmission.

BTW how do I contact ADT? Mike

Thanks Jared... ... Hows the T-Rex working? Mike

Basically, it sounds like something I've been interested in, albeit, confused about. . . what would it take to make our engines perform like a torque rise engine, similar to what I have in the Kenworth I drive or even my John Deere. Seems like Marco has done exactly that. I could use his ECM conversion and maybe add an Edge later on and have a truck that is strong in performance from bottom to top. Mmmmm, If it sounds to good to be true, it was created by a TDR Member! Where dreams become reality! Very. . . Cool! Ofcourse, I guess I have to atleast wait until my Limo makes it back from the collision center. . . (sniffle). . . (sniffle). . . (snorf). :{ :{ :{ :{ :{ :{
