Trying to get pre-crank injector pulses

[kilohertz]

Thanks Taylor,

I just got back in from the shop after testing my latest tune, and I have pretty much dialed in for now. Shop was 2C and it fired right up and idled properly at 1000 RPM, slowly dropped to 900 after 7 seconds then slowly dropped over the next minute as it warmed up, to the target 700 RPM at 75C and above. No surging or bouncing off the idle saver, it just ran nicely. I have decided the pre start pulse isn't required.

Shop is up to 12C and I am heading back out to weld up a temporary exhaust so I can properly install the O2 sensor for some CL tuning. I have 2 exhaust stubs with bungs from a Vortec engine so I can put NBO2 on one side and WBO2 on the other. I have an Innovate LC-2 and it will be nice to see the WB data.

Here is this mornings data log file.

Cheers
