A good runnin' PWK is hard to beat
I don't see anyone here 'wanting EFI so bad'. Just some people showing interest in something that 'Might' be a good thing. As I wrote, it would have to offer some definite benefits over my oval bored 38AS carb, for me to spend money on it. All I ever need to do is adjust the air screw and idle, and perhaps change the needle clip position.Rhino89523 wrote:What is it about EFI you guys want so bad, I don't get it. So much work, cash, and extra parts to break to squeeze a few pony's out of a bike so few can use the pony's that are already there. I have carbs on all my stuff we use in the forest and desert and a carb has never left me walking.....I drag home new sensor filled EFI trucks all the time. I understand the advantages but being able to fix stuff with a few basic tools when your 35 miles from your house by yourself on your 500 is a huge advantage too. K.I.S.S. maybe I live by that too much.....does this mean I am officially old?
first of all it comes with a programable cdi, and the EFI for less than vortex wants for the CDI.....What is it about EFI you guys want so bad, I don't get it
Pretty sure there are 2 stroke sleds with EFI alsoRhino89523 wrote:Yeah I hear that, any 2 stroke development is a good thing. I don't know a thing about what it would take but don't some watercraft and outboard motors for boats already run efi to pass some of the emissions crap in california ? Why can't those sensors be adapted to monitor the bike setup and then just adapt one of the bodies they are putting on some of these new fart can bikes? Anyway I'll check out of this thread I'm still running a steel framed bone stock 500 with the stock Pj carb and I'm happy as a clam. I think I'm getting old and set in my ways.
the entire EFI kit with the CDI (all the software is free) is $600+ tax, that includes the dual injector setup, a small one for good atomisation at low revs and the big one and small one for WFOA better CDI set up is the sort of thing that can take 1/2 the cost of this from the big hit of his proposed $1000 / $1300. Something that I had not considered
I assume your talking about your own kit that you're setting up???2strokeforever wrote:the entire EFI kit with the CDI (all the software is free) is $600+ tax, that includes the dual injector setup, a small one for good atomisation at low revs and the big one and small one for WFOA better CDI set up is the sort of thing that can take 1/2 the cost of this from the big hit of his proposed $1000 / $1300.

you cant get a stock carb and cdi for that price
if i werent broke from frying my engine it would be here already
Ok, sounds like a go project. Our system can run this engine. Our CDI's limit is 12000rpm.
You will need 2x injectors to run this engine. both will be installed on the throttle body (42mm). The throttle total length will be 110mm. You will need to make sure the TB fit to your engine (reed valve?).
All components will be bigger than our regular 2T kits, because your engine cc is so big. The price for your engine will be higher than $499, because it's 2x Injectors system , more complicated than 4-stroke one injector system.
You are looking at $599, including the CDI ignition controls.

Yes, you CAN.
You must find out the crankshaft angle between the tab's rising edge to TDC. That's the only info we need.
And yes, you can fully program the CDI ignition map (based on load and RPM).
thanks,
Matt
thats sweet, but the ecu is pretty big, and not epoxied, combined with the price thats a dealbreaker for meforgot to mention, HGT have a 500AF on their 'coming in for set up' list
dosent need 2 injectors but it must be tough to find a big injector to flow enough for WFO, AND still provide excelent atomisation while idling thru the bushINTERSTING you need 2 injecters why? is the duty cycle so poor on the just one supplied that it can not handle a500cc at 100 percent
it is, take a look at the program (free) if you have windows 7 you need to run in compatibility modeodd,the program should be a adjustable to the finest degree of injection timing.
MAP, coolant sensor, and a big spreadsheat for the enrinchment factor for which tempshow does he plan to start from cold?
It requries only 2-3 revolutions to sync. for 2-strokes.
The lowest RPM can be even 120rpm. It depends on the trigger pulse width. Most engines starts more than 200rpms.
One tooth is the default setting for our ECU. We support multiple teeth, 12-1, 36-2, 60-2 etc. all calibratable. But not recommended, because of too much work.
I am located in Detroit, MI. Yes, I can help on rough tuning. I will give my phone #.
The tuning will be mainly on cold start, warm up, then TPS based Load table.
