hi,
i'm not absolutely sure, how to use the 2nd VE Table?
Now i think, the first VE Table is for PIN 32 and 33, and VE 2 is only for PIN 34 and 35.
is this right?
And Is this always like this? For example, when i have only VE 1 activated, is PIN 34 and 35 dead?
And how do i have to tune the tables? I`m running a 4 cyl Turbo engine, and want PIN 32 and 33 for low load use with the stock injectors, and PIN 34 and 35 for a 2nd bank of injectors (so i have 4 + 4= 8 all together) for high load use.
So i will tune VE table 1 like stock, and VE2 will looke loke this (for examble):
0 0 120 180 280
0 0 100 140 250
0 0 0 0 0
0 0 0 0 0
And what do i have to select in the general folder? 4 or 8 injectors?

Thanks.
Then the next question. So i will use dual table, VE1 für low load and VE2 for high loads. But i will use 2 banks of the same injector types (bosh injectors with the same part number)
1.
So is it better, to use 2 tables which look absolutely the same, so that any bank will give 50% of the required fuel in any situation?
2.
Or is it better to create 1 VE Table (VE1) which lookes like stock, and only add the required fuel for more boost and rpm with VE2
3.
Or (this would be my favorite): Create 1 low load table which goes from 600 - 7500 RPM, but only from 0 - 150 kpa, and create VE2 for 600-7500 RPM, and this from 140 - 250 kpa ?
I think 1. is very easy to create, and both banks (injectors) will be used the same way, that the utilisation is the same.
But 3. is the clearest lay out, and it would be easier to tune, right? But i don't know if u have to choose the same "Frames" (like max map and rpm) fpr both tables.
And the last question:
How much injectors do i have to choose in teh GENERAL Folder? 4 or 8?
And if i choose option 1 and create 1 Fuel table with MT (or Mtweak). Will i have to scale it with 0,5, or does MT already know this, by enter 8 injectors?

Probably 2. will work best.
When using eight identical injectors and using two identical tables with four injectors for each table, you are effectively running a single table setup!
Using eight injectors you will have to reduce the injection durations, which will give the same effect as using larger injectors. Once you get very close to the opening time of the injectors, the system gets kind of instable as the amount of fuel injected in this short time cannot be controlled very accurately, as the injector is only half open.
It might work, but the effect is similar as with four larger injectors.
2. Should work.
3. Cannot work as you have the same injectors running on bank 1 as on bank 2. As far as I understood you would like to use bank one for low load, than switch to bank 2 for higher loads effectively turning of bank 1. This does not make any sense, as long as you use identical injectors!

ok,
1. i admit, that 1. makes no sense, you are right
And about 3: Its a bit similar to 2, but the scaling of the MAP is different. I want to use the 1st bank, too, otherwise it wouldn't make any sense.
2 means, that both tables have the same scaling, and 3 only means, that i have VE1 for low MAP, and VE for high MAP. This has the advantage, that i have more fields to enter the values for higher loads.
But i don't know, if bank1 is deactivated, if the engine runs MAPs which are above the VE1 table. (For example teh engine runs 250kpa, and VE1 has only 150kpa entered).
If it's not active then, this makes no sense.
But if it's active, i would like to know how much fuel bank 1 injects:
is MS interpolating, so it rises the fuel amount with the MAP above the entered values, or will it stay at the VE1 entered value?

If the VE1 table goes up to 150 kPa and you enter with 250, it will NOT extrapolate, it will squirt the amount for 150 kPa out of bank 1. But , the rpm and map arrays for VE1 and VE2 are the same, so you have to put 250 kPa in both tables. If you don't want bank 1 to squirt above 150, then put 0 there.el-hardo wrote:ok,

Hi, to you all,
I have similar question so I'll not start a new post. I have 5600 cc V-shaped 8 cylinders turbocharged engine but I didn't have the appropriate injectors for it. I have 12 240 cc/min injectors so I'm gonna place 8 injecotrs in the ports and 4 in throttle body. So the question is: Can I set up the 8 port injectors to operate simultaneous with VE 1 table up to 100kpa MAP (low load while cruising) in bank 1 and the 4 throttle injectors to operate at high loads (above 100kPa MAP) with VE 2 table in bank 2? I have MS II v3.0 board. Thanks in advance for your help!
