VEMS v3.3 with AudiTrigger - how to run Audi V8 ABZ on this?

Hi.
6 months ago I bought VEMS V3.3 with:
primary trigger: VR
secondary trigger: AudiTrigger
He worked with 20V turbo engine. The engine broke down, and I bought the another Audi engine, V8 ABZ. I don't want to modify anything in VEMS board.
What is the simplest way to run this engine on VEMS with my trigger setup?

GintsK

Same three sensors?
I have same case, but problem - my customer is 250km away from me. Auditrigger seems working on benchtest. But in real life engine now runs without hall sender...
I use auditrigger divided by 2.
136 teeth on flywheel.

So, when only crank sensor are in use, engine work with wasted spark?

Your crank signal must have a reference in the form of a either one or two missing teeth.
This will allow wasted spark and semi sequential injection.

In this case it is coil type with reference pin on crank.
Yes it run in wasted spark mode. I hope we will be able to run fully sequential. Car is not tuned jet.

I wire coils as wrote [email protected]:
QuoteAssuming that the coils are wired like this:
Coil 1 to EC36-pin35
Coil 2 to EC36-pin33
Coil 3 to EC36-pin34
Coil 4 to EC36-pin36
Coil 5 to EC36-pin11
Coil 6 to EC36-pin12
Coil 7 to EC36-pin24
Coil 8 to EC36-pin10

With a firing order of: 1-5-4-8-6-3-7-2 give a firing order of:
0 - EC36-pin33
1 - EC36-pin24
2 - EC36-pin34
3 - EC36-pin12
4 - EC36-pin10
5 - EC36-pin36
6 - EC36-pin11
7 - EC36-pin35
and, I think at start I'll use only the crank trigger and wasted spark mode. What should I configure in VemsMT? When I run AAN engine on VEMS (2,2T 20V) I have broken hall sensor and similar config (but with 5 coils) and engine work correctly.

And another questions:
I want to charge my V8, so I need some free FET's to control boost controler valve (and other stuff, like idle air control valve)
1. Injector resistance is 16,8ohm. I wire it in pairs. Should I wire any resistor in sequence?
2. I wire injectors like this:
Injector 1 and 4 to Injector1 ch.1 (EC36-7)
Injector 2 and 3 to Injector4 ch.8 (EC36-20)
Injector 5 and 8 to Injector2 ch.2 (EC36-19)
Injector 6 and 7 to Injector3 ch.4 (EC36-8)
Is this correct connections?
How configure VEMS to run that configuration of injectors?
