Hey there u are hahaha!!

As always just the answer to my question. I think I will go with the ones you use that you sent the link to. All I need to do for fittment is machine a spacer to go under the fuel rail where it mounts to account for the extra length correct?
And what do I need to do for the electrical connections?

Ok -- Also order a universal pigtail for each injector. Cutoff the Polaris injector plug and attach the 2 wires to the universal pigtail.

On the spacer -- By the pic I posted you can see what it looks like so you can duplicate. You'll also need a longer machine bolt as the stock one is to short.

Here is a pic showing those injectors in my motor - You can see the orange band and just barely the raised rail support using the Bikeman standoff - Not the best pic but the only one I have at the moment on-line.

When you install the PCV -- Start by pulling 65% (-65) of fuel out so She starts and then trim to attain the desired A/F at idle.

By the way - With those injectors I am able to bring the engine idle down to 500 RPM before she starts to puke and die. I have mine set at 950 RPM and she idles like a kitten .. :)

FUN Times .. :rofl3:

Awesome!! You are the man. I will get them coming while I read up on your posts and the manual for PCV once again so I will hopefully be ready when they arrive.
Your help is priceless thank you again for sharing!!!
 
Sparky's PCV info here should all go into a WIKI. Great stuff. At least it's here and searchable for future use.
I agree. Everyone says that you CANT get any gains from merely adjusting the AFR & Timing, BUT, after working with Sparky and adjusting both in my PCV, there's definitely a noticeable difference. The timing adjustments are what I noticed the most!

Sparky & others,

Thanks for the added info on this thread as well. I'm learning a lot and slowly getting my Aerocharger going. I blew my OEM clutch on the dyno and installed an STM clutch. I wasn't done tuning on the dyno when it happened so now I have an untuned engine & clutch, but its getting there.:rofl3:

I just wanted to point out a few things that I've learned and observed that may help.

BOOST GAUGES - ANALOG vs DIGITAL

"Most" digital gauges use a MAP sensor and read absolute pressure. Only a few (the Autometer digital) will look at voltage at startup and set 0psi (relative) pressure. ALL analog gauges that I found ALWAYS read relative pressure. I found it handy to make the device below to calibrate / check your analog or digital gauge AND to check to see if the PCV is reading the correct pressure (relative). you can just play with the voltage offsets in the PCV setup to calibrate. When initially getting these engines running it is nice to have your dash gauge match what the PCV is reading.

My goal this weekend is to switch to a 100% fuel pressure / absolute table and use kPa. This is what I'm used to in LS / Vortec V8 engines and for me I think will be less confusing. It will take time, but in the end will adjust for altitude changes (which I do) and then all you have to do is have an adjustable boost controller to maintain the correct level as you go up / down in altitude. I'm thinking about switching to the AEM Tru-Boost Gauge / Controller also.

THANKS SPARKY!

I followed Sparky's recommendation and this past weekend took my TPS table and THREW IT OUT THE WINDOW - I PUT ZERO (0) IN ALL CELLS.

I first calibrated my MAP sensor with the PCV adjusting the voltage offset until the PCV read exactly what my manual calibration gauge & my manual dash boost gauge read.

I set the "table axis" to 28 columns, -12 - 0 - 15+ psi. I'm targeting 10-12psi at WOT.

I knew my RZR needed to idle around -55 so I populated all the cells from -12 to 0 with -55. Then followed Sparky's recommendation and subtracted -3 from every column from 0 to 15+ psi. I set "autotune" to +/-25 initially. I later reduced to 15 once my pressure table was closer.

Then I went and drove around. It was amazing how close this "generic" pressure table was. Every 10 minutes or so I would stop and look at "trims". I would ignore the ones around idle as i knew they weren't correct. After about 30 minutes I had the thing running pretty good. From the initial manual setup of the pressure table the biggest autotune trims were around 15

I had a slight hesitation when you "stab" it while cruising and this is where the LCD200 came in handy. I did some data logging and analysed the data on the laptop. It is much easier to see your problem area this way. I then manually manipulated the pressure table and am pretty happy with its performance.

IMO the PCV gets confused or something when running a TPS AND Pressure table. Once I went to one table (pressure) it was much easier to tune and responded to changes in that table. When I was running both I would often make changes to either table and would NOT see changes in AFR. It was getting very frustrating.

Got the injectors coming!! Yeah!!
Ok quick question. Can I plug the PCV into my laptop and get all my tuning inputted without it being installed on the rzr while I wait on injectors or will it not power up on the computer power only?
 
Your laptop will power it without it being in the RZR
 
I'm gonna need to re-read this again. Just got mine, plugged it in and not sure where to begin.

Ok so I have studied long and hard and here is what I have come up with.
Hopefully I am not too far off and my questions aren't dumb haha!!
Ok so first I am a little confused on where to input the information from sparky's first chart
Image

Or is this chart for reference and not to be input into PCV?

Beyond that question I have been configuring and imputing info as I understand it from this thread.
I am tuning by pressure only and am using the 72# injectors
below are a few pics I took from my PCV settings. Please check them out and let me know if I am on the right track.
Image

Top is fuel pressure table and below are settings I want to see if they are correct?

Ok also I understand that pressure and kpa are different. Is there somewhere I need to tell the PCV which I am using? Here is the voltage table I made and I am not sure if It is wrong as it says pressure not kpa?

If my questions don't make sense or someone wants to help out but can't or don't want to explain over a forum feel free to call me.
Thanks for all the help guys

Your pressure table should scale the same way as Sparkys middle column except set the last column 3 psi above your current setting I.e. if your boost is set to 10psi set the last column to 13 psi
 
So instead of -4, -3, -2 and so on it should be 72.395, 79.2897, 86.1845 and so on

I think that made me realize something...
So the map sensor is going to read in kpa and voltage not psi so in order for it to communicate properly with the PCV we must input pressures that have been converted to kpa where we enter pressures so the two units are communicating in the same labguage. If that makes sense hahaha.
 
What do you mean input pressures in kpa? Your pressure table will be scaled in kpa and your PCV will read in kpa with your voltage/pressure input
