Hi Brian, Yes, you can send the ECU in to reset & remap for your vehicle. The mapping fee is $500 less than new, minus the cost of the ECU.

BMS Stage 2 HPFP has shown 0 improvement over stock on multiple vehicles including their test cars. So if you'd like to run more than E30, you'd need CPI. We only offer full flash ECU tuning solutions. With BEF, you'd have to go through series of revisions, and must adjust JB4 depending on the weather conditions as well. With the full ECU reflash we offer, you don't have to worry about adjusting your JB4 nor rely on the piggyback all the time.

What year & model is your vehicle?

This is a simple ECU swap. All you have to do is disconnect the battery & swap out the ECU, and put the battery back on.

Hi Matthew, The 2015-2018 models share mostly the same powertrain and such, but the ECU & TCU are slightly different. Though, all the mechanical parts are pretty much shared between the LF and face-lifted LF models. 2018-2020 2.0T model ECU tune can be purchased from our site. https://lap3usa.com/product-page/lap3-ecu-tune-optima-2-0t-sonata-2-0t

Hi Trevor, LAP3 ECU Tune will allow you to add the crackle and pop option, and it will sound great with an aftermarket exhaust systems.

Hi, the MPG doesn't really change much, other than if you were to drive differently than before. Methanol only runs when you are boosting over 7psi range. 2gal+ tank usually lasts a month or longer. If you boost a lot, you may have to fill up more often.

Hyundai GDS/Kia KDS scanner system can't pick up any logs of flashing the ECU, as we do not touch your OEM ECU. However, it's important to note that they do consider your boltons or visual mods for blame, and claim you must have tuned the vehicle. While spare ECU tuning option is the safest route of all, the experience highly depends on how the owner brings their vehicle in for warranty/service. Make sure everything is 100% stock visual wise if you are concerned.

There's a lot of customers who have crackle & pop with oem cats. Theoretically, it can wear the cat over time, but we haven't had any customer with cat failure to this day. If you are mindful, and not abuse the pops, you should be fine.

It usually takes about 3-4 weeks from the order date.

All of our tune is made based on custom tuning countless cars on the dyno. Our LAP3 ECU Tune is superior over any custom dyno tunes or canned tunes on the market. The stage is based on what octane you plan on running. If you plan on running 93 octane or higher, then Stage1.5 would be what you need. Stage 2 tune requires 95+ octane as minimum, and that can be achieved by mixing 4gal of E85+93 fill up. If you add a Meth injection system system on top of 93 fuel, it will make well over 95 octane.

Hi Nate, you must get the spare ECU from us. It's a part of the purchase when you buy the tune from us. You will be keeping your factory ECU, so you can go back to stock when you need to.

Have you tried Paypal Credit? That's the only option we have available now as the payment process is thru paypal.

We can, but the power gain is minimal. What we can do is improve the drivability, lean out the fuel mixture a little, and add crackle and pop if you want to add so. You'd have to send the ECU to us for this, and the flash cost would run about ~$450 and ~$650 with crackle and pop.

The LAP3 ECU Reflash module is the best tuning device for the 2011-2015 Optima 2.0T

98RON from AU is perfect for Stage1.5 ECU Tune. It usually takes about 3-4weeks from the order date.

If it comes to rod bearing failure, kia has lifetime warranty on it under recall. So there is that too.

The power output usually varies anywhere from 0-20WHP depending on your fuel quality, weather, elevation, etc. The only modifications we recommend are HKS plugs, LAP3 Stage4 Meth injection kit, and HFC/Catless downpipes. Rest of the bolt-ons make very little to no difference in performance

What year & model is your vehicle? Rebuild would be nice, especially with racing bearings & forged rods & all new OEM components.

You'd flash with Normal button if you want to run the stock tune. If you have 91, then flash with stage1(middle button). If you have 92 and above, you'd flash Stage1.5 (far right button)
