Come to think of it, this is precisely what happened. So I guess they were related after all lol.

Does this cause any kind of damage to the car?
Nope. It won't cause damage. But it could be possible that Half-Life pops up on your screen!

Many reasons but here are the main ones.

1. I was always nervous that my clutch was going to start slipping even though I knew in the back of my mind that it wouldn't if driven right.

2. I am cheap, and sometimes I like to alternate between 87 octane and 93 octane, with a tune you are forced to use 93 octane.

3. I had a 3 hour road trip once and during my drive something happened where the tach started to bounce all over the place, even bouncing over red line. It was a very strange situation because I was cruising at about 85 MPH when the tach went haywire. There was no change in speed or even a change in engine sound, just an electronic glitch. I pulled over, shut the engine off for half a minute and turned it back on and everything went back to normal and I continued my trip. Not saying this was the tune's fault, but I convinced myself that somehow they were related.

4. I have always been satisfied with the Si's stock power for what I use it for, a fun daily driver. The tune really was just an experiment, and while the power difference was noticeable, honestly I havent missed it since going back to stock.
Hmmm your gauge cluster started going wonky? Mine was too on hondata until returned to stock.

Interesting.

It's definitely not underrated, that's torque that you feel, something Hondas always lacked.

In perspective, a 200whp/200wtq vehicle with the curb weight of an Si will not do an avg 15sec 1/4 mile.

@gtman just for mental note that is 2 on here that experienced gauge cluster issues while tuned with both brands that were alleviated when returning to stock.

Not a big sample size and still could be coincidence but should be noted.
Seems both of us believe it's from the flashes.

Torque decieves people into believing their car is faster than it really is. The current Si is no faster than the 15 year old 8th gen - I repeatedly ran 14.8-14.9 1/4 miles in my stock 2007 FG2 trapping 94-95mph which can be corroborated with MT's results: https://www.motortrend.com/cars/honda/civic/2017/2017-honda-civic-si-first-drive-review/. Compare those times to MT's 2020 Si review: https://www.motortrend.com/cars/honda/civic/2020/2020-honda-civic-si-sedan-first-test-review/. Supposedly the faster model of the current generation as they shortened the gearing, users on here would have you believe the 2020 Si was going to be noticeably faster. :rolleyes1:

8th and 9th gens on average dynoed around 170-180whp, but the 10th gen is supposedly putting down an extra 20-30whp? :hmm:

I'm in the camp that thinks 0-60 and 1/4 mile times are cool and all but I'm more into real world everyday driving feel. In other words, how does a car respond in traffic and powering out of situations and highway passing power. In most of those real world scenarios this gen Civic Si outperforms the older generations because of that abundant torque. You don't need to wring it all the way out to get into the power.

The older model was actually a bit quicker in real world situations like passing.

8th gen: https://www.motortrend.com/cars/honda/civic/2007/honda-civic-si-sedan-nissan-sentra-se-r-spec-v/

10th gen: https://www.motortrend.com/cars/hon...ndai-elantra-sport-compact-comparison-review/

In everyday driving where you don't want to wring it out to get your power, sure, its the better commuter. That said, this thread is about OP ringing his Si out in 3rd gear against a car known to be faster and claiming the Si to be making 200-205whp because his butt dyno is mistaking torque for horsepower. To put that into perspective, a 205whp Si has the same power to weight ratio as a Mazdaspeed3, a low 14 second car capable of hitting 100mph in the 1/4.

I was tuned and reverted back to stock to burn 87. F that, the car is so much more responsive tuned and gas is so cheap now, i am tuned once again.

I believe what the OP experienced was accidentally holding down the cruise control button, something I accidentally did once while driving and it made me think I broke something

They both need to be downshifted to reach the power band though.

Below 3k they don't feel that different, power-wise. In the mid-range, the 10th clearly crushes the 8th. The biggest difference is that the 8th has to be in the right gear for power, while the 10th can often get away with being a gear high to have access to enough power.


*Assuming stock for stock

That's a stock Si making close to those numbers. Quater mile in 14.502 @ 98.35 MPH :dunno:

If this car has rev hang delete, than in essence it is tuned. Assuming he is tuned with TSP Stage 1 and is using Map 1 (have not watched the video because I'm suppose to be "working"), although it uses factory boost levels, there are some throttle enhancements, so the title of the video is misleading. Just nitpicking :)
