We were on the dyno finalizing the Stage 2 KTuner flex fuel tune we offer with our Flex Fuel Kit, and the car really laid it down!
Flex Fuel Kit here: https://vittuned.com/civicx-10th-gen-honda-flex-fuel-kit.html
Stage 2 Combo here: https://vittuned.com/prl-ktuner-flash-civic-si-combo-stage-2.html
VitTuned "Stage 1" and "Stage 2" calibrations available for the Si for all customers that purchase the flex kit from us.
We're using:
- KTuner -- the best programmer on the market for the CivicX!
- PRL FP/DP
- PRL CAI
- STOCK intercooler (bet we'll make a few more HP with this thing..)
- Clutchmasters FX400 clutch
A little bit of detail on how our "Stage" based flex fuel tunes work. Since KTuner has the most advanced flex fuel capability on the market at this time -- we not only adjust boost levels based on whether you are in Normal or Sport mode, but we also change boost levels based on ethanol content. This is in addition to the expected fuel & ignition timing changes to increase power as ethanol content goes up. What we used to do by swapping maps -- we've now programmed to ECU to do "on the fly".
So how's this work? Well say you're on pump gas (91-94 octane or whatever). If you're driving around in "normal" peak boost might be around 18psi, hit the "Sport" mode -- now peak boost is around 23psi. Say you add a gallon of ethanol and now end up at E20. Boost will go up a couple psi in each mode (so say 20psi in normal and 25psi in Sport). Now say you want all the power -- and put some ethanol in and end up around 35-40% ethanol content (E40). The ecu will not dynamically make boost level about 23psi in "normal" and over 28psi in "Sport" mode when you just want to send it! This is happening all in the background using our plug and play flex fuel kit as you add ethanol to your fuel.
Now what about E85, Vit? Absolutely and utterly worthless. This is a D/I vehicle. We've gone up to as high as 60% ethanol and there were absolutely no gains over living in the 30-40% area. This has been tested over and over again for the past year now on this car -- it's not any different than ANY OTHER D/I VEHICLE. In fact going from 30 to 40% was only 3hp.... Properly tuned the sweet spot is in the 30-40 area on a D/I motor. Anyone telling you otherwise is very inexperienced! I fully expect this knowledge to trickle down "the channels" and some people are going to act like they just invented the wheel. Just nope. This is just common knowledge that's been in practice for like a decade... we were doing this on D/I Mazdaspeed 3 vehicles years ago... and every D/I vehicle every since. I feel like I'm beating a dead horse by regurgitating this information repeatedly!
So numbers: 295whp/370wtq!!! Stock the car made about 190whp.
