Re: Tune development

Absolutely, but the injection quantities we are playing with are already mapped by Mazda as we are not requesting crazy amounts. They are not advancing the timings from 70 to 100 mm3/cycle in the top end area. This can be for several reason, as advancing too much increases Nox. But when I calculated...

Re: Tune development

I had some fun and made plots showing the power and torque estimations of the various tunes, from data collected in various tests. How did I calculate the estimated power and torque? I used the 175 hp tune as point of reference, comparing the injected fuel quantities against the maximum torque at 20...

Re: Tune development

Thanks. Let’s say that I’m happy to help the people here (many shared precious information) but I would not post it online open to everyone. The problem is that my car is a 3 and you have a 6, I cannot just give you the file. Just send me a PM and let’s see what I can do. On the second point, I don’...

Re: Tune development

So, after studying a bit and completing a diesel tuning course I decided to build my own tune. My goals were: - keep maximum torque the same as the 175 hp Mazda tune (420 Nm), to not overstress the internals and the infamous injector seals; - keep driveability at low RPMs the same as stock, to not i...

Re: Tune development

This is the latest version of my tune. I do daily drive it, but still didn't have a chance to test it in really high temps. It feels good and there is a noticeable power increase. https://drive.google.com/file/d/1vNlE7nnRdACeYQvtWh05YOGv8kc6-pTu/view?usp=sharing This link doesn't work anymore, sadl...

Re: Warning Regarding VersaTuner on Macs

Over the last year, we have seen a couple instances of ECUs being bricked when flashing using VersaTuner in a Windows VM on Mac OSX. We have worked with affected customers to recover from the situation, but it usually takes a few days to resolve. VersaTuner does not support running in a virtual mac...
