Hello and help question
Greetings!
Over the past two years I've been playing with my MS-3 project and have encountered a snag and would like the benefit of the experience here.
The short version is after changing an ignition coil (IGN-1) and a hall sensor the MS will not achieve sync while cranking. This engine had been running with a different hall sensor so I am confident of the software settings. I can remove the wheel assembly from the engine and spin it by hand and get a perfect sync. I am convinced that the starter is introducing 'noise' that interferes with sync.
There are settings in Tuner Studio to address noise. I would welcome some initial settings to attempt to solve this.
Ignition only using:
36-1 wheel
hall sensor
MS-3 without sequential
Thankssomuch!

Re: Hello and help question
it sounds feasible, can you post logs

Re: Hello and help question
Ummm, with no sync would there even be a log to examine? I did verify that the starter is causing the sync problem. Once I changed the starter to a different model the cranking sync was normal. Unfortunatly I need to use the starter that causes the problem. How can I trap the noise? Capacitor somewhere in the circuit perhaps?grom_e30 wrote:it sounds feasible, can you post logs
Ideas please.
Re: Hello and help question
you can capture composite and tooth logs that record the signals from the crank signals ect under the 'diagnostic & high speed loggers' tab then you can see if its picking up noise usually manifests as extra teeth or if its missing some signals.

Gotcha. I'll fool with that the next time I get a chance.grom_e30 wrote:you can capture composite and tooth logs that record the signals from the crank signals ect under the 'diagnostic & high speed loggers' tab then you can see if its picking up noise usually manifests as extra teeth or if its missing some signals.

Re: Hello and help question
You mentioned it's an IGN-1; what are you doing for an ignition module? The IGN-1 requires a coil driver; the IGN-1A does not.

My blunder! It's a logic controlled coil, whichever number that is.Matt Cramer wrote:You mentioned it's an IGN-1; what are you doing for an ignition module? The IGN-1 requires a coil driver; the IGN-1A does not.
I attempted to get a data log but I never did find the place that it saved to on my computer. I'll give it another go when time allows. Too bad 'real' work gets in the way of 'recreational' work!
Thanks.
