More fuel to the fire. Red plot is same as the one I posted a page or two back. This is just to illustrate the difference in area under the curve after a reflash. Where the OEM tune starts to nose over at 5800 and wheezes to it's 6600rpm soft cut, the reflash is still climbing to a peak around 6700 with over rev capability to 7300. Night and day behavior even though the peak is only 14whp difference. At the OEM redline, the reflash is making another 21whp and still pulling hard. Moral is, regardless of which exhaust you do or do not install and which reflash you choose, do it.
This is my tune on EcuTek, still learning the ECU. Maybe 50 total pulls with a variety of exhaust since we got the car 13 months ago. Most of the pros offering reflashes for sale have thousands of pulls with their software and/or SAG's.

Well, the rest of the world, including Japan, got 1.5L for tax reasons. It seems like they spent more time developing that combination and then realized from press/owner feedback that 1.5L was not going to cut it in the USA. The 2.0L seems like a quickie shoehorn job in comparison. Witness the tranny issues and the top end strangulation (which the 1.5L apparently has a lot less of). Just my take, mind you . . . .

Actually the 2.0L decision coming late in the ND development cycle is basically true. The decision was taken after feedback from US that the 1.5L would hurt it in the US market.
The 1.5L is zingy with sport car-y top weighted powerband. The 2.0 SAG is the motor from the 3 almost verbatim, only a slightly different exhaust cam, header and tune.

As an engineer, when scope changes come down the pipe late in the cycle the process is:
1) make it physically fit
2) wire it up
3) turn it on
4) test it per the spec
5) management promises to implement the fixes/improvements for non spec failure type issues at a later date
6) ******* ship it

My ND is the 1.5 Liter version and I am amazed with the Engine until now. It“s stronger that any stock NB1 (Even with 3.9 and 6 speed) and any stock NB2 that I have tested. I use a local Dyno Dynamics and every NB1 with bp4w never reaches 140 Hp, they deliver about low 130 , the NB2 with Bp-ZE never reached the claimed 146, they do about 138/140. And I have dyno“ed over there more than 20 cars.
My little 1.5 made stock 139 Ps and 165 nm stock, and now with Ovtune i am at 153 PS and 175 nm. This was on the 3rd tune, now were are on the 5th revision but due to health issues I have not driven the car for a couple of weeks. Hope to be on dyno maybe next week or the other. Just for curiosity, it weights 980kg with ¼ of tank of fuel on it J
Ps: Power at the fly.

I was just musing. No call for the "M" word. I wasn't in on the product planning, and neither were you. But I work full time in engineering and dealing with regulatory agencies, and I know how these things go. I know that Mazda left no fat on the car when it engineered the 1.5L version. It also seems that, other than the motor, there aren't significant differences between the 1.5L and 2.0L cars. Compare that to how different a 1993 NA 1.6L is from a 1994 NA 1.8L . . . everything on the car is upgraded for the bigger motor and evolving safety standards.

The BP-ZE numbers you are saying are in the same format as the 1.5 ND numbers? The 1.5 makes 25 nm more of torque??
Also, it looks like the stock redline was about 7400 and you are going up to 7700 now?
I think a C15-60 Rotrex on one of these engines, revving to 8k, would be insanely fun!

I hope your health improves soon.

Yes, they are. Stock the 1.5 makes about more 15nm than a BP-ZE and with Ecu about 25 nm more and 14/15 Hp more untill now.
Agree, a Rotrex on this would rock
