10AE Miata Dyno

~102K miles
Done in 5th gear Mods: K&N drop-in filter Racing Beat Header FM high-flow cat & midpipe Cobalt Muffler Regular Oct (85oct in Colorado) I just installed a BP5A Mazdaspeed cam and will redyno soon (at the same place) to hopefully get a decent delta.

I'm curious what the differences will be between the cams. Let us know. I have a set of them on the shelf, too.

So it'll be: - Run with delta between my above baseline and BP5A cam. - Run with BP5A ecu - Hit the track I'm doing things I wanted to see, the small incremental changes so I (others) can know what these 'smaller' mods yield. Depending on my results w/the ECU I may/may not go with some sort of standalone or really good piggyback. |

Kinda disappointing results. BP5A cam with stock ecu then BP5A ecu. The first and second run i got 112hp the following runs were with the BP5 ECU (JDM ECU) where i got 116hp but lower tq and powerband from my baseline run.
Baseline run and mods at top of thread. I also found it odd that the jdm ecu would fuelcut at 7k on the dyno but afterward was easily going to 7500. Also i was running the jdm ecu prior to dynoing and switched to the usdm unit before making the 5mile drive to the shop. After 2 runs i switched to the jdm ecu. Not sure if hot swapping the ecu's contributed to the loss since it didnt have time to 'learn' prior to being ran. In short, I didn't gain HP w/the BP5A cam and also have a lower overall powerband from my baseline. The JDM ECU got me back even with my baseline peak HP but also was unable to match and/or exceed my previous baseline powerband. Discuss. Really disappointed. |
I don't know what I was expecting, but that wasn't it. I guess I expected something more dramatic.

Well that's a bummer. Long shot, but I read one incident where someone ordered an MSM cam and received a plain old 99-00 cam. Easy to overlook. Can you triple check the cam?

I looked at it before getting it installed. Both the box and cam had the BP5 designation. Maybe it was just the case of the conditions although i tried to mitigate best i could, cuz i swear the car pulls stronger on the road. Going to track at a roadcourse when the weather clears up.
