OFFICIAL: What did you do to your Alero today?

[dbral]

Nice head unit! Recently installed one like that in ours. Required a good deal of trimming behind the radio to get it to fit.

Happy to hear your car is back on the road and running well!

I ended up installing a single DIN with the pocket below. I made a bracket to hold a voltmeter and mounted that in the pocket. Only reason I did it this way is because the single DIN was leftover from another car that I junked and I wanted an excuse (and a place) to mount a voltmeter.

Which one did you use? Can you post some pictures of it?

[homegrown]

Sure. Here you go.
I got it from Coverlay Manufacturing.
The fit is decent - although, it would be nice if they also offered a matching airbag cover. Now I just have to see if the upholstery shop can make something that looks halfway decent.
It's pretty clear where the dashcap ends, but it's not in your normal line-of-sight, so it doesn't bother me. New shifter boot coming soon.

I bought one those covers but haven't installed it on my wife's car yet. Looks pretty nice

Installed powder coated caliper brackets. The red matches the hidden struts.

Love it! Should have my drilled and slotted rotors on this week.

What - you didn't like the rusty cast iron caliper anchors?
Looks good.
I miss that car.

Thanks! Post some pictures of your progress when you get a chance

LOL, had these anchors laying around...was going to VHT them satin black until I took a wheel off and and noticed all of the suspension work you did. No wonder the car handles so well.

Matt, if you are ever in the area, feel free to stop by and take it for a spin.

For what it is, it does handle pretty well (especially considering it's on all-seasons).
You should have experienced what it could do with a properly aggressive alignment and sticky rubber (I had it on Bridgestone Potenza RE-01Rs at one point, which were pretty sticky for full-depth street tires).

I'm glad to hear you're enjoying it.

I can only imagine how it would handle with that set-up, but maybe one day the car will at least have a dedicated set of wheels/tires for the track/autocross.
I don't have the guts or the skill to push the car to its limits, esp. on public roads but def. can say that I have not yet approached what it is capable of currently. The car acts like it is on rails compared to one with stock suspension settings.

We are certainly enjoying it and we are still noticing new surprises with it. From the gas charged hood lift struts (I should have picked up on that right away lol) to the giant (and grease-able!) outer tie rod ends, cool things keep popping up. You did one heck of a job building it

Did some tuning and learned some things. With the good advice/knowledge from a coworker that has 20+ years of tuning exp. and our stock GA 3.4 at home to compare things to, I was able to get the Alero running pretty well using HPtuners. Other than properly routing the PCV a few months ago, the change that made the biggest difference was bringing the main VE table back to stock-ish settings (Before and after in pic). This made a HUGE improvement in bottom end power and overall smoothness. The next best change was adding timing in the 400-1200 rpm range and adjusting the TPS voltage/throttle blade angle to match our GA's. This brought IAC counts way up and smoothed the idle with or without A/C on. I set the idle to 975 and that took away the harsh F40 6 speed idle clunking and clanking. It now sounds like a light rumble instead with the clutch out in neutral. The car feels and runs totally different from idle to mid range. It has good bottom end power now and the engine can be lugged at low rpm without issue and no more cold morning 2k idle flare....so far lol.

A weird issue popped up after all of the changes were made. With the A/C off and the clutch depressed the idle intermittently will hunt from 600-1100....but only if the car is moving. Once VSS hits 0 mph, the idle surge goes away. Have yet to figure that issue out. Does anyone know what might be going on there?

As others have mentioned here before, HPtuners does not have many tables unlocked for our cars and it seems that there is a lot of cause and effect going on behind the scenes in the PCM making it even more confusing to me. The Scanner only has a dozen or so parameters to view and log so that does not help. The LS people have all kinds of buttons to push and things to look at lol

Top table is before and bottom is after changing the VE table. Guessing MMS was trying to tune for the PCV they screwed up possibly? The tuner that was helping me just shook his head when he looked at that table.
