The Fuel Injection Thread

[ADVJake]

ok so who has done it?
I'm seriously considering it for the benefits of smoother driveability, less tuning hassles, fuel economy, no flooding, ease of starting.

Carbs are a great thing for simplicity, but are a compromise everywhere, except maybe the FCR41, but then you have something that drinks the gas and still floods

All the info i can find on TT are for the XR-L. Not sure where to start.

Anyone?

That's to futuristic for me, but here's a bump.

[rcnutt]

the new trx700 quad has FI and electic start that could be added to a pig, seeing that the 700 engine is a 650r punched(and maybe stroked alittle). pricey parts though, but what a nice clean install.

[Mythic]

Yeah, I've seen alot of talk about the TRX option on other boards, but everyone seems to balk once they figure the psrts cost. Maybe once the quads start showing up for salvage & parted out this will be an option, but buying all the parts from Honda doesn't make $ sense right now

i will be working on this soon.the ecm will be a unit called a microsquirt-it is programmed with a laptop.it is an off shoot of the megasquirt system i use on my car.i will also be using a wide band 02 system for an input to the ecm made by innovate motorsports.this will allow the ecm to be accurate at all altitudes and air temps.i will be able to have a digital afm gauge to see while riding.i will be scrounging for an rc51 throttle body assembly on ebay-somewhere i read where you can split them.or have 1 made by a comapny called extrudeabody.the innovate wide band will come soon though because i want to try it to check my carb.just bought my pig used .it has an edelbrock on it but it also has stock carb too.probabaly a run off between the eldo and oem carb while being monitored by the wide band 02 is in the works.reason for efi is the ability to correct for altitude change automatically.the eldo seems a little rich right now

I don't see any advantage to the edelbrock for the $. Perhaps a little better MPG. But I see a lot of advantages in EFI.

Thx.

Restarting an old thread...anyone have an opinion on this:

Small Engine FI

Looks very interesting to me and the TB size seems to be right in the ballpark.

Currently running stock and Edelbrock on three different XRRs and all run well but the idea of custom, laptop tuning and two different modes is appealling to me. Price is about right too, imo. Necessary mods don't appear to be too difficult.

Comments?
