BUILD Five-0’s 86 Notcho

[Mr_Roboto]

What's wrong with the Microsquirt's tune?

 

[Five-0]

It runs great WOT and really nothing I can’t live with per-say. But it’s tuned rich right now and it likes to occasionally die when I’m parking and then start to flood and becomes hard to re-start. Also bucks at low speeds. I wanted to just make it more pleasant to drive and remove the annoyances… and turn it up

 

[Mr_Roboto]

Your cranking PWs may be too high at the higher temperatures.

In terms of the low RPM idle it may be related to your IAC Counts. I will say that there's closed loop idle control in Megasquirt and I disabled it because I fuckin hated it. Your injectors may not be well tuned either, you may need to customize your idle pusle widths to account for dead time.

My issue is I have no idea what the previous owner had anything set to nor do I have any idea how to access that. Then there’s the fact I don’t trust myself enough to tune. I’ll for sure break it lol

 

[Mr_Roboto]

Ill tell you it's a shitton of reading to get where you're tuning and doing it well. You don't have any tune files for it? I could probably take a look.....

 

[Five-0]

I have nothing on the tune. I asked a couple times for any files he may have and never got anything. I don’t even know how to access them or how to plug into the thing.

If you have a serial cable and a serial port you can use Tuner Studio to download the tune from your laptop. BE VERY CAREFUL because you can over write the tune if you click the wrong button.

I may have that in my glovebox, I'll double check. No idea where the port would be. Plus it's been wire tucked so it could literally be anywhere. Chances are I would overwrite the tune. I'm a mechanical engineer, this software stuff is way over my head (But don't tell that to the software business's I'm trying to get into for an industry change ).

how did the oil smell?

how did the oil smell?

Old and well used. It was also low, which I knew. No metallic look to it though so winning!

That's all well and good! Good news is always welcomed! however, I was asking about the teal oil. how did that smell? was it tropical? Passion fruit maybe?

It smelled like Piña colada and hookers

One piece of the puzzle located.

 

[Mr_Roboto]

Should be another piece a DB9 male to DB9 male cable at least with the MS2. Wonder if there's a break out somewhere in the harness? That'd make sense. Look for a shielded cable.

ED:This is the cable, do you see the red/black/orange stub? I believe that would be your break out. There should be an RS-232 to a microphone type cable. This is a version with a USB adapter.

Gotta be behind a kick panel or something. The entire interior is coming out for the heater core and re-dye so I’ll find it

 

[M.Ælex]

Five-0 please report back after you change the oil, i want to know if it smells like crusty nut and expired banana boat after being driven hard.

 

[Five-0]

Started the heater core and dash swap project. Not fun!

Helpers

Mr_Roboto found the rest of it. Passanger kick panel.

This dash has a small crack. I have a non-cracked one I’ll swap in since I’ll be re-dying all the plastics anyways.

Since I have this all apart I’m taking the time to make some cosmetic upgrades and deep cleaning.

I wanted to put a set of pace car trim in. It’s a dark engine turned and reminded me of my old 08 Bullitt dash. It has some wear and small scratches that I can’t fix, but I deep cleaned it, re-did the silver with chrome paint pen, put in new vent foam and felt. I also used the chrome paint pen on the AFR and boost gauge trim ring as they were mismatched originally.
