OFT launch control inop.
 

Hey guys. Just got my OFT in the mail, finally. Opened it up and flashed with the stage 2 UEL tune, and it seems like it's livened up the engine so I'd assume the flash worked, but launch control isn't activating. I even flashed it again just to make sure. I've searched and searched, but haven't seen any other issues like this.

Anyone else have issues with it?
Car is a limited 6MT with just a Tomei UEL and muffler delete.
Thanks

What is your calibration ID? Some don't suoport LC yet.

ZA1JB01C

That CAL ID does support Launch control and flat foot shift. How are you trying to activate it?

TCS/Stability control off, clutch in, 1st gear, throttle all the way open.

oft rom set LC at about 5800 rpm unless you mod it see links below

are you using the 2.062 tunes or the old 1.5x tunes ??

Where would I be able to check?
Hardware version is 0100, and software is 0132. Not sure if these are at all related to the tunes, though
File in ECU: Stage2 UEL B01C.bin

if you using the preloaded tunes on oft its hard to tell easily.

if its only a couple of months old it probably v2 tunes but older than that it maybe v1.5 x

probably best to go to the oft download site and download the V2.062 tunes and definition files just to be sure, always use the definitions that come with the tune download for editing.

@shifter907 please post here what you find out. I also just installed my OFT on Friday and have not been able to get these 2 items working yet. (Received Friday, purchased directly from open flash website, so I assume it has the v2 tunes on it already)

THIS

If you don't have NLS or FFS working on your OFT tune and you have a CAL ID that supports these features, it is likely that the tunes that get auto-generated by the OFT were created before those features where released. To run the latest and greatest maps, it's always advisable to download the most current map folder from the website and manually upload the desired tune. I have confirmed that all the v2.062 B01C tune files all have FFS and LC enabled :)

Sweet, I appreciate it guys. I'll let you know what happens when I finish with everything.

I got a question on the launch control. Do you have to engage the clutch and put in first gear to active the launch control? I ask because, when i step on my throttler without engaging the clutch, its still active my launch control.I don't know if it suppose to do that?

Stupid question from me; how do I upload the new 2.062 maps to the tablet? Installed openflash manager, but I and see where or how to upload them.

Not a stupid question at all. Just connect your OFT to your laptop and run OpenFlash Manager software with a WIFI connection. After your OFT gets all the latest updates, go to UPLOADs. You will see 5 memory slots already filled with the OTS tune files that your OFT auto-generated when you installed it. Just delete one (click the red X next to it), then in its place, select the desired map from the OTS map folder that you downloaded. After that, click START at the bottom of the screen. When complete, disconnect from laptop and connect to car. Go to TUNING->WRITE and then select the new map and follow prompts from there. Pretty simple!

Just as long as your vehicle speed is below 6mph and your clutch is depressed, the engine will rev to it's secondary rev limit (launch control RPM). This is independent of which gear is selected.

Ok but I did not press my clutch and it's still active. Would this have to do with my adjustment on my clutch/clutch sensor?

I too received a pack recently and quite likely flashed with older auto generated 93 oct tune on mostly stock car. I will at some point likely look to update firmware on unit and fresher tune definitions so this post helps. I'm easily satisfied with improved in town drivability and look forward to letting it sip corn juice

The clutch pedal has to be depressed to engage LC or FSS. However, the clutch switch is right at the top of pedal travel so even just resting your foot on the clutch pedal can sometimes be enough to activate it.

Awesome. I'm glad you are enjoying the OFT :)

Ok thanks I will have to readjust the clutch switch.

Thanks so much guys, it worked just fine! You're the man, Shiv.
ECU seems kind of sluggish compared to how aggressive it was earlier. Just means I have to go let it all relearn again.

If the engine feels sluggish after the re flash it is likely because you didn't let it idle for long enough after the flash. If you start driving it too soon, VVT will be disabled for a period of time. It will come back online soon but it's always better to flash and the wait until idle drops to <900rpm before driving off.

Gotcha. I'll see how it goes in the morning

@Shiv@Openflash,

When i put in neutral and just rev (foot are not on the clutch),its seem like it its won't go pass my launch control RPM. Does this mean the LC is active? As you mention on your previous post, it must engage the clutch to able active the LC.

Sorry for so many questions. Just trying to figure it out.

I have noticed the same behavior, except with no clutch the RPM is 400 less than the LC setpoint. More info here: http://www.ft86club.com/forums/showt...59#post2051759

similar to my issues:

sumarized:
The first, is launch control. I currently have it set at 4k rpm, and set to disable at 10mph. If I am stopped in the car, with the car in neutral (not pushing on the clutch) and I step on the gas (wot), it goes straight to 4k and sits there...which is what it should do, however, it does this whether or not I am stepping on the clutch-I though LC should only be enabled when full throttle AND stepping on the clutch. The only potential issue here (I think) is that I can't be cool and rev to 7k while in neutral. Pretty minor issue. However, when I'm cruising on the highway (going, say 60pmh) and I step on the clutch and floor it, the rpm's go to 5k(which it should, since the way launch control is configured in the computer by redline (minus) XXXX)-but, I'm going over 10mph, so why did it engage?. Again, while on the highway If I dont step on the clutch, and I floor it, the car will rev to 7k. SOOO...Isn't this supposed to be the way the car/rpm's respond when I'm stopped-and not on the highway? When I'm stopped or below 10mph, it should allow me to rev to 7k, unless I am stepping on the clutch, and then it should go to whatever my preset launch rpm is, and if I'm going over 10mph, it shouldn't engage at all.

I think on the highway with clutch in your engaging the flat foot shift rpm limit.

lc is independant of clutch , and disabled over 6 mph

ffs is enabled whenever you have clutch in, i think it set to 5600 ie delta 2000 , if you want to get rid of it set ffs delta to zero '0'

does the D00C have LC/FFS yet?

It's suppose to come out here soon, not sure how soon though. :iono:

sweet and thanks for the respond bro

Can anyone confirm if the CAL ZA1JF20P is configured for LC?

I am using OFM 1.27.0
The XML files that came along with the OTS V2.076 and RomRaider V3. In RomRaider I've set the limit for 7600-3100=4500 LC and the LC Disable speed at 15mph.

I upload to the car and test the LC but the rev's just shoot straight past 4500rpm.

Ideas anyone?

Cheers

Eeeek, when you edited the rom in romraider were the boxes for parameters Green with numbers already in them or black with nothing or weird characters.


See the romraider tips link below

Hi Steve99

Originally the fields were black with no apparent data or weird characters. I entered the data to the 2 fields and saved the bin file. I also exited the bin file, reloaded the bin file and checked the LC fields, on rechecking the fields are green with the LC settings that I had entered.

Upload to OFT and then to the car.

LOL, just read your RomRaider Tips and Tricks...Certainly haven't bricked my ecu! Yet!

Thanks I'll upload the last bin file, just in case.

Thanks.

Nick

In relation to the patch I'll have to chase this up with Shiv?

ahah,
yeah your lucky mate the original lc/ffs patch put where the ecu checksum was so if you did what you did it blatted the checksum and ecu stopped cold as it thought the checksum was bad. luckly the new patch sits in a different spot, but yourself a lotto ticket ;-)
