Is running both a Smarty and the Quadzilla Boost fooler a bad thing?

I just read the Smarty does boost fooling.. If that's the case would running the Quadzilla boost fooler AND the Smarty be causing an over boost to fuel condition, or boost pressures that are to high?

I will remove it for now...

Feedback?

Thanks!

I don't think it will hurt anything.
Many people stack performance boxes like the EZ and MP-8 that has boost fooling with the SMARTY without any issues.

I run both with a EZ and I have not seen a problem yet. I run about 45lbs of boost, and the boostfooler keeps egts down about 200 degrees.

 

The EZ does not do boost fooling, I am not sure about the MP8.

 

Last time I check the EZ did boost fooling. A least mine did.

Maybe for the pre 04.5?

I know mine doesnt though.

 

Fellow BOMBers,

I feel there is quiet some confusion about the " Boost Fooling " on the CR trucks. Let me try to explain exactly what's involved with it.

Let's start from the 2003 to 2004 trucks.
Those trucks use a "traditional" wastegate. With traditional I mean to say, apply enough pressure to the actuator and the WG opens. All mechanical...

For those trucks my SW's actually already do the " boost fooling". That means, there is a table of values in the ECM that commands fuel based upon intake pressure. So much pressure, so much fuel. If the pressure exceeds a preset value in that table then the ECM will cut back on fuel. That's already taken care of with my SW's.
2003's to 2004's are a no brainer. No need for an electronic boost fooler. You need to "fool" with the wastegate actuator in order to see higher boost.

The 2004.5 and up trucks.
In addition to the above they have an electronic valve to provide pressure to the WG actuator ( It's that black gizmo screwed into the turbo with the rubber line to the WG actuator ). That valve is controlled by the ECM and it's actuation is based upon... you guessed it the intake pressure.

In addition to the boost table discussed above there's a second table that deals with the duty cycle of that valve VS boost. At a certain preset point the valve opens, provides pressure to the WG actuator and the WG is opened.

That is the "problem".

The WG actuation is based upon the boost pressure, the MAP sensor.

Let's say for a moment Smarty is used on a truck ALONE. OK, I can mod the table that deals with the duty cycle, thus open the WG at a higher boost pressure.

Now we stack Smarty with the modified duty cycle table AND any box that does "boost fooling". (Almost all boxes fool the ECM into seeing less boost than there is in reality.)

What do we get?

Smarty's SW opens the WG at higher than stock boost pressure. PLUS the box fools the ECM into seeing less pressure. That translates into even more boost before the ECM will open the WG. Whatever is the weakest link in the chain will go BOOM....

See?

That's what has held me back from relasing the "Boost Fooling" SW's for the 04.5's and up . The Boost Fooling software's are ready. I'm still debating with myself if I should send them to customers upon request or publish them on our website ready for download.

Upon request is a problem because the file is hugh ( 20+ Megs ). Published on the web site is even worse. I can already hear it..."you didn't tell me that I would have blown my turbo with that SW"...

Thought's?

"That's what has held me back from releasing the "Boost Fooling" SW's for the 04.5's and up . The Boost Fooling software's are ready."

SO back to my question .. Can/Should I leave the boost fooler on safely with the SW that you have now? (the latest on your site) Then take it OFF after you release and I install the new 20+ meg SW.

You did not answer my question. It appears it is OK as is now but not later (if I D/L the new 20 mg SW) is that correct?

Thanks John

 

Im running the Smarty with Quad's boost fooler on my 06 and love it. I try to keep it limited to low 40's but i can and have hit 45. 973604x4 said he hit 48 psi for a month with his stock turbo and it held up fine. From what i understand, the 04.5-06 turbos are some tough ones.

 

If you published it on the web site with the appropriate description....something like

Smarty S-06A Ver. 4.03A, Data: 2.04A
Mild torque management increase (Standard Smarty software)
Boost Fooling Added
****DO NOT STACK with other devices that add Boost Fooling****

....I think you'd be fine. People tend to ask questions here and at TDR if they're unsure....and if they dont understand the above and still do it, can't see how thats any more your fault than the guys running level 9 on a stock tranny! :-)

I'd love it if you could send me the 06 boost fooling file....I dont have a stack and that would save me $ not having to buy the Quad Boost Fooler...please let me know... jgiachino@msn.com...p.s. I can also provide an ftp link if thats easier to transfer the large file.

 

Smarty doesnt change the boost on the 06's (current smarty software), so your only getting additional boost from the quad boost fooler....hence, not an issue other than running increased boost thru your stock turbo isnt enhancing it's life expectancy any....
