TSP Stage 1 Tune for the 2017+ Civic Si (Cobra Race Support Included!)

Has anyone complained about lag with an upgraded intercooler? While the abscence of complaints doesn’t mean there isn’t any lag at all, it’s a pretty good indicator that it isn’t noticeable.

As I understand, the 1.5T tuning logic is a torque-based MAP configuration. In this logic the throttle blade, MAP and boost controller are all used in tandem (with checks to IAT aka post intercooler temps) to create torque. In other words, the ECU targets torque, not boost - this type of tuning logic is a lot more consistent. So, to add to that consistency you ensure that post intercooler temps are consistent.

This all relates to the “fill/lag” time by virtue of the tuning logic. Believe it or not, the ECU is bleeding off boost to keep the turbo from spooling too quickly - see Ktuner ramping options. The ECU is expecting X torque via inputs in X conditions and if the intercooler is larger and fill time is increased, the ECU will either slightly close the throttle or allow a little more boost to achieve X torque under X conditions.

Anecdotally, I can tell you that I never experienced any Knock Retard on my stock FMIC and the TSP Stage 1 tune. I did have a PRL CAI at the time, which likely helped. When I installed my PRL FMIC, I expected a small but noticeable increase in power. My perception was that there was no change at all after the install though.

Don't get me wrong - the upgraded intercooler does what it's supposed to. My IAT2's plummet when stepping down hard, and I never heat soak no matter how many pulls I do. I'm just saying that I don't agree that a FMIC is at the top of the list of "best bang for your buck" upgrades. Honestly, I wouldn't even recommend worrying about getting one until you start noticing Knock Retard climbing, or until you start pushing towards a Stage 2 configuration (upgraded turbo, aggressive Flex Fuel tune, etc.).

I'm running TSP Stage 1 entirely stock except for PRL stage 1 intake and drop in dry filter, my knock control is always .49.

We're in a Honda forum... Driving around in lawnmowers, and with Ktuner it allows them to fly. lol
