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
*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.
