    Vss signal loss issue

    i can't find the article sent to me from a bad mlps. but it stated that it caused all kinds of wierd issues that were very difficult to diagnose. ford had a tsb on it because so many dealerships were at a loss on the issues from a bad mlps. my mlps went out and my 4low quit working as well as...

    intake porting "Big Dogs"

    yeah, they make no difference in performance on the jet ski's but are required by law to suppress a backfire, kawasaki had a HUGE recall because they didn't put them in at the factory........i can't tell you how many of those i did....ive seen a few motorcycle engines with them as well as land...

    intake porting "Big Dogs"

    what do you mean not right at the cylinder? those go right on top of the throttle body's, each cylinder has its own TB. not restrictive at all those are off of a yamaha fxho, five valve per cylinder engine, capable of over 14K rpm......

    intake porting "Big Dogs"

    ......cuz if it works on a golf ball, its gotta work on intake tubes, under vacuum or boost right. like a fighterjets skin, like a sharks skin.....like a roughed up bottom hull of a boat that handles so well........air fills the voids creating its own perfectly smooth surface...

    Best long tube header for under $1k?

    im running the ford motorsports stainless shorties for the f150/bronco and couldn't be happier. port match is perfect for the gt40's, bolting them on the block was no issues, minus a little dipstick finesse..........and they have held up the test of time, through all my offroading, beach trips...

    Vss signal loss issue

    do you have rabs? and id you ohm out the wires from the vss to the speedo to see if all is well? do you have any check engine light? abs light? that sensor is the only thing that reads speed unless the lightnings are different. so if you have a new sensor, connector is clean, wires are good, you...

    Aftermarket Cam idle woes

    got the computer back from having the capacitors replaced, took ecm apart to verify quality, sprayed both sides of the circuit board with battery terminal protection spray, put it back together after it dried and sealed the rear port with foil tape. removed all wires from the 60 pin and cleaned...

    Vss signal loss issue

    not sure about the lightning, but i think the path goes from the rear diff, to the rabs module, then speedo, then ecm, sounds like the computer thinks your already moving and sends the trans into the appropriate gear. not sure why its jumping at idle, have you pulled the vss sensor out and see...

    Best long tube header for under $1k?

    yeah i wasn't sure if you bent them one at a time or what, you got lucky they both bent and not the weaker one first. with them spread out, now you can work on the x pipe
