Re: Tune development

The 150-175 tune is the OEM 175 hp tune. This beta should be more power than that.

The 1.06 and 1.08 have higher peak torque, but hit limits and tend to oscillate in hot weather. I'm looking to find some happy middle ground between 1.08 and this latest beta tune with max torque and no oscillation.

The requests are more balanced with the limits so it doesn't oscillate on and off the limits.

Re: NC2 issues after running basic tune

It's possible that the primary cat was loose already and the pops knocked pieces into the secondary cat. I've only heard of a couple instances of this happening. I put thousands of miles on a cack and pop tune on my MS3 before we released the cracks and pops tunes. I had no issues.

Re: update 1.13.107

The APP Requested Torque table has always only been used in Neutral gear. The name change just clarified that. Since there is no acceleration in neutral, the table values are torque. The per-gear tables are used for each gear. The table values are rate of acceleration. I believe it's meters per seco...

OBDLink SX is now supported!

We are excited to announce that OBDLink SX cables are now supported by all versions of VersaTuner.
Logging and flashing are somewhat slower than VersaLink, but the price point of the OBDLink SX is quite attractive.

OBDLink cables can be purchased at scantool.net

Re: Load and AFR variations on data logs

RX-8s tend to have a lot of fluctuation in AFR. The RX-8 has relatively low flow for such a large MAF tube. There are also spikes and dips when the SSV and APV open and close. The S1 ECU uses a slow processor that can not sample the O2 sensor as fast as modern ECUs. The result is AFRs that are not s...
