So everything has went smooth with the S300 system until last night.

I would turn the key forward, Then I would start datalogging and start the car. It would datalog for about 5 seconds before the Smanager would just stop and the light on the s300 would be solid red.

So then I have to shut the car off and restart to make any changes in tune because the s300 wont stay active when the car is running anymore.

I have to do all my uploads when the ignition is turned forward, Not while its running. Sometimes the light on the S300 stays dead green when this happens also...and somtimes the S300 and Smanager work while the car is running.

Spunkster are you going to quote me this?: "If the datalogging stops at a certain rpm the cause is electrical interference, usually originating from the ignition system. Check that the spark plugs are resistor type and that either the distributor cap has a resistor or plug leads are resistor type."

Now that I think of it...My new distributor cap had a crack in it and I swapped it out with the LS distributor cap..Hmmm. The cap from the LS worked fine...But the cap that came off was for a 99-00 B16A2.

The plugs are NGK BKR7E, How do I know if the distributor has a resistor or if the plug leads are resistor type?


Very Obnoxious.

The plugs seem ok. Just check them for any cracks. You should use stock ignition wires. With the distributor cap check the part which makes contact with the rotor - it is a spring loaded resistor. Sometimes it cracks or breaks, which produces interference problems.

The plug wires are magnecor, You thinks those are ok?

I went ahead and purchased a brand new cap today, We'll see if that makes any difference.

I had the plugs out a few nights ago and inspected them, I didnt notice any cracks or anything wrong with them at all.

Lets hope this makes a change in how the s300 is acting.

Only use stock plug wires.

Well,
I went ahead and bought a new distributor cap and swapped my wires to stock wires.

So I now know that those things had absolutly nothing to do with why Smanager would lock up.

How bout this, everytime I turn my blower motor (heater) on or off Smanager locks up and somtimes the s300 locks up all together, when that happens I have to turn the car off then back on to reset the ECU.

Ever heard of that happening before Hondata?

Time to start checking the rest of the wiring. Pull all the ground point bolts off, both inside the car and in the engine bay, clean down to bare metal, and put back together. The locations should be listed in the electrical section of the manual.
