| Yugo C20LET |
My first page here will be actually my last project. It's a small car made in Serbia with well known c20let engine from Opel Calibra turbo. Goal was to make a car run as it should with Vems in less than ten days (tenth day was drag race in Osijek, CRO). All wirings were made according to Phat Bob guide, like all others car I installed Vems before, luckily without any problems. Harness was made of 0.75mm2 automotive grade wire, with exception of ground wire 6mm2.
MAP and MAT sensor used for this install was Bosch 0 281 002 401, same from webshop, with difference in range of it. In webshop you can find it's 300kPa sensor, while actually its 330kPa sensor.
- Primary Trigger
- standard VR sensor
- stock 60-2 trigger wheel
- 19 teeth before TDC
Secondary trigger was taken from Astra F GSI which uses DIS module.
Ignition subsystem was wasted spark DIS module droven with two IGBTs.
Injection was fully sequential, made also according to PhatBob guide, with Siemens DEKA 630cc injectors used, and with 30v flyback diode installed.
Firmware used in this case was 1.0.78 because of possibility of using ignition retarding when using NOS, with only input configured.
Two more inputs were used for launch control and flat shift (aka shift cut), configured to cut only spark while shifting gear, with 250mS used as longest period of cutting. Be careful when playing with launch control, you could destroy your exhaust system, dramatically shorten turbos life and make very high EGT

- Successfully installed Vems, needs to be tuned
- Triggering
Used OEM 60-2 crankwheel and sec trigger, but couldn't use it on falling edge, so used rising for HAL sensor on cam. 13th tooth is TDC on 1st cylinder.
- Ignition subsystem
OEM coilpack used, with removed amplifier.
- Fueling
440cc/min Bosch "Greentop" injectors used, with 30V flyback, fully sequential setup.
- Engine sensors
- OEM CLT
- MAP&MAT Bosch 0 281 002 401
- WBO2
- EGT
- OEM HAL and VR

- Successfully done. Engine was fully rebuilt by RNN team with upgraded pistons, conrods, cams, gt2871r, full headwork and a lot more funny parts. :)
- Wiring
Wiring for VEMS is temporary made of OEM engine management installation (will make new once).
- Making of new wiring harness in progress. It's a bit harder job than I had it in my mind. FIAT wanted to put a bit more wire than Coupe needed, so now I'm trying to make some sense of those spaghetti :) Some strange misfire begun in last few days, first about 250 kPa, than 240, another day 230, 220, 200...
- New harness is finished today. Misfire was probably caused by broken COPs. I changed them with VAG active COPs
- Ignition subsystem
Fully sequential COP, OEM COPs used
- Now VAG active COPs used. Removed IGBTs, no need for them any more.
- Even with "old type" of VAG COPs i had very weak spark, so I needed to lower resistance between VEMS and COPs. Now it's very strong spark, and no problems in boost anymore.

- TODO these days, just ordered parts for it.
- This car came to my workshop with VEMS already installed by someone else. Bad flyback, poor wirings and not so good configuration and mapping resulted in major engine damage. Engine is mechanically fixed, and it's time to fix VEMS...
Can you tell serialnr of this VEMS ? So we can get some idea of its history. Btw, nice progress. Mention your URL for any WebShop order / discount negotiation.
Yes, I'm holding it right now in my hands. It's 2322. v3#2322 was sold as a board (so home-assembled).
- Started making new harness. Resoldered VEMS completely, reconfigured hardware to match engine hardware, put it in a new box and started spaghetti job. I also installed 30V flyback diode inside.

- no secondary trigger at the moment, need to make something. I'll probably try to make it with hal sensor from webshop
- Fueling
- Need to make sec trigger for sequential injection

- successfully done, with a looooot of problems, need some time to write...
- We work with these engines mostly, so I am interested in your experiences, problems, sollutions. - MembersPage/ZoltanAlmasi

- unfinished, will finish/write about it after painting :)
| Fiat Punto 1.4GT gt2871r |
- successfully done, after that upgraded turbo and injectors, will write later...

- To do. Collecting parts for it. Slide throttle bodies, 340 deg/10,5mm cams, lightened, polished and balanced crankshaft, very light pistons, and a lot of funny parts :)
