I thought you said you used JohnBradley's values for the latency so my assumption was if his were wrong and JohnBradley tuned his then mine would be also but now I see you aren't using his. My issues aren't tune related, they're hardware, something is going wacky with my car and I'm trying to pin point it to fpr, fuel filter, fuel line, or injectors and possibly map sensor...I used to say I was blessed with a smooth running car, now she's showing her true colors *sigh* I know you're busy tuning so didn't want to bother you with stuff non-tune related. It's some fuel distribution issue. See -

if Curts issue wasnt hardware it was the SD tables.. specifically the sd map ve.. as it plays a massive roll on what the fuel map represents.
if not that then injector related.

 

its the original Injector manufacturers recommended voltage settings modified.. he might share with us what hes found works best on cars, and yes i trust his settings so i do sometimes use his numbers as a base starting point since hes kind enough to contribute, but as you know every cars different and some cars may start fine with one Cranking ipw setting warm, then another not.. so every cars unique. One car may want this latency voltage at idle.. another this.. so its standard procedure to log airflow hz, trims, etc for each car no matter if its the same displacement or not.. as they can vary and breath different.

ill check the thread out.. im on aim dont be afraid to contact me. just because im busy doesn't mean i wont still talk.

 

It wasnt the SD settings, it was a math mistake on something else simple. Like I said its sorted and he has a new map to match the mods.

 

injector scaling lol. the extra engine displacement changes confused him probably. right? i dont think he cares if you post what it was. everyone makes mistakes.

 

New SD map fixed drivability and cold start a lot, BUT car is still doing exact same thing, shooting to 13-1+ at high rpm, not a ROM issue at all.

 

Curt, I take it have have not messed with any part of the fuel system since installing the FP Black correct?

 

I figured out my issue...two almost 100% clogged injectors, 1 was about 60% clogged, one was clear. The two clogged wouldn't even pull fuel through *sigh* They're being overnighted to FIC. UGH, f'in e85 *double sigh* I got lucky, damn e85 showed no knock...keep an eye on that wideband gauge from time to time guys!

 

Not at all but the good news is that it is fixed! Not sure how but it holds 11.5 from 4-8k perfect in 4th, had nearly the whole car apart, battery disconected for two hours, inspected everything and it flys again, I'm happy at this point.

 

This may sound stupid but did u ever think it maybe the wideband sensor thats bad?same thing was happening to a friend of mine and he did everything..found nothing then changed his sensor n it was the problem.

 

I was gonna say wideband sensor or injectors..Good luck Curt!

 

Glad that your car stopped being a *****, now lets see some numbers from this beast with the black!

 

This sounds very familiar... still sorting out the issue, but it seems to be improving. Initially seemed like a scaling issue. If I scaled the injector size higher, it would drive better, but the A/F ratios refused to get richer at WOT. If I scaled the size lower, full throttle improved, but at the expense of driveability. Also running FIC 2150s

Damn it...my injectors weren't my issue *sigh* They're back in and same issue, damn it all to hell

 

Try scaling the injectors incrementally smaller and report back. That is exactly what I had to do. Also with such a larger injector I was having issues with tip in throttle being too rich, so I dialed back substantially accel enrichment and that improved driveability.
