This isn’t an accurate comparison.
Lap3 you can get a spare ECU while RaceChip is a piggyback.
It is accurate, as Lap3 offers both a piggyback unit and tuned ecu
It’s not an accurate comparison because the RaceChip is not intended to compete with custom programmable systems (piggyback or spare ECU). In both cases with the Lap 3 you are getting customized tunes.
The more apples to apples comparison would be Lap3 or JB4, both offer custom programmable tunes based on mods and utilize CAN data from the OBDII whereas the RaceChip is primarily intended for stock vehicles looking to maximize the existing hardware and is an analog setup.
Burger Tuning (JB4) has a lengthy track record of tuning vehicles as well and has a well established cult like following for German vehicles.
I would suggest that if that’s the route you’re going down to reach out to Burger as well. You don’t necessarily have to ask them to compare themselves to Lap3, that’s a fruitless endeavor — as each vendor is going to advocate for themselves, but you can ask if certain feature offered by Lap3 are also offered by Burger.
I would be wrong if I didn’t also mention that if you do not plan on upgrading/swapping parts, upgrading the turbo, etc. and you like the ability to quickly (i.e. within 5 mins) remove all traces of the tune/piggyback with no traces both of those options would be overkill. If you are looking for a kick in the pants while keeping everything else stockish then the RaceChip is more than adequate and self-contained to the engine bay.
There are options for everyone depending on just how far down the rabbit hole you’re willing to go. For me, the ES is my fall and winter ride. Come mid-March or early-April it’s going into storage until late-October. I do not plan on doing any upgrades to it. I just wanted something that upped the power a little while allowing me to turn it off and pull it out quickly for stealership visits. The RaceChip offers just that. I am not the only user here that has one. Both of our experiences have been positive.
Choose what will work best for your situation and the direction you plan on taking your ride. At the end of the day, I doubt you can make a “wrong” choice with any of them.
