questions about dataloger and fuel pressure
With the VTech dataloger can measure fuel pressure? and Vtech electronics vary the fuel pressure?

Yes you can but measure and log it. No, it can not control fuel pressure.

Sea Doo has an fuel pressure sensor? or it calculate?

every map is different
some are mapped for a rrfpr some not

that maps are those who need fuel pressure regulator?
those above 8,500 rpm?

It really does not mater what Vtech tune you start with provided you have several things covered.
You have a Vtech logger or a CMD logger. Both have a version of Autotune but they work very differently. I happen to have both. CMD is a little more "Automatic". Vtech is a little cleaner in the long run. At this point, my ski has all tuning being done in the Vtech and the CMD is only there as a high speed data logger.
You have very consistent fuel pressure that is always at least 45 PSI higher than the pressure in the intake.
You never get over 75 PSI in the fuel rail at any time as the stock fuel pump is likely to fail.
You are willing to customize the tune for your ski or have someone else help you tune the ski for you.
PS, these basic rules apply to every ski on the market stock or modified. The max pressure limits may change from brand to brand. Motec has the tools to do this in one package, the names just change.
