Audi 90 Typ85 Quattro Jemo Motorsport (http://www.jemo-motorsport.de/)
Engine:
- AAN 5Zyl 20V turbo
- 2226ccm
- stock head
- JEMO H-profile rods
- JEMO Wössner pistons
- JEMO intakemanifold
- JEMO T4 exhaustmanifold
- 60mm Tial Wastegate
- Holset Pro52
- 114mm Downpipe / 88.9mm Exhaust
7A Cams reclocked
- no 7A flywheel (for 7A flywheel and auditrigger => cam-HALL inverter would be needed, but not interesting for HALL-HALL)
- 1xBosch 044 to catchtank
- 1x Aeromotive A1000 from catch to rail
- ID2200 high-Z Injectors
ECU:
VEMS 3.8 Board
HALL/HALL
FW 1.2.31
1xEGT
High Z-only 30V Flyback
Ignition Driver 6+2 (I recommend 2+6 for COP VAG)
2xKnock input
400kpa simplenipple MAPconection
PTrigger Hall
SecTrigger Hall
LSU 4.9
Wiring/Sensors:
Crank 60-2 HALL from VW Polo
Camsensor original S2 (1 window HALL)
- Tachometer EC36/4 P259 CH0 Low Current output(0.3A)Grounding
- with 1k (internal) pullup to 12V
- FuelPump EC36/15 P259 CH5 Low Current output(0.3A)Grounding
- prefer a free stepper output (or injector or IGBT output), more rugged
- CEL (warning light) ... a p259 output perfect for this
- shiftlight ? a p259 output perfect
Ignition (firing order 1,2,4,5,3):
VAG COP TFSI Coils @1.97ms dwell
Zyl 1 Stepper output A EC18/4
Zyl 2 Stepper output C EC18/5
Zyl 4 Ignition Output 4 (logic level) EC36/11
Zyl 5 Ignition Output 5 (logic level) EC36/12
Zyl 3 Stepper output B EC18/10
- stepper D is traditionally used for ign on 20VT engines, but as long as configured accordingly, it matters little of course
Injector:
ID2200 HighImp
Inj 1 InjGroup0 EC36/18
Inj 2 InjGroup4 EC36/9
Inj 4 InjGroup3 EC36/8
Inj 5 InjGroup2 EC36/19
Inj 3 InjGroup1 EC36/20
NO IACV
BoostValve will be connected in future
- would be useful; possible 2 valves; one on bottom side and one on top side of wastegate actuator
- Connected MAC boostvalve to EC36/7 InjChannel7 - wg buttom permanent pressure, top triggert pressure via mac - sadly the a1000 fuelpump dont allow more boost than 2.2bar, we'll install 3x044 instead.
First tests with Wastegatespring pressure 1.7Bar@5000rpm shows 100-200kmh in 6.0 sek messured with P-Box.
Power estimated 900hp+ with 3bar+ boost.

Now 3x 044 Fuelpump for good e90 delivery.
Changed to CATCAMS Camshaft's, went back to Audiwastegate, remap with 2,5bar boost. Measured 898PS/ 950NM

On higher boost intaktemanifold begins went out of the silicone hoses. With other intake we will try to go to 3,0bar(400kpa)
