Engine/Transmission (1998.5 - 2002) caTCHER ecm (Marco's aka MAD)

[Marco]

Kevin,



I'm not able to understand which ECM of those I have here is yours.

I've contacted Doug but have not yet heard back from him. I will contact you ASAP.



It could be that you've got the wrong file for your truck but only if you provided a wrong describtion of your truck...



Your truck is a 2001. 5 ( with rear discs??) Automatic, Federal or Carb?



For the "incompatibility" of the CaTCHER with the Comp. That has to do with the HP gain at high Rpm, certainly not with limp mode. Limp mode you shouldn't get! Are you SURE that your problem is not Comp related?



Code # 237 is MAP sensor voltage too low. The Comp plays with the MAP sensor signal, not the ECM... .



Let me know if I can help you!



Marco

Every 2001 ecm that I have received have worked perfect, so there is no issue with the 2001 reflash as long as the ecm is sent to marco with the right information

Bob,

Just recived and answered an E-Mail form you.



Did you receive my answer?

nope nada nothing, maybe a message in a bottle might be more reliable. :-laf

Marco,

Doug told me he sent out my Stock ECM back to you last week some time. I wrote a little note describing my problems and put it in the box and Doug said he would see to it that you would get it. My truck is a 2001. 5 (with rear discs??) Automatic, Federal. That is what the back of the MAD ECM said also. I though I had a bad Edge comp so I sent it in and they sent me a brand new comp and wire harness, so I doubt it's the comp. As the 237 code I spent $94 and put a new MAP sensor in it to see if that was the problem, still does it. What do you mean--(or the "incompatibility" of the CaTCHER with the Comp. That has to do with the HP gain at high Rpm certainly not with limp mode. Limp mode you shouldn't get! ) Are you saying that the comp gives to much HP gain and confusing the ECM? If I disconnect both battery cables on both batteries and touch the positive and neg together to reset the ECM and put the battery cables back on I get the wait to start light back, the lift pump charge on key on, and the torque converter hunting goes away.

At what RPM should the MAD ECM kick in??? AT 1750rpm it is like turning on the comp on level 2, but under 1750rpms it feels stock. When accelerating I moves pretty good but when the transmission shifts in to 4th gear and the torque converter locks up it feels like Iam going to hit the windshield, (acts like its defueling). When it shifts into 4th gear and lockup the rpms are about 1200-1400 rpms. I really hope we can get this figured out... Let me know what else you want me to try...

silverram323,



The behaviour of the CaTCHER you're teeling us is NOT normal.

Anyway I'm thinking that you have a problem(s) somewhere with your truck.



For example, code #0237 is MAP sensor voltage is too low.

Now the CaTCHER uses the inputs in different ways than a stock file but it does NOT alter the input levels.



Dunno if that's clear? I mean, for a given output from the MAP the CaTCHER can output more fuel. The CaTCHER does not deal with the high/low limits of the inputs ( sensors ).



So when you set code #0237 with the CaTCHER then you will set the same code with an original ECM.



All that taken for granted that the ECM you're using now has no hardware problems... which has happened before... . :{



Could you do a simple test? Try the truck without the Comp...



Thanks,

Marco

 

[Marco]

Sorry,

It's Sunday morning... .

I've just re read all your problems, the above MSG isn't answer enough.

. I was wondering your ecm can make the torque converter lock and unlock, lock unlock and so on. It's doing it from 35 mph to 60 mph

The torque converter ( transmission ) is controlled by the PCM not the ECM so nope the CaTCHER SOFTWARE has nothing to do with that problem.

That problem could be caused by a defective ECM.

Did you recieve my stock ECM from doug yet?

Doug sez he has send it. Now that I'm thinking about it... There was an ECM in a Box... I think that's yours. I'll tell you tomorrow morning!

Are you saying that the comp gives to much HP gain and confusing the ECM?

Nope, we're working on a "problem" with the CaTCHER+Comp on trucks with BIG injectors. It seems that a few trucks are getting less Hp ( top ) with the combination of the CaTCHER and the Comp. That's probably a timing problem. Has nothing to do with the problems you're having.

At what RPM should the MAD ECM kick in???

Well exactly like everybody here sez. You should feel it from idle up. The best part is the sooner torque/Hp/spool up... .



I hope to have addressed all your problems & doubt's now...

The truck I drove with this brain in it, "kicked in" at about 1700 RPM starting from a 1500 rpm WOT run. This was in 3rd gear with the convertor locked.



Power was linear from 1700-3000 rpm, but not awe inspiring.

 

[silverram323]

Marco, I am driving the truck without the comp since I have put the MAD ECM in. Soon as I plug the Map sensor and data link connecters in and go for a drive the little yellow engine light comes on and the truck won’t have power. I can't get the EGT's above 800 degrees at WOT. After about 1-2 weeks I loose the wait to start light and the lift pump will not charge when the key is turned on. If I disconnect both battery cables on both batteries and touch the positive and neg together to reset the ECM and put the battery cables back on I get the wait to start light back, and the lift pump charges when key is turned on. The manufacture date on my truck is 6/01 so it should be a 2001. 5. Are you going to reflash my stocker ECM to the (MAD) and send it back so I can try that or is there something else you want me to try???

I don't know if I understand you rigth...

You're saying that you get the codes when you plug in the Comp?

Well, I'll look into the brain of your ECM. Then I will know what version-year-modell your truck is. The only test I can immagine right now to get a correct answer would be to test the ECM you're using now in a different truck...

If the problems move with the ECM = Bad ECM. If not the problem is somewhere in your truck.



I'll let you know tomorrow what I find out from your ECM.

Kevin

put it on a ScanTool, and go from there.



Cycling the Key does not get all the codes in the PCM/ECM.

 

[Marco]

Kevin,



I HAVE your ECM!

I've read the SW version #. It's a 2001 BR/BE Automatic Federal Cummins Cold. That's the version for the extreme cold climates running fuel #1.



I'll CaTCHERize it now. If you want it fast, shoot me an PM with your address I'll send it to you direct without going through Doug. You could have it within 3 days.

Is linear a good thing???????

Is linear a good thing???????

I was wondering about that too... ... must be the redneck in me wondering about again. . :-laf



ON a side note/question, for those of you that have the CaTCHER installed, what is the smoke like? Is there smoke on demand or can there be smoke on demand? LIke a set of Bully Dog 2's or less? Just kind of curious if you can black out an intersection or just haze it over? Or does it matter how you get into the throttle and not really smoke at all? Thanks

 

[RCone]

Is there smoke on demand or can there be smoke on demand?

Yes! Jus kiddin. You can have it both ways. With the CaTCHER and larger injectors than stock, and maybe even stock I suppose, if you don't roll into the throttle you will smoke. But, with the CaTCHER that is what you want to do anyhow. You don't have to stab the throttle to get the mass moving, so yes, you have to re-learn on how to drive your truck. Smoke is not a good thing anymore, IMHO, unless you are in a competition setting.

Roger

Roger has it right. I'm running Don's Mach 1. 5's ( Marco calls them wimpy) Stabbing the throttle makes a dark black cloud. In rapid acceleration, I get a thin gray haze, otherwise it's clear as clean hot air.

 

[Diesel Freak]

heh heh linear=uneventfull

 

[darkhorse]

Geez, Diesel Freak, I'm not at all sure what's an awesome event to you but I haven't heard to many complaints from CaTCHER owners. It's sure a better mouse trap in my daily driver than the EZ I once used. I'm not knoking the EZ either. It worked well, but the CaTCHER workes noticably better for me.

 

[RCone]

heh heh linear=uneventfull

But linear is a good thing if the power good, and is nice and consistent from the starting point to the top most point. That means it is predicatable and smooth doesn't it?

BINGO! Ya got it Roger!



darkhorse, I am used to driving a different truck than the one I drove with the Catcher.



The truck I drove was a 2002 Auto with a HX35 hybrid, F-1 M2. 4's and a PEC (the road test was done with the PEC off, and on levels 1x3, and 1x5)



My daily Driver is a 2001 HO with a HX40, F-1 M4's and an Edge EZ (plus a three wire Blue Box for those times I really need it)



Needless to say, my truck pulls much harder than the test truck. This is without the fueling boxes on either truck turned on.





If both trucks had their respective fueling boxes turned all they way up... well, we would need to bet another two-bits!
