Ok I have a question for the Smarty users.

First I have had many boxes/downloaders and stacks. I was on the first list of Smartys Bob sent out. So I have had a lot of experience with the Smarty and stacking with TST/EZ/Juice/etc.

The thing I have question about is the latest Revo software. With all of the previous Smarty software versions and there have been many, I usually stacked with my TST and EZ. Never had any problems with boost and on the track or with high settings could keep my II SPS66 wastegate open at 55psi for a while. With the new Revo, no matter what levels or settings I don't see over 45psi.

I just had Flux 2s installed a few weeks ago and am going to load the TNT software and tune as high as my modded CP3 will go. So today I unloaded Smarty back to stock, EZ is disconnected for now, set my TST back up to 05tt, 12* Auto Timing (default) and 6/2 setting just to see how it acted with the new injectors. First time I eased into 3/4 throttle good I saw my 50+ psi boost again.

Is it just me or do you higher performance guys see less boost with the new Smarty software?

 

In another thread futher down this page Bob comments that the smarty boost fools to 44psi. Could be your issue, you may need to add a boost fooler.

 

If he has the TST still plugged in the TST should take care of his boost fooling.

 

Yea I expect the TST to do boost fooling even if it is set to 0/0. That is what is confusing me. I did not see this issue with any previous Smarty code no matter what levels on either TST/EZ or Smarty. I could basically hit 55psi on WOT. Now I can again with just the TST, no EZ or Smarty.

 

I kept throwing a low boost code with the Smarty Revo, with older software now loaded I have not seen it since.

 

I know that with lower timing, that will equal lower boost. What settings are you using on the REVO for timing? With the TST on by itself without Smarty on 12* auto, that might be providing enough timing to produce 50+psi.

You might try to load timing #3 which is for aftermarket injectors, or load a even # SW and set your TST to 05TT 12*auto 0/0 and see what happens.

I have noticed that with REVO, my boost comes on slower and tops out around 44psi. Now with TNT I can see 47psi (WG set at this psi), but that is due to the heavy fueling that TNT gives.

 

I have ran 4 and 5 SWs. With 4 I did set my TST timing 12* Auto and usually around 2/1 setting. This was sort of a perfect stack on previous Smartys for daily driving, but could still hit 50psi of boost. The TST will not do any timing control when set to 0/0, only when it is 2/0 or above.

I don't know, maybe just me. I will load the TNT software tomorrow and see what happens. I have read that on 04.5s the TNT and TST do not play well. I will see. Even with just lower TST settings like 2/1 or so I have always gained a fair amount on the top end with the Smarty stack and I would hate to loose that. Maybe I need to plug in the EZ with the TST and see what I can get out of that before I load the TNT software.

 

Sounds to me like the Smarty is not giving you enough timing to make full boost.
Your set-up with the TST kinda makes sense, with smarty on no timing and TST on 12* auto, you get full boost as if the smarty isint there.

Two more things to ask/try...Have you tried to run timing #4 on REVO and no TST???

If that dont work try, timing on #2 (default) and turn the TST on to your normal settings and listen for timing rattle. If no rattle, see how well that works for max boost. Just be sure to pay very close attention for rattle. (Its a killer)

After this, I got nothing.

 

Doesnt' added timing decrease max boost, and retarded timing increases max boost?

 

This has not been my experience. With less timing I see less boost, and with more timing I see more boost.

With less timing, the boost comes on faster but peaks lower. With more timing boost comes on slower, but peaks higher.

 

I'm not sure why that would be.

I know for a fact that increasing timing on a 1st gen will decrease max boost a little. I realize that the 1st gens run static timing and the 3rd gens run variable, but I don't see why it would be any different when you're talking about max boost.

 

I dont know the logic behind it, but I will ask my diesel guru today why this is. On his 24v it is the same way, less timing=less boost.

I will post my results later this afternoon.

 

You are correct.

 

I have the same problem with the smarty revo to with having lower boost but the egt stays in check so I really never worried about. But it always throwing the low boost code on my truck and I have to pull of the road and delete the code if not I have no power.

 

Well tomorrow after I get the stack installed I will be doing a lot of testing with TNT and TST. Today with just TST R49 without rail pressure option truck ran good on 7/2. Basically no smoke unless I really got into throttle and boost hit 50psi easy and 55psi briefly on hard run. I don't even have the EZ plugged in. I love the power of the Smarty, the TQ management, etc. but the REVO software just seems to not work as good as some of the older versions on my truck. But I will find a combo that works for the track and one that works for the street what ever they are.
