Just need a few details. Whose EFI do you have? Year and type of RZR? Do you have a wideband A/F sensor & gauge?
Be glad to give you my opinion when I know what you have & what you are looking to accomplish.

Bart, how ould you go about checking settings on a TRinity fuel controller without a wideband guage. What do you look for if just trying changes by "feel" or do you really need a wideband to set these up?

 

I have the Looney Tuned EFI Tuner and I DO NOT have a wideband A/F sensor and guage. I have an '08 RZR not a sport. I'm looking to get as much HP and top end as possible without turbo.

 

You NEED a AFR gauge to get a decent tune or your best bet is to have a shop tune it on the dyno for the best possible tune. Your not going to get a good tune just by "feel" Run to rich or to lean and chance grenading your motor....personally I would spend the 150.00 to have someone dyno tune it properly.

 

Will any Dyno work or do I have to go to one specifically set up for RZR's

 

Well they need to be able to tune a vehicle of the RZR's size. So any performance shop that has a dyno and deals with UTV's and quads should work. Otherwise if you pick up an AFR gauge you can get it dialed in pretty close.

 

Thank's Jay I appreciate the help. This beer's for you!

 

:drunk2:

 

how do u hook up an air fuel gauge and does it have to be wideband. they are so effing expensive i WILL NOT pay 100+ dollars for a damn gauge.

 

I take it $5000 for a turbo setup is out :nono:

 

you have to drill a hole in your ex close to the header or if turbod close to the turbo...then weld a bung to the pipe(bung is threded adapter for o2 sensor) a wide band reads more acurate and faster with a better range a reg one just reads plus or minus

 

YES you need a wideband. narrow band ONLY reads the AFR at idle which isnt nearly as important as the full range especially at WOT.

 

Why spend 5000 on a turbo kit to add to an already weak power plant when i can get a webber with a turbo and twice the horse power and 10 times the realablity and a BRAND new motor for 8500? besides thats something i will spend big money on but 100+ for a fucking gauge that will only be used to program a fuel controller once isnt worth my money. besides i have the dyna fs and the remote programmer. just do it with my laptop twice as easy just let the comp do the work for you.

 

thats how you make adjustments but what about if the weatheir changes...you go from sea levle to 10,000 ft how are you going to know your changes are corect...thats what the wide band is about you leave it in and can see real time how things are....
