LSA swap gasser initial startup issues

[waderaces427]

Please see the attached tune and brief log of my initial startup of my LSA swapped Anglia. I have been driving the base LS3 for a couple of years no issues including power tour this year. I decided to add the LSA using my existing tune as a base. The car started right up but was surging and would stall shortly after. I attempted to scale the injectors using ID's website with the 2x stoich method as well as reduce timing. Thanks in advance for your advice and tips.

Flow rate vs pressure does not look correct. If you have a return fuel system and a boost referenced regulator, the chart should be the same pressure all across. Look at the ID chart again for 3 bar (43#)and see what IFR is, then double it. If it is the 61# in the last cell, then make the whole row that number. Why run 43 instead of 58# ? Is the other data correct for the injectors?
You have the option to select a 2 bar operating system--why not use that?
Check the ETC Scalar number and make sure it is correct for the CTSV TB. Did you have that TB on before? If not, swap back to the original til you get it running.

Thank you for the reply, Lakegoat....You are right after my initial post I changed the fueling to 45.88 across the board with 59 psi vacuum off as I am running a boost referenced reg. I also upgraded to 2 bar OS earlier today and now the car fires up and dies. Also, I believe the etc scalar to be that of the ctsv. Last night with the wrong injector data/pressure car would run and surge but after the 2bar upgrade this morning now it dies?

2bar OS uses real VE tables that you have to populate - right now they're zeroed out... Vehicle runs on straight VE for about 15 seconds before swapping over, so without fuel reference to go off of - well it just starts and dies

Thanks! That makes sense and I was able to populate those tables with the transposition of my old vve table. The car is idling now but with a surge so I guess now the rinse and repeat begins using the scanner......I posted another log up top with the car idling but with a surge
