Topic: split second ftc-1

[sharpxmen]

you should try to get it to work right with the bypass open and no ftc or enricher or large injectors, skipping over this step will just make it almost impossible to tune. Just my opinion, you're trying to adjust the readings and inputs to the pcm and fix the problem at the same time.

they sent me the wrong instructions the 97 ones were right.

i can watch the linkage. when i stab the throttle it goes dead lean. rod is pulled back it only falls forward if i hold it there and let it shut off or all but shut off. just like if you would have a cold engine with a carb and held the choke wide open. if you stab the throttle and hold it at say 1/2 to 3/4 throttle it just feels like you turn the key off and will shut off unless you let off quick and say feather the throttle. this is how it works. at 2000 rpm it does the same thing if i hold it there it all but shuts off untill the rpm gets under 2000 or over 2100 or so. i am sure the butterfly is open when this happens.it only falls off when its about to shut off or when its  running so bad that it cant maintain vac for a time. you have a ton more experience with this stuff but i dont see a problem with the way the butterfly is working. belt off with vacuum  to the actuator should be the same as if i wired it open,right? if thats the case i will pop the belt off tomarrow

i don't know if it's the actuator or not, what i'm saying is that if you lock the bypass butterfly open and it does the same thing (the 2000rpm problem) then it's not the valve or the supercharger or the emissions or the pcm (you name it) it's something else and that's where you have to look (maybe it is the intake manifold, the injectors angle or maybe the fuel rail setup, i don't know what exactly but you need to find out). There's no reason on even trying to go passed this point unless you're sure you can fix it and tune it at the same time but i doubt it. all this is with stock injectors and without the ftc or enricher

anyway, that's all I got, can't think of anything else

about the instructions:  what's different between the 2 sets?

add ing 1 wire to cam sensor signal. ftc couldnt see rpm without it. been talking to split second several times this week. they want me to put bigger injectors back in it.  they said my map needs to be very close to theirs and oems were set fully maxed and still couldnt deliver eniough fuel. while using their map it would not do anything but idle and it was rough. i couldnt even pull out of my driveway without slipping the clutch and couldnt even shift to 2nd gear without slipping the clutch and wideband was at 15.50 to 16.00 the whole time. they are leading me to believe that i need big enough injectors to run at their base map settings. they said their map is for 50% bigger injectors soooo... at my stock fuel pressure how do i find injectors 50% bigger and do injectors made to run at lower pressure work well at higher pressures? what would you recomend as far as the best option for injectors  i think we discussed this before but do you have any source of info that would give me an oe application for injectors that would give me what i need. i know

[moparstroup]

that this is a different approach but he said he will walk me through this till we get it. i want to give him a chance.

since you got 30s means you'll need 45s, i'm curious to find out how it works. check Accel's website, they might have some equiv table where you can get the oem application which would have something that size.

[moparstroup]

my oems are 30's at 47lbs pressure so i need ones that are rated 45@47lbs fuel pressure right? didnt see anything on accells website. any other ideas

[moparstroup]

what do you think of a bosch 42 lb ev6 ford racing injector ebay 40.00 ea. 42lb at 43.5 lbs fuel pressure. 15.9 ohms resistance

i would just ask them for the rating rather than trying to guess, they know better what's the flow their system is built for, just clarify with them at what pressure should the rating be at.

ok working with split second is like going back to page 2 of this thread but i will do what they ask. the putterfly thing, were you looking go see if the butterfly was opening all the way or if it was falling back closed. because i am sure it is not releasing thus causing the lean spot but what if the actuator is not pulling it far enough? it seems like the tip in deal is like when the throttle plates open up the s/c stuffs too much air in causing it to go too lean. i think we discussed this before and you didnt think that was a possibility.but could that happen if the butterfly malfuntioned

sharp can i use 4.0l tbody with its iac and just swap connectors or do i have to use a 2.5 one and swap it intp 4.0 tbody. my 2.5 one is sticking and ive cleaned it but it still sticks and i have a 4.0  tb with one in it.  and the butterfly deal. still wondering  if  you were thinking that it wasnt opening fully or closing prematurely.

with the 4.0 IAC will idle high, might go down but takes longer to get there. you can use it but won't be proper

Hi Mike,
 
>>>i saw a fuel pressure dampner on your site
 
FloScan Instrument Co. does not manufacture nor does it sell "a fuel pressure dampner". In fact I doesn't even know what one is.
 
>>>i realize your site says for marine use but i assume that for liabillity reasons.
 
No so. We would love to sell systems for wheeled vehicles but when used in that application they are grossly inaccurate.

after waiting a week for a reply on the dampner that they have on there site this is what i got.

its called pulsation dampner

he's talking about flow sensors, there's nothing to be inaccurate with the dampner
