Re: I think I need a new CPU

You don't sell them?
Is this something I can source locally?

I think I need a new CPU

The voltage reg gets hot. CPU gets warm. The bottom of the board gets warm/hot. At pins 1, 3, 13, 14 I get the 3 volts, all others are 0 with no CPU. I can get the LED to work for the tach signal, but then it stops after about 5-10 seconds. Now on the board I to get 12v, 3v, but not 5v. With the CPU...

Re: Jumpers for Tach

Thanks, that sounds like a good idea.
Now, how do I put new firmware on the MS board?

Jumpers for Tach

I have a JimStim V1.5 with a V2.0.3 chip. I want to check for a tach signal on my MS3X v3.0 On the JimStim I have the DIPs set at 3, 5, 6, 7 to On position for a Gen 3 Hemi using a 36-2+2 and hall sensor. I have been fighting with this for a while and want to make sure I am not missing anything. The...

Re: No RPM

thanks.
Actually I think that it is a hall sensor. But I tried both ways and still no RPM.
I did post this up at MSextra, we will see what replies I get.

Re: No RPM

I tested the Jimstin board again and all is good. Had the jumper set on 5v pull up for primary tach = No tach movement in TunerStudio. Then I set the jumper for a 12v pull up for primary tach = No tach movement in Tunerstudio. DIP switches set to 36-1+1 (#3 and #5 ON). The MS3 board has an internal ...

Re: No RPM

I don't know if I need 12v pull up or 5v pull up. I was looking in the manual but couldn't find it. The pots R52 and R56 have been set according to the install for a Gen 3 Hemi which is R56-fully CCW and R52-3 turns CW from fully CCW. Actually looking over my notes the crank sensor will be using a 5...

No RPM

MS3X V3.0, Gen 3 Hemi On the JimStim I set the DIP for a 36-1+1. That is DIP 3 and 5 ON. Jumper installed on the top 2 Primary Tach pins for a VR signal. In TunerStudio while looking at the Tach gauge, and turning the either of the two RPM pots on the Jimstim, no RPM is shown on the gauge. I also tr...

DIP setting for 36-2+2

Gen 3 Hemi with 36-2+2 spark mode.
Can't find the dip settings for the tach signal for the Jimstim.

Re: Problems with JimStim, Newbie

OK Jean, I replaced the Q2 transistor. I now get the LED to flash as I turn the RPM Fine potentiometer for the 2nd Trigger mode. It does not flash as nice as the primary tach tough, not sure if that is a problem or not. When testing the primary tach signal the OFF time of the LED is longer and gives...

Re: Problems with JimStim, Newbie

Thanks Jean.
I repositioned the jumpers as you explained and the LED did flash with a lower brightness as you said.
Now to find 2N3904FS-ND transistor.....

Re: Problems with JimStim, Newbie

OK! I replaced the burnt out LEDs and they all light up, including the multi-color IAC1-2. Thanks for the help on that. Desoldering is a real pain. Checking the Tach signal and it is good as well. BUT, when I check the 2nd Trigger, no lights come on. Dip switch #3 to ON, all the rest on OFF. Jumper ...

Re: Problems with JimStim, Newbie

Thanks for the tips.
I will keep them in mind.
Now where can I get these 160-1139ND LEDs in Toronto.
Any contacts??

Re: Problems with JimStim, Newbie

Thanks for your help so far, much appreciated. I do believe that I may have burnt some of the LEDs. I checked for continuity from the appropriate jumper header pins from the DB37 side (short lead) of the LED and all is good. I then checked from the 5v header pin to the chip side (long lead) of the L...
