Nope, not really. If they have been properly built, and properly tested... but why would it matter anyway? A new ecu has a proper guarantee and can be sent back/swapped for free
To get a DECENT! ECU that will run sequential injection is not as cheap as you make out.
Lets compare a L6 ecu that is perfect for any of our engines to provide the same if not better results than an aftermarket version. This costs £100-150
Now what model OMEX will run sequential and at what cost? £650 at least. Thats without any wiring etc. Also it will use all the same sensors if it was on weber or omex.
So how about others like pectel we all know that is top of the range and will again cost at least £500+ for the low models. Then we have the likes of life racing etc. Which the ecu is 1k.
So the build quality of the ecu and many other costs come into it too.
I could carry on but some people wont learn by others mistakes and require making them on their own.
Sequential injection seems to be a really big selling point for some ecu's, however the number of people who could give a technical answer regarding its merits don't seem be that numerous... Perhaps you could explain it mate? Im interested in how sequential injection behaves at high RPM, with tiny injection events and a high injector PW... When you map weber do you alter the injector timing? or trim individual cylinders? Is the YB just similar enough that the injector timing doesn't matter on a cvh? Can you adjust injector dead time to suit different types of injector...
Although this might look like a dig, it really isn't. I am genuinely interested to know why you recommend one system over another just because it does sequential injection?
