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

[Marco]

LOL

Yeah, these crazy Italians take off the whole month of August!!

LOL yes that's true. Almost the whole country stops during August. All the major companies are closed for vacation the whole month. That's the reason I'm on vacation in August too. I'm out "only" for three weeks though.



Amillstream, replied to your PM 3

Marco, Sent you a e-mail. My truck is a Texas truck no Californian

 

[darkhorse]

Marco, I believe my truck is a Federal model. I just sent you an e-mail about that.

 

[Marco]

Guys,

Just answered both E-Mails.



Marco

 

[darkhorse]

Thanks Marco. This process seems to be speeding right along.

 

[Murle]

Just to let you guys know here what happen with my new Mad ECM. We have not been trying to hide anything here. Just trying to get it right before we give out the info.



Nothing major. When I installed the MAD and did the throttle calibration I had no throttle response. What I mean was it took 15 sec. for the engine to reach full rpm.



The main problem came from not giving Marco enough info about my truck. I have a 2001 early model. (drum rear brakes) The ECM that I was sent was for a later model 2001. 5. No ones fault. Just that we are all in a learning mode here. Both Doug at ADT and Marco have been super on getting this problem solved.



I will be posting how I like the new ecm as soon as I get it back and installed. Of course it will be by the seat of the pants test just like the FASS. I just hope it does not smell different.



I don't know about some of the other ecm's, but my 3 bolts that held the original ecm must have been put in by the same guy that installed my original oil filter... . I think they had been torqued to 100 fp.

Marco...

I have a core ecm somewhere in the pipeline to you (sent through Rip Rook) but I am confused as to whether you need more info before you flash.



Do we now have to inform you whether our trucks are Federal or California emission?



If so, how do we determine for absolute? My truck is an 01. 5 (rear disc brakes with build date of 1-05-01, automatic trans) The truck was a factory order shipped to Oregon, so I would assume it's a Federal, but if you need to know for certain, how do I find out? in the VIN? or ???



I'm posting this rather than doing a PM because I may not be the only one who wonders about this.



thanks

Murel, my original ECM was torqued on way over sepcs too. Sort of a knuckle buster in there behind all that plumbing.

 

[Marco]

Do we now have to inform you whether our trucks are Federal or California emission?

Yes

If so, how do we determine for absolute?

That is a very good question. From what I know now there are two different ways. The software revision number read out of the original ECM in the truck. That's the best way for me to know which software I have to use



Or the engine certification label ( I think that's the name of the thing). The ECL is on the drivers side of the engine up on the nose of the engine.

Real tight there difficult to read.



There is certified if the engine is Epa or Carb approved.

Epa = Federal

CARB = California



Correct me if I'm wrong. California emissions is not only for the state of California but also for some others.

Anybody knows which?



Thanks,

Marco

 

[darkhorse]

I don't know for sure but I believe some states in the North East have adopted California regulations.

Good that you've told me the exact truck configuration.

The ECM's from Source Automotive ( I assume that's Rip Rook, right?) say all 01 Auto.



I'd understand that as an 01 Early build not as an 01. 5.....



OK, here goes the ECM with 24V-DSL written on it.



Marco

 

[Murle]

Marco, Mine has the CARB. on the tag.

 

[Marco]

Murle, check your PM.



24V-DSL,



Sorry my previous MSG is wrong!



Doug has fwd me an E-Mail yesterday from Rip.

He says 2 rear discs 01's, 1 drum 01... .

So I would have done it right anyway...



Marco

 

[Murle]

Ok guys, If you have the CARB it will have #'s under the CARB label. If you have the Epa there will be numbers under it like 4. 0.

Sorry for the confusion Marco.....



There are two colums on the tag.

Like this:

Epa Carb

Nox 4. 0

PM 0. 10



Numbers under Epa = EPA

Numbers under Carb = Carb

 

[24V-DSL]

Marco...

OK, I just looked under the hood. There are two "tags" on the nose of the engine/drivers side. The writing on both tags is "backwards" facing the firewall, so they're hard to read, but... ... ...





Silver tag on top at an angle on the block. A paragraph of BS, but it starts out "This engine conforms to the US EPA"... blah blah.



Black Tag below the silver tag and is in a verticle location. Wiring harness is kinda in the way. At the top there are two columns, side by side. One says CARB, and there is nothing entered below. Then there is EPA, and below it is a number that looks like 3. 8.



If I've understood the prior posts, it appears that my truck is Federal, as I had suspected.



Agree??



Also, yes, this is from Source Automotive/Rip Rook.



thanks Joe Rainwater 24V-DSL

 

[Murle]

24V-DSL, Yes yours is a Federal

 

[Amianthus]

I've got a couple of things to add to my post above and a few replies.



First off, spoolup IS enhanced. If I drive it right. It's enhanced by at least 200 RPM. But the smoke can be a problem. At least for me. As an example, if I hit it just right, from a rolling start, I can roast the tires in 2nd. Never could do that before. That's pretty good power. I still don't know if I need to keep the EZ or if I can send it down the road. I'll have to wait and see.

Second is the smoke issue. It's still a problem, but as a side benefit, when I stab the throttle while standing still, the smoke is pretty impressive. It's actually kinda entertaining. Bear in mind that I'm kinda wierd that way.



As for the cruise, yes guys, I know all about the restrictor solution for the cruise servo. The cruise seems to be adapting to the new throttle. But it may be a while before it adapts completely. If it ever does. I'll just have to keep an eye on it.



Marco is right, the learning curve is pretty steep with this modified ECM. It's fun to drive(with the touchy new throttle), but one has to try to not be rude with one's exhaust fumes. That's the challenge.



I will keep you guys posted on any new developments with the ECM. Well, only if you want me to.

 

[Marco]

Epa / Carb

At the top there are two columns, side by side.

One says EPA the other says Carb.



The numbers in the EPA column = Federal Engine

The numbers in the CARB column = California



Clear as mud?



Amianthus,



At your age you're supposed to have already learned to drive!



Pleas keep on reporting. You'll see once you get used to the CaTCHER ...



Marco

 

[24V-DSL]

Murle...

thank you for posting the info on how to access the EPA vs. CARB stuff.



What I don't understand is why Marco said in a pretty recent post that mine was done, when at that time, I hadn't responded to the Federal/California issue. Hope he sees my post before shipping, just to be sure.

 

[PRyker]

Marco,



I believe you have my ECM as well. It has my name on it (Phil Ryker). Doug said they went out last week. I just checked and I have the EPA NOX 3. 8 which I believe means that I have a Federal 2002 automatic.



Let me know if you need anything else.



Thanks



Phil
