MS3 on a v3.0 MS3X in LS1 mode
Jim Stim v2.0 set switches 3 & 6, Had to pull up 12v on VR, cam signal in on MS3X #32
I get a ready light in TS and the fuel pump will stay on (fuel pump will shut off if I turn RPM to 0)
But no sync. No RPM in TS, obviously.
Adjusting R11 on the MS3X and cannot get 2.5v on Pad1
Maxes out at 1.67v What am I doing wrong?
Had to remove cam input to get a steady read.
Im thinking Q1 has shat itself and I am seeing a back feed from the output of U7?

Re: Another cam signal fault
Which version of the JimStim firmware do you have? As mentioned on the JimStim web page, the latest firmware version (2.0.4) has an updated version of the LS1 pattern. If you have an earlier version, the pattern may not sync with the cam signal when using the latest MS3 firmware version.

Re: Another cam signal fault

System has the same problem on the car.....
WIll update and retest.
Dang it! Both TTL232 cables I have are 5 volt. Have to conjure one up.

Surplus Gizmo's to the rescue TTL232R 3V3 in stock!
I don't see 2.0.4 firmware, so I assume load the wheels_default.jsw file to update?
Or the wheels_default_ls1.zip ?
I thought further about this issue and although the wheel pattern may be a problem,
That does not explain my inability to get 2.5v at Pad1 of the MS3X

Re: Another cam signal fault
You need to load wheels_default.jsw as defined briefly here: http://www.jbperf.com/JimStim/JimStim_v ... el_upgrade. And make sure to load the latest version of the pattern file because I just updated it with the correct v2.0.4 content.rickb794 wrote:I don't see 2.0.4 firmware, so I assume load the wheels_default.jsw file to update?

Re: Another cam signal fault
Excellent!
Any thoughts as to why the problem setting up the MS3X?
Firmware will not get me 2.5v at Pad1.

Re: Another cam signal fault
Updated wheel pattern on stim
NOTE:
Save the three files .exe and .jsw, Re-name wheel_converter.c to wheel_converter.jsr
wheel_converter.exe on XP did not like com27, had to reassign FTDI to com2
Now I can move on to fixing the MS3X, symptoms unchanged.

Re: Another cam signal fault
I'm embarrassed, turned off stim switches 4 & 5 and I have RPM now.
I still question the R11 setting at full clockwise to only get 1.67v at Pad1
Manual calls for a setting of 2.5v on Pad1 (ZC Testpoint).
