MRLILGUY fuel pump....love it !

[TRU-BOOST]

well after many months of waiting and fuel cut, my pump came from Jon yesterday. i did the install in about 30 min. total. it was super easy ! the car fired right up and ran perfect. the temps were about 42 degrees and i got no fuel cut at 20psi. i took some logs with the DH for you guys to see. my afr's are low 11's high tens. that impresses me considering the temp, my mods, and boost level. check it out !!.......
4th gear pull from a roll. i spiked to 23 held 20..16 @6K


4-5 gear. 5th is clearly leaner but still @ 11:0 !!


3-4 and a little bit of 5th.....all 10's-11's sweeeeetttt !!


thanks a million Jon ! i feel much safer pushing my car this hard now. now i will have the fuel to keep up with my big wheel k04 from PG (it is on the site now)!! i am waiting on a CS downpipe to do the install of both. oooohhhhh yeah !!

you realize your pulling timing right? Thats the reason your running richer. Log timing with your kr

[TRU-BOOST]

do you mean because of the knock retard ?? my car has done this for as long as i have had my DH to check it. i will try to log timing next time.

[ptperformance]

I was going to ask about that knock. Why so much knock? That can not be good with a DI motor.

[Laloosh]

i hit .x every now and again. But my timing doesnt even get touched. BAck in teh day with the pos standback ive hit figure as high at 6 and saw my timing plummet, hence while im telling you about this

[TRU-BOOST]

here is what i logged today knock went to like 2.5 . i have seen mine go over 6 before. i think it has to do with a lot of stuff like .... the low temps. today it is mid 50's so and i see lower knock retard. i saw my 6's in 30 degree temps with 20+psi. i think the bad winter gas blend we get here in chicago adds to it also. i really dont know here is the log.
what do you think laloosh ? i dont have a log without knock to compare it too. does it look like its pulling timing to you ??

[Laloosh]

your nto pulling timing on that run, however i can almost say this with 100 percent confidence. When you record stuff around 5 and up, it will pull timing.

[TRU-BOOST]

well that is good to know. it is pooring like crazy right now or i would go gather some data logs. i will have to keep an eye on this. i honestly think it is a combo of temps/gas.
within a few weeks i hope to see no higher than 2.0
in that cas with full timing look at those AFR'S !! low 10's. and that was spiking to 21 held 19 falling to 16 by 6k ! i didnt show the fuel pressure to simplify the graph, but it held about 1600+ in the high rpm. the was a spot towards the beginning of the pull when my DI pressure went into the low 1300's then poppedd back up.
