I just wonder if its possible to have 2 tables to controll the lm7 with 2 diffrent banks? or how is this done with 2 lambdasonds? trying to make sense of the new emu pro before getting my car ready to start ![]()
Hi,
You have several options for setting it up.
For VE, you can use one table, two separate tables (one for each bank), or one main table plus a bank 2 correction table. You also have to assign cylinders to banks. For LM7, you would assign odd cylinders to bank 1 and even cylinders to bank 2.
Lambda sensors are assigned separately to specific cylinders, not banks. Lambda 1 is for cylinder 1 and bank 1, so itās assigned to odd cylinders, and lambda 2 is assigned to even cylinders.
yeah i have seen it but havent found how to get the separate tables, its setup with bank 1 - 1,3,5,7 (lambda1) and bank 2- 2,4,6,8 (lambda2) with injectors and lambdas
would it be recommended to use something else then map/standard pressure to map a N/A v8? using dbw and have a Vag 3bar mapsensor, but since it wont build boost pressure do i need to map with TPS?
So its only a correction based for the lambda2? or have i done it wrong ![]()
this is my base map i have tried put together
e91 lm7 startmap.emupro (31.3 KB)
It has nothing to do with lambda corrections.
Closed-loop fueling corrects each cylinder, regardless of how the banks are set up.
Two VE tables let you calibrate differences between banks.
So if one lambda is making 0 correction and the second lambda is +5%, you can adjust the second bank VE so the lambda is on target without extra closed-loop corrections.
If you use āBank 2 baseā mode, the second table is a base table with the second bankās VE value. Itās an absolute and separate VE value, not a correction.
So in this mode, you should start with both VE tables identical. You can save your Bank 1 VE table to a file and load it as the Bank 2 table.
But if you are tuning from scratch, you should start with a single VE table. And after most of your VE table is done, you can enable the second table and do fine-tuning to make the banks even.
okey thanks alot
then i know and can get this done when the car gets on the dyno
isnt used to how to make the tables, but now i know how to make it a 3d table like base 1:D
You might want to check the EMU PRO software guide.
Itās available on the product webpage and explains how to use the client software.
You can also right-click inside the table, save it to a file, and load it into another table. This lets you copy a VE table from bank 1 to bank 2. Including axis configuration.
