AutoVE tuning with turbo

12580698 is the 2 bar sensor.

Mike what is your AFR target at 20KPA and 800rpm? What size injectors?

12580698 is the 2 bar sensor.

Mike what is your AFR target at 20KPA and 800rpm? What size injectors?

the target is 14.17. and im using 42lb injectors.

I figured out why, but dont know if there is much i can do while its in SDOL because it refers to the backupVE table on my 98'.

the 20kpa is set low but the 30kpa is set really high because it needs the fuel. So i believe its blending the 20kpa and 30kpa at idle.

I leaned it out at the 30kpa and it started to look ok, but now the car wouldnt move because it couldnt get any fuel from the 30kpa.

Maybe i should make the 40kpa really rich to make up for 30kpa being lean to help out 20kpa? did that make sense? and would that work

thanks

Your in uncharted territory with a 98 computer...Keep track of what you find.. I think you'll have a following if you get it figured out

do you think if i lower the C6301 alittle bit more, to get the idle around 15-17kpa, do you think it would then read only the 20kpa and not blend with the 30kpa?

You can move the key on reading around so your idling in a lower KPA column.

the key? you mean C6301 right?


also, does anybody know of a way to get it to read the mainVE table instead of falling to the backupVE ?

thanks

I had used this spreadsheet to tune my Injector Pulse Width table B3701
http://ls1edit.slowcar.net/injectoroffset.xls

When i would change the table back to stock the car wouldnt even idle because it was so lean, so i thought maybe if i richen up the VE tables it might work. So i had to richen those idle areas by double. Now my idle is at 12.4, better then 10.8. So im going to try and lean it out some more. I also noticed that im going to have to richen up the rest of the VE tables by 15-30% just because i changed the B3701 table back to stock.

Should i use that spreadsheet or just keep that table stock?

My IFR table is tuned correclty by using the other spreadsheet and i havent touched that during tuning.

I did a log on a Forced Induction car today that was tuned with Vcmsuite. When logging its MAP only went as high as 105 and all values below it seemed to be normal values at that rpm and speed etc.

Did i use the wrong pid?

The car has heaps of power - logged up to 1.36g/cylinder at 6000rpm

I the car probable just has the stock 1 bar MAP. 105 kPa is all it will read. You need to put a 2 or 3 bar MAP on it to read boost. Most likely it's using PE for fuel enrichment while in boost.

The owner said it had a 2 bar map sensor installed. Its been tuned with VCM Suite. So does that mean it cant be read and edited by EFIlive??

Does anyone know what i will need to do to use our system to tune the car? Will it be editable or will in need a full reflash?
