Review of the Technosquare L-spec

[QShip]

I'll reveal my stupid mistake that I made with the truck.

With the s/c, there is a valet mode and performance mode. You change them back and forth with a switch. When I picked up the truck, I swore the service manager said that the down position was the performance mode and up was the valet mode. So for months, I was driving it like that.

I went to the dyno and I was almost sick to my stomach!
1) The truck on the dyno in 3rd stopped @ 5350 rpm
2) The truck made 352hp and 392 tq @ 5350 rpm
3) In second, it made 345hp @ 6k

What was going on!? I thought to myself, 'It must be the chip'! That's the only difference between my truck and got_titan's. I talked with got_titan and he asked me if I had it in valet mode or performance mode. I said it has to be in performance mode. I don't know why I was so convinced that it was in performance mode.

Anyway, I figured I’d flip the switch to see what happens. I went to an empty lot and launched it. It felt a lot stronger. But I wasn’t convinced yet. I went back to the spot and shut the truck off. I put it in the mode it had always been in. The tires spun a little and it took off. I went back to same spot , shut it down and flipped the switch again. I launched the truck and it started to go sideways on me!!

Man!! I had the truck in grandma mode all that time! I went back to the dyno after driving it in performance mode and taking the box off my Volant. It made 388hp and 408tq @ 5350 rpm! What is going on!!!???? The TS chip should have no limiter!!!! The dyno guy said it hit some type of limiter. I said how? I had the truck past 6250 rpm on the highway! He said there’s something funny about the chip. I don’t mean HA HA funny. He said he has never seen a chip act like that.

At first I was upset. Why was my truck making such low numbers? But then I looked at the graphs, the hp was still climbing until it hit the limiter. Had the truck made it to 6000 or more, it would have been well over 400hp! It would have dyno’d better with the stock chip! It wasn’t the s/c, it was the TS chip.

I called TS and sent them my graphs. The engineer said there may be another limiter that they were not aware of. I called back after he went to Japan and unfortunately the young lady that answered the phone received the brunt of my irritation. She was not able to answer my questions.

1) Was the program tested?
2) How fast did the truck go?
3) What was changed as a result of the reflash?

After I calmed down, I apologized to her. It wasn’t her fault. She offered to refund my money several times right there on the spot. I said either way, I will have to send the ecu back to be flashed backed to factory specs or for another reflash. I told her that I’ll wait until the engineer gets back from Japan and talk with him.

My thought is, the Stillen ecu and the TS ecu are working against each other at certain rpm. The boost is controlled by the pulley and mapping. For whatever reason, the Stillen unit is overriding the TS ecu for longevity reasons.

The truck hits a limiter @ 110 in performance mode. In valet mode, I backed off @ 120.

I will give Technosquare a chance to fix the problem. If they cannot, I will have the ecu set to factory spec and get a full refund. From there, I’ll get the COBB programmer.

As a result, I cannot recommend the L-spec chip for piggy back systems. I don’t think the chip will disappoint if you do not have a piggy back system. So the verdict is still out on the Technosquare chip for the Titan.

Q - very interesting report and thank you for letting us know. Surely a bummer for having to remove the ECU. It's time consuming and God forbid you break one of those clamps as I did. I have had mine in and out more than a few times. Get a rental and return it since they offered as there are other things coming.

I saw in another post you were looking at powerflows. I was able to data log Toomanymods truck with the powerflows and his truck according to the Cipher was running mid-lower 11's AFR under WOT. I suspect that this is due to the signal modifiers installed. Be sure to watch for his upcoming dyno in the next week or too.

That Titan ecu seems to be a tough cookie to crack completely! I don't know if the ecu is getting overridden by the tcu or the piggyback.

Of course it would be alot easier if I lived near Technosquare but I don't. Connecticut is a long ways from Cali.

The engineer at TS wants me to see if there is a TS sticker on the ecu. If there is, he wants me to tell him what numbers are on it. That will tell him what code was supposed to be used.

It's just frustrating to say the least.

Stillen said they will have a programmer for the n/a guys soon. They also said that they will have one for the boosted guys. Why would the guys running the Sillen s/c need a different one? That leads me to believe that the Stillen ecu is somehow interfering with the TS ecu.

Q-

I'm sorry to read about this. Just as you suspected our piggyback ECU is designed to override the factory ECU. This would mean that it is also going to override technosquare reflash to the factory ECU. We do this for many reasons. We need to make sure that the vital systems of the trucks are only receiving the information that we want them to receive. They are only making the adjustments that we want them to make. For instance we are controlling timing, fuel, air. As well as monitoring all of the systems of the truck as well.

Now onto our computer upgrade for the boosted and n/a guys.

Obviously the chip/programmer/ECU for the supercharged and non-supercharged guys is going to be different. The reason we are designing a different one for the supercharged guys (different than the one that you already have) is because we like to do things in moderation and in strategic stages. Similar to us having a Stage 1 non-intercooled. Stage 2 Intercooled running 6 pounds. And the much anticipated Stage 3 (No I don't know when it will be ready or how much power it will add.) The upgrades that we offer are designed to be done in levels. In life there are always different levels to what people want. Got Titan and QShip seem to be on a never ending ladder and want more, more, more...These are the John Force kinds of guys, they can never have enough power (I'm in this category myself.) Then there are the guys that will get our Stage 2 kit and be completely satisfied with how much power it added and have no need or desire for anymore.

I can't say exactly what our upgrade for the Titan (boosted or n/a) will do yet. Partly because I don't want anything getting out too soon and partly because I'm not entirely sure, my techs won't tell me yet. However, to all the boosted guys I ask that you please try to contain your enthusiasm and wait for us to come out with our kit. That way things of this nature don't happen. Remember, we are the ones tuning everything on the supercharger so we are the only ones that know exactly what will and won't work. I have had a few people tell me that they know who tuned everything for us and that there are companies claiming to be doing our work. This could not be further from the truth. I know for a fact that every single piece of development and R&D was done inside the walls of stillen. We received no outside help from ANY COMPANY. That is why I know that no one will be able to develop a simple chip/ECU that will help you without spending a lot of time with a supercharged vehicle in their posession so they can try to learn what we have done.

You guys are too darned smart!!!!

So how much torque will it add? Can I have one by September 25th? Will the programmer and stage 3 get me into very low 13's or high 12's?

Q - did you send back your TS ECU?

[Toomnymods]

I seriously doubt you'll get into the 12's with just a supercharger and cai, and exhaust.. not with a 5k lb truck anyways :P but 13's should definatly be easily achievable provided you can get traction, so buy some 17" Weld racing wheels for the back and buy 2 slicks for the track and some traction bars and I can guarntee that anything stillen can throw at your truck the slicks should be able to handle..

Not yet. I would like to do some data logging to see if the TB opens the way we want it to open with the TS reflash before I send it back.

Yeah, I know. I wanted to give Kyle a hard time for sabotaging my plans.

Stillen makes chips for N/A Titan's???!!! Well, when did that happen.

It's not out yet.

Excellent product review!!
