with engine off, can datalog
engine running wont datalog at all.
we were using a non resistor plug, but today switched to a iridium resistor plug. I was hoping this would fix the dataloging problem. It didnt.
Would the location of our ignition box be affecting dataloging??
The M&W pro10 is mounted about 1 ft away from the ECU.
Will this cause the s300 to not datalog??

Use of aftermarket ignitions can cause tremendous amounts of intereference and will cause you to have dataloggin issues. The stock ignition system should be capable of the power you are making.

it made 560whp at low boost. i don't think stock ignition will do much for us at full boost.
meh. ill figure it out.

Using non-resistor plugs can permanently damage the ECU.
If using an MSD then use the stock ignition wires, the stock distributor cap with the built in resistor on top of the rotor, and resistor plugs.

Ill try to throw this ecu into a buddys car and see if its datalogs to verify if the ecu is damaged.
as far as the ignition right now.. M&W pro 10 box. NGK blue plug wires & resistor plugs. MSD cap with external crane PS92 coil. stock oem GSR rotor.

Moved the M&W out into the engine bay, made sure to use shielded wire everywhere possible...
Can now datalog perfectly fine :D
So for us guys with aftermarket ignition boxes... just be sure to mount them far away from the ecu
Hope this helps/helped some people.
