Thank for the kind words...At the time we were the only ones that were doing any experimentation on the unit and publicizing our resuts...Had we not done so, Turbo XS may have not know there was a software issue to make any corrections.All products have bugs from time to time, especially in newer development. Please tell me what other mid level engine managemet does as much as the UTEC does for the price? Please tell me how many other shops were in constant touch with Turbo XS during the testing phase allowing them to make the needed corrections?Most other shops gave up and sold their customers $500 Boost controllers
.

 

im sure if you would have called or PMed MRC they would have been more than happy to inform you of any extra knowledge they had and why you were having those issues.

actually copied straight from MRC'S post about the subject
"The previouse versions of Software do not work properly and you will NEED to upload UTEC software V 2.8 for this feature to work. Any questions feel free to ask. Once again, another break through from the premier UTEC tuners in the US."

and then MRC, Sharif, and Sam went back and fourth with how the old firmware didnt work and how much time they spent on it. Plus its not like MRC is the only one seeling the solenoid for $100. thats the price range from all vendors plus it has the Turbo XS label on the side, so that makes it 100 time better (sarcasm). its not like he can buy it from them to sell with their product and take a loss on it.

 

I know you work closely with TurboXS, thats great. I just think its 'strange' that you publically annouce that you HAD IT WORKING when the firmware wouldn't support it.

I also know that bugs are a part of any product development, BUT this was a serious bug that would have been simple to catch on a test bench IF the product was thoroughly tested. If they let bugs like this fall through the cracks what else is going to go wrong?

Also, if they arn't going to thorougly test items and verify they work why put them in the instruction manual? I know that quite a few people wasted a LOT of time working on this. I know that I, personally, wasted a lot of time on this because MRC reported that it worked. Had I not read confirmation that someone had it working I wouldn't have spent so long and been so frustrated with it.

My disapointment has nothing to do with the price of the UTEC or the features it offers. Honestly, I love it. However, if they are going to sell an engine management system with X feature for Y dollars they should at least make an attempt to verify that X feature works. When they find that it doesn't work they should make an attempt to let people know it doesn't work. I didn't know the boost controller didn't work until the new firmware was released. I'm guess that they didn't release the new firmware the day they found this bug (I may be wrong there).

Finally, I would hope that TurboXS wouldn't need to be in constant contact with a shop. I would hope that, since they are engineering precision engine controllers that they would have access to the cars and equipment needed to properly verify things work correctly.

 

I realize that he posted the above post. However, MONTHS before that he posted that he had it working with the old firmware. He is contradicting himself. First he says it works on 2.6 and then he says you need 2.8, so which one works?

I have no problems with them charging $100 for a solenoid either, and I know that that is the going rate for the TurboXS solenoid. My problem is that when I asked him about 'fixing' my boost controller his response was to buy a $100 part THAT WOULD NOT EVEN FIX THE PROBLEM. If I recall correctly he even stated the the APS supplied solenoid is a POS. The solenoid had NOTHING to do with the problem, it was the firmware the entire time.

 

What options did the shops have? Bug fixes arn't released over night. These shops had cars clogging up their bays with owners impatiently waiting.

Most shops aren't going to charge a customer to figure something like this out. I'm guessing there were shops 'giving away' countless hours of labor to make this 'feature' work.

I think giving up on a product that doesn't work and purchasing one that does work is a viable alternative in this situation.

 

I think he meant an output to show the M.A.P., not which map he is in.

 

Does anyone know when txs is going to fix the injector scaling?

 

Your problem sounds like it is with me not the UTEC, this is not the first time you posted in this manner towards me. I do not intend to debate you on this topic.I appologize you had issues and feel the way you do.You seem like you are angry, and we will leave it well enough alone, since it appears your point in posting is a NON informative one, with the exception of ripping on me.
Good day.

 

I'm not sure how you feel I am ripping you off, I am only posting on actual things YOU have posted online.

You are right though, my problem is with you and you claiming that the UTEC could do something it simply couldn't. However, I do realize that you are not required to share any information, and the information that you do choose to share may not be at all accurate. So, in reality it is my fault for believing that just because you are a sponsor and just because I purchased a part (or 3) from you that you are an 'expert' on those parts.

I could care less about my wasted time trying to make it work. I enjoy working on my car, and I enjoy problem solving. What really bothers me is the fact that I almost blew my built motor because of the information you gave me and because of this 'little bug' in the UTEC. When you factor in the wasted time with the almost blown motor its just salt on the wound. It further upsets me that you try to play this off as a simple little bug that can be expected with 'new' products. New products should go through a testing phase to prevent this from happening. We're not talking about cheap electronics imported from China here, we're talking about a sophisticated computer management system that could blow a motor up in a matter of seconds. I paid top dollar for a WORKING engine management system. Had I paid a discounted price for beta version I wouldn't complain at all.

 

Once again, I appologize for you feeling this way....however I highly doubt thats what you want to hear.

 

I drove around playing with the open loop boost control today. Iy was cool looking at the log as you can see the UTEC making adjustments to keep the boost at solid level.

I really have no idea what I am doing yet, though. I think I need to increase the boost gain, as the turbo is slower to hot max boost. Kind of cool though, it gets pretty close to the set boost level, and then slowly ramps up to the set level.

 

Jeez, what is the deal with everyone ripping on Julian lately? Not everyone is perfect, but he knows a lot about the UTEC so it would good to keep him on this forum as a resource.

 

Open loop works off of duty cycle, right? So will the boost gain have an effect on it? I can see boost gain changing the way the closed loop control works, but not the open.

I've only ran mine in open loop and it hits max boost very quickly.

 

Perhaps you issue is with the choice of solenoide (GM) it may operate in a different way than the turbo XS one. The turbo XS one is verified to work, I think your the only one running a GM type. There may be a variance in the signal type it needs to see and the way the UTEC controls the solenoid..

 

Its just the trend on here.. You know what they say, "you can please some of the people some of the time, but not all of the people all of the time"

 

I'm not sure what you are saying here. I don't have a problem with mine at all. I was simply stating that mine works great in open loop (builds boost fast and controls how much boost I make).

But, to clearify, open loop = duty cycle, closed loop = desired unitless value, correct?

In open loop (duty cycle) you have no feed back, so I don't think the boost gain will have an effect on boost. In closed loop (unitless value) the boost gain would come in to play as the UTEC is controlling the solenoid using its own logic.

 

Yeah, its been a slow day at work...

Just got done reading the UTEC manual and it states that the 'Boost Gain' will ONLY effect closed loop operation (like I had thought).

Therefore, Quadcam, if you are really using Open Loop boost control the Boost Gain won't change anything. But, from your description it sounds like you are using Closed Loop, in which case this would help you.

 

Oh I meant map as in map pressure from the atmospheric pressure sensor , since if that was possible which it doesn't look like right now, then I could just get rid of my e01 cluttering up my dash.....

 

correct...Closed loop 0-500 values. What turbo system you have and what actuators you using?
Keep in mind in open loop you may have a value of say 60 (representing 60% duty cycle) at 70-100% TP from 2000 rpms-5000 rpms, and you may see a rapid boost climb to say 16 psi, then a slight drop off toward red line. Perhaps try using lower intial values to make a slower spool up and boost climb.

 

Oops! I meant to say "closed loop."
