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

"Restricted Certification: CARB"



Does that mean it's CARB? Or does that "Restricted" mean it's not approved for CARB?

Finally nailed 400 without a wire tap, low egt's, low smoke and plenty of power.



CaTCHER version 1

F1 MACH 4 injectors

Dodgezilla 40/35 14 wastegated

no wire tap-or any box



Maximum temp +- 1100F

Fuel Pressure A-OK

Boost 30 psi gauge pegged



1st run 399. 2 828. 0



2nd run 401. 4 833. 1





400 was my goal

Nice work Bob!

Those new mach 4's sound very interesting.

More than likely it means that it's CARB. That output is from my Engine Serial Number. I was poking around some more in Quickserve, and there's a lot more places that say my truck is a CARB truck. Plus it was made for me and sent here to California.



I was confused because the data plate had no numbers under both EPA and CARB.

 

[Bob Wagner]

I confirmed with Roger too. no numbers in either box is CARB. My truck is Federal and has the numbers marked in the boxes

FOR THOSE WHO HAVE QUESTIONS ABOUT FUEL MILEAGE WITH THE CATCHER ECM, I HAVE HAD MY CATCHER IN ABOUT 2 WEEKS NOW AND MY MPG'S HAVE GONE FROM 17. 5 TO 18. 5. Oo. JOHN.

 

[Crazygator]

Bob,

Dyno sheet look impressive. Comes on very early and stays there. Thanks for your posting it, cant wait to see mine... ... . :-laf

 

[jrhodes]

I put my catcher in last week and my fuel milage has stayed about the same at 22. 5 around town. Have not done any highway traveling to see if there is any change. My highest MPG on the highway was last June between Bakersfield and Sacramento 29. 8 MPG. Love the low end performance of the ecm. What a kick in the pants

Ecm

Marco,



The stalling issue is just a driveability issue. On the original ECM (stock) when I let out the clutch and begin to engage (motor rpm drops) the engine would increase rpm slightly which prevented engine from stalling. I could do this on level ground with the 14k fifth wheel in tow and not have to increase engine rpm with the throttle pedal. Now, when stopped I let the clutch out and begin to engage and the rpm continues to drop with increased clutch engagement. The rpms do not increase as before. Since I am not used to adding throttle with the pedal to prevent stalling then the rpm drops and finally stalls. Previously I would let the clutch out slowly until engagement began and then the rpm would increase (not much) and then clutch out to full engagement and then press down on pedal to accellerate. This is a gentle take off not a hard power take off.



I can get used to this if necessary but it was a nice feature especially when towing or backing trailer as just gently let clutch out until fully engaged the idle would drop back down unless strain increased. Backing up trailer without slipping clutch.



I don't know what else to say other than there is no idle increase as before.



Thanks for your help!

That does look good! How are the low speed manors with these super sticks. Can you control low speed smoke?

 

[Bob Wagner]

darkhorse, I will be delivering a couple of catchers tomorrow since the next batch is in.



I will let those guys drive my truck and then they can post their opinions





low speed is not and issue unless you have a probem smiling :-laf

You might be greasing the slippery slope.

You might be greasing the slippery slope.

Yup, I just grabbed my toboggan and went head first.

 

[Bob Wagner]

no, these will ne actually geat input. I sent a 99/5sp/fed ecm off one guys truck, then I muffed up and shipped the ecm's to marco.



so I bought a bunch of mopar performance ecm's (brand new) for relashes



so. I found one that match his truck (got lucky)



Talked to him tonight and he said the "mopar ecm" was peppy" compared to the stock ecm.





so when he get the catcher, he cna provide more details.



more info is good













and the other ... ..... details to follow

 

[Marco]

Darkhorse, better Mr. WIMPY injectors! :-laf :-laf



I've told you several times that smoke with "MY" truck is almost none existand to very manageable. Well, my sticks are about the size of what Bob has now in his truck.



So what are you waiting for? You better get one of these sets very soon... Oo.

Bob, that is awsome! Congrats!



Your dynosheet shows a rapid increase in torque/power from 1900rpm up to 2200rpm where it levels off. Is the engine not under full load below 2200rpm, or does the torque really climb that steeply? Your truck is making more than 400ftlbs at 1900rpm, isnt it?

Why not dyno at the lower rpm ranges?



Regards,

Chris

 

[Bob Wagner]

I am VERY pleased with my trucks performance, its fantastic



I have a auto transmission and I don't want to use a mystery switch to force lock up, I have no billet shafts at all.



As a matter of fact this is the first generation DTT upgrade from 2000 when only a TC & VB and clutch pack upgrade was available.



my goal was 400 without a wire tap. can you believe I've gone 4 years and never pierced the wire :-laf now that is self control

... In a move CERTAIN to please many, here's a pic of Bob's latest dyno run, with the new injectors, ECM and turbo mods, as compared to and overlaid upon an earlier one of mine at about 6000 miles on my truck and with the Comp only, set on 5x5:



#ad




The broad blue and green lines are mine, thinner and higher ones are Bob's more heavily modded truck. RPM and torque points are identical for the 2 sheets. The torque curves are nearly identical in shape for both sheets, and HP is very similar as well, with the exception that each scale uses a different scale height for 100 HP points, which make *my* HP APPEAR lots lower than the graph for Bob's run. Both Dynos are Dynojets.



Note where in RPM each engine achieves 400 and then 600 ft lbs of torque in the low RPM ranges, also note that Bob's turbo and injector upgrade delivers LOTS more extension of the power band up at the higher RPM ranges on the right side of the graphs...



NOW for those who will *&^%* and moan about this post, it IS valid to compare dyno sheets of similar cost devices used to increase performance, and as long as I have what I consider appropriate info to post, I *WILL*, no excuses, and those objecting to these can simply skip over them... No apologies!
