Another Smarty thread...I don't like it so far

[ASchwartz]

Just got my Smarty today and I've got a really dumb question. What is the difference between software numbers with additional timing and without? I've presently got my truck set to SW1 with the version 3. 07D 1. 02B, which I downloaded this morning. Anyway, if you guys would tell me the difference between additional timing and without, I'd really appreciate it.
Don't beat me up too bad!
Thanks,
Jack

The timing reduces egt's and gives better mileage. For emission purposes the timing is retarded severly and the smarty corrects the problem. If you are running another power enhancement that increases the timing then you would want to run the programs without timing.

Thanks for the reply. I don't have any other power enhancements on my truck, so if I understand you correctly, I should choose a SW with added timing.
Thanks again Avi.

I am running SW3 without the TST right now. I got 22. 6 mpg unloaded, hand calculated.

I've had a chance to play around with 3. 07B, data 3. 02B, key #1 and it is much better in my '05. While the 1-2 shift still isn't quite as crisp as w/ stock programming, it is occuring at a higher rpm - around 1900 to 2000 vs 1200 to 1500 before. I like this alot more. It is more predictable and more comfortable when gently accelerating than the previous 'moderate' tq mgt. programs. The 2-3 shift is much better as well.



For me, 3. 07B, 3. 02B improves drivability while keeping the low-end torque provided by the 'moderate' setting.



Thanks

Which software version are you running to get that? Did you take the truck above 70mph :-laf



Was that mostly highway driving?

When I drove to Louisiana a few weeks ago, I turned the TST off and ran on the same setting and got just 22. 2 mpg hand calculated. With the original software and cruise set at 70.



Very pleased.



Add that to the 13. 4 1/4 mile times with Smarty on 8 and TST on 5/7, and I'm a happy camper.

That is with the moderate smarty with mostly highway driving at 70-75 mph.

I just ran on the dyno today at DDP. DDP 90hp injectors, TST on 3x1, Smarty on #5. The TST has the ooold aggressive program and the Smarty is the old smokey program. Ran 512whp 921wtq. This was at 43psi on stock turbo, stock lift pump and stock G56 clutch with the dually rims still on. I am quite happy.



I also got my best mileage yet on the trip up there and back, 18. 5mpg. Marco and Bob, your Smarty rocks!

Well, my problem is back . After having my TST upgraded and downloading the 303d102b program to my Smarty my truck ran great... (TST 5/3 Smarty/

sw4 EZ/2) for a while... Yesterday, after not driving my truck for a week, I fired it up and drove over to Post Falls, ID. to visit my son.



Timing rattle, which was present even after warm up, but that in itself does not bother me that much. It is the missing, especially in O. D. thats the killer.

I have described this before, but I will try one more time. The feel of the truck having it's fuel intermittently shut off, the sound is just like my oil fired hot water boiler, when I add to much make up air, it blows the flame off the nozzle tip, poof, poof, poof poof poof, poof. That is what my truck is doing!



My truck only has 11,000 miles on it, and I understand that does not mean my CP3 could not be challenged. The CP3 is gear driven so it should not change day to day. For the three weeks prior, my truck loved this combination, yesterday, I had to turn my TST down to 1/0 before it would stop acting off, but you could tell it wanted to.



When I got back home I downloaded my stock program, TST on any setting truck does not miss. I uploaded several different Smarty programs wo/timing and the truck ran fine, if I would add anything over 1/0 with the TST the truck would miss, not so noticable in 1st,2nd, but in 3rd and O. D. at WOT, just awful.



At this point I am about to give up trying to stack these two with any success, but rather keep them separate for their own advantages. Using the Smarty for towing, because of it's low end grunt and low EGT's, and using the TST for everyday driving, for it's on the fly adjustability and top RPM performance (the Smarty seems to drop off at higher rpms).



What would be nice though , would be if Marco would make a program that would allow TQ management w/o any additional changes, that way you could still utilize the ABS feature for speedo recalibration, and us folks having issues stacking could still take full time advantage of both systems.

How about it, Marco / Bob is this a possibility?



I know you both have already went "above and beyond" as far as customer service, and I, along with many others truly appreciate your efforts . Jess

A Smarty program with say sw #1,2,3,4 all progressive levels of torque management without timing or fueling enhancements, and then have sw #5,6,7,8,9, your normal programing w/timing. If a program could be custom tailored to this, then us with compatibility issues could switch between both the TST and Smarty programs with ease and without having to download additional software into Smarty . Just a thought!

I'm sure anythings possible, writing software programs are not cheap.

JJPAGE,



I also have the popping noise. I thought that is the rail being deprived of fuel. My fuel pressure guage shows 5 psi, but the rail pressure guage is low 13,000 psi. This only happens with the stack at higher levels. If I use just the smarty I can drop the fuel pressure to 2-3psi with no adverse effects, i. e. popping. I think that with the increased duration of the PMCR the pressure may be there but the volume of fuel is not there. Not sure if this can be rectified by a bigger fuel line kit or a larger lift pump.
