Does anyone have the proper PID settings for the drive by wire throttle setup? Any help would be greatly appreciated!!! :mrgreen: :mrgreen:

So another update, We now have 4 World Championships using Vi-Pec powered Hydrospace skis.. Mike Klippenstien just got his 22'nd World title abord our Queen Racing built ski winning the Pro Ski Stock World Title.. More to come!

Queen Racing riders in only the second day of competition have already wrapped up 3 World Championships with their Vi-Pec V44 powered Hydrospace Jetskis.. That is now 18 World Championships from Queen Racing using Vi-Pec ecu's!! Thanks to Vi-Pec for the amazing products and firmware to let us dominate!

any updates?

it still sounds like the fuel pumps are not big enough!! Does each pump have its own dedicated pickup? How do the pumps mate the high pressure together?

haha, after 4 years, you would think I would have noticed that!!! LOL Thanks... That exactly what I was looking for....

I would like to have the rpm limit as a dual mode. So if I have multiple boost maps, I can have rpm limits for each map. When racing Jetskis, I have the skis start in a high boost high timing race mode. After first turn rider flips a switch and lowers boost etc. Problem is is that in High mode, its too easy to hit revlimit and if I raise revs to 10,500 it wont last too long in race chop. So I would like a Di switchable revlimit, to run crazy revs for holeshot, then in map 2 its back to the normal 9100 rev limit.. Simon, any chance of a beta version to test?? :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen:

Just a question, what is your fuel pump? How many liters per hour? How many liters per hour is your injectors at 100%? Do you have enough fuel pump to run injectors like this? I would think you would at least need 2 magnafuel 625 to even come close to fueling this thing..??? Also, wht size is your fuel line for the amout of volume this thing will drink, you should have I would think -10 at the minimum and a -12 fuel rail to hold the volume at the head of the injectors...

I have had the sam issues with staging also.. I fought is so much and I started using aux injection instead and have had much better results as it does not pull fuel away from the primarys.. I run my primarys on q16, and my 2300cc secondarys run on methanol, this setup has been a dream and easy to tune... Just a idea for you to try..

Give me a call, I can give you a rundown of what I have tried and done.. Mark 928-302-0986

I have found better results as using the secondary injectors as a aux injection. The problem I had with staged is that the secondarys come on and the primarys turn off, so the fueling was not reall easy to dial in. Using the aux injection, it is really simple and straight forward, adds fuel under boost without switching off the primarys.. My 2 cyl running on meth and aux injection and 1600 primarys, and 3200 secondarys put down 532hp to ground. With the staged, I could never get it to get the lean transition to go away..

Yes, this is how I do it also.. That should be correct for your application...

When is a RZR plug and play going to come about?

You can also build a small canister, 3 in long and a 2 in pipe with caps welded on the ends. Then put the vac line feeding into this and one coming out and it will mellow out the large pusle. It works well with my large bore 2 cyls and ind throttle bodys..

Perfect, thanks
