well drove my truck to work today i was sweating bullets the entire time hoping it wouldnt crap out on me.drove it there then over to a friends then back home and ran fine.my tranny shifts premature but im assuming being its an e4od it relearning shift points and now with the intake i built for it when its shifts gears it soiunds like a blow off valve almost.it sounds awesome and for some reason the motor is quieter than it has ever been so i assume i had an existing problem.well anyway let me know what ya think about the abnormal shifting and the blow off valve noise

 

I am glad you are finally making progress.

Although I know little about the E4OD, I think the FILP may need adjusted.
I have read the throttle closed and WOT readings enough on here that I should remember them, but I don't.

As for the blow off valve sound, possibly a boost leak.

You do not have gauges installed yet if I remember right.

 

what do you mean by FILP?and nope the gauges are next then the fuel screw

 

FIPL is just another name for the TPS, tis the electronic doodat on the driver-side of the IP with a 3-wire harness plugged into it. You measure voltage between the middle wire in the plug (shove a paperclip in there) and a negative battery terminal, and you do that with the key on but the engine off after engine's all warmed up. You're looking for 1.0-1.1V at closed throttle, 3.8-4.5V at WOT.

 

how would i adjust it?

 

loosen the two bolts that hold it to the IP and turn it

 

I think that the "pop off valve" noise you are hearing is the turbo impeller slowing down,
does it sound like a BIG RIG when thay shift???
Mine does after the new filter and housing...
And you are right, it sounds WAY COOL!!!

 

that is the exact sound it makes people stare cause its so loud

 

OK, you wanted to sell it before.
How much would it cost NOW!
LOL!

 

$5k would take it but it would be emotional lol.i love it once againnow all i need to do is figure out the early shifting

 

Don't do like me, I paid 4k for my 88, spent 2k on paint, 1k on new flex plate and tranny rebuild, 1500 on misc stuff I had Ford do(steering column, fix a short, etc.) 500 on injection pump/injectors, 500 on the front end, and now I'm fixing to have a 1500 motor rebuild, brings up to about 12k in the truck while its probably worth less than the 4k I paid for it, but I just can't bare to see it go, so I keep fixing it, and fixing it. The good news is, after the engine is in hopefully next week if all gos well, I'm oughta have a brand new truck since I've already replaced everything else.

 

haha sounds like me i love this thing for some reason.soon as it gets payed off its gettin torn down though.im gonna get me some p.o.s. and drive it and build this thing up im guessing on a year or two project.
