First dyno plot for stage 1
 
Yup. You heard it right. Received this from Maurice and just made sure it could be posted. This is the first pic. Sorry, no raw data, but I am sure he wll provide it eventually.

Looks perty now, dont it?

zerobanger 01-07-2004 10:22 PM

OHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

is that with no other mods? stock intake/cat/catback?

will airflow mods add more power?

zerobanger 01-07-2004 10:23 PM

just a dumb question, why does it show dyno run 1 and dyno run 2 done at the same time? didn't you have to un-install the unit between runs?

Genom 01-07-2004 10:24 PM

That is a stock car with the stage 1 only. Maurice reported that a test car with Borla had more power, but there is no dyno plot from that yet. I am sure there will be tos more posted in the next couple of days as things get a little calmer for him.

racerdave 01-07-2004 10:29 PM

Just like everyone had said... over 5k the thing is quicker. Now the plot proves it.

That is a significant bump... and one worth getting, IMHO! Ok, I need the car first, but that mod is mighty tempting.

It'll be cool to hear the reviews when people start getting them installed. :D

I think you can safely ignore the time stamp of the files. Obviously two runs can't be done at exactly the same minute/second! ;) At a guess, it's very likely that the lower power run is with the ECU mod disabled, then the higher power run is with the ECU mod enabled (The latest version of the kit, the one being shipped, includes a toggle switch to enable/disable it without having to uninstall). Everything else on Maurice's car is stock.

Gordon

wow...thats some good power..

Speed Racer 01-07-2004 11:20 PM

That's sweet. It looks like the car should really take off after 5k RPMs.

It is also nice to see that the dyno plot is much smoother after 7k RPMs. Nice job Maurice!

compaddict 01-07-2004 11:31 PM

Nice. How about RPM instead of MPH please?

Maurice and stage 1 elfs great work .wowwwwwww.

I am going to be a happy little vegemite if the Australian cars show same levels of performance gains .( BONZA )

Maurice i have set up all the testing crew and equipment needed to test the stage 1 kit for the Australian cars .

All i need is the actual STAGE 1 KIT.

Cheers

Looks like a great gain, but I'm a little dissapointed that the stock car dyno'd so low. With the 238hp advertised crank hp, we should be up in the 190 range (or at least close to it) with a stock car. I was hoping to be around 205rwhp after the stage1 mod so we could finally have the power we originally expected.

Nevertheless, the improvement looks great and I'll definitely be purchasing the kit. PLEASE someone send me the orderform or price list or something. I sent canzoomer an email over a week ago and haven't received a response.

Remember that this mod is giving us back the power we should have had to begin with. The reflash to meet catalytic requirements seems to be what has hobbled the car.

It's a third-gear pull, which gives 1000rpm/10mph, near as dammit. Simply multiply the X-axis units by 100 for RPM. :)

Another guess, but IF those numbers are uncorrected, it's not as bad as it seems. Canzoomer's location is over 3000' above sea level, so it's easily down 10% on power from a sea level car, just from the lower density air. Corrected numbers (Dynojet correction factors account for altitude and temperature, IIRC) would probably add 15 hp to each of the runs.

Gordon

Good point! The power increase is very impressive.

Speed Racer 01-08-2004 07:13 AM

Gordon,
Even though it is a bit disturbing I think that Canzoomer's numbers are correct. If you remember back in August when Mazda announced the revised Hp, a lot of people still felt that 238 was overly optimistic and didn't correspond well with the dyno runs that had been done.

A lot of us took Mazda's word on the Hp and blamed the low numbers on the ECU going into safe mode. Well Maurice has found a way around the safe mode and his numbers are still low. :(

On the upside, his Stage I fuel controller is making sizable gains and it gets us much closer to the car that we thought we had purchased.

Genom 01-08-2004 08:21 AM

I've also noticed that cars seem to dyno very differently at times. My first time on a dyno with the stock car gave me 189. I'll be getting some more runs in when I get my stage 1 to also see if the greddy exhaust is doing anything.

But I need mah stage 1!

racerdave 01-08-2004 09:09 AM

Well, dyno numbers are sketchy at best. Depends on the dyno itself, conditions, dyno operator, etc. The only thing to put stock in is something like Maurice's numbers here... because they're done on the same dyno, the same day by the same operator. Just compare the "before" and "after"... don't try to compare his dyno results to another done somewhere else.

As for the low stock numbers, it's possible altitude played a factor there if uncorrected like Gordon said.

Also, like Speed said, the factory numbers still felt optimistic. Here's my take on that:

Mazda dynos = overestimate
BMW dynos = underestimate

WHealy 01-08-2004 11:05 AM

Ah! And the interest peaks again! Great stuff. Thanks for posting Genom!

compaddict 01-08-2004 03:42 PM

You know after looking at the dyno plot a few more times I am very impressed. Maurice has done a very good job smoothing out the fuel at the transitions as well as making a lot more HP. I sense many, many hours of tuning.

Very nice work!

Vince

zerohour 01-08-2004 03:59 PM

Wow that looks very good I cant wait until stage 2.

RX-8 friend 01-08-2004 05:32 PM

You can see the intake manifold control valves open too. Kind of neat, I thought. I guess they actually do something after all ;) .

700 orders!!!! Back to assembly!

RCCAZ 1 01-08-2004 05:53 PM

700 orders??? Go ELF GO!!!!!!!!!!!!!!!!!

compaddict 01-08-2004 06:23 PM

The hardest part (and most thankless) is tuning everything that isn't WFO.
If Maurice put as much work into that then we have ourselves a real bargain.

Yeah, according to your plot, they kill power!:mad:
When the VFAD opens, there is an immediate loss of power on your plot.
WTF?!?
