good deal man!!! glad ya got her runnin again!

eh explain the clear flood method in detail please.

89 fox

it is like limp or safety mode that at WOT...it won't send a pulse to the injectors to spray fuel

notch5oh

floor it and try and start it, i hope that isn'ttoo detailed

It's kinda like what they said above. Well, its exactly that, but they didn't explain the how or why, lol. As you know, even EFI engines can flood. And the more you try to start it the worse it gets because the dumbass computer is going to tell the injectors to spray fuel into cylinders that are already flooded. But there's a feature built in to stop that.

If you hold WOT (wide open throttle...pedal to the floor) then the computer thinks something is wrong and it will stop the fuel injectors from spraying fuel. So now the engine will crank but no more fuel will get sprayed in. However, air will still get in. Eventually you will reach a point where the AF ratio is good enough to ignite the mixture and you're good to go.

If it wasn't for that feature, it would be a pain in the *** to clear a flooded engine.

Good to hear you got it started. What exactly is your completed build consist of ? Did you stick with the explorer heads and intake and that #19 cam ?

So far I'm sticking with them. Once I actually get to my friend's dyno and once I get my wideband, then I can actually decide if it's too much or not. Right now I'm just setting up the base tune..

Changing shift points, Firming up the shifts a little more, removing speed limiter, turning off smog pump and egr, suff like that.

So howd it run with the HCI swap ?

Im just tryin to get an idea of how "bad" my car is gonna run with no tune and the HCI installed.

To be honest, i don't really know yet since I havent done much other than let it idle with a few revs. There was a short 2 mile drive awhile back but nothing stressful. It sounds different. It could be the cam, a vac leak, or the bad (nonexistant) tune, lol. A little rough now, but that is expected. The cam is suprisingly computer friendly though.

one trick to smooth out idel is to adjust injector pulse timing
for the different cam profile

stock computer expects stock cam in there so it fires off the injectors
when it thinks the cam is opening. Aftermarket cam will open sooner
and cause rough idel. Thats where "lope" comes from.
