‘20 LX to ‘23 Si

[aspitfyr]

I previously had an FC4 (2.0L NA) with pretty much everything possible done to it. It was a great car, but ultimately it was time for a change. I picked up my Aegean Blue Si last Thursday from a dealer 3 hours away…but man, was it worth it.

After 400+ miles of baby treatment, I decided to flash the TSP Stage 1 tune, and it’s yet to take the stupid grin off my face. We caught the clutch slipping in Map 3, as expected, so I’m running Map 2 until I get the RV6 Retro kit installed next week. Car is otherwise stock, for now. Got a few more parts on the way.

My only gripe about this car so far has got to be the idle start/stop feature. I can’t wrap my head around why that would be on a car with a manual transmission.

Get the front wrapped in PPF ASAP if you haven't yet. The paint likes to chip ISANELY easily. I had a few chips in mine in only 2 days before I could get PPF on it.

That must be new, my 2020 Si didn't have that. Can you permanently disable it or have to do it every time? In my Focus you have to disable it every time, but it's less annoying in an automatic maybe.

Unfortunately, I am used to the Honda quality paint. On my FC4 I had the same issue. However, I can’t bring myself to purchase PPF and install it given it’s more than just “slapping it on”, as I’m sure you know.

This is new for the 2022+ models except for the Type R, apparently.
There is a button on the middle console to disable it, but I have to press it every time I start the car, unless I’m driving in Sport mode. Sport mode will disable it, but I don’t wish to drive in Sport mode all the time. I’m not sure if there is a solution via KTuner at this time, but I can’t say I’ve really looked in to it, either. I do know there is a kit you can buy that plugs into the center console and permanently disables the idle start/stop feature, but I haven’t purchased that yet in hopes of KTuner pulling through.

Hmm, that's exactly how it works in my Focus. I hope the ITS doesn't have it.

Ktuner doesn't have a way to fix this. This will solve your problem;

I have it on my SI and my Pilot. Works great so far.

How is the delay, if any? I did see this kit this morning, and it caught my interest.

Do you have to remove any part of the dash on the SI or Sport Touring?

 

[MorrisGray]

Is there not a fuse that you can unplug? I thought I read that somewhere, about disconnecting the system just by unplugging a fuse. ??

Do you mean in relation to installing the idle stopper?

 

[MorrisGray]

Yes, regarding the idle stopper. I went to the web site but the reviews I read were about other models and there were some saying they did it in ten min and others saying more than an hour and had to remove some dash parts? Some saying leads were too short and such, hard to get to and install. Just trying to find out how easy it was for the SI specifically although I don't own one yet, I am interested in buying one if I can find one that is not above msrp.

There is likely a fuse, but I can’t say I’ve explored that yet. Might be on tomorrow’s agenda if I get bored enough.

Most aftermarket kits I’d assume would be just plug and play. The center shifter cover area would have to be removed to access the ports, but that’s all of a 2 minute clip battle. I’m not entirely sure on IdleStopper specifically, though. I have been told by a very reliable source that KTuner is working on a fix for the idle start/stop; let’s hope they pull through so this aftermarket kit isn’t needed. Not a fan of extra wiring unless it’s absolutely necessary.

As for the MSRP, I did shop for my Si for about 2 months and the general markup was 2k-5k over. I was very fortunate to get mine for 2k over, as these cars sell very quickly. I can definitely understand wanting to get it for MSRP.

Little update on the Si. Guess this will be my build thread until I make a proper one. In the past (almost) two weeks, the following have been installed:

- DC Sports Frontpipe + Catback
- RV6 Retro Flywheel w/ Stage 0 Clutch Kit
- Hybrid Racing Shift Linkage Bushings
- PRL High Volume Intake
- Hybrid Racing Shift Knob & Boot Collar

Running TSP’s Stage 1 Tune on Map 3 with no issues. Hoping to get back on the Dyno soon with updated numbers.
