Megasquirt Support Forum (MSEXTRA)

glad it helped ;)

@Paul_VR6, is this what you are searching for?
I always save the schematics on my HDD, you'll never know when somebody looks for them

the problem was solved.
in the end we replaced the new spark plug wires with some old ones and now the car runs perfect.
it seems that the new beru spark plug wires were faulty (we changed 2 sets and with both the engine behaved badly on hard accelerations).

thanks all for the support!

Hello,

Sorry for the delay, here are the latest data logs: Meanwhile we've changed the MS unit with another one (MS1 v2.2), we changed processors and firmware but the spike is still present, and now I can see a reset.


Best regards.

Tomorrow we will test the car again, and I will capture the log file and attach it.

Hello, Need some help please with random high RPM spikes while in boost (feels like a missfire) Car specs: E30 BMW 2.5 inline 6 non vanos, t3/t4 turbo running at ~1bar, 38mm wastegate, VR6 coilpack , BKR7EIX spark plugs gapped at 0.55mm, Megasquirt 1 V2.2 Hr11d controlling fuel and spark, 440cc Bosc...

Hello, Having troubles connecting my tablet through OTG cable and Serial to USB adapter Aten uc232a (uses a Prolific 2303 chipset) to MSDroid 2.5a0. The Android software for serial to usb adapter will detect it once plugged into the tablet, and I can send and receive data from megasquirt, but MSDroi...

you'll need external igniters to work with the BMW coils, or you could purchase a VR6 coilpack which has an internal igniter, and control it with the logic level drivers.

Here is something that might help you with ITB sizing and other intake related stuff.

from what I know, Autotune will work even if the EGO is turned on and it will compensate.

solved!

issue was because of separate switches for fuel pumps and injectors. now msq is controlling a relay that powers on the injectors, the coilpack and the fuel pumps.


Thanks.

I'll have a look into that, but as far as I know the fuel pump also has a separate switch.

thanks,

Hello, We have a BMW rally car on which we fitted a msq 1 v2.2, the car has all the electric circuitry made from scratch and we verified all the circuits before installing the megaquirt in place.The +12v feed from the battery goes through a general circuit breaker (for safety reasons) and then to th...

I can confirm this behaviour, happened to me when I went from sea level to aprox 2100m altitude, in itb mode with barro correction set to on without a second map sensor, when i was reaching high altitude the map stayed at 85kpa and msq didn't switch to alpha-n even if i put my foot down on the pedal...

rallye antilag like in megasquirt 1 and basic rpm based traction control, usefull for drag racing; Baldur did a mod on 3.2.1 firmware that included als .

10x for all your efforts!

launch control is armed when you press the pedal..but it does not engage if the conditions for launch aren't met.
can you please take a screenshot with the launch control settings?

I'll do a short video this week

use the settings I've posted above, you'll get the roving idle, just play with those settings until it works best for your application

Does anyone have working overrun fuel cut values which gives an acceptable idle with raised throttle stop Position?! over run fuel cut ->on rpm greater than: 1300 kpa lower than: 100 tps lower than : 2% coolant greater than: -40 after delay: 0 lumpy idle, sounds like you have 320 degrees cams :D bu...

never tried 3.2.5, i'm back to 3.1.1 car revs to 7500 rpms without problems.
I'll post some logfiles and msq with the old tune (afr was not logged then because of my faulty lc-1 unit), on the old tune i was driving the coil via bosch 139 ignition module, i had missfires from 5200rpm to 6000rpm.
