Ok, good. I think we are on the same page and why I have been struggling so much. Perhaps I took things a bit to literal or I'm slow. Either way! I'm sure I have a transient fueling issue from...

Correct, if I locked spark and IAC to attain a stable lambda, other than pig rich, I found it very difficult. Always cycled between lean/rich. Added VE rpm/MAP got worse, removed VE, same thing....

smokeshow - Flattening out VE appears to make matters worse at idle and horrendous if I actually try to drive "lightly" such as going up or down the driveway to garage. I agree that the oscillations...

I took another log. Cheers!

I copied injector data from the ID spreadsheet. I interpolated for the 3bar (300kpa) flow values through excel since there is no direct 300kpa listing.
With that, I've tried to mess around some more...

Yes, I run at 3 bar (43.5psig) with a boost referenced return style pressure regulator.
No catalyst with long tubes. I did remove the retarded timing from the "warmup portion" at one point,...

Hello all. This has been plaguing me for over a year and I can't seem to nail down my issue with idle quality

Tune - 124094
Log - 124095

This is a stroked LS1 with a LSA supercharger, over...

I think this might help if my injectors weren't already up against their duty cycle limit. Since I am running so rich and likely have tuning issues.

Having a fully operational pump has helped a...

Sharp! How does your VE table look? Ridiculous as mine?!

Cool. Was looking for more along the lines of folks like myself with cathedral port heads and adapter plates LS1. I mean, e-bae listings have sold hundreds of these adapter plates, where did they...

Correct me if I am wrong! EDIT: Also, forum does not allow for the degrees symbol so they will appear as "?" EDIT

Gen3 24x crank = 15? per ref period (360/24)

15-20? would then be 1-1.24 ref...

Cool, glad to hear another person confirm that should be done. Any guidance on what degree the change should be? I just added and subtracted until a saw a large change and backed it off to "the...

No problem there, just was curious.



10-4 on that. I could turn out that piece and figure out a method to tie it down.



Maybe my memory isn't serving me correctly... I recall having 4...

I agree with you. I want a MAF. Hence why I have pondered moving to a PCM that could handle this.

With that being said. If I were to take the card style maf, install into a larger tube (say 4")...

I assumed this setup would over flow the stock maf and the PCM would take no values over 512 for g/s over frequency for the MAF table. So, MAF-less it is. I would prefer to have one but that will...

I have stock LS1 bore, almost. 3.905" so I am pretty restricted hence the small bore LS3 option.

This build isn't going to be anything trophy worthy, just decent reliable power always on tap for...

A fair question. I don't disagree with your statements.

Answer, 3 bar is what came with the ZL1 lid. Didn't see the sense in buying another sensor to get this going. With that said, since it is...

TTT?

No one else working on an LSA LS1 swap? :confused:

Update!

It has been a while. With the car up for winter and another vehicle added to the fleet the slomaro took a back seat.

Short of the long is the new Aeromotive fuel pump was defective....

The short of the long - No.

Car is up for the winter. I do have an Aeromotive A1000 external fuel pump from another project... and my tank already has a sump for external. However, I think one...

That is something I wanted to mess with but haven't since I have been having fuel system issues, do you mind disclosing what value worked best for your setup?



Got it straight from Summit. I...

I did change the filter to a nice unit, no improvement was seen from that. Two different styles of filters, both decent quality the 2nd larger than its predecessor.

I went ahead and dropped the...

Yeah, that thought crossed my mind, I was planning on moving the pressure transducer to closer to the pump to see what the best output is.

Right now it's 3/8" line to a -6 into and out of both...

I am running an Aeromotive 340 Stealth. 10ga to the pump (at the top of the tank). -6an supply and return lines. Aeromotive A1000 EFI regulator with an Aeromotive 12311 10micron filter.

Base...

Well, I installed my fuel filter and still had the same severe fuel pressure drop. I decided to investigate the fuel pump wiring as it is an older vehicle. I found a large (2+VDC) drop on the...
