yeah, but I always come up with different tables and how much they actually flow on our fuel pressure. If someone with these injectors that has a tune that is working great could just give me their ifr table that would be so much easier.

no, you give man a fish, he'll be fed for a day, you'll teach him how to fish, he'll never be hungry again. i'm not being an ***, i'm just trying to teach you.
i'll give you a tip: svo 30s at 3 bar come out to about 34.5 at 4 bar. use the spreadsheet and you should see it for yourself.
if you're really lost, i'll show you how to do it step by step, but that's the last option.

43.5 empirically checked, i had a fully tuned car, put in new injectors, put in a new config based on 43.5->58psi conversion and low and behold, LTFT table is perfect, just as before. if the injectors were misconfigured, it would show the whole thing either rich or lean, but i was just under zero, just like before the changes. might not be scientific, but it would be a huge coincidence if it happened to work out like that on random. just my opinion, your milage might vary, no animals were hurt in testing of these injectors

well this is the thing, my LTFT table is all zeroed out, but I feel as though my car is running really rich because I'm only getting about 10mpg and I can smell the fuel. So I'm completely lost, I though maybe if I changed my IFR table and see how the ltft change and play around with it some that I could probably bring up my gas mileage a little bit.

a wise man once told me not to mess with the IFR's unless you have aftermarket injecotrs. if you do, then the spreadsheet in the sticky will work very well for you. If not, then its all ve...i think

ok, for future reference, so i don't ever have to answer this again:

Yeah, that's about what I have them set at. I need to take a look when I get home to be sure, but it's pretty close to what I have them set at. humm.....I guess I need to look somewhere else as to why my car is running rich at low rpms.

that can be a bunch of reasons, you can have a miscalibrated MAF, your RAF tables might be off, or you might be just measuring it at a wrong time (i'm not kidding, read the 'how MAF really works' thread. temps, thus massflow readings change as car warms up, making computer think it needs to dump fuel. i got the same problems, so i just leaned out the VE table in the idle region.
