2012 Steering ECU Retrofit (2010 F)
#76
I drove my friends 2008 ISF with a 2011 ecu, and I cant tell a difference from my 2010.. Didn't try sport mode.

just upgraded to a "42" steering ECU 2013-2014. Just wanted to add my review, like everyone has stated above the turns are shaper, steering is lighter. thats about it... I don't think the steering ecu from my 08 was that much different just felt a little heavier. The install however took a little bit to figure out, I didn't know how to remove the old ECU from the harness until I took a mini screw driver and popped the clip in the middle of two bigger harness' up. (you'll know what I'm talking about if you try to do the install yourself) google was NOT my friend at the time install lol.

I can also vouch that the Figs LCA bushings also does a great job at further improving the steering feel.

You have people who swear the 08 IS F's suspension was like a wooden roller coaster that could rattle teeth out, while some people say it's perfectly fine and quite comfortable. I made mine stiffer, and I'm fine.
You have people who swear they can feel 5 hp from an intake tube, while others feel like they've lost power. I didn't notice a difference.
And here, some people felt a noticeable difference, while others are just like "meh". The latter group is wrong, they just don't know it.
At least with the first and third, this is why it's important for everyone to try and get some seat time in, if possible. Everyone has different sensitivities to this stuff, but at the end of the day, the driver has to enjoy the feel of their own car. Mine is where I want it, and since I interact with the steering 100% of the time, I'd do it again in a heartbeat. The next person? Maybe the opposite, but at least we have the options available.

So nobody knows if the 12 or 13-14 steering computer is better? Someone said the 13-14 made the steering lighter?? I can't see this being possible after reading the turn in is more precise...idk.

Put the 89650-53042 ECU in the car tonight. Definitely better for the wife - she has always complained about how heavy the F's steering is. It also seems to have more boost at low speed. After putting 255's on the front, it was a real chore to move the wheel in parking lot situations. It feels much lighter now, but has not lost its feel once beyond parking lot speeds.
Very happy with the purchase.

My wife, btw who is 95 pounds said she hates driving my 2012 IS-F because the steering is too heavy. Coming from a 335i which had a real heavy planted steering, I missed it a lot when I switched to my IS350 which felt light and almost loose feeling...kinda like an ES350 or something.
That was the first thing that I noticed when I hopped in and test drove my IS-F, the heavy "German" steering feel. It was a very pleasant surprise... It's strange they made steering effort lighter in 2013+...good info to know...

Am I the only one who prefers really heavy steering?
From my brief time driving a 2012, I only noticed minimal difference in sport mode. There was a substantial difference in normal from my car. That said, I would really like to try it on track. Honestly with the stock 2009 unit, I hardly feel any difference in steering between normal and sport modes.
Also FWIW, the LCA bushings did make a noticeable improvement in feel to me.

Redspencer is right with the figs bushings, I can't load to YouTube yet but if your on Instagram (I'm justind2772) and have 2 videos from one run with my little sister, we got it up to 50mph on the initial run and slowed to -10 within feet then sweep around the first set of cones and barrels on a different run (without a ebrake or clutch I was nearly mimicking proam driver chris Johnson's driving in the tech course, ended up getting sponsored by evergreen speedway too! Free admission!) but back to the point, the front end really needs all the figs bushings imo and I need to stiffen the front bar more
