Alright. So it's taken me long enough, but look what came in the mail yesterday...
This is a big deal. I've been wanting to go turbo ever since I bought the car, but it's only just now that I do so. This is also in the mail.

AU$175 for this bad boy Chinabay turbo. Just need oil and exhaust hookups. Everything else in the car is ready for it. Fuel. MS2. Trans and diff. I do want to work out some sort of intercooler. It'll be blowing into a pretty tired engine, but I've got another one in the wings.

Good to have you back|, those 510s go for goo $$$ over here as well...
I wonder if a vr38dett would fit >;-)

I don't recall if you can stack maps in MS2e. Want to say yes...

Hello Pete,
Great to see you are making progress! Please keep sharing your build.

There are a few people who've put VG30s in, but not with turbos. Sadly, we live in a Nanny state here. I talked to one guy who fitted a VG20DET. Yep, a 2.0l turbo v6 to his 510. Feels like a lot of work for a 2.0l turbo, but he says it's a great cruiser.

Sent you an email!

Been having issues connecting my new laptop to my bluetooth adapter. It's a windows 11 issue and here's the fix.

Okay, need some tunerstudio nerds... Got my car doing this weird hunt where it almost dies after firing up.
It's not closed-loop. It's just set on warmup then the idle motor turns off.

Are you controlling timing? Or is this a fuel only install?

Yes. Crank trigger and wasted spark with a Microsquirt.

I couldn't see ignition timing on the data log. What is it doing in that zone?

Here's the ign map.
I've redone the datalog too...

I use MAF so not sure if this translates, but I found that adding timing below idle helped to stabilize it.
If you are using PID closed loop idle, I'd guess that your closed loop sensitivity and or proportional gain is a little too high or derivative gain is a little low.
Also, if you are using stepper idle control I found that making a restriction in the line to the stepper valve helped on mine so each step gave a smaller change in idle air flow.
I did go too small at first and had to open the restriction up to find the sweet spot on mine.
YMMV, just my trial-and-error experience so take it for what you paid for it.

Hmmm, interesting.
I'm only using the stepper idle control for warmup. After that, it's just TB position. I live 7km up a hill. Most of my warmups are long and the ECU didn't seem to cope with that. It did odd things with the idle control because it expected the car to warm up faster. So yeah, I had to turn off the closed loop. Which is irritating, because it worked very well on the ACVW setup. When you say restriction, how much are you talking about?

Honestly I do not remember.
Mine is not normal, I modified the Diyautotune custom idle air control body and my 65mm Ford 5L throttle body and cut a gasket and incorporated it directly to the throttle body where the original solenoid style was.








I put a 3/8 NPT plastic allen set screw in one of the holes the barbed fittings goes into and drilled a hole in it.
Then I drilled it bigger until the step size worked good.
