Ignition advance and dwell time on a Denso ECU

[dikidera]

Sorry if this is a dumb question, but what software are you using to interface with the ECU, edit, re-flash?

My own software stack. A combination of Python scripts, SBLs, WinOLS and HxD Hex Editor. and Raspberry Pi

Sorry for delay, life including a new job has gotten in the way. I'm very impressed. Any chance you share / sell your software?

I don't know how to get the "tune" in and out of the ECU without opening it and soldering, which I can do, but it seems inelegant.

I've used a few tuning softwares, mostly "TunerPro" for US cars (Chevy) with good results, although there are many "unknown" entries in the parameters, and that worries me. But that's a different thing altogether. Every mess with TunerPro?

Also late reply, but I didn't get a notification for the thread. I have not used Tuner Pro I just used the Demo version of the latest Win OLS. With the demo version I cannot save my changed files, but not an issue just more of a hassle.

You have an S40 T5 which I think uses Bosch and not denso, the NA version of S40 uses Denso, but the SH7058 variant which is different than my SH7055.
