Launch Control/2-Step Problems

BOLIO 671 · 11-18-2014, 04:07 AM

Spoke to my tuner and did an internet search and could not find any remedies....So hopefully someone on the forum can help me out.....

I took the Z to the drag strip about 2 weeks ago. First time I ran her down the 1/4 mile with the Uprev Tune. I watched the Map Switching Vid on youtube and figured I practice a bit while I had some seat time at the track.

Here is the vid I was sent by my tuner.

Here's my problem. While prestaging at the light I already have the 2 Step/Launch Control map on while holding dwn the Cruise Control Button to switch into my Performance Map. While Prestaging I floor the gas while the 2 Step/Launch Control engages. Once the tree turns green I release the clutch and the cruise control button at the same time as illustrated in the Youtube vid. Everything works great...she gets off the line through 1st and 2nd gear all the way to redline, but once I get her into 3rd gear she suddenly goes into limp mode. I will be flooring the gas but its as though fuel is being cut off for the car to go into safe mode.

The funny thing is when I disabled the Launch Control and just launched off of my performance map by doing the old fashioned feathering of the gas and clutch the Z works fine and shifts throughout the gears without problems. I'm wondering whether anyone else has experience this problem with switching maps using the launch control and what are some of the remedies to this problem

Do you have the .Osiris tune file? If it is not password protected I would like to take a look at the file. If not, only your tuner can fix it.

Yes I have the file..you will be able to take a look at it as long as u have the Uprev ROM editor program.....I have the Tuner model so making adjustments should be simple...PM me ur email and I will send u the ROM file/Tune.

I don't think UpRev has launch control.

^with multiple maps, one can stage with modified say MAP 2 and toggle to MAP 1 when ready.

its a split second.

Yup. That's basically how my turbo anit-lag map works. Switch to anti-lag map, spool up turbo (that map is RPM limited), action map switching to normal map, when it's go time release the cruse toggle and away you go.

I posted proven Dyno numbers over a year ago. That shows ecutek consistently making more power than a Uprev tune.

Those of you who keep thinking UpRev is better are just missing out on a better driving experience.

Sorry,a little off topic,but I'll be looking for a tune once I get my highflow cats and cat back. Was your numbers on a na car or boosted. If na,I might go with Ecu tek. Only problem would be finding a shop in Canada on the west coast. I know there is an uprev tuner near by. Only question is how reputable they are.
Sorry for thread jack.
