thanks Al for checking into this.

I'm still having the same problem with the NB settings but here's the thing- I do not have an o2 Sensor hooked up. I have an innovate WB but I only use it to setup my VE table then pull it so that I can use it on other cars so in normal operation I do not have an ...

The revision notes for changes on v3.43 specify:
Old Equation:
Pw = Topen + MAP x VE x ReqFuel /
New Eq (model-based):
Pw(sec) = Topen + ((MAF(g/s) x (120 / Rpm) / No_cyl) / AFRTGT) / InjFlowRate(g/s)

In reviewng my Datalog, the PW is most definitely the problem in my case. For example, idling ...

Hello,

I loaded v3.43 software last night. I manually entered all values from a fresh .msq to match my old setup with v3.23 and now the PW's seem to be way longer than they used to be (was ~4ms at idle, now ~32ms). I've looked thru all settings and checked out a datalog and all gamma enrichments ...

I saw this thread, started writing a response, then checked my thread on my success and saw that you responded! http://www.microsquirt.com/viewtopic.php?f=89&t=23224

I THINK I'm using L or R version COPs. I have been running these coils for 4,000+ miles now and no problems (with the coils anyhow ...

Thanks for the replies. I changed my Tolerances accordingly.

I took a datalog today over lunch so the engine was cold (not as cold as yesterday morning). In comparing the two the problem seems transparent. Trigger +/- is fine but note that on the old datalog injector pulsewidth stayed 3.4msec but ...

Sorry I've been away visiting family for the holiday.

I will check into this as soon as I have a chance. I'll do a point to point check from the Microsquirt AMPseal connector to the 3-pin VR sensor connectors.

I need your guys' help, I really don't want to take a half day but my car is not starting!
I'm running COP on a Microsquirt, have put on about 3500 miles on this setup.

My car starts fine at any temp (tested up to 32 F) when the starter cranks at ~ 180 RPM.
When it's really cold and I don't have ...

Thanks for taking time to record the waveform.

Strange thing is the car runs much more stable with Falling Edge and I am using a Microsquirt. I assume Microsquirt VR inversion would be same as Sequencer.

I have probably about 3 hours of driving time with the Falling Edge setting now and I have not ...

vrin1(+) is DME pin 27 and vrin2(+) is DME 26.

I connected both vrin1(-) and vrin2(-) (DME pins 8,25) to the Microsquirt pin 33.

DME pin 27.
