i have 3 different audi coils and a bmw coil, just trying to compare if one give out a better spark than the other.

is there anyway to measure the ouput from a COP (coil over plug)? i have a scope, just dont know what points to measure.

also what will be the easiest way to fire up a coil on the bench? i have a function generator, ps, scope.

I think we need a little more information here. How much fuel flow and pressure do you need? Are you using a throttle body injection or direct injection? What's your price range?

need atleast 45psi, direct port, dont want to spend over 100. it only going on a 600cc motor, i was looking for one ...

im looking hopefully for an external fuel pump off something that already exists. need it to pump out enough pressure for efi. thanks,

any downsides to mount a fuel injector upside down on the manifold? i cannot fit the injectors on the top of my manifold so they will have to be on the bottom with the rail.

checked and found out that thei vac line for the FPR is left open (these TBs are from an arctic cat snowmobile) where is the best place to tap a hole for the map sensor? will i have problems using these TBs? im only going to be using one of these not the pair.

thanks!

infinkc,

The small nipple on the fuel pressure regulator was likely designed to go to a manifold vacuum source, so I would hook your MAP sensor wherever that hose went to.

Lance.

yea i noticed that also, had to be getting a vac source from somewhere for the FPR, guess ill have to do more ...

i have the throttle bodies below, need to know where i should get my MAP sensor reading from? there is no manifold in this case.


thanks!

my engine is air cooled, is there any option for the coolant sensor?

i cant seem to find a small throttle body out there, i need only a single, around the size as a motorcycle one for a single carb engine i want to efi. engine is only 600cc's and had one inlet about 1-3/4- 2". Thanks for any help or ideas what one i can use.
