We can mask the code from lighting the dash light, but I don't think it will prevent limp mode.

 

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!

 

What calibration ID is on your ECU now?

 

Seems my scan tool doesn't display this. I'll update this post within a month or so once I get everything up and going and can pull the cal ID.

Update: my calibration ID is N3M5EH.
Second Update: I decided to go ahead and use MMP to update now I'm on N3M5EK. Problem solved!

 

We did the first baseline dyno on the shop RX-8. It seems a bit low. We'll go over the car and see if there is anything out of order.

 

Coils, plugs, and wires ordered!

 

Racing Beat REVi intake ordered!
Full TurboXS header + exhaust ordered!

 

seems normal numbers for Mustang dyno? my stock 06 with 74k miles made 165 ish on mustang.

 

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?

 

Remove it 😎

 

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?

 

It would be the same as changing any other parameter. Go to the map or table in Versatuner and change the parameter and flash.

That would assume that you can access it in the first place.

 

thanks hopefully versa will respond. Don’t have much tuning experience.

 

Hi Steve,

I recently (within the last month) bought versatune and registered it to my RX8. That RX8 is... Down for the count at the moment.

I'm buying another RX8, am I able to switch my license over to the new VIN?

 

Quick necro - Is the RX-8 platform still being supported? Any restrictions on the full tuning software since the OP in 2017?

 

It's still supported and no restrictions I'm aware of... I'm using it on my turbo charged rx8
