Re: Flickering Tach when testing the tach signal

If your voltage drops that much you need to check if anything gets hot and perform the 2nd and 3rd tests here: http://jbperf.com/JimStim/JimStim_v1_5_assembly.html#testing And yes that should be a clean square wave as long as you have set the correct jumper: http://jbperf.com/JimStim/JimStim_v2_0_Wh...

Re: My TIOx setup with 3d printed box.

Thank you for all the details. The links don't work for me (it seems to be for an app?) but I can go to the banggood web site and use your description for each item.

If you have pictures of the whole setup in place and overall pictures of the car, I'd be interested in seeing them.

Re: Question about vr output 1

If the dual VR board is inside the ECU case then you can connect the output directly to JS10.

Re: CAN-EGT AFR serial setup

There are 2 things wrong with this: first, the CAN Id for the CAN-EGT is 1 and second the offset for v0.1.5 (and v0.1.4) is 18. Please post something on the msextra forum about this because I seem to be unable to get them to correct things. I will still send them an email regarding this but a post f...

Re: CAN-EGT AFR serial setup

The only thing I was talking about was the use of CAN broadcasting from the CAN-EGT. And since you're using the DIYAutotune CAN-EGT, you should have posted on the msextra forum in the expansion boards section. Having said that, if you are using 1.5.1 and want to continue with that version then there...

Re: Oil temp input circuit

0.5W is more than enough; even 0.125W (1/8 W) would be more than enough. The only disadvantage to using the 0.5W is that it will be much bigger than the lower rated ones. The needed power rating is computed by V*V/R (where V is the maximum voltage (5V) and R is the resistance) so 5*5/1000 = 0.025W. ...

Re: Oil temp input circuit

The circuit is fine but the value for R2 is quite low. That may be good for precision at higher temperature but that will draw a relatively high current which is not desirable. I would not go lower than 1k. The other components are fine but since this is not something that will change quickly, you c...

Re: Question about vr output 1

The old V2.0 board only has a 12V version. And if you do not have anything connected to the VR+ and VR- inputs then it is normal to see 5V on the output.

Re: Help CAN-EGT Firmware Update

That's the signature you get when it is in bootloader mode and not in normal running mode. TunerStudio does not know what to do with it and the CAN-EGT will only be ready to update the firmware in that mode. If you did not have the bootloader jumper in place when you saw this there is a problem. If ...

Re: Help CAN-EGT Firmware Update

Do you mean the port scanner 1.4 or the port checker? You should not have to use the bootloader header for updating the firmware because the issue is only when TunerStudio reads the datalog over the serial port. The port scanner does not do that so it should just work. But if you cannot get the port...

Re: I/Ox for additional data logging on a Race Car

The functions are correctly assigned in your list. I assume you need a switch for launch control so that would be a digital input. The accelerometer inputs are ADC inputs. And the GPS input uses a serial port. The logger board is no longer available because the GPS and the accelerometer used on the ...

Re: Just ordered a Tiny IOx

The TIOx draws about 50mA of current so you should easily be able to use the 5V supply from the MS3Pro. But you will need to provide some sort of enclosure for the TIOx.

Re: No spark on number 3?

Pin 15 is another ground that you should also connect to the engine ground. And I'm not sure which pullup resistor you mean for the v1.0 board but there is no need for them in your case. And you are correct that you don't want to use Q1-4 and R1-4 when using logic coils. The rest is also correct. Jean

Re: New JimStim v2.0.4 user: Some questions

You're trying to emulate a car battery so that's why it should be 12V which is also a common power supply voltage. But you can use the entire normal range of a car battery or charging system. The ECU is more affected by this than the JimStim.

Yes that looks ok assuming you need a 12V square wave signal for the primary and secondary signals (looking at the 3 header shunts/jumpers). Please note that the 12V and ground you show are for powering the ECU from the JimStim and that you would need to power the JimStim from some sort of power sup...

I understand that I need to wire 12v and 5v to JimStim from ECU to screw terminals. How do I connect power and sensor grounds? I see the 3 pin header next to the DP37. That is just power ground (12v)? Or also sensor ground(5v)? There is no separate sensor ground but only a single ground plane. Abou...
