The Minority 8 [ECU and RE-Intake]
I just got back from my 3rd dyno day. On 3/31/04 I did some comparisons between Stock and the RE-Intake. My 8 happens to be a minority 8 in the aspect that the RE-Intake made me lose about 15.8 hp peak, which also carried on through the mid-range. Another oddity of my 8 is that I was peaked at 185.2, almost all other 8’s dyno’d at this shop I believe were in the low 170’s. I began to think that maybe the reason for me being a minority was that my car had a different ECU setting. My car arrived in port on 7/13/03, maybe that’s why.
So I received the latest reflash from Mazda, I couldn’t find any sticker to tell me the letter. So either L or M. Today for comparisons we did a stock run, now it seems I’m no longer a minority in HP.
Latest Flash VS Old Flash [4th gear pulls]
Max Power: 167.2 @ 7.2k – 185.2 @ 8.2k
Torque: 136.1 @ 5.2k – 137.3 @ 6k
As you can see, a big drop. I’m also back in line with the other 8’s. You can also tell the difference starts right after 5k.
Now to see if I was correct, I ran the RE-Intake. I gained 4 hp and lost a little torque in the mid-range.
Stock Vs RE [3rd gear]
Max Power: 177.4 @ 8.8k – 182.3 @ 8.6k
Torque: 133.9 @ 6k – 130.5 @ 6k
So the RE-Intake does work. But I want my old map back!

Didn't I read somewhere that it seemed to people that the newer L and M maps seemed to be better throughout the power band, possibly at the expense of peak power? Without looking at numbers, can you tell the difference when you drive it?

Yeah, I wouldn't rely on just a few dynos and with this cars temperment it's tricky.Temp can play a big difference after heat soak. You probably have the same power as before, maybe even a little more after the flash. Try to get the same conditions (Temperature,fuel, tire psi, ect) as before when you ran the 185.2 H.P. stock.
