Reviews for Superchips 3581 Flashcal+ for 07-18 Jeep Wrangler JK

Ease of use

So this is why no one buys AEV Procal anymore. This thing is smarter than me. The features it has for the money is unbeatable. The drive ability of my Jeep is worlds better with factory 4:10 gears and 35s. I can't recommend this product enough.

When it connects, it works great. I was able to recalibrate the speedo for gears and tires. The code reading feature is handy, but you can make modern Jeeps read their codes on the dash board. The idle feature is handy when winching or warming it up in the mornings on cold days. The for the price its great, if it would reliably connect to my phone. I have tried reinstalling the app, and with different phones.

My flashcal+ did not come with a the manual the box says to read before use. I down loaded the app. I did what it said and my phone can not find the flashcal+. I sent Holley two tech support requests from their web site. No response. The web site say tech is open on Saturday. I called, they are not. It is probably a simple fix but with no tech support I will not recommend buy anything from Superchips, or Holley.
