This is by far one of my favorite mods I've done yet, right next to my exhaust system. I waited to get a few thousand miles first before making an opinion, and just to give people a better understanding of my viewpoint ill list my mods
*2017 CIVIC SI SEDAN
-27won Cold air intake
-27won catless downpipe and frontpipe
-Ark performance dt-s exhaust
-Enkei RPF1 18x9.5 wrapped in Federal ss595 with a with of 245
- Clutch masters FX350 with a lightweight flywheel, idk like 10-15 lbs
I'll start with the install. Im 18 with little experience on working with cars other than the bolt-ons I've done so far as listed and just teaching myself. this install is simple enough with watching a video to help. i got it done in 2 or 3 hours, not rushing and taking my time, it could even be done in an hour if you already know what you're doing. After installing you just upload the tune same as TSP stage 1 and you're good to go. I should say that you're gonna need a clutch for this one, there's no way the stock clutch is gonna last. I did all testing around e35 like TSP recommends. I can say that I've heard this tune is quite conservative and safe and with the few thousand miles I've put with this tune that it works extremely well or at least in the cold because I've been using it all winter where it's between 25f - 45f. When it has been dry and my tires are warmed up GOD DOES IT PULL, like i abuse the hell out of this tune shifting last second and bouncing off the limiter and she just keeps pulling. you're gonna need some good tires with it being fwd and with the trq you're gonna make, if you don't have good tires it's not gonna be fun cause you're just gonna spin unless that's your thing. even with my setup, I spin all of first and second but maybe that's because of the cold, third spins if it's not perfectly dry or if I'm going uphill. if anyone is really curious you can easily hit 150mph with this tune but I'm not saying you should lol. ill update this review when autocross season starts but so far I'm loving every bit of this tune.
Hope them dems dont take modding away like they want your guns. She was fast now shes furious. Thx to PRL and TSP for the option to be free and furious. Im now hording e85...
Installing was pretty straight forward, easy to install. But car feels way better. I love how the car feel now.
First off, this is a must have upgrade if are already tuned. The torque is amazing paired with the TSP stage 2 tune; it feels like driving a big go cart in a way. It is a nice power jump from TSP stage 1.
Gas mileage has taken a hit but that is the nature of flex fuel. I used to get an estimated range of ~450 miles but now it's down to ~350 on fill ups (probably the only downside).
I haven't been running the kit/tune for long but it is definitely high quality. I'm still on stock clutch so I'm a little more careful with my hard pulls and I don't do them often. Still no slipping though! 10/10 would recommend if you got flex fuel near you!
Easy to hit track product and fast shipping
Car feel amazing with this kit thanks you two step performance

Why Run Ethanol?
Due to rising gas prices and the push for alternative fuel sources, ethanol, derived primarily from corn, has become a common, cost-effective fuel choice. Ethanol has now found its way into most modern gas stations and the community now understands its list of benefits in comparison to gasoline, such as the fact ethanol burns cleaner, cooler and is more resistant to detonation. Because of these characteristics, ethanol is a cheap alternative to expensive race fuels like race gas and/or methanol, especially with high(er) compression factory turbocharged vehicles.
E85 = 85% Ethanol and 15% Gasoline whereas E30 = 30% Ethanol and 70% Gasoline and so-on.
What is Flex Fuel?
In a nutshell, “flex-fuel” allows an internal combustion engine to flexibly utilize one or more different fuels (usually gasoline blended with either ethanol or methanol fuel), and both fuels are stored in the same common fuel tank. Flex-Fuel systems utilize an ethanol content analyzer to determine the amount of ethanol in a fuel system and a converter to send this reading to the vehicle’s ECU to instantaneously adjust for varying fuel mixtures.
Our Plug ‘n Play Flex-Fuel Kit utilizes factory plugs/outputs under the hood for power and communication to the ECU, meaning no need for additional wiring, cutting, splicing or running wires through the firewall into the cabin! This kit supplies everything needed for a quick and easy installation. Please note that our kit does NOT utilize an ethanol content gauge, as we feel that this is unnecessary. Hondata and KTuner V1.2 both offer Bluetooth capabilities, while the KTuner V2 LCD screen can be used to display ethanol content if desired. All components are ethanol compliant!
