FTL in Uberdata with A/C switch
 

I've searched for how to turn the FTL on and off with the A/C switch and don't quite understand "grounding B5"

If anyone can clarify, I'd really appreciate it! I'm thinking ground it to the chassis, but I saw on the Uber board that you're supposed to loop it with another wire?

Also, when the A/C switch is pressed in (on), that means the FTL is operational, right?

the last time i did the ac switch thing, which i think is not needed on the newest version... i went B5--->on/off switch-----> ground location.

I have an A/C switch on my dash. The original A/C wiring goes to an area around my passenger side headlight and stops. I removed the rest of the wiring when I removed the rest of the system.

But basically, I need to find out which one of those wires (there's 5) is B5 and then ground it to the chassis? Is that right? ???

sounds right, let me kno if it works

Re: FTL in Uberdata with A/C switch
 

I just ran out to my car to check, My B5 is a blue wire with a red stripe.

HOLY ----... You guys are so much help! Ha ha... ;D

I'll give it a go tonight. I tried it a few nights ago and got tired of revving my engine up to 5,500 RPMs over and over again while I switched the wiring. My neighbors loved it too. ::)

Re: FTL in Uberdata with A/C switch
 

Does anyone have info on how to do this?

I grounded B5 to my chasis and tried every conceivable way to get it to work, and it doesn't work. It does work if I check the FTL/FTS box (all the time), but nothing with the Use A/C box seems to work.

By the way, I'm using 1.7... Maybe there's a bad script in there or something? I also tried 1.8 and that was a disaster.

Re: FTL in Uberdata with A/C switch
 

You're supposed to connect B5 to a switched ground. If it is always grounded then it will be like your a/c switch is always on.

Re: FTL in Uberdata with A/C switch
 

Well, I just read somewhere else that the A/C switch will work, but you have to have the fan on... ;D

WTF?

Re: FTL in Uberdata with A/C switch
 

not to hyjack the tread, but can you enable the FTL with out altering the map?

Re: FTL in Uberdata with A/C switch
 

Yeah, open up your map and go to the Rev Limits tab/page.

If you want it on all the time, set the RPM Launch Cut to whatever you want it to limit at (say, 4,000 RPMS) and the RPM Launch Resume 100 RPM below that. Your RPMs will bounce between the two at WOT at a standstill. Also set the MPH Launch Disable. This is the speed when the Launch Cut shuts off. Anywhere between 5 & 12 is good.

You have to check the FTL/FTS box as well. Make sure all the other values (Shift Cut & Boost Cut) match your rev limit in the upper left hand corner.

Save. Burn. Go!

Re: FTL in Uberdata with A/C switch
 

Your a/c switch will work as wired from the factory. When you turn the switch on, it grounds B5.

My car didn't come with a/c, so I connected a B5 to a switch, then connected the switch to a ground. Now my ecu thinks it is an a/c switch and it will operate my FTL. Hell my idle will even jump up a little bit when I engage it because the car thinks the nonexistant a/c compressor is switching on.

Re: FTL in Uberdata with A/C switch
 

I think I got it...

Blue w/red stripe wire & Yellow w/white stripe wire need to be connected.

FTL/FTS AND A/C boxes need to be checked... BOTH OF THEM.

Re: FTL in Uberdata with A/C switch
 

I never got that ---- to work in my car. I just always left the FTL on. :-\

You also need to have your fan set to 1 for the A/C switch to be active. Tried it out on a number of bins and it works great! I did have it on all the time @ 5,500, but it's a little too high for launching. If I lowered it, then I couldn't do burnouts to warm up the tires... That's why I've wanted to turn it off for burnouts and then engage it at the staging lights.

By the way, I saw a few different posts about having to wire different colored wires together (other than the ones I have listed). If you have the A/C on, fan on and car on, find B5 and start jumping wires. When you find the right combination, you'll notice a change in idle speed. Credit jagojon3 for that one. ;)

Next up, FTS. :P
