Smarty, the new CaTCHER tool.

... . the idle speed under load is considerably lower... ...



How is this going to effect us guys that back up trailers at an idle over rough ground?

As I noted earlier, the idle speed in my truck has not changed & I am able to climb steep hills in second gear at idle. If, however, you were to be using Smarty & found the idle to low in program #1 for some particular situation, there are 8 other programs to use with normal idle speed.

Lower idle speed is a no no.

This morning it was in the high ten's here, for Italy that is really COLD! Brrr...



I started the engine and as I do usually dropped it into gear after about 30 seconds ( I never let the engine idle to warm up ). The engine stumbles and dies. HUH! What??? Next attempt same result. Whassup????



I pop the hood to have a look at the not so hummin' Cummin' see nothing wrong but notice the smell of raw unburned fuel. I found nothing obvious so I gave it one more try. The engine starts but belches out a lot of grey smoke! OPS... :{



To make a long story short, the cause was the lower idle speed I had set my engine to. I've been testing the idle speed set to 700 Rpm for some time now and did not have any major problems with it. And now that... .



In all evidence, the lower idle speed is not high enough for a complete combustion at those temps.



Fortunatly I had my trusted Smarty with me, loaded up software #9 with stock idle speed and was on my way to the shop. Oo.



Needless to say that at this point I will never release the lower idle to the public. CaTCHER revision 1. 04 here we come...

I guess it's a good thing I never got the lower idle speed when I loaded 1. 03. (did I do something wrong? Smarty says I have 1. 03) It hasn't been that warm here since last year.

I'd guess he's up past his elbows in circuit chips & solder.

Marco and Stefano are busy guys. The assembly has begun Oo.

Do the DTC reader and the speedo recalibration work on trucks other than '98. 5-'02 Cummins? Like a Gas Dodge Ram or Durango? Any Chrysler vehicle with OBDII?

Isn't he in Italy? 8 or 9 hour time difference... . might be sleeping!

Sorry the Smarty S03A as in the picture is for the 98. 5-02 Dodge Cummis diesel

only.

Any ETA when the 3rd Gen. version will be in Beta testing?

 

[WCounts]

Have Marco to send me one. I'll start tomarrow!



With the orders he needs to fill with the 2nd gens it may be a little later than planed.

I'm like every one else. Have money in hand and hate to wait. Some things are worth the wait. Don't spend the money.

 

[Bob Wagner]

the firmware is written and everything is going fine

been trying to follow this thread..... will the SMARTY be able to turn off the 3rd injection (or the 1st, too) event for us CR guys?

I've been following this thread...



Is there anyway on the 3rd gens to get rid of the "run on" when coming off of WOT?



MY Dad's '05 and my customers '06 have a considerable amount of "run-on".



Situation,, From a Dead stop, go WOT for 2-3 seconds, then let off the accelerator to return to idle, and the truck continues to accelerate for ~1 second. I would pay alot of money to the person who could get rid of that, because at higher HP levels, 1 second of run on means alot when it only takes 12 seconds to go 1320 feet.....



Second thought,,,

Any way to put an adjustable Idle RPM?

I was playing with a Crane Cams tuner ona Corvette, and it had several options, one was idle RPM adjustments in 50 RPM from Stock to 300RPM over stock...

Anyway to put an option for low idle, Stock idle, and High idle (~900RPM).







Thanks,

Merrick

I'm waiting patiently for the Smarty, too. I hope it will offer more than the BDDL. On my truck, the difference between "tow" and "extreme" is negligible. I hopefully am going to book a couple hours of dyno time to find out exactly what it's doing.



The only time I've noticed run-on with my truck (yes, I know it's a 6-speed) is when running a pressure box cranked up. I think it's caused by the excessive pressure in the rail.



If running timing/duration only, or a downloader the throttle response is normal.



Do the auto trucks do this stock?

 

[Giachino]

I was under the impressions that the run on is caused by the lack of a blow off valve and it is the turbo unspooling (slowly so as not to damage it)... . on my stock 05, if I punch it from a stop for 10 feet and chop the throttle, it'll do the run on... . if i suddenly release the throttle at speed, no issue.

I hear ya on the run-on issue. Mine takes quit some time to come down from a high rpm even with no load/throttle, etc



Anyway, I am very much looking forward to the Smarty - Theres not alot of people I trust by reputation only, But I will say there are tons of people with his stuff that are happy, so I certainly should give Macro a try!



tick,tick,tick --- it is done yet? :-laf

Actually, it probably is designed that way to PREVENT damage to the turbo, but is not Caused by the turbo. If that were the case, many people would never have the motors come back to idle because of how efficient some of the newer turbos are.



Actually, at speed, you can still notice it as well. Go WOT, and then immediatly to idle, and it will "run on" for 1/2 second.

It is not as noticable, unless you have come directly from a 2nd gen truck, and especially a 12v. If you have put more than 5,000 miles on a 3rd gen, while not driving any other vehicle, it is very hard to notice, but, hop in a 2nd gen and you will see what I'm talking about.



When I get my 3rd gen, and I lift my foot to idle,, I want the truck to idle NOW,, no matter how much barking the turbo's do.

I believe this may have something to do with torque management. Our trucks won't open up instantly either. Marco can fix this. The ECM can be programed to do what we want. Run like a 12V!
