ATR Request: RPM Axis Increase
 

So cobb has told us in the past that if we wanted/needed something done then we would just need to ask and show support/interest for it. Now that there are some BT cars making real power we would all like to use as much of a power band as possible.

Please post up if your interested in Cobb extending our RPM out in all the tables in ATR. I think 9000 RPM would be a good stopping point.

I will be needing this in the near future.

Gimme dem REVs

Yes please thank you bie

Anthony,

Thanks for making this thread.

I was doing some tuning on a friend's BMW 335xi and they have a scalable RPM and Load axis for the entire map globally. This IMO is all that we would need.

David mentioned that he could implement this in our OEM ECU as well in Pablo's thread here: http://www.mazdaspeedforum.org/forum/foru...ml#post1945892

Attached is a screen shot of the scalable RPM axis in the 335xi ECU.

Ummm yes please!

Yo quiero más RPM.

Yes. Would give me another excuse down the road to get headwork done so I can rev the bitch out

:kabong:
pshhh who needs power beyond 5k?



9000 rpm lol wtf yes!

I am @Downmented; and i support this message.
@Captain KR;

And in case it's not already known, I would absolutely be willing to beta test the functionality once it becomes available.

Thanks a ton for this thread Anthony

Moar rrrrrrrrrrrrrrrrevssssss!!!!!

Can we get some complimentary fire extinguishers too please

In all seriousness...

This platform is flourishing every day and it seems that big power is being made every week.

Because of guys like Pablo, Gerry, Dustin, Mark, Ant, Scott and basically every gearhead this forum has, we are able to adequately fuel this engine without any issues.

6th port and/or Port Injection is the way of our future...and it works.

Big head work, cams, crank keying, etc...are all making its way to becoming a normal thing for this platform.

Without the help from Cobb we will be forever stuck at this point.

Cobb has brought us to a point of which we would have never made it to on our own and for that we are extremely grateful. Now we have created new possibilities and many people are starting to pursue them.

In fact, many already have.

All we need now are the tools to do it right.

I'm all for the tables as well. More and more people are building and looking to make that top end power.

I am opposed to the rpm increase and would like an rpm decrease... :kabong: KIDDING!!!!

Any improvements that can be made I'm all for, of course.

Do want... if nothing more than for the advancement of the MS community as a whole.

Ummm.....

Yes! 3,000 RPM power band sucks the sweat off of old man balls!

I am used to having 10-12k rpm range on the bikes and quads I used to run.

This would be nice if cobb extended rpm table to 9k or 10k


NOTE:
Mazda does make a 2.0 DISI just saying.

If only there was a way to use a 2.0 crank in a 2.5 block, with a DISI Head... daaamn that would be sick.

90mm bore X 81.3mm Stroke with a long rod???

We'd be at a 2.1x litre displacement (high compression of course :) ) AND still be in the good with mean piston speed ~25m/s at 9500rpm

I mean I'm just sayin...

In for this as well, as I will be needing it in the near future with the built motor

I wonder how many people it would take for us to get a group buy together for a destroked crank..... I guess we should just keep dreaming right now! lol

No GB needed if Ford already made one that fits...

The Focus ST has an architecture that we will probably see implemented in future COBB products. Each Axis has its own table that is scalable and is applied to every timing table in this case. I'm in full support of this

http://www.mazdaspeedforum.org/forum/foru...1&d=1380314823

In all honesty, our bore and stroke really isn't that much of an issue revving to the rpm that we would like to go to in the future.

Yes, I'll make this comparison because I came from the Honda world before. There are all motor K series cars with 106mm stroke cranks with 96-98mm bores revving to 11k rpm for them to cross the line in the 1/4.

We need a supporting head and cams that flow well enough into that rpm range so we can utilize a higher top end power band.

In for anything that'll improve our platform.

Supporting head is already available from @SPEEDPERF6RMANC3

Cams will become available once we can actually test them out.

Tough to test cam performance at 8k+ rpm when there's no tuning support for it...

I never said we didn't need the support, WE NEED IT ASAP, there is people that need it already and plenty of people that will be needing it extremely soon. I was simply saying we don't need a de-stroked option to help with this. Also, am very well aware of the head from Pablo as it will hopefully be incorporated into my build once it starts.

Do this NOW please! My motor and BT build should be done in a little over a month and would love to see what I could do on the top end w forged Internals. If this happens...... InBefore10secMazdaspeed!

Put me on the list, I will be building once I graduate collage so I will make full use of this and all of the future improvements.

I bang limiter at 7500 already. Why not more?

FYI if you want to destroke a crank any reputable machine shop can do it for a couple hundred bucks. No need to source a swap or new one.

any comments @David@COBB; or @Evan@COBB;?

FOR FREEEEDOM!

Just think guys, this could be us some day......

As for RPM scaling, it is a bit of an effort to do it "right".

When we did load scaling, we intended it to ONLY affect the necessary tables and none else. Most of the global Load lookups are shared with many other tables, and we want to maintain that style. In addition, adding an axis with individual breakpoints gets the necessary resolution in tuning without sacrificing the range of load values covered.

However, that doesn't mean it is out of the question.

Here is what I need from you guys:

-If you have a built motor capable of running a higher redline, please PM me. I have additional questions that I need answered about the particular setups, as well as testers if I get to that point.

-If you are a user of Tuner PRO (i.e. ATP), please email me for additional information. Most of the protuners here have my email.

-If you are a user that is thinking about using it, sit tight for the time being. I will hold a different survey when the time comes.

Thanks,

-David@COBB

*gone to order upgraded valves and valves springs for spare head.....

Yeah PM sent, let's do this.

Samsies

It seems to me that at this point, we have headwork covered, fueling is covered, manifolds are good, recent builds are showing cams aren't absolutely necessary... RPM is what is holding us back right now.

I'm running out to 7200 right now on stock block to broaden my power band. If (when?) I build my engine, I'd be hoping for 8500-9000.
