Re: The Val
Couple of 5V6 zener diodes accross the reluctor wires and moved the reluctor sensor back towards the crank trigger. Not seen a single RPM spike after lots of running today
Now to just get the tune sorted... WB is useless below 2K RPM from cam overlap and getting 70kPa MAP at idle in neutral which goes to 80ish KPA in gear

Re: The Val
Looks like a dizzy mounted reluctor + MSD = bad. Now with the crank trigger and some clamping diodes misfire is no more!
A video and a log from last nights Fast Friday event. The vid is of the first pass, timing system wasnt working so not sure of the time. Was a bit rich so leaned it out slightly, second and third passes were both around 10.10 @ 131 MPH. Not had a full WOT pass after making some tune changes after qualifying so hoping there will be more in it!

Re: The Val
she sounds mint good to hear the results of the diodes were as desired too!
i have been very "reluctant" to do anything more with my abs trigger but i will now

Re: The Val
I've fiddled a bit with different R's and C's across a distributor reluctor coil and you start loading them up and you get phase shift and you end up with easily 5-10 degrees retard.charlay86 wrote:Maybe just needs some low pass filtering to stop the voltage getting too high when the revs go up.
if it is already close to working you might just be able to move the sensor back in to where it is happy to start and put a series RC filter across the reluctor

Re: The Val
is that something that changes with rpm's though or stays fixed through the rev range ?

Re: The Val
As the frequency (RPM) changes so does the phase change.
Re: The Val
who said anything about RC filtering
I thought about zeners too, but wasn't sure how the input conditioning on the module would feel about the squared off signal, since it was potentially saturating internally, which would have a similar effect on the signal.
