heres a 38psi pull with he351ve

[blucas1984]

got most of the bugs worked out of the setup now, i need to put a new alternator on the car. it cuts in and out makes the car run pig rich when it cuts out as you can see at the start of the log. im running out of injector need some bigger ones (bosch 1600cc). what do you guys recommend ? i did put the second fuel pump on a hob switch so it works now after the log.

Couldnt open the video for some reason.

umm..you're going to melt a piston with those AFR's...and your airflow #'s are inflated alot..... the car seems to be moving along pretty well but i'd be addressing those AFR's pronto..

Video??? ...its a log

I turned the pressure back down a little , i got my water/meth hooked back up i think i mit run just meth to add more fuel till i get some bigger injectors.
heres a pull at 32-33 psi.

Video??? ...its a log

Lol thats funny

Relying on meth injection is risky business when you're using it just to fight knock....(I do it..but i condone that its risky and am fully aware that i am probably going to blow up because of it some day) ... Relying on it as a primary fuel source is rediculously more risky .... The only way i'd ever ever ever even consider that is if you have direct port meth injection... You spraying a meth nozzle before the TB and expecting it to equally distribute between all 4 cylinders to provide a constant AFR is a dream... I wouldn't count on that at all..

afr's in your 2nd log are more acceptable... room for tweaks but thats WAY safer than the first log...

Holy high AFR's Batman!

I would like to see this thing do a pull from 3000 rpms? How is the response of this turbo down low? Do you have the variable controller hooked up or just all the way open?

 

[blucas1984]

as soon as get the new alternator on ill get a full pull in 3rd. its alittle slow down low till you 10 psi then it goes. im just using a wastegate acculator that pops off at 18psi to switch to the big side.

is that wideband accurate? i have never seen somebody use one of the presets on aem and it be accurate including myself.

 

[blucas1984]

no, its off if it says 14.0 its 13.0. what did you adjust to fix it ? ive been going off the gauge.

Dacowgod why do you say my airflow #'s are inflated alot ? 65lbs/min should be about right for the turbo

 

[dacowgod]

Its inflated because you're SD table is north of 100% by ALOT which means AIRFLOW is inflated...its rare you ever bring the SD table over 100% as its pretty impossible for a pump to be more than 100% efficient (The engine is the pump here) ..you are inflating your SD table to get your AFRatio to be where you want it, rather than adjusting global fuel to get your AFR's where you want them and having an SD table that looks like an efficiency table . ... ....Your airflow is likely reading 10 percent or more high and you're near 60-65lb/min not the 70+ peak you're reading...

In my opinion You're tune is all whacky...though it may work perfectly fine because all that technically matters for a good running car is the end result... not how you got there... ..its just not standard practice and some of the #'s you're looking at from ECMLink that rely on the misinformation are not going to be accurate because of this...(i.e. boostest and Airflow) in this circumstance..

hello Cant open your file . But if you are looking for larger injectors Give ma a call or PM me . I acn supply 1680cc 2200cc High Impedance injectors for you and most anything else you need for your fuel system
Thanks Frank RCI

 

[blucas1984]

That makes sense , on why the numbers are inflated. i did what worked to make the car run right.

his boost est is way off from what the boost actually is, it thinks you getting alot more air then you actually are.

to fix the wbo2, set your ecu pin you have for your wb, to linwidebando2, then capture it.

once you've captured it, go into the preferences on linwideband on the data-log screen, change to voltages there to match.
the p0-p4 corresponds to the little knob on the back of the gauge when you turn the gauge on it should say a p0 p1 p2 p3 or p4. p0 is where you need to be i think, then put lambda .75 and min volts .5, go down to the next lambda and put lambda 1 and max volts 2.35 save and try it out, it should be really accurate. you may need to adjust it a little bit.

assuming your afrs were off by a whole there as well and it was around 11.5 ish i lowered your ve table. fix your wideband first before trying it though.

what we are trying to do here is adjust your ve table to make your actual air fuel ratio replicate your target air fuel ratio
