TST installed now engine misses '07 MEGA CAB

[stacerbob]

What does it sound like when the rail is getting sucked dry? I havea buddy that has an '04 with the Banks 6 gun, speed loader & a PPE hot, it does not miss & this '07 kinda cuts in & out under moderate throttle, I have torque off & power on 2 & it does it not on 1 Power & torque both on 2 & its pretty bad. Does it need an MP8 for pressure or will the Smarty fix this???

Thanks!

power one is timing only, it has no added fuel. power 2 adds fuel and turns on any torque setting. if you have missing with the added fuel you may have a week fuel transfer pump or clogged fuel filter.

IF you just purchased this box from tst it would have the pressure fooling capability on it, if it is a used box then it may not. You may have something wrong with the box. adding a second box is not going to help.

It says in the instructions "if it has the rail pressure option connect the rail pressure sensor" on the website it says it is not available for the '06 & '07, it came with the rail pressure plugs connected together & this is how I left it. Should it be connected anyway?

 

[d90boy]

I did a search but couldn't find any info on this. I just got a powermax for mine and read the part you referred to on their website. Anyone know why it doesn't work on 06-07 and when there will be a fix for it?

 

[stacerbob]

I have been out playing with it. I have power on 4 torque on 1 or 2 that seems the best. I switched the program to the early twins, full fueling at 12psi. It barely has any smoke, Any time you let the cool down timer run, the truck cranks for nearly 30 seconds before it will restart. If I try to turn the power or torque any higher than this (keeping the combined total lower than 6) It comes on wild, very rough & has that missing or woop woop woop kinda cuts out. I don't know what I am doing wrong but it sure isn't impressive on this truck. Anybody else with an early '07 have one on thats working OK.

you need to hook up the rail pressure sensor on the tst, assuming u have the R49AP? it sounds like you have an auto in the truck they seem to drain the rail easier, Try setting 2 on the rail pressure level, 3-4 power level and 2-3 on the torque, that should be about the most you can run with the stock cp3, watch your rail pressure on the tst if it is dropping below 20K at wide open throttle (after the initial drop) you will get more smoke and higher egts, also a loss in power. if it can't sustain at least 20k turn down the power level. anything above level 2-3 on the rail pressure is to agressive for the stock cp3 and makes the truck surge and run poorly. In the cool down mode the lift pump does not run, a small issue that was overlooked before tst released the new R49, Mark is having a relay wiring kit made that should be available soon to solve this problem. untill then it helps to bump the key once and wait if you let the cool down timer run once you try and start again, but all you can do is crank on it till she starts. I broke a factory turbo on boost level 38, they do not like to be barked if you want the stock turbo to last I wouldn't recommend any setting above 36psi on the boost limit, and try not to let off the throttle abruptly after a wide open run. Installing a larger turbo makes a HUGE difference in sotp and rwhp because you can disable the boost limit and let the fuel flow.

It says on the website the Rail Pressure doesn't work on the '06-'07. Those 2 plugs are hooked together. I did hook it up, it runs terrible! Tap the throttle, it sputters & misses & reves up like there is no control over it.

I just spoke with Marco at Mad Electronics the other day. There isn't a program written for the 07's yet. Likely a reason it's not working right for you.



The computer isn't the same as the earlier 06. I've looked into several different manufacturers and none have even started on the 07 programming yet ( except Marco with the Smarty ) hopefully he'll be done with it soon.



Tried to installed a Viper alarm too but, it ccouldn't be done ... yet. DEI will have the manufacture a interface to work with the new computer first.

 

[stacerbob]

I am using a TST PowerMax, not a smarty. I have one ordered to stack with it. I wrote him earlier in the week & he responded that it does work on the early '07 & he is

working on programming for the new '07.



"The '06 Smarty will work on the '07's also. I'm working on the '07 softwares right now. "



Marco



I wrote him back just to clarify again that it would & gave him the production date from the truck this time.

 

[stacerbob]

I think my running problem is from overboost! It will hit 36 psi in the blink of an eye! I changed to the economy program & it is better there. It won't take full throttle, hits 36+psi quick, thats what is making it defuel! Now what to do!!!

 

[robertyoke]

Do you have gauges on the truck. If so what do the 07 trucks make for stock boost? I would turn the boost setting on the tst up to 40psi and see what happens. maybe you just have a boost sensor that reads a little high from the factory?

All of the above is well and good.



I have lift pump and rail pressure gauges with the rail pressure gauge connected directly to the OEM rail pressure sensor. I have the Superchips FlashPaq set on tow and the Dynomite Diesel Power 50 HP injector nozzles.



The DDP nozzles smoothed out my idle so much, I almost did not care if there was any horsepower increase or not.



Great set up; zero increase in rail pressure, miles per gallon are up, shift points firmed up and can lay down a some smoke if it pleases me.



Seat of the pants horsepower gains will put a smile on your face (the wife even noticed and I promise, she does not care!).

 

[stacerbob]

just has the TST R49 it will hit 36 like nothing I've seen 40 on the gauge. I haven't turned it off to see what it makes stock. I have a Smarty coming for it also. What is the deal with the MP8? If the TST has the ability to turn up the rail pressure why the MP8? Is it the same reason as the Smarty, add some bottom end to it? What about the stock turbo? Ive read here about 36-38 being the limit.

 

[d90boy]

I installed a powermax R49 tonight on a customer's truck. I left the rail pressure connections hooked to each other. Truck ran great, no problem that I could perceive however we did get a CEL to come on. I didn't check the code to see what it was. This is a bit OT but could the cool down functions cause a CEL? I had him turn them both off to see.

 

[stacerbob]

What boost level did you see? It didn't cut out higher up? What year truck?

 

[d90boy]

It was a late 06 truck. I'll ask him tomorrow what boost levels he was seeing but I don't think he's put it above 4/4 and we didn't seem to have a problem.



However on his way home he called and said with the shutdown features turned OFF the truck wouldn't stop running when he turned the key off. He had to turn the temp shutdown on to get it to shut down when he got home. One thing was that none of the wires to the fuse box were labeled but I assume I got them hooked up right

StacerBob:



I had the same symptoms on my late 2006. Talked to TST, they said to unplug the rail pressure. Bad idle went away, but had the same cutting out under hard throttle. I assumed that it was starving for fuel, so I ran only the mild settings. Ran the economy setting for about 30 miles, and threw codes, engine dinger wouldn't quit dinging... .



Long story short, I sent the TST back, and got Smarty for 2006. I am VERY happy with Smarty. It will definately challenge your stock clutch. I love TST products, but the PMCR R49a is not working on my particular truck...



Get the smarty for now, and when TST gets the kinks ironed out, get another one.

 

[olznut]

Do you like it ALOT enough to recommend it to another '06r?

 

[Ross]

Well, I ordered the TST first. That should tell you something. The reasons I would continue to be interested with the TST are the added features (integrated boost, egt, and rail pressure, egt backdown, and turbo cooldown). These features make the TST very cool, but it's just not working on my truck. I've installed them on 2005 and earlier and have great results. They make big power. But, since I've added an external pyro, the Smarty is working for me. It also will make big power, but slightly less than the TST (I think, my opinion, not confirmed by dyno). Plus I think the SMarty is more driveable, especially with the earlier torque management programs. Smarty also leaves no trace, plus it has trouble code diagnosis.

 

[stacerbob]

I too am going to remove the TST & just have the Smarty for now. Drove it today & it felt like the trans blew up! They will push the button on the remote & be sweeping parts up!!
