Actually, I knew what you were going to say about this... I was giving ypu license to explain it before someone else asked about it. :DThis is what I was after. That's a 45 WHP gain, and with a Stage 1!!! :D

Lufa

Well... that is what I was waiting for .

I wanted to wait a couple months for the early adopters to work out any potential bugs, plus to see if any one blew thier car up . Also wanted the technology to mature a little bit more. I can not wait to see the latest Dyno's of the new and improved stage one.

Fuel economy + more horsepower + street legal +self install/uninstall = $600 to you very soon.

Great job!

Hi Maurice,

Very impressive job done, so far !
I'm very excited with the great results and the huge job that you and your team have accomplished.

But I have some questions : what about the new Mazda flashes for european RX8 ? Are they the same?
And if there aren't, did you have the opportunity to test your "new" stage 1 against an european mapping (stock or reflashed)?

Cheers,
Cosmos

Beautiful. I get more excited every day. Looking forward to my Stage 1.

AWESOME RESULTS CZ. WILL BE ORDERING SOON WHATS THE WAIT FROM THE TIME YOU RECEIVE ORDER. ANY UPDATES ON HOW THE STAGE 2 IS EFFECTED BY THE NEW MAPS. 45 WHP IS VERY IMPRESSIVE FROM A STAGE 1 AND IF IM NOT MISTAKING THATS CLOSE TO YOUR PREVIOUS PREDICTIONS OUT OF THE STAGE 2 KIT. COURIOUS ON NEW PREDICTIONS ON STAGE 2 AND RECOMMENDATIONS AS THE BEST MID PIPE AVAILABLE IN YOUR OPINION.

THANXS FOR THE GREAT WORK. MY HAT'S OF TO YOU FOR MAKING A GOOD CAR AWESOME. WATCH OUT PORSHE THE ROTARY ABOUT TO BE A MAJOR CONTENDER.

since you have the most experience with the new "L" map, in your opinion would it be wise for everyone (even if not using your chip) to get a reflash? Do you have any comparisons or info on how the latest Mazda map compares with the original map the first cars over here have with respect to hp or mpg?


btw - awesome results!

OK serious Question here Maurice, I have an american car in Germany and these bozos are tellin me I cant get my ECU flashed SHIZER!! anyway, is there anyway to incorperate the new flashes in your piggyback? Ill be ordering the cable and software from ya to upgrade to stage 2 so hopefully that will help me out?

canzoomer

Sorry, can't help with that.
The flash is done by the dealershiop, and they use the OBD port in the car under the dash to talk to the ECU.

Don;t worry, the maps we ship now will work fine with both older and newer flashes.

hootersam

CZ,
Are you still recommending not to use the K&N typhoon with Stage 1?

Omicron

Or ANY aftermarket intake, for that matter?

sixspeed

Sorry to be a nuisance.....

What is the effect of the new maps for stage-1 for the UK buyers of the kit? Are you going to be shipping the revised kits to us, or will we still get the "original" stage-1?

Twin 8s!

CZ,

Great data, now I entered next phase...

The damn I can't wait till it gets here phase. I am going to continue to watch this thread for more data on how to request a reflash and the results of more testing... this is great stuff.

Thanks Maurice.


Dave

PS... will be interesting to have a stock and "enhanced" RX8 to compare. I can't wait!!!

Wow, lots of variation from one site to the next. I get even more variation than you are because of my disproportionately higher trap speed.

Plugging in my best run to date (14.407 at 100.97 MPH) I get:
212 HP from ET and 257 HP from speed
211.56 HP at the wheels and 274.9 at the FW
and, from the last site (the most optimistic)
257/303 HP from TS and 212/250 HP from ET (wheel/flywheel)

That means an average of 230 HP at the wheels and 276 at the flywheel.

I wonder why the G-Tech shows such a significantly lower HP rating than the calculated methods?
Your average HP (from the G-Tech looks like about 150; you don't have the HP page open, so it is hard to tell exactly). Mine is similarly lower at 178 or so.
What is the G-Tech doing differently than the formulas on those WEB sites?
BTW - I don't have a correction factor. The temps and pressure at my altitude yielded a dyno multiplier of 100%. I don't know how much that factor really plays into power output.

I'm confused about your fuel economy results:

1. I was under the impression that your maps only adjust "wide-open throttle" conditions which are 85% or greater throttle positions. I wouldn't think that the throttle would be open that far on cruise control going 84-90 mph so why is there a difference between old Stage1 map and NEW Stage1 map?

2. If your Stage1 kit is now making adjustments for partial throttle conditions (like I would expect when using cruise control), won't the car's ECU "learn" about your adjustments and "correct" away your new partial throttle maps?

I'm having a real problem finding a dealership that knows anything about this reflash, or any reflash for that matter. I've used the term "L" reflash and "L" maps and they don't know what I'm talking about. I've called 4 dealerships in my area and I even faxed them the service bulletins that CZ posted in the other thread about this. Those bulletons make reference to the "L" calibration. Any one have any advice as to what I should be asking them for?

Rx8Freehk

ya man, on those service bulletins, there is a part #, tell them to READ

1. Your impression was wrong - Canzoomer's mod has always been tuning the full 3D map, not just WOT. He has spent a huge amount of time tuning part-throttle operations, and has written a fair bit about that effort in various posts.

2. Nope, the feedback looks to the Canzoomer maps, not just at the original pre-correction map.

Gordon

Thanks for your reply. Maybe you could help me out interpreting some of CZ's e-mails to me then.

At one point I asked him, "What are the chances that the computer in our cars will be able to use to O2 sensors to figure out your MAF trick and readjust its maps to negate the effects of the mod?"

He said, "Answer is they can't. The O2 has a range of "OK" that is quite narrow. It is not a wideband sensor. Basically it measures AFR between 13.7 and 16.4. As a result the ECU only uses it for partial throttle stoich conditions.
The ECU falls over to a fixed map at beyond 85% throttle.
In WOT conditions the map is derived from our box, plus adjustments from the barometric pressure sensor."

Again, in another e-mail I asked, "Wouldn’t it be best to leave partial throttle maps alone and only modify WOT (>85%)?"
He replied, "We do!"

So it sounds to me like he's saying that he's sticking to only modifying WOT conditions so that his adjustments are always based off the fixed maps.

I have not seen Maurice's maps, so I can't comment on what happens at less than WOT. He has seen my maps though, but he didn't seem surprised that I was tuning mid-throttle so I assumed he was doing the same.

On my E-Manage system, I tune at 20%, 50% and 70% throttle opening as well as WOT and the settings "stick". There is some fuel trimming that is supposed to be part of the ODB-II standard, but I haven't observed it actually taking place. I suspect that some of what it tries to do is dependent on what readings the PCM gets from the initial calibration of the MAF after a PCM reset, which is changed by the E-Manage and its interception of the MAF signal.

What is important to note, however, is that the OEM tuning is not nearly as outrageously rich at part throttle across the whole RPM band as it is a WOT. Therefore, it takes considerably less correction in those ranges to make them feel right (which is all that matters at part-throttle because if it isn't fast enough, you just give it more throttle).
Furthermore, you can run extremely lean at part throttle. In fact, there are parts of the OEM map that hold at 15.5:1 or leaner!
I have made some of the other parts of the map hold at stoich (14.7:1) but I haven't tuned for 15:1 or less. Perhaps that is where the fuel economy of the "L" map comes in.

Additionally, what he said there is incorrect.
The RX-8 has two O2 sensors, one of which (the unit before the CAT) is a wide-band, current-based sensor that is used (seemingly) at all throttle positions and A/F ratios.
Whether the OEM maps actually call for an 11:1 ratio or not is a bit of a question still. The PCM may still be allowing the MAF to rule over the WBO2S, which seems to be the case since I can change the targets with just the MAF table.

So now the Stage 1 is apparently a 40-45rwhp increase. Does this mean that Stage 2 will be higher?

I know stage 2 has more aggressive maps as well as ignition advance with a high flow cat. However, the new stage 1 seems to include ignition advance also.

Does this mean that the hp jump from stage 1 to 2 will be smaller?

Is there any way to tell what version you have? Who knows what I got, A, B, C, D.......

I'm guessing no, huh.

MazdaManiac

Well, you can tell with the WDS at the dealer.
Otherwise, no.

brothervoodoo

At least you can determine if you don't have it (or better yet, test to make sure you do, after you get it flashed by doing the procedure listed at the bottom of this TSB).

Whenever I try to depress the brake pedal 20 times I cant even do it 5. It's like the pressure from the brakes gets too great and I cant even press down on the brake 1 millimeter let alone what it would require to test this out.. what am I doing wrong?

David...

Quick Q.

Whats the fuel economy and power/map like with just 'L' map on its own?
