Q&A Forum
Hi,
So We've been converting my old 200i dynojet to the yourdyno setup. So far I've swapped over the old dynojet stuff and fitted a:
24T trigger wheel
Hall effect sensor for pickup off the trigger wheel
MSD tach signal pickup, coupled to the YD via a 1Kohm resistor into an optocoupler. 12vdc supply to the MSD. Wired as per instructions.
LD wideband controller, connected as per their instructions.
So, nothing really works. The drum RPM does but I'm failing to get any rpm reading from the ignition side, and the lambda is just showing a constant 7v.
Has anyone else used a similar setup who could share what they've done please?
Kinda bit lost here..
Thanks!
Paul
Hi,
With a new YourDyno Standard (the v5) you don't need the MSD tach pickup. You just need an inductive pickup like this for example.
If you rather want to use the MSD you need a strong optocoupler, this is a good board: SparkFun Opto-isolator Breakout - BOB-09118 - SparkFun Electronics
For the Lambda, verify the voltage on the YourDyno Aux pins, and if this is good, check the Aux setup.
Thanks for the reply, can I use the old dynojet inductive leads if they've been de-pinned?
What voltage should I see at the pins? And when you say check the aux setup, in what way please?
Thanks
Paul
Yes, try the Dynojet pickup. If it is an inductive pickup then it is a good chance it will work. Best to clip over the primary (12V) of the coil, not the spark plug wires since it senses current not voltage. Hook it up to the Eng RPM input and configure the Eng RPM in the software.
Aux setup is under Options->Aux channels in the software
Got that side working thanks!
