im running .63 on hotside with OEM AAN exhaust manifold, is it too small?
I would use .82 hotside with gt35, but this isn't your problem.
OEM AAN ex manifold is good up to stock turbo, anything over it is pure power killer. Actually AAN ex manifold is so crap that even with stock turbo i would recommend rs2 ex manifold. With gt35 power levels you need wagner or similar ex manifold. I would go for the tubular.
Look at the efiexpress documents for all of your questions. These are fairly basic and the answers are there. In summury the VE number is a number that vems uses to internally calculate fuel, so its not ms of injection. The req-fuel comes off an equation from your injector size.
Hi, im new in Vems. What is the values you put in the VE table? Is it persent of something or is it ms (millisecond) or something else?
Se you guys have way different Req Fuel numbers, are you using the formula or what?
Thanx
You can use auto tune for first and see how is changing.All ve table is custom for every car.It's depends from you injectors,turbo,how good flow your engine head,from everything.
VE in an ideal world stands for volumetric efficiency.
This basically says how well your engine flows.
It does not depend on injectors at all, it is a model which tells the ECU how much cylinder filling there will be at a certain MAP and RPM.
On a mass-flow based system, cylinder filling = mass air / rpm.
On a speed density system, cylinder filling = (MAP * VE)/ IAT.
If you need to alter VE on a speed density system when you change injectors it means that either you did not manage to correctly linearize the injectors (dead time, slope characteristics) or your ECU does not provide the possibility to do it.
And that way your injector characteristics get coded into the "filling" map (or VE).
It is similar on a mass-flow system. If you need to change anything besides the injector calibration (dead time, slope, size) on a mass-flow system, such as the main fuel map, you are also not calibrating the injectors correctly.
hello everybody. This is my first post here on this forum. i am new, never worked with a standalone ecu before. I have an mc engine with 630cc siemens deka and garrett gt30, 60-2 wheel in the flywheel seal with hall sender and sec trigger is the distributor with one window(ive cuted down the oder four). Im just looking to get it started to check for leaks before i go to a pro tuner. I run vag COP. I repeat im new to this, any help will be highly apreciated. i've atached a cofig file an a trigger log file. I just want to get it started. thanks a lot
