One thing it will do is help lower egt's in the higher rpms, also Help fuel economy a little bit.
NEVER write an older software revision into an ECM that already contains a newer one. Besides the fact that the customer will loose it's latest update, not only can it screw the trip data. Depending upon what revisions are involved it can even kill the ECM... .
Forgot to post smarty is in and kicks @$$!!!!!! I cannot believe the MPG increase either. I figured the overhead got screwey with the tuner, but hand calculating worked out about right.
I towed my 95 12 valve on a 16' 10K lb rated trailer up to massdiesel on monday and got an average of 16. 4 mpg at 65-70mph. I figure it was around 9K loaded.
Ive in the past only gotten 17 unloaded on the same trip!
Guess the latest flash and added timing really kicks up the MPG.
This is no BS!
Bob or Marco:I'm sorry if this has been explained before but what does the timing do in the odd number levels? The same HP is available in the alternate even levels.
SW # 0 : Half power
SW # 1 : 30 Hp increase, with added timing .
SW # 2 : 60 Hp increase, no added timing.
SW # 3 : 60 Hp increase, with added timing.
SW # 4 : 90 Hp increase, no added timing.
SW # 5 : 90 Hp increase, with added timing.
SW # 6 : 130 Hp increase, no added timing.
SW # 7 : 130 Hp increase, with added timing.
SW # 8 : 170 Hp increase, no added timing. ***
SW # 9 : 170 Hp increase, with added timing. ***
What hp setting?
There are two possible reasons for a different timing after the use of Smarty.
First and most obvious one for the 06's trucks.
The latest update that Smarty leaves in the truck. If you remember, when the first 06's came out a lot of people complained about the bad mileage they got. DC came out with a new SW that fixed the mileage problem. Yet, these new SW's have a considerably higher timing than the older ones. I've noticed that in our test mule also but personally I would not call it " terrible noise". After all it's a diesel...
Second thing that can happen if another brand downloader has been used prior to Smarty in that truck. It's a little bit tricky , I'll try to keep it simple...
Background. In order to keep the key count, trip data and what not intact Smarty reads all those parameters from the ECM and then stores them back into the new software that has to be downloaded into the ECM. OK?
Here it becomes tricky. I have seen it several times by now that the other brand toys screw these data up really bad. They claim to be not traceable but in reality they do their thing just plain out wrong!
Now Smarty reads that data from an older revision SW and writes them into the latest availabel one.
Mind you, Smarty is doing nothing wrong! All he does is to read and then write the key counts and trip data yada yada yada. If those data's are messed up from the beginning... Smarty reads and writes senseless stuff.
Unfortunatly there's no way for Smarty to determine if what he's reading is correct or not!
All kind of strange things can happen in that scenario...
Likely, even strange timing rattles.
There are two ways out of that situation.
1) A reflash by a dealer. DC's tools do not save any data from the ECM before they download new SW's thus they will erase the screwed trip data. (Keep in mind, If a dealer checks the trip data he will see senseless things... )
2) I can do a special software for Smarty that will erase the trip data and update the ECM with a stock SW similar to what the DRB / StarScan would do. Done that several times by now to get rid of the Argentina/ Brazil SW that our competitors have used / are still using. A dealer can not flash those SW's back to a Federal / CARB one even if they wanted to.
Makes any sense?
