Re: Manual for V3.83 of Firmware on TunerStudio

I would be willing to compile an actual usable manual for the Microsquirt Version 3 with MS2 extra Firmware in exchange for a Microsquirt Module

As the documentation currently exists it has too many inaccuracies and conflicting instructions.

Of course I am piqued about the misrepresentation of the ...

Re: GM IAC with Microsquirt IAC adapter

o here is the big rub
Instructions
Prerequisite > "firmware 3.3.x or later"
So evidently the shipping pre installed version 3.83 must be not LATER
So with the firmware downgrade / cross grade to different product basis the options for changing IO PINS are available.
However this version of ...

Manual for V3.83 of Firmware on TunerStudio

Ok so the Help files of TunerStudio MS do not match the screens of TunerStudio MS so is there an actual user manual somewhere that is available?
Is there a software manual for Microsquirt anywhere?

GM IAC with Microsquirt IAC adapter

uS V3.83 firmware
Again the supplied manuals give NO HELP for the newer version of Firmware very disappointing.
According to the manual
Within Tuner STudio open the Startup/Idle -> Idle Control page. IT DOES NOT EXIST!
Under Fuel Setup > Idle Control
Settings are different and incomplete "huh"

Transistors are 2n2222
Caps are .001uF
The input on the left is from any reluctance coil pickup polarity shouldn't mater.
Output will be a 5V pulse on right side.
1n4001 clamps to .7V input if input is non zero output transistor is saturated.
I bread boarded and tried with Cadilac NorthStar ...

Re: GM HEI inconsistent documentation

I see many people have discussed issues with this area of the MEGASQUIRT MS2 that I understand is the basis for the Microsquirt V3 On the MEGA they use a 4N25 Opto that is somewhat better than the MOC205-M.
I think that the 651 would function better.

In motor drivers and other circuits where I have ...

Re: GM HEI inconsistent documentation

The Filter on the Microsquirt V3 was removed by removing R20 C27 C28 D4.
Wiring was accomplished through connector at pin 30 and pin 31 by jumping from D4 anode to pin 1 of MOC205-M U4
Replacement Filter consists of 3mm LED with forward voltage drop of 1.3V in series with 470 OHM resistor accross ...

Re: GM HEI inconsistent documentation

I have simulated tach signal at PW0 TACHIN and showing RPM on TunerSTudio.
Really disappointed at the amount of jiggering with a product to make it work.
Be advised this is not really a direct part for commercial resale but more of hobbiest or hacker level product.
I will reserve my total opinion ...

Re: GM HEI inconsistent documentation

Yep thought of that when I tried using pin33 and pin32 no joy.
Tonight I am looking directly at the opto isolator MOC205M.
I am going to try and trigger with a Gwinstek Function Generator and see if I can sort out a tach signal RPM.
THe GM HEI7 pin module easily lights 3 standard LEDs in parallel or ...
