Power Commander FC or ECU Flash

[UnicycleMan]

Me again!

Right, so I was all set to get a Power Commander FC installed and a custom map created on the Dyno following the install of a full delkevic decat system, but after a brief conversation with the bloke at my local dyno centre he suggested that I have the option get an ECU flash done as an alternative.

After reading several posts here on the forum, it appears that all who have gone down this route (full decat pipe etc) have used a Power Commander to control the fuelling.

Does anyone know of the differences between the two approaches and any possible downsides of the ECU flash?

Thanks in advance!

Get a custom map done, it'll be far better in my opinion.

Hi, thanks for the reply.

From what I currently understand, the bike will still have it's own custom map set up on the dyno with the ECU flash?

[Mr Nick]

I'd check with him exactly what he meant as doing an ECU Flash can often mean just using a map that was already developed for that model and doesn't involve dyno time to fine tune it.

I'm pretty sure an ECU flash is a generic map ..

[UnicycleMan]

That's what I thought but then can't that map be generated on the dyno and then flashed to the ECU?

Thanks Mr Nick I'll do just that. Reason for asking on here was to get some impartial advice at the same time, just as a sensible precaution.

Thanks both

The maps were developed on a dyno with a bike, just not your bike.

A dyno doesn't produce anything other than figures. The developer runs a bike up on it then uses the data from the dyno to inform changes to the code in the ECU, then repeat the process until they have something that is optimised for that specific setup. If you have anything different on your bike from what was on the test bike, then it won't be as optimal.

Generic maps can be better than stock, but not as good as an individual setup, but they are cheaper as the cost of the setup is shared across the expected sales of that map, whereas you are paying all the cost yourself for a custom one.

I have a custom set up on my K6 with a power commander Best solution all round

I downloaded a map from Dynotune that just so happened to be optimised  for decat exhaust ,aftermarket tail pipe and air filter.
 I may have achieved  slightly better results from a proper custom map
 But I doubt I would have been able to tell the difference.
    PC V maps will work on a PCFC apparently.
