2015 F/I Drive questions

[flharleycop]

I currently have a EZGO 36v that goes 19-20 mph stock. I need more range and speed so I am looking at gas models. I was going for the EZGO gas but today at the dealer (he sells both) they said that the Yamaha with F/I 11 HP would be faster than the EZ 13 HP in the long run. They said that I would be able to get 25-27 with the cable strap and adjusted once it was broken in. The EZ go Kawazaki was not as fast or reliable as the Yammy 11 HP. what are your thoughts, I don’t want to get a new cart and not get the 23-25 MPH in stock mode. I they only go 20 stock doesnt seem smart to get rid of my current cart.

I was in a new TXT at the golf course today and it is FLAT. It doesn't have much torque

From my understanding even if the governor is conplelety bypassed on the yamaha FI models the ecu will still limit the max rpms thus still limiting the top speed. I would say with the governor zip tied to the max with 23" tires you might be able to get 22-23 mph. I have owned 3 yamaha g29 carberuated carts and I know what they are capable of doing but to save the engine at high rpms you have to do some modifications that will void the 4 year warranty. These mods come from a company called plowmans carts which is a sponser here. When you raise the governor for max speed or bypass the engine needs more fuel to accommodate. What ends up happening over long distance runs the engine runs lean which in turn makes lots of heat. The plowmans kits for carberuated carts include larger fuel jets to increase fuel at higher rpms, you mod the airbox to allow the engine to breath in more air, you use a high flow afe performance air filter that is lifetime use for more flow, he includes a extreme Kevlar belt that is wider and shorter to give you better grip and lower gearing, and finally a different clutch spring for the driven clutch to put the power band in the higher rpms where you really need the power. After these mods the cart is a blast to drive. Very peppy and strong. Will pull a tree and climb a canyon. With no lift of large diameter tires 30 mph is possible, with 22-23" tires 33mph is possible.

I can't say a whole lot about the efi models though. It will be the best 200$ you ever spent guaranteed. Call plowmans and ask to speak to don. He will talk you through the entire install and give you his recommendations on what you need from how you tell him you will be using your cart. Tell him BJ from Alabama told you. 810-736-1100

On a side note the 2015 models now have a good transaxle and not the team industries anymore which is a plus

Thanks for the info, I will call and see what he says about EFI>

so what RPM does the fuel injection limit cut in ?

my carb 2011 g-29 will do 31mph by GPS

[dbmachine]

I have no idea what rpm it cuts off at. Cgtech would most likely know the exact number. Don't remember 100% who posted that the ecu cut off at a certain rpm but know for sure I read it sometime back here on the forums.

flharleycop, I have the new "Drive" F/I and like db is stating, the fuel injection appears to have an ecu cut off. I am not 100% sure on that, but when I tested out the zip tie on mine, I went from the stock 14-16mph to 21-22mph. I have 23" tires and not other mods. I am happy with the stock speed for now, maybe after the warranty runs out, I will start to play around. By then, there will probably be a lot more add-ons for the F/I models. Just my opinion for now.

I am good with 22mph, do you see any issues driving at that speed for about 4 miles straight?

Never measured the Rpms, but i can attest to a rpm limit in the FI computer. I'll have to get around to testing that.
