New Fuel Pump VE Try 2

[Lxjoshxl]

Running pretty good I wonder if im at the most capability of this motor. I noticed ever since the intake injectors etc I get random pops getting into throttle is doesnt show as misfire or knock but sometimes it does pull timing randomly getting into the throttle from slow speeds probably normal. Also Noticed while not in SD My converter takes forever to lock up once it reached the lockup speeds that I have defined in the tune 48mph etc. Siruis been a great help with all this man ive been looking at the comparisons trying to learn too on my end.

maf 3 run 1.hpl

What's the tire diameter across the treads?

[Lxjoshxl]

measure? or the aspect ratio 265/75/17?

[gtstorey]

Measure, preferably by circumference divided by pi.

[Lxjoshxl]

Top is 8.5in width circumference edge to edge about 32in so decided by pi 10.15in

[gtstorey]

Look up the definition of circumference.

[SiriusC1024]

It's ok. 32 inch diameter.

My bad I totally spaced that I don’t have a floppy tape my kids took it lol I could always use string

[Lxjoshxl]

I feel like if I’m getting that pop/skip when getting into throttle it’s gotta be these damn injectors, it doesn’t effect my driving but sometimes I do notice it it’s like two step anti lag on a turbo car lol

If it's an audible pop it's most likely a lean tip in pop in the intake.

[SiriusC1024]

See if this helps things. Most concerning is the popping in the intake.

- Applied BlueCat trans software with factor 1.6 to shift and lockup. Shift pressures up. Raised the min duty cycle for the torque converter.
- Spark and knock adjusted. Got rid of burst knock.
- MAF changes based on log MAF 3 run 2.

Was thinking burst knock? AFR is tracking. Only transient is at throttle close.

Actually, yes those damn injectors may be it. Look what they did to the VE table lol. There are times where it is leaner than it should be, so fueling had to be brought up. Were you getting that effect during SD? MAF can gloss over things, but the VE table will make corrections more exactly.

Typically it's injector data or transient. Or just crappy injectors which kind of ties back to the data.

[Lxjoshxl]

Yes it’s an audible knock sounds like it comes out the headers but could be intake Like you said. I looked at blue cat thread awhile ba k when I first got my motor swapped I hear people love spreadsheet to apply changes. Do you think Spark advance is maxed out on this? Also motor has trouble starting with sd off adjust the braf table?

[Lxjoshxl]

I called deatchwerks saying these injectors are not working out at all problem is it’s been over a year when I bought them build took long then finally put them in I mean it’s not a huge issue, maybe it could become worse I’m not sure. I know another guy on here said he had the 44lb ones and his VE table was way richer than mine

Problems during cranking or after the motor is running?

Yeah I hate those injectors. Gen IV injectors would've been much better.

No problems cranking. Just when MAF was re Enabled I notice rougher starting in the cold seems like I’ll have to adjust the throttle blade a smidge. It sucks because I bought these June of 2022 $450 so that year warranty is up. It runs awesome besides that random tip in throttle popping or knock it’s mainly High MAP Lower RPM. When PE hits it takes off but runs fine other than that too.

[SiriusC1024]

Ok. I've put it in hybrid dynamic airflow like factory. MAF was pretty much done. Top end of MAF, where it was a little off the last couple logs, will still be able to be adjusted. VE is now referenced for throttle changes, MAF for steady. See if things improve. If not then we'll run it pure SD and leave it.

Little tip for you guys. OP if you can get it to pop and note a very specific time stamp in your data log where it does it, Sirius, apply 10-15% over in your VE at that specific area, could be enough to fix the lean pop. You're overcompensating, and some of the time the trims will be pretty negative moving through there, but it may fix the problem.
