I got the kit installed and the car seems to be running fine except for the occassional stall when i stop at a red light. I was going to update the firmware on the Ultimate to 1.14, but I seem to be missing the CD that was suppossed to have come with the Turbo Kit. Does anyone have any idea where I can get another copy; perhaps download it. I kept everything in the kit together. Thanks for any help anyone is able to render.

Regards,

Glad to hear its working for someone. Did you have to do any tuning, or was it pretty much ok out the box?

mikeschaefer

ehh I thought the Ultimate wasn't even supposed to work with our cars if it wasn't at least 1.14, meaning I think you already are on 1.14

www.mohdparts.com has all the software revisions for download, the kit is not supposed to come with a CD

sillybastard, for reference what flash are you on? mysql is post-R flash and he's the only other one I know that is using the kit w/ ultimate out of the box w/o tuning. Just trying to get a feel for the tuning GReddy did to the unit as it is shipped

sillybastard

I did not have to do any tuning at all. It seems to be working descently out of the box. The only isues I have experience is when I stop at a red light it will stall after hitting 4-5K rpm right before. Sometimes it goes to 0 rpm and almost dies, then recovers, but not always.

Silly, what is your AFR at idle? Are you using your AC when it stalls?

You might be able to use the Anti Engine Stall and/or Idle Adjustment Maps to fix this problem but it depends on whether or not you can get to them without loosing the preloaded Maps. The way the upgrade kit ships some of the maps are locked. These 2 maps are unlocked but I don't know if you will be able to change them without loosing the preloaded Maps.

You don't want to "upgrade" it to 1.14, that's going backwards and removes some of the rx-8 specific changes that you're going to need.

Within the next week or two we should be seeing a non beta release of 2.0 firmware, which you should just hold out for if you can. The firmware update will not fix the issues you're seeing - you'll have to overwrite your locked map with an unlocked map.

And as others have said, the stalling can be fixed with the anti-stall map.

Search for threads that I've started, one of them goes into a bunch of issues I've had with the Ultimate - almost all of my issues were either tuning based, due to vacuum leaks, or because I had the standard Ultimate and not the upgrade kit ultimate (which has an RX-8 ignition chip).

Once my issues were worked out, it turns out the car really does run well on the Ultimate as it comes shipped with the turbo (or upgrade kit) without modifications.

I'm running a bit too lean due to the midpipe/catback that I have installed. So I'm staying off boost in high rpm till the new firmware comes out.

sillybastard

According to Greddy, the Ultimate is suppossed to come wih a software CD that not oly has the USB drivers to support the Ultimate, but also includes the GUI interface.

I have no way to tell what flash version is on the Ultimate since, as mentioed above, the laptop don't know how to communicate with the Ultimate. I took the car car to a Ttunng specialist and he did not want to attempt it as he has no experience with Rotary engines; honest guy. Sadly I am in Atlanta at my buddies house as we installed it together and I do not know anyone here to help out with tuning. I have visited that website last night and didn't see the the software needed to impliment the flash updates unfortunately. Perhaps I missed it and will look again now. Thanks for trying to help bro.

you can get all the Ultimate firmware/software from mohdparts.com

Mohd also had the 2.0beta software up for download, but was asked by GReddy to remove it since it was not yet ready for public consumption.

If you really want the beta software, they were also posted on the ultimate yahoo group. But I don't think it's worth messing with. Stuff like coolant temp readings is broken, so you'll be unable to use auto tune... which is what I'm dying to try out

sillybastard

Actually now that you menton it, yes it only stalls whe the A/C is running. I know I need to have an A/F gauge just to keep an eye on things and one is inbound to me, but not installed yet. Right ow I have the Greddy RS BOV and autometer Boost gauge, so I am running the bare minimums ATM. I wll be putting the AFR and EGT gauges on as wel in the near future. My issues are very minor compared to hat culd have been going wrong, so I am pretty pleased. However, the Obsessive Compulsiveness I have in me, want everything as perfect as humanly possible LOL. I thank my late wife for that trait as it was hers util she passed ROFL.

It is running extremely rich as I went from about lows 20MPG to lke 8-10mpg. Thankfully gas prices are a little cheaper, so it don't stng that much.

sillybastard

Thanks for the awesome info! I will just suck it up for now and wait for the 2.0 release. I had read about the beta on thse forums, and as you have reccommended; I had already decided to not install it till it was released. My issues are minor and not worth creating more serious issues IMO.

Is this RX-8 Ignition chip already built into it, or do I have to purchase this? It is not exibiting the typical vacuum leak idling rough issues that I would expect to see, so I don't think I have one. However i wil make sure I am not loosing vacuum somewhere just to eliminate that as a possible issue.

Thanks again for all the help! You guys ROCK on this forum!

My fuel consumption went up as well, but increase fuel use doesn't mean your car is running safe afr's through the entire range. Since like you, I'm running the stock locked Ultimate, I can tell you at the lower boost range it's doing high 10's, mid 11's, then as I go into the higher rpms it starts going above 12 and into 13s.

I think it's due to my exhaust setup, but you may find the numbers similar, so you should be careful till you have a wideband installed..


You can't buy it. I don't think anyone besides GReddy even knows what it does right now. It is only available in the new turbo kits that come with the Ultimate or the RX-8 turbo upgrade kit. I had problems using their kit minus the ignition ship (regular Ultimate), which were resolved when I swapped back to the upgrade kit ultimate... but that's not to say you can't use the regular Ultimate - MazdaManiac can attest to that.

mysql101

Speaking of which, MazdaManiac is putting out a video about the Ultimate, covering install, tuning, etc. I don't know the ETA on it, but it will be quite helpful for everyone taking the Ultimate path. As time goes on, we're going to be in the majority for the GReddy turbo kit.

I will be buying a copy soon as it's available.

sillybastard

I am totally with you on the fact that it may lean out at certain RPM ranges. I have been taking it VERY easy on the car which has been driving me nuts. It wants to go and i want to open it up sooooo bad it's not funny lol. I have been trying to give the turbo it's break in period, but I will continue to baby it til I get the AFR and EGT gauges installed, just to be safe. Replaing the engine would be more irritating than just taking it asy on it for now!

I just got my Turbo kit last month and it came with the Ultimate, so I am assuming it must have the chip you are referring to.

I am still using the stck exhaust, for now. I want to get al the wrinkles ironed out of the Turbo kit before I upgrade and open up the exhaust. Plus I need to do more research and find the best High Flow CAT and Exhaust system for the Turbo and engine, then get it tuned so that I do not detenate my engine! Hell I may even take MM up on his offer I saw ad fly his **** out to Saint George, UT (Where I live) and put him up and take care of him to tune it for me.

sillybastard

I read about that! I saw his clip of the video and was very impressed. Jeff definately knows his sheit! Like many of you, he is highly inteligent and definately knows more about aftermarket mods and tuning than I do. I have extensive mechanical knowledge, but very limited experience in dealing with aftermarket upgrades and such. I actualy owned an RX7 turbo (stock) and did all my own repairs and such to it. I learned the hard way that Rotary's do like take well to Sythetic oil and it seized on me. Since the motor was basically done; I tore it apart as I wanted to learn how it worked hands on. A very simple and amazing motor! Only 3 internal moving parts! Anyhow........

mysql101

hmmm, if you're babying it and staying off the boost, you should not be getting 8 mpg.
You should be getting close to your stock fuel mileage.

The Ultimate map only starts to inject more fuel when you're getting boost, so as long as you're off boost, it should be running just a little worse than stock.


Not sure what you mean, but synthetic is recommended when you go FI. It'll help the turbo last longer. I plan on switching when I get the greddy upgrade oil pan. I already have RP oil sitting in the garage waiting

sillybastard

By babying, I mean I get on the throttle, but not hard and I shift earlier than I would ormally, 4-6k RPM.

Synthetic is AWESOME for the turbo and was the reason I used it in my 7. Synthetic is BAD for the Rotary as it does not burn well and leaves a gummy residue, which I noticed when I tore the motor apart. It was nasty. I had literally handfulls of this gummy oil build up. Synthetic had just come out when I started using it. When I did research on it; it seemed like the best oil money could buy. It is with the exception of the rotary. So since it is not an option IMO I will just change my oil every 2000 miles and call it a day.

mikeschaefer

I meant which flash is your car's ECU on? i.e. N, M, R, etc.

sillybastard

How Can I tell?

KJ238

U can tell ur flash by using a tool that connects to your odb port... Either Hymee's SCANalyser or harrisons Canscan...

sillybastard

Ok thanks, I will pull it when I can then.

Does anyone have an Unlocked ultimate map I can download? Didn't find one searching. Is it possible to save copy of what is already on there to convert back if I need to?

Thanks in advance!

mysql101

Here's the unlocked map:

http://rotaryinsider.com/files/TK_US_SE3P_RX8.EM2

You can't save the map that is in your EMU unless you have the password. GReddy isn't going to give it to you either.. A moot point since the unlocked map came directly from Greddy and is the same as the locked map.

jenkins-crew

Awesome! Thanks for the ifo and link Mysql !

jenkins-crew

Hmmm..Ultimate still asks for password. Can't you uplaod any map to the ultimate?

jenkins-crew

When you upload the new one does that delete the old? Or is there a different procedure to delete current map?
