Default UTEC over an Ecutek

Launch Control Mode - It's not a code. I bet it only happens when you push the clutch in. If not it means you have launch control enabled and no clutch switch installed.

Loads of people run a UTEC over an EcuTek flash.

^^^^^^^^^
nope that's not it. It's throwing the code in the boost column and it's just around 4300 - 4400 rpms when the it's switch between the open and closed looped fueling. The UTEC has the launch control mode off and has even been reflashed. The Ecutek right at that point in the rpm band takes over timing and won't let the UTEC have it.

Post a UTEC log then.

Does it look like this?

Code:
 6653 +15.8 4.1 104  70    00   W/B  +18.6   65.5 +20.0  -0.5 320.00 4.1  11.30
 6775 +15.8 4.2 104  70    00   W/B  +18.8   65.9 +20.0  -0.5 320.00 4.1  11.37
 6802 +15.6 4.1 104  70    00   W/B  +18.8   64.9 +20.0  +0.3 320.00 4.1  11.48
 7002 +15.4 4.1 105  70    00   W/B  +18.8   68.1 +20.0  +0.5 LCM. 4.1  11.52
 6071 +15.4 4.0 105  70    00   W/B  +17.7   54.2 +18.9  -1.5 LCM. 3.9  14.92
 5564 +15.4 4.0 104  70    00   W/B  +10.9   57.5 +18.0  -1.5 320.00 4.0  >25:1
 5564 +16.5 4.1 105  80    00   W/B   +9.4   60.6 +18.0  -1.3 320.00 4.0  14.92
Or like this:

Code:
 6653 +15.8 4.1 104  70    00   W/B  +18.6   65.5 ECU  -0.5 ECU 4.1  11.30
 6775 +15.8 4.2 104  70    00   W/B  +18.8   65.9 ECU  -0.5 ECU 4.1  11.37
 6802 +15.6 4.1 104  70    00   W/B  +18.8   64.9 ECU  +0.3 ECU 4.1  11.48
 7002 +15.4 4.1 105  70    00   W/B  +18.8   68.1 ECU  +0.5 LCM.   4.1  11.52
 6071 +15.4 4.0 105  70    00   W/B  +17.7   54.2 ECU  -1.5 LCM.   3.9  14.92
 5564 +15.4 4.0 104  70    00   W/B  +10.9   57.5 ECU  -1.5 ECU 4.0  >25:1
 5564 +16.5 4.1 105  80    00   W/B   +9.4   60.6 ECU  -1.3 ECU 4.0  14.92

LCM = Launch Control Mode. LCM is on even in switch position 0.

Something is screwy if you are sure LCM is off. What is the switch position?

FYI - I have been running an EcuTek under my UTEC for many years, no issues.

Did you pass the correct boost signal around the Utec? I have been running the Utec over Street Tuner for ~8 months. The first thing I noticed was that even on Utec map0 the boost signal was changed. To correct this I had to jump the MAP signal line from the input of the Utec to the input of the stock ECU, and cut the conection for the MAP between the Utec and ECU. This lets the stock ECU "see" the correct MAP level.

I just ignored the boost. ECU is mainly MAF based and I used TurboXS DTEC for boost control. I did re-calibrate the ECU and UTEC to read the 4.5 bar MAP sensor that I am using. I did this for the ECU a while back when I was running with the UTEC uninstalled and was testing the ECU boost control capabilities.

Talking GET THE Ecutek!!!!

The Ecutek is the best thing out there! I had a UTEC and it was good but, you have more control over the stock ecu with the ECUTEK. You cannot go wrong with tuning the stock ECU when you have the capabilities to do so. The Utec is good but your still fooling the stock ecu. Let the ecu be tuned and be more safe by using the stock ecu. Trust me...I gained over 30 whp by changing to an Ecutek.

i was about to do that myself.... i called ecutek since i got a crappy tune (which cost me 520$) and my car knocks terribly in high 4 at WOT and all of 5th... timing was advanced to high so im most likely gonna sell my VF30 once i get my GT-12 on.

I've been drinking this evening so I will respond to this, I usually would not.

The UTEC is not fooling the ECU at all, please take a little more time and read up on actually how the UTEC works. The UTEC runs as a piggy back when it's letting the stock ecu control the engine then completly takes over control of both timing, fuel and boost of you want it to. No fooling going on.

gcm05's issue is a strange one. Without logs or at least him posting UTEC parameters and stuff like that we may never be able to help.

If this is true you didn't have a good tune on the UTEC. Properly tuned all EM will yield approximately the same results.

To the OP: You really need to drive around and log what is going on so we can see it in action.
