Speeduino Tune Check
Hello all!
After 2 weeks of reading guides and questions on here I decided it was finally time to actually post/ask a question.
So a bit about the car first -
92 1.6 Manual Eunos
ECU - DIYEFI built Speeduino
Bosch IAT
AEM UEGO AFR Gauge
Toyota Coil on Plugs
HKS Manifold - Decat - Home Made rear section
Cone airfilter
I have attached my tune and my most recent log file. (tune was slightly changed after the log was taken) Would you be able to take a look and see if there is any thing I have blatently screwed up?
I know I need to sort my acceleration enrichment as doing a test on the way home gave me hesitation / mis fire.
The Spark table is what I am most interested in getting corrected. I understand to a certain extent the AFR table and will use that to sort the VE table.
Thanks in advance !

Your required fuel seems lean. Plugging in 1600cc engine, 212cc injectors, I get 12.7ms required fuel. Yours was 11.7ms. What am I missing? Are your injectors slightly larger?
Your Acceleration Enrichment settings are all centered around TPS. It is my understanding that the 1993 doesn't have a proper TPS to work with that feature. According to the log, the TPS is mostly at 100% and then kinda floats between 0-8%. This tells me that you have the "dumb" TPS. This will not work with that AE strategy. I recommend that you look into upgrading as it makes a huge difference in ease of tuning the AE.
Your trigger angle in the "Trigger Settings" section is listed as "0." Did you follow the instructions on https://wiki.speeduino.com/en/decoders/4G63 to find your actual trigger angle? This is very important to make sure your spark table is commanding the correct spark timing.
That's all I have for the moment.

With regards to the trigger angle I was told by various people that this wasn't needed as I had verified my timing using the lock timing function and a timing light.
The required fuel is left as it was stock so I'll look into that once I get home 🙂 thank you so far though !

This is stating 230cc but 212 at 3 bar.

I'd probably run a little richer up at 190KPA - closer to 11.5. You're not going to give up anything material on power or economy as you're flat out but you will gain safety margin. I have run the same sort of AFRs as you without issue on UK 98/99 RON but have added a margin because there is no major downside. You shouldnt borewash at 11.5 target if accurately hitting it.
You timing is a little more aggressive than my 10:1 1.8 VVT at top end but probably looks in correct ballpark for lower compression ratio 1.6 - others will have experience. I always use knock equipment to check, or to calibrate your ecu knock detection and optimise timing on dyno - I wouldnt look to optimise through forum advice as any number of things could mean your base timing and dynamic timing is not the same as the next persons.
