minor hesitation but no knock

[blackdeathtrap]

i think almost got it down pack just wanna know were you guys would go next heres me numbers
blm 127
int 128
fuel pressure 42 at idel line on

wot 0 knock boost gauge reads 18 psi im adding 11 % wot with the chip and i think my translator is set to 4 for wot i havent yet touched timing. if i floor it i barely get any hesitation but if i roll into it so i dont spin tires i get major hesitation then it gos away in 3rd.
should i a add fuel pressur
b put translator to 0 and add more fuel with chip
c add or substrac timing

 

[blackdeathtrap]

so now im down to this point i put the translator to 0 wot set chip to 140 at wot now i have 0 hesitation perfect spool up no timming retard bieng register on scan master but one green light on knock gauge im asuming this is fake because i get it at wot going first to second

 

[Amelio]

so when you set the chip to 140 is that leaning it out? I dont have my reference sheet in front of me to compare 11%+ fuel to 140.

If you did lean it out and the stumble went away it sounds like it was a lil fat.

My car will absolutely fall flat on its face and get a lot of spuddering when it is a lil too rich. Some cars just slow down and huff black smoke or a slight spudder....... Leaning it out fixes that and increases spool up.

do you have a wide band? what are the numbers?

If no wb what are your mv readings under wot?

 

[blackdeathtrap]

no setting chip to 140 is affing 11.2 percent fuel at wot but i put the translator to 0 wich im asuming was causing both setting to creat a rich situation at wot not its pretty much bang on other that one or 2 green lights on casper knock gauge at wot slaming on the throttle from a roll. i dont have a wide band but my lowest o2 mill are aprox bettewen 800 and 850 at wide opens lost ive ever register was aprox 795 ish so maybe a touch more fuel will sort it out maybe a lil timing adjustment im not sure which way i should go

 

[Amelio]

if you lowest 02 readings are 800-850 that is pig rich.......I try not to see more than 815mv my car will fall over spit and sputter around 830-840mv I have found that my car runs bets around 780-800mv at wot......I also need a wideband and I just tune using my SM. To me you sound like you have a very rich tune which can be causing the issue.

What fuel do you use? I leave my timing alone for 93oct which I believe Eric has it set at 18degrees in first and 22 in second I do bump it up with 110 in the tank.

What injectors do you have?

 

[blackdeathtrap]

i ran it today and thats about what im running acutaly at wide open its be around 790 800 im running 91 octane cuz 93 isnt around here

 

[Amelio]

sounds dead on...i would leave it there....as long as you have no knock you can verify if what you see is false by rolling into it in 3rd....1st to second you always may get something from tire spin,exhaust ratlle or your trans shifting. if your clean in 3rd i would leave it alone until you get some fuel in it or alky then play with more boost or timing.

 

[blackdeathtrap]

here my current issue
fuel pressur at wot is around 70 psi 42 at idel running 16 psi on 91 octane if im not mistake timming 26 deg on tt chip
o2 milvolts all bettewen 785 to 830 after adding 12.5% fuel
1/2 guear 1.9 deg timing retarted knock gauge lights all over the place (probly false from wheel spin)
3/4 guear 5.2 deg timing retarted
what should i do im shure this is just fine tunning im thinking pulling timming out of chip until knock gos away or ad fuel adding fuel seems to be helping but how much should i add or subtract of each help please

 

[Amelio]

your timming seems a bit aggressive for 91 oct and no alky.....verify your timming you need to be down around 18 in first and second and no more than 20-22 in 3

you still seem to be too rich and that is just based off the mv of 830 I dont like to see more than 810-815 maxed out and that is still a lil fat in my car. It is hard to get your tune perfect only using a sm but your timming seems too high

back the timming down and then drive...you may find the car get pigish cause its fat then pull some fuel......post up your results once you pull timing then we can go from there

 

[TurboBuRick]

More timing in lower gears, less in high.

why would you set the fuel pressure to 42 line on? erics chips are burned for 42 line OFF...your probably close to 47
70psi fuel pressure @16psi boost is 54 so something isnt right.

id set the fuel pressure to 42 line off, adjust the settings in the translator to match the maf you are using..instructions are under the lid (or in erics instructions)
Look at the chip for defualt timing/boost psi...is the chip burned for your current combo?

Beat me too it! x2, way too much fuel pressure. Your blm at idle is good though so maybe leave it. Anything within 10 of 128 is good though for BL's so maybe still drop a little and see what your BL's do.

Or fix the vacuum leak.

 

[we4Mateo]

Or fix the vacuum leak.

If there was a vacuum leak, the BL's would be high, not @ 127 like his even with the high fuel pressure, I believe.

 

[blackdeathtrap]

if i had a vac leak my fuel pressur wouldnt go up i will try to drop fp then il mess with timming
i adjusted maf translator to 0 no blm is 133 still only 5 more then perfect 128 im guessing maybe fp is way to high but im more then certain i set it 42 line off il check and re adjust your right its way way to how im probly drowning out my engine causing the knock
il also check the chip stock timming

 

[blackdeathtrap]

chip timming is 19 -17
check my fuel pressur you were right i was way out to lunch practicaly 58 psi line off i dropped it down to 42 line off acidently broke end of plastic hose damit but i pushed hose into rubber and zap straped and hair spray

 

[Amelio]

so did that correct the rich condition?

Do you still have knock.

All cars very from one to the next regarding fuel......my car would not even run if it was as rich as yours

 

[kidglok]

after you button it up, unplug the orange wire to reset the ecm. Then plug it back in, start it up and let it idle to op temp, drive it around the block a few times to let the ecm learn.

When you park it again, shut it off then turn it back on, whatever the ecm learned is the right amount of fuel for idle will reflet in the blm once its back to open loop. That will tell you where your at.

 

[blackdeathtrap]

well seems my blm is now 128 int 128 just gotta take if for a drive re adjusted tps to .44 at idel it had went out of adjustment im reset ecu so im not longer adding any fuel at wot will se if i get any knock and go from there

 

[blackdeathtrap]

Im wwell after pulling fuel out of chip and reset ecu and deopping fp to 42 line off blm are 134 still grtting knock at wot but not asviolant im slowly raise wot fuel until i massage knock out fp is a smooth 1;1 raise all the way up to max boost im getting retardof 3 to 5 at wot o2 mill at 780 ish so im thinking either add fuel or pull timing
