Smarty, the new CaTCHER tool.

Neat.



I can't wait then.

the cr engine has to bleed the rail pressure down after full throttle and before idle or it will over pressure and pop the relief valve. when you lift your foot from the floor the pump gets a signal to stop then the injectors. it is also why the exhaust brake has a delay.

I think I would like to work on the relief valve.



All I really need to be happy with the CR motor is to have the "instant idle" back, whatever that may take.

OK gang:

Just completed a 1900 miles trip to Tampa FL from Cheyenne, WY (I'm in FL now).

Observations:


1) 1st fillup, Smarty on Fuel saver= 19. 9mpg. This was with cruise set at 80 the whole time, and on a 2002 4x4 WITHOUT the CAD up front. Very good, imo. With a CAD or some manual hubs, I'd expect 22mpg. This is on a levelled truck at 80! I'm happy!

2) Second fillup, Smarty on Fuel saver= 20. 4mpg. Overall speed was a little slower (~75mph), but this was a lot more stop-go, and in hilly country (Missouri Ozarks through Birmingham, AL).

3) No mpg for third fillup, as it happened after I was in FL. Yes-- WY to FL on only two fillups (and needle never got below 1/4).

4) Smarty's SW#9 that was too much in Cheyenne (6K elev) is PERFECT in lower elevations. Smoke is a non-issue, and there is ZERO lag-- none!

5) The fuel saver is too much timing for a cold engine with big injectors in high altitude. Lots of white smoke and an occasional stumble, but nothing to be concerned about. Once engine temp comes up even a little bit, performance is good.

6) Fuel saver is pretty aggressive on timing-- you can hear it in the engine. HOs can get away with more timing because of the higher compression. Cruise EGTs with fuel saver are a little lower. Instead of cruising at 8-10psi and 750°, I was at 4-6psi and 650°. This points to better efficiency, imo.

7) Cruise control on the Smarty is much more refined. Even on full Catcher, it will only hit 15psi boost on the CC's 'accel' function. Perfectly manageable and not scary.

8) IMO, the most versatile 24V combo is SMarty/TST/Mach4s and towing twins using stock turbo. This combo will give you instant boost, very low smoke, perfectly controlled EGTs, and decent mpg. It's also good for about ~530hp.

9) The HX35 is out of its range past 31psi or so. I was experimenting while driving, and the engine's note changed RADICALLY past 31psi. Up to that point, all was normal. But the Smarty and 4s will push it to 38psi or so. The last 7 psi is not an options for me. The engine just sounds like it's negotiating with the HG on whether or not to blow. Drive pressure of a stock charger over 31psi is fast outpacing boost.

10) Tampa traffic sucks.

11) I had to disconnect my FP guage-- IT WAS LEAKING INTO THE CAB!!!! Nothing major, but annoying for sure. In case it's not been posted before-- DO NOT USE PLASTIC TUBING AND COMPRESSION FITTINGS FOR YOUR FP GAUGE!

12) new wipers are your friend.

13) Stock clutch still holding...

Justin: What was your MPG prior to smarty at 80 mph in Wyomming; e. g. what is your estimated increase over your previous setup?

 

[Dieselnutz]

Thanks for the update Justin! It eases my mind about EGT's and mileage with a HX35 and M4's. My Smarty and M4's should be here soon! Oo. I am going to try them with the stock HX and then a borrowed 35/40.

Do you have to have a catcher or can you just buy the Smarty? How much and from who and how long. 2001 HO 4x4 QC with mach 3's, 6spd.

All you will need is the Smarty - it duplicates what the CaTCHER did, but with LOTS of neat added levels of programming and other bells and whistles - a VERY neat device!

 

[HeavyHauler]

Well guys I'm on the list! Hopefully I'll have one in 2-3 weeks.



I'm really hoping this will get rid of what I've diagnosed as a surge from my Edge EZ. Marco posted a great explanation of how the CaTCHER eliminates this problem in a thread a while back but I can't find it.



I just read all 24 pages of this thread - now I'm gonna try to find that post of Marco's. If anyone knows the one I'm talking about, please let me know!



EDIT: I found the thread. It's the one about "F1 Mach 4s". Barring bad memory chips in my ECM, this should eliminate the shudder. Now I'm trying to determine if my truck will defuel with the Edge EZ unplugged.

Justin: What was your MPG prior to smarty at 80 mph in Wyomming; e. g. what is your estimated increase over your previous setup?

Last time I had to make an extended 80mph run, I got about 15. 5mpg w/ DD2s and an EZ But this was not an accurate apples-to-apples comparison. OAT was bitter cold, tire pressure was much lower, I had stuff in the bed that caused a lot of aero drag, etc. In other words, it wasn't representative.


So all I can say is that the Smarty gives decent mpg based on how my truck is equipped. If you're looking for me to say that "I got 2mpg more" or "I get 10% better mpg", I'm sorry-- I just can't.

The problem is that I don't use my truck consistently enough to have a good baseline for mileage on the hwy. City, I have a pretty good baseline-- but not hwy.

My hwy runs are always different. Some are on flat terrain, sometimes there's wind (and it blows different directions), tire pressure is often different as I experiment, and sometimes I have stuff in back.

I'm really sorry that I can't quantify hwy mpg effect of the Smarty. All I can tell you is the raw numbers-- you will have to decide what meaning you wish to give to them.

The fact that I can count on 20mpg with a truck this size (and it's poor aerodynamics) at Interstate speeds of 75+ is something I'm *QUITE* happy with.

I'll post about my hwy mpg on the return trip, which sadly isn't until July or so.

I'm curious,, or I don't remember. .



What is the ETA on the '03 - '05 Smarty?



Thanks,

So you're in FL through the WY winter and you're sad about it? What - is Ol' Trail Dog tellin' us some whopper of stories about the great state of Wyoming? :-laf
