I have a few questions and figured this may be a good place to ask since it may help others instead of emailing them directly to you guys.
1) I have a 2004 RX8 and with Versatuner loaded. I only see 2 Fuel Enrichment maps and 2 Air Fuel Ratio maps, not 3 like your post shows. Is this correct or is something messed up in my case?
2) The Desired Air Fuel Ratio logging parameter seems to correlate to nothing tangible... During closed loop it seems close to what the Actual Air Fuel Ratio is, but does not match either of the 2 Air Fuel Ratio maps I can see, in open loop it varies wildly settling in the .995+ lambda range with seemingly no effect on the Actual Air Fuel Ratio. So my question is, what exactly is the Desired Air Fuel Ratio logging parameter?
3) The Air Fuel Ratio Base number is referred to from the Closed Loop Air Fuel Addition table, which seems like it should be stoich if we are basing closed loop fueling off of it, but in my experimenting it seems to have no effect at either cruise or WOT. What does this value affect?
I have some more questions, but I think those answers would clear a lot of the other odd behavior up as well. I admit this is my first venture with flash tuning setups, so some of my questions may be noob-ish, I'm just used to standalone setups where I have the full equation at my disposal and it's simple to figure out what each table is contributing and affecting.
will you be adding cranking fuel enrichment and timing, to help with E85 cold start. I converted to e85 and having issues with cold start since it's getting colder out.
thanks,
I plan on purchasing Versatuner and have a quick question. My car has not had the MSP16 flash performed and I would like this update. I was reading Versatuner works with the latest "base map" or "software version" and was wondering if the MSP16 flash would be made redundant by using Versatuner? Thanks!

We launched support for ND Miata recently which took a lot of resources. We are working with some RX-8 testers on a performance tune and are also working on sourcing a test RX-8 for the shop to speed up the development process.
Since the VFAD is based off vacuum it appears you should be able to tune the car to open the VFAD earlier. Is this possible? Can anybody else shine some light on this as well?

I’d rather not. What research do you have that says I should remove it and what for in exchange. I think Mazda did an ok job with it. I just want it to open earlier. Seems like its can be able to be done by tuning right? if so can I do it with VersaTuner and how?
It's basically to reduce intake noise and doesn't really do much else.
The solenoid that controls it is controlled by the ECU so I am sure that is can be accessed by Versatuner
That’s what I was thinking too. I just feel the CAIs and mods to VFAD are all inadequate and all within the margin of error. So why change. Mazda’s engineers and research is prob more adequate than companies or people doing a CAI or mod that can only prove a horse power or two. I feel if that VFAD can be tuned to open earlier it could gain the same amount of tiny if any gain (or loss) that you would get out of CAI or mod.
How would this be accomplished with the VersaTuner?
