if you have a stock fuel pressure regulator, 233 stamped on the side of the regulator, a hotwired fuel pump, and a new walboro 340 fuel pump, then the fuel pressure will be 45 psi with the line off-
if you have stock, or bluetop injectors you might think about purchasing a THRASHER 92 street chip-
its only requirement is 45 psi of set fuel pressure with the line off- then you wouldnt have to worry about setting fuel pressure anymore.
do you have a stock regulator or an adjustable regulator?

i just finished installing a kenne bell afpr and a engine bay mounted guage right off the rail. i set the pressure to 42 psi with my friend turbojorge and he hooked up his scanmaster the car was running really rich like 840-870's if i recollect....
i am running the atr chip that came with my car and i think this is the cause of my car running crappy the chip is from 90' i am looking to get one of those thrasher chips hopefully during this week.
maybe the car will run a whole lot cleaner without burning so much gas.
the one thing my car was doing was smoking like a whitish bluish color at idle it would just start smoking, not to bad but unbreathable bad pure gas so my guess the car is running nasty rich. then after it pumps out for a little while the car just stops puffing out of nowhere. my buddy was driving behind me todat and he said as i was letting off the gas or what i say just rolling on idle doing like 80 mph the car also puffs out a little....
could this be related to the chip or maybe the fuel pump. i will be installing the walbro 307 i purchased the other day but i need to come up on a used good working fuel sender. the car right now has stock pump which is not even hot wired.....
let me know what you guys think about this....
is it the chip?

hmm, that chip is not the culprit of your car running extreemly rich-- ive ran that chip, yes i admit it, im a member --
from what ive read from your post, it sounds like the car is running very verrrry rich, you said the 02's were 840-870mv??
was this at WIDE OPEN THROTTLE? or was it a constant 840-870?
Q??
have you been running leaded fuel on that 02 sensor?
when was the last time you replaced the 02 sensor?
long shot here, but when you shut the car off, does the fuel rail hold fuel pressure?? if not, could be a leaky injector, or the fuel pump check valve.....
check to see if it holds line pressure, if not, replace the pump and get back with us and let us know if it holds pressure now with the new pump
the thrasher chip will be better than the pit bull chip you have on the street on pure pumpgas, it wont feel as peppy at first, but set the fuel pressure to 45psi, and then check for knock-
HTH

hey bryan whats up finally someone who can give me some insight on this problem. the car runs the 840-870's at wot at part throttle the numbers are good.
i run 93 octane so far chevron w/techron my partner told me to run some xeylene in the sysyem and then check for knock he said to add only a gallon will this help any.
i have nit changed the o2 but it appears to be changed the cable and the body of the sensor looks brand new the only thing that i did notice is that it has only one cable could this be a problem. i know that my friend is running either a 3-4 cable sensor does this have anything to do with it.
for sure the thrasher is coming hopefully that chip will not have the kickdowns set so hard like this atr chip does. i think it is just to plain aggressive hopefully the thrasher chip will adjust this.
one another note to add to the running rich situation i can only get, get this 180 mph to the tank for me i think the car is running to damn rich whats the deal with this bryan do you think that all of this has something to do with something other then the chip. also i have noticed that when i get off the gas at any mph the car drops rpm's almost to turn off but it does not. but it does it everytime i let off the gas.
when i get on the gas sometimes i have a slight delay before the car takes off almost a hesistation but very fast. i noticed then when the fuel pressure was up to about 44-45 psi then the car did not do it anymore but when i brought it back down to anything below 42 psi then the car started doing it again.
whats the deal with my car i want it to be streetable yet practical at least more practical then my impy ss i mean i used to get 350 to the tank in my impy ss and its v8....
also where is that fuel pump check valve located at so that i can see if there is even one on my car.and the guage holds and reads the same when the car is turned off it holds the same amount of pressure when on as it is turned off. so i guess i do not have a leaky injector... right.....
i really hope the thrasher chip helps out on the scanmaster me and my friend turbojorge took the car up after 3rd gear to see if i was registering any knock then and i was getting 3-4 degress of knock at WOT this is with the F/P set at 42-43 psi and the boost spiking to 15 psi then holding steady at 14 psi the whole way.
also do those thrasher chips come programmed for a 160 t-stat....i wanted to know cause i put a 160 t-stat in my car and it was still running at 187-191 degrees.....

you can add up to as much as 3 gallons of xylene to a FULL TANK of fuel, make sure to add some lubricant like 2 ounces of marvels mystery oil, or ATF-
there is nothing wrong using the 1 wire 02 sensor, the 4 wire heated 02 sensor uses 12 volts to preheat the 02 sensor so that lead from higher octane fuels wont stick as much when the engine is cold- heated 02's are neat, i personally havent ever used one, but they dont throw a code 13 when the 02 sensor is bad { once you get code 13 the 02 is pretty much toast}
and by watching the cross counts on your scanmaster 2.1 you will be able to see how much alive you 02 sensor is- the more cc {cross counts} you get usually means how reactive the sensor is-
02's usually dont go bad unless you are using leaded fuels, my 89 tta was running 12.40s on the original sensor last year, it just didnt have any leaded fuel ran thru it, so it was still good after 12 or so years
the atr chip is agressive for pump gas, once you are running higher octane, you might actually like that chip. adjusting your tv cable will make the shifts firm or soft-
try setting the IAC its your idle air control motor located on the throttle body
the fuel pump check valve is located in the fuel pump tip, where it attaches to the fuel pump pulsator, all inside the fuel tank
that atr chip has alot of timing, try the thrasher chip, you "should" be able to run 17psi of boost all day long with it, you need to purchase a race jace power plate, do a search or post in the forum about what the plate does,.... it really works
yes it is programmed for the 160* t-stat
187*???? hmmm try flushing the radiator, and RAMCHARGERS sells a dual electric fan kit that will help tremendously on the under hood temps
and in the florida heat, you will surely like that fan kit, i think it sells for 80.00 you just got to make it fit, and they do fit our cars with a little workHTH

hey bryan thanks for clearing up a lot of my doubts and ?'s.....
i have already sent out for 2 chips one a 93 oct chip and the other a 100 oct chip both of them are thrasher chips...should be in hopefully by friday or saturday of this week..
also the TV cable as you listed is adjusted for a softer shift, before i even started working on the car it was to tight everytime the car shifted 2nd gear it would chirp them stupidly. so i kep backing the cable out until it felt sort of normal and the cable hardly has any tension on it whatsoever. i just do not like the way it feels when it kicks down it just feels like it is going to do a beatin on my driveline.....
how do you set the iac me and my friend jorge were wondering cause we set up the tps really good but how do you set the iac motor please let me know i really want to know how to do that maybe that might be my problem since i have not even touched that thing yet. all i had done was pull out the little motor and clean the end and the spring with carb cleaner but it did not do anything. and no i did not push or pull the spring out or in...
how do you do this do i have to pull out the iac motor and push in that spring though...
please get back to me bryan.......

dont adjust the tv cable to the point of where it isnt taunt-
perhaps the tranny has a shift kit, and a super servo making the shifts harsh, you might have to live with the hard shifts! i know when lonnie dears did a trans for joe reif here in kc, that tranny shifted so darned hard, it felt like the fillings in your teeth would rattle out when it banged gears!!
anyway you can contact the previous owner and ask what all has been done to the tranny?? and when it shifts into 2nd gear and breaks the tires loose,... what size tires are we talking here?
http://www.gnttype.org/techarea/faq/IACreset.html
or read below-
Procedure
1. Ground ALDL diagnostic lead (short the top two rightmost pins in the ALDL connector).
2. Turn on the ignition (but don't start the car).
3. Wait 30 seconds.
4. Leave ignition on and disconnect the IAC connector.
5. Remove the grounding from the ALDL connector.
6. Start the car. The car will probably run rough and may stall. Just restart and try again.
7. Adjust the throttle stop screw to set the idle to 500 RPM +/- 50 RPM.
8. Turn the car off and reconnect the IAC connector.
9. Turn ignition on and adjust TPS to proper settings. (.42-.44 at idle is typical)
10. Repeat procedure until the 500 RPM +/- 50 RPM in step 7 can be maintained while TPS is at proper idle setting.
HTH-
