Hi all wanted to put my Spark and AFR map up for review for anyone to browse and let me know if it's relatively safe or if there are any adjustments to improve. I think I have it most of the way there but, just wanting a second opinion.
Car is a 1.6 stock motor with a supermiata intake, raceland headers, no cat w/ racing beat midpipe and power pulse muffler.
I’d sa you’re about 2 degrees advanced from 2600 and up, and too rich in the cruise region of the afr map, should be right around 14.7 from 3000ish to 4500ish.
Not a lot to look at without the tune attached. It’s otherwise a good start, and if your AFRs match the targets, you’re 80% there. Only other thing I’d say is if you ever plan on going turbo, why not set the boosted row AFRs to reasonable values? Or get rid of them.

I uploaded the tune. I didn't put in your changes yet but, that's what I had last time. but, regardless sounds good. I'm glad to hear it's a nicely setup so far. I'll mess with the boosted rows down the line. my plan is to stay N/A for a bit.
1.6 and a bunch of US based parts makes me think you're in the US, but maybe this is an NB? If it is, it makes sense why you're MAF based. If this is a US 90's 1.6, switch to speed density under engine and sequential settings, that's the biggest issue I see outside of what I've said above.
Also, lower your rev limit to 7200 instead of 7700, your engine state settings look off (throttle closed should be 1-2, not 5), AE is basically off, put sequential injection high on your list of mods to do, tune your initial value table once it's idling stable, and tune your EGO. That's a start.

I will when I got the car and the ECU it was from an autocross car and I suspect somewhere along the way that they had to make the ECU class legal hence why it's running MAF instead of MAP. Why the sequential injection ? I don't mind researching a bit more but, don't know much about it. Was there anything wrong with the EGO in there ? I know a little about tuning but, a point in the right direction will normally get me started.
