MS2e MSM won't rev past 4000?
Finally got back to playing with the MS2 after a while and still have some issues. So, it's a Rev built MS2e, 3.3.0i firmware and basemap, stock injectors, MBC (so far) and the usual homemade enchilada mods.
It starts and idles pretty well, fans, alternator and AC also work pretty well. Drives well until about 4000 rpm and that's it. I saw that my timing was fixed at 10 degrees, sent some files to Rev and he had me disconnect my OE boost controller which took care of the Spark Advance but apparently wasn't the real problem. Next, I noticed some strange settings in the Knock sensor that I think fixed that problem but now still won't rev up. Rev did tell me that sometimes it won't load the entire map? I have disabled Knock sensor and Boost control but no change. Doesn't seem like a misfire but just really falls flat at 4K rpm. AFR seems rich but is it rich enough to cause it run this bad? Also, car runs perfectly on stock ECU. Here's my latest tune and datalog, hope I'm just missing something simple; https://www.dropbox.com/s/vibecumayy...44.05.msl?dl=0 https://www.dropbox.com/s/lt8qvg77mq...58.15.msq?dl=0 |
CAnt open tune from work, but what is your rev limit set at? what is your overboost cut set at?

rev limit is not set to progressive or coolant based right?
what boost are you actually hitting? or does it cut even in vacuum? |
Timing is set correctly? Did you adjust pots any? On my recent 99 the pots were so far off that it would not rev above 3500rpms.

How rich is rich at 4k? Just curious.
I had a similar issue occur with my MSM, though different ecu. Are you able to slowly rev the motor past 4k to redline with light load? |
what is normal?
also, are you saying the ms2 isn't plumbed with the vacuum line? you're gonna have to learn how to post coherently or no one will help you. my brain hurts trying to understand that retarded drivel |

I had also quoted the last poster there about pots which I don't have, sorry if that was not "coherent" or seemed "retarded" to you. |

That's because you didn't properly multi-quote the previous question, and it looked like part of your answer. I fixed it.
I'm having a similar problem with an MS2e and MSM, we've solved it by flipping the key off and back on, to power cycle the unit. It works perfectly after that, we haven't figured out why it does it yet. |
composite log. where is it?

VTCS! Unplugged the solenoid, car runs amazingly well. Rev has a setting in firmware but was off in the basemap.
Thanks to whoever wrote this; Mazdaspeed Miata Megasquirt Journal On to the tuning. |
