ok i just got my egr tube replaced, and i was going throgh and monitering pids and looking at random data, i noticed that im runnin pig rich, the car is slow as faack, fuel trims are all trying to lean but cant cus they are maxed out, soo i reset keep alive memory,drove through a drive cycle, it had good power untill it relearned its fuel curve. im woundering if i should do a tune up, my plugs got all 86k miles they are a little black, i also noticed that my knock sensor is pickin up some of the header rasp, and retarten my timing, the trans fluid has about 45,000 on it(auto) it may be a little burnt, but im at a lose, need some help.

Your plugs are black because of your rich condition.

Its odd that the knock sensor is that sensitive...

New plugs def. wouldn't hurt...are your 02's plugged in?

Def new trans fluid if its burnt, and a cooler.

yeah all my o2s are in and switching, im workin on a trans cooler, will go in with the lyntech parts and turqe converter when the slush box fries, already got them but i can fix what aint broke( i mean im lazy as hell). how well do those iredium plugs work? i wounder if i should throw a bigger camm in and see what happens, that would be funny if it worked..." hay checkit out my car is stuck on rich, so i made it open the vavles more to lean it out."

Well iridium plugs would be pretty pointless, I would stick with the factory plats.

Do you got a tune or a chip on that car?

I would throw the trans cooler on there when you do the fluid change.

no tune as of right now, cooler is done, finished at work today, found the problem, when the derby car was in stock breathing form, it liked mid grad gas( specialy when it was cold out) i filled up with the 87 octane and drove around then hooked up the scanner, it seems that the placement of the cat in the system and the fact that the o2s have no cat inbetween them , the motor was getting to much of the unspent fuel down the exhaust then backing up at the hiflow cat (after the header) so the computer thaught that the cat was not warm enugh so it dumped more fuel, now the octane is lower and it dose not see this as an issue it thinks the cat is warm and goes into closed loop, .... im a dumb ass, im sposta know this crap, i only studied it for 2 years, but im still gona need a tune(reflash,or chip) need the 500 bones to goto hitech.

Bah buy an xcal2 and disable the 2nd o2.

[focinite]

what is a xcal, i want to get the tune fer the trans mostly, after the converter goes in im gonna want more line pressure to help with slipeage i also need to go faster than 112 mph

SCT xcal2, its a hand held tuner that will allow you to change your top speed, advance your timing, firm up your shifts, disable rear 02, disable egr, change idle....

You can get one from focussport for like 379$ shipped, I don't know what all comes on it, but, I know you can get custom tunes for them.

If you look around, you can get them for 250-300$ for one.

Being that they are a hand held, they do not depend on your ECU code unless the tune loaded on it is for a specific ECU code.

There was also a kid on FJ selling a 4 bank chip for an auto...

It seems if you buy your own xcal2, places charge you 79$ to add a tune, and, I think you have to ship it to them.

I figure a generic tune should be enough for me until I get cam gears and a few toher goodies where I would want to get it dialed in on the nuts.

i went to ford tech i should know this crap and not to do dumb things as such. the higher the octane the slower and more even the burn, i was using to high of octane, it didnt burn fully , exauhst vavle opens , spews unburnt fuel into cat, cat gets loaded, backes up, sensore reads , checks other crap, figures car aint warm, still in closed loop, dumps more fuel, and continues to do this. i went to a lower octane so fuel burns fully, now this woulndt be a prob if the focus had a air pump, it dont, so it has to do other things to keep the cat alive. a tune would tell the computer that i dont have a cat, or egr and problem solved.
