Thanks.

[Angel67]

Pro tuned on map 2 and running maps 2 and 5 for daily. Yes 3.5 Bar TMAP.

[najin23]

what psi are you running? map 5 tops at around 19 right?

[Angel67]

Making just under 400bhp at around 17.5 psi. Not sure what map 5 would top out at with better fuel.

Terry, was going through the 1st page. I have played around with my db settings an have gotten clean logs and boost on target with FF learning down to 88 and also as high as 109, depending on d.b. settings used. Is either one more desirable than the other ? Timing, fuel, boost, trims, etc look good with either settings.

[Terry @ BMS]

Have one of the logs to compare? FF is going to move around as weather changes, so that isn't an issue.

[THE BEAST]

No I don't. Deleted all of them 2 days ago as jb4 mobile was on auto log and had way too many logs that were causing confusion. I will start some fresh logs.

[THE BEAST]

Even downshifting it was capturing logs. Terry, for duty bias tuning, 3 pulls are needed ? Or more or less before making any changes ?

[Terry @ BMS]

Just one normally to evaluate it is good enough.

[THE BEAST]

Cool, thanx.

[THE BEAST]

Generally speaking, hybrids and port injection. More spray = more timing drops ? Or vise versa ? I have read up on p.i. affecting timing.

[Terry @ BMS]

Shouldn't have any effect either way. But more boost = more timing drops, generally speaking.

[THE BEAST]

I was reading up on pi wetting up the plugs. Also some guy was getting timing drops and he swears lowering FOL was the fix for it. Coincidence ?

[THE BEAST]

Or how about pi being an inderect cause ? Is that possible ? Say its not dialed in correctly, could make the cylinder run too rich or too lean and cause timing issues ? Or still NO ?

[Terry @ BMS]

Not come across any evidence for it.

Question regarding these settings for hybrids running JB4 and custom MHD BEF, PI, Fuel It Stage 3 etc.

Should I still be locking the FF and setting duty bias? My tuner did not mention it and I am really getting the feeling he is not a fan of tuning along with the JB4. He seems to be more focused on MHD tune only and I don't want to drop my JB4 and JB4 PI controller.

Hello,
I'm getting a strange surge and sound (almost like a siren) under low or no turbo load (2500-3500 rpm). Sounds like my BOV maybe opening and closing partially. Any thoughts?

Thanks

[Terry @ BMS]

If you need tuning help post a JB4 log of the issue and details in the support area.

Hello, I have a problem with pure stage 2 turbos for n54, is this where I should ask my questions? I do not want to ask things in a tread that has nothing to do with the subject

[Terry @ BMS]

You could, or just make a support thread in the support forum with JB4 logs and details.

[emiliano1]

Thanks terry, the problem I have is that I have a lot of lag, in second gear at 4000rpm I accelerate it and it takes 2 seconds to load, when I change the same speed, it takes 2 seconds to reload pressure, I think it was better with the turbos stock ... If you do not go in this tread please move it to where it corresponds terry.
Thank you very much.

thanks
you means flash map e85 hybride on pumpgas with meth is it right??

Thank you very much.

Just post a log of the issue along with mods and details in the support forum and myself or Steve will check it out.
