Trials and Tribulations of someone new to tuning
 

If this is posted in the wrong section, I'm really sorry. Looking at other threads here, they don't all seem to be cries for help, which makes me think I may be in the wrong place. Either that, or I really am at the bottom of the curve here.

Coming to the end of a 1.8 swap + turbo build.
*FMII no electronics kit
*rx7 460cc injectors
*MSPNP
*Innovate mtx wbo2

Been waiting for my wideband in the mail for the last while, so in it's absence I made sure my car would start and idle. I changed the injectors in the base tune from the stock 220cc to my 460cc, and my car started and idled relatively fine on it's base map. I could smell it was rich, but didn't want to mess with any fuel tables until I had my wideband.

Just installed the wb02 this afternoon, and big surprise, I'm idling pretty rich. So I pull up my fuel table to begin leaning things out. I get the gauge to read a solid 14.5-14.9 at idle. Wonderful. Curious, I start revving the motor into different ranges to see where in my tables I am at what rpm, etc. Typical newb behavior I suppose. Afterwards, the car idles rough and stalls soon after. Concerned, I try to restart the car. Sputters now and then, but no start. Afraid that I'd changed something I shouldn't have, I clicked "undo" until I was completely back at the start, before I attempted to lean out my idle. So now I have a completely base map. Try to start again; same result. Sputtering occasionally, but not starting. I'm attaching a data log of me trying to start the car, along with my current tune (although it should just be a base map right now)

Hoping for some answers, or at least a direction to head in. This is the first project like this I've attempted, so every corner is new to me. Looking at and trying to actively understand these logs is alien to me, so I'm looking to learn.

Also for what it's worth while viewing that log, I haven't tied the wideband into the mspnp yet.

did you make sure to configure MS for the injectors after going back to the base tune?

Yep, re-entered them for 460cc.

Last night after posting here I tried to start her one last time. Started up and idled relatively smooth. Went to sleep thinking that maybe this could all have something to do with the default wue settings, though it seems strange that a base map meant to work in so many different situations would have that kind of problem.

Same problem today. Started the day starting and idling fine, and as the day went on and the engine had a chance to warm up, she's a no go. I'm about to go out and play with the wue settings a bit and see what happens.

Still, this whole experience is starting to feel overwhelming. If paying for a tow and a dyno tune was an option financially at this point, I'd probably be headed in that direction. But still, I really would like to learn this stuff. Maybe it's just a hard road.

Forgive me if there's already one attached, I can't see it since I'm on the mobile app, but if you attach a log of your starts or failed starts we can probably help you more.

Where do you have the map sensor hooked up?

I did attach a log of attempted start, along with my then current tune. No worries though.

The map line tees off of the short line going from the middle of the intake into the fuel pressure regulator. Then through the firewall and into the ms

So, a new issue has popped up. I decided to bite the bullet and buy the upgrade for tuner studio to try to let it "teach me" through autotuning. But now trying to connect to my MS, I get an error saying that settings on my computer and my controller conflict with each other. According to MS, there's a conflict in the tach output. And that's when I notice that the gauge currently reads 65,006 rpm with the car off. Seems like for some reason when I upgraded the program, it got confused on how to read the tach signal. I mean I literally did not even get out of the car, let alone mess with anything that would cause the current tach output to be messed up. Currently trying to google this to figure out which setting needs changed and why.

And one last update. Now it seems like I cannot communicate with the MS at all. Two green lights on on the side of the box, yet the computer screen reads "Not Connected". Laptop acknowledges that there's a viable usb inserted into the same one port I decided to dedicate to megasquirt use, but Tuner Studio isn't seeing something.

There must be fixes to all of these things, but it really feels like any and all electronics are disintegrating around me.

(EDIT) Yep, com port test failed. Currently installing drivers to use a different usb port.
(EDIT EDIT) Using a different usb port did nothing. All connections are solid. Fresh out of ideas.
