Smarty, the new CaTCHER tool.

[Gary - K7GLD]

I have been told and seen recommendations to only run the even programs on the HO,

ACTUALLY, I believe the recommendations regarding the even numbered Smarty programs are not to the HO engine, but relate to those of us also using aftermarket boxes like the Comp that themselves add timing - the recommendation is to avoid subjecting the engine to double timing, which could be hard on it...

Gary is absolutely correct. However, I have seen posts from a few who have used the Smarty timing programs with Coms & found it worked for them.

I absoutely understand the issues around stacking other timing solutions, as that's been discussed in this thread many times before.



I really appreciate the information on longevity reports too, but please understand, I would like to understand from Marco, how he Designed Smarty to work with HO engines. (not the down and dirty details, but the guidelines around the improved timing maps)



Thanks,



Jeff

Marco should be able to answer your question once he leaves the laboratory



He is working hard on the 3rd gen smarty. He should be back online tomorrow.

I agree - there would seem to be enough basic engine differences to warrant some individually tweaked program differences - so the owner of a SO gets the BEST programming to fit his engine, and so does the HO owner.



I wonder if the makers of other downloaders (or even DC, for that matter!) differentiate between programming for the 2 engine types, or simply do a "one size fits all" approach?

Smarty & huffing turbo

I have had the caTCHER and now the Smarty for about 2 yrs. My answer to the huffing turbo is to take the transmission out of OD until you hve obtained speed. You can accelerate very gently with no turbo huff or you can go for it with no turbo huff but almost anything in between works much better if you take the transmission out of OD until you are at about 2500 rpm. Does anyone else use this method?

Nope. Never had any huffing issues except on the 2-3 shift at WOT with Mach 4's. Got a little huff. But that didn't matter if it was with the Catcher or an Edge Comp.

Just got back from a short camping trip over the long weekend, the first pull with the Smarty. All was not well I had the Smarty set on #7 going down to the campground which is only about 65 miles south of me. No long grades just flat freeway. Pulling onto the freeway when the truck would shift from 2nd to 3rd at about 30MPH the turbo would huff badly. This was at about 10 lbs of boost. I thought it was really odd as I could not get the turbo to bark with the truck alone unless I was really on it and had to let off suddenly. I changed the setting to #4 for the trip home, same problem I literally was babying the truck home to keep it from huffing. I can't imagine how this thing is going to act when I get it in some real mountains and have to get on and off the throttle in traffic.

This is not a good thing, I don't want to grenade this turbo.

Marco - Bob, any ideas??

The "huffing" can be caused by the larger exhaust housing you have. It allows the exhaust pressure to decrease faster giving the boost side time to "un-spool" the turbo. The ECM is making higher boost faster now, and the exhaust is not holding up its end of the deal. I've been wrong before but the 16cm housing may be the cluprit. Mike

What do you guys think that the smarty will do for my truck?? Anybody got any opinions on what to do differently other than running just an EDGE drag box?? I'm looking for that little extra fuel and performance.

 

[DLBurns]

OK... is anyone else using a 16 exhaust housing experiencing this problem? Your explanation makes sense in my feeble mind but with all of the users out there someone else has to be running a 16 that can chime in on whether or not they are having the same problem. Short of buying a 14 housing, what is the solution?

I almost always tow with the OD locked out, in this particular circumstance it was in 3rd gear for most of the trip and the huffing occured then.

Since you are holding down the fort Bob, any ideas on why I am having this turbo huffing problem and what I can do to solve it before I grenade my turbo?

 

[pcarlson]

Ok I installed the update today but did not get a chance to drive it anywhere today. I will have to post the results later.



Looking for the same results others are experiencing: 1). Eliminating the flat spot/surge, 2). 3-4 shift and, 3). Turbo bark (Don't want to blow a turbo from software).



Bob/Marco, glad that you took our concerns about the flat spot seriously and promptly put out the fix. That is terrific and speaks volumes of both of you.

Bob,

I received the email notification that you responded to my post but I don't see your response on here?

Can you explain how this might be a transmission issue, I am a little confused by that.

Blair does not have a Smarty but I have asked him to take a look at the posts and see if he has any other ideas.

This huffing has me really concerned, to the point that if it cannot be corrected I may need to get rid of the Smarty

Thanks

[Bob Wagner]

tight torque convertor and large exhaust housing could be your issue. Dave you have been fighting towing issue for a long time.



A stick may be your best bet.

 

[rweis]

The turbo "bark" has been explained and why. Mine "barks" as well, unless I keep the boost about 10 psi until it goes into 4th (O/D locked out) and final gear then you can lay into it.



I have never seen a really good discussion as to what can be done to lessen "bark". A smaller exhaust housing makes sense (keeping up the exhaust drive pressure). What about on the compressor end?, smaller compressor wheels?

I would also shoot a PM direct to piers, I doubt the PDR35 was ever menat to be used with a 16cm housing.



Piers will give you a straight answer
