Re: Tune development

Hi, Anyone still here? Would either mk or p4nzer be willing to share their tunes with me? I haven’t bought the software yet as I haven’t heard great things about the 1.08 map. Thanks I've stopped with tune development. Unfortunately I wasn't able to get rid of the oscillations, so I'm back at 175 t...

Re: Tune development

Wow nice, I'm still waiting for my cable. I live in tropical country with hot and wet weather all year round, average 29 to 30 degrees temps What's worse can happen if I use this tune?

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.

Re: Tune development

Cheers for the tune, have downloaded and flashed it this evening. How were the egt's with this tune, any chance you post a link to download the logs so I can study them? Also how did the changes you made with the O2 tables affect how the tune behaved? I didn't change factory EGT limit, my max value...

Re: Tune development

Looks like the new update includes: Added new exhaust O2 limit tables for Mazda 3 diesel, will this let the tune run richer ? Anyone know ? I worked with VersaTune guys on identifying and testing those O2 tables. Modifying those tables allowed me to create tune with peak power of 200HP at 4000 RPM....

What does "Injection Limit - Acel/Decel Maybe" do?

I'm trying to make new tune for SkyActive-D that won't have issues that current tunes have (fuel cutoff). By looking at logs of existing tunes, I've noticed that for all of them max amount of fuel is ~103mm^3/cycle, even though values in all limit tables are higher, and ECU should request more fuel....

Re: Tune development

Another curve, Stage 1 Performance, Torque Limit Per Gear is mistaken, it's table named TREV_OFS_REVCTL_D and it is in RPM not Nm. X values are marked GEARP_REV, which seems to be gear, but from name and units it looks like some offset in RPM. When you say "Stage 1 Performance", do you re...

Re: Tune development

I've been running 175 tune for some time now, but I miss beta tune, it's so much better :( I've tried 1.06 also, but improvement over 175 wasn't very noticeable, as it's with beta tune, so I went back to 175. I found this video, where they had same EGT problem as does beta tune. I understand there a...
