I've rented 4 hours of dyno time later this week to tune my new ecu.

I've watched through the practical standalone course multiple times, I think I know what to do and what to expect.

There's lots of things I'd like to do with that time. But I think I'm going to stick to the basics, just get the VE and ignition timing as accurate as I can.

My old ecu was pulsewidth-based, new ecu is VE-based. So I have to build fuel table from scratch.

I could transfer the ignition map straight over and just do fine tuning on it. But I'd like to follow the process and build it from scratch mainly for the experience.

If I have time left over, what would be the best use of that?

I'd like to get into details like tuning the Charge Temp Estimate table, and injector deadtimes, lambda delay, fine tune the AFR table, optimize the injection timing, and so much more. But I don't want to overload myself, and definitely won't have time for all of that.

What would be the best/most important things to get right this first time out?

And what should I definitely ignore that would be a waste of my time?

I will be going again in a couple months to get into everything I miss the first time, and start working on the advanced stuff like torque management, etc.

Engine is a Ford Duratec 2.3, normally aspirated. ECU is an Emtron KV8.

I've already got all the sensors calibrating and working nicely. DBW throttle is working beautifully. Startup and idle tuning is already decent, I'm still cleaning those up at home before taking the car in.

Just the basics.

Full tank of the fuel and maybe some extra in drums/cans. All fluid levels checked and extra for top-ups if needed. Tyres checked and correctly inflated - they're quite stressed, even at the low power levels you're using. Belts and hoses checked for condition and/or leaks and rectified.

If you're using a lap-top, make sure the batteries are fully charged (you will possibly be able to use mains, but that's inconvenient), you have all the cabling/leads required.

Any documentation you may need to check your work/settings. If you're not that familiar with the software, you may wish to print a hard copy of the relevant pages for quick reference - a couple of pens and paper for notes.

Tools for any changes you may wish to make.
