excellent write up. Ill get back to you on your question on to why it wont go into superlow. I think its in safety mod, lemme look up how to get it back into reg mode so you can dump to superlow.

Thanks, but I got it to work. Just had to keep my finger on the lower right hand button when turning on the ignition. Then I can select the superlow mode. Just dumped my car and damn, don't think I can get a jack under the car if the compressor fails

Thumbs up

Awesome writeup airtime
Most of the time, these DIY writeup is harder and more time consuming than the
actual installation itself

"Bookmarked!!!"

In all, it took about 40 minutes from start to finish. Didn't really rush it as I was in no hurry. If I had to do it again, I'd say it'll take 20 minutes or so.

I should try and disconnect the lead to the other side. I have already via the controller, turned off the speed function. If this works, it could save some installation time for those new installer.

Oh, no way I can drive in "L" or "9" tried to move the car and the front wheels scraped a bit. "8" was pretty tight but doable. "7" and lower is where its at.

Is this lead the one wire you had to extend yourself? And where does it plugs in, behind the glove box or under the steering wheel?

Yes, this is the extended lead (single wire). It is the blue plug that goes behind the glove box, speed sensor wiring I believe. Under the steering wheel is the active suspension module that has 3 plugs.

Thank you

I am sure you tried pressing the lower left hand button to see if you can access the TEMS menu? No luck?

Still waiting for my buddy to translate the TEMS page to see what I'm doing wrong or not doing.
