Ok, so hers the story. need someone with similar mods with ECU EV52B that has a tuned map that would be willing to let me try it and see if my tuner just sucks ***, or if im really running out of fuel injector.... the car seems to be making good power, but im starting to wonder how good of a tuner he is or if he has any clue what he is doing.... im seeing 106% injector duty cycle, timing seems to vary between 30-36deg. not seeing hardly any counts of knock. just cant explain the injector duty being that high. i dont know what hes doing with the fueling table, my AFR's are showing 11.7-11.9. that seems way fat for a N/A car

my mods are

Stillen Long tube gen 3 intakes
Stillen headers
AAM Test piipes
Tomei y pipe
Tomei single exhaust
mishimoto low temp thermostat
walbro 255 fuel pump

Sometimes injector duty can go high if there's a problem with fuel pressure. With those bolt on's you having should target AFR 13 to 12.8 at higher rpms. AFR 11.7 is almost too rich even for a F/I.

If you "correct" fueling by leaning and targeting AFR 13, your injector DC will drop by 10% approximately. Also, you should gain some HP.

Also I have no idea why you need a wahlbro 255 for a basic bolt on set up... still have stock injectors?

yes im still running the stock injectors, im about to order a set of 440's though. emailed UpRev directly to see if they can be of some help. waiting to hear back. i added the fuel pump because my fuel pressure was low on the stock pump.

on another note... i have set my rev limit to 8k vs the stock 7500. on the stock map it pulls like a champ all the way to 8k on my "tuned" map it seems to struggle at like 7600-8k.

anyone willing to help me out before i go spending cash i might not need to? talked to a couple different tuners in my area none of which will offer any advice without paying to put it on their dyno and tune it.... im willing to do that, but dont want to throw away another couple hundred bux only to find out that they can't do anything for me until i can get injectors...

Whoever told you that you need a 255lph pump for N/A is blowing smoke... same thing with the injectors.

That said, you're probably not going to find someone with a 'matching' setup and a map to share.

i dont expect anyone to have an identical setup, just something fairly close. cold air intake, test pipes and a single exhaust. im curious to see if this guy charged me 700 for tuning and actually tuned something, or just took my money and said here you go... i have the tuner software from Uprev, and i can look at my maps, but i dont know whats stock vs tuned...

If he didn't tune every map (most tuners just tune one or two maps) the un-tuned maps will be all stock values in timing and fueling. You can compare the 1st map with the 5th map to look for potential changes.

im guessing he didnt tune anything, purchased an etune map from uprev direct, and my afr's are good now, but they wont touch the timing. so im trying to make adjustments to that now.

I sent you a PM offering to run your data through my scripts. Offer still stands if you want to at least see what your timing curve looks like and if you are knocking in any particular cells.

Curious how you're monitoring knock with UpRev when its not an available option??

It is available as knock stregth using the rom editor. It is not available on all ecu's.

That struggle seems your motor telling you to back off timing! You've been logging 35degrees of timing? That's pretty high! Drop the values down by 4-5 degrees and take it for a spin.

If you'd like post up a log and your file and I'll take a look at it.
