Visit Preferences to set your user name Summary of change: My name is Paal, working and playing with toy cars in Bergen, Norway. Time to update progress in 2009 -- 2010.... ---- '''The goal''' Apply a GenBoard/VerThree (V3.3) to my Polizei-golf's new engine. '''The car:''' http://jeje.je/creative/polizei/polizei.jpg '''The car, today:''' http://i47.tinypic.com/15gp7rd.jpg '''The engine:''' *16v KR engine with S2 pistons *S2 intake manifold with S2 TB throttlebody [http://www.s2central.net/images/3B_ECU_Schematic.jpg TPS schematic] - pinout: pin 3 = signal, pin 2 = signal gnd, pin 1 = +5v *OEM 60-2 trigger wheel, HALL sensor - pinout: pin 3 = signal gnd, pin 2 = signal, pin 1 = +5v *K24 turbo *440cc (high impedance) injectors and 3,5 bar FPR *034EFI idle stepper motor [http://www.034motorsport.com/product_info.php?products_id=161 link] (Currently unused, using idle screw on TB) *034EFI wasted spark coil [http://www.034motorsport.com/product_info.php?products_id=40 link] *034EFI IAT sensor [http://www.034motorsport.com/product_info.php?products_id=117 link] *OEM "blue" water temp sensor *Chinese fuel pump mounted inside tank. Waiting eagerly to see how long it lives. ---- '''VAG 60-2 (BOSCH) Hall trigger:''' ''Mounting instructions - udpated'' Note the following important differences if you are planning to use this kind of trigger assembly: [http://i47.tinypic.com/iput6r.jpg Difference between original oil seal assembly and new trigger assembly] - *New* Trigger assembly has o-ring seal - do *not* use the paper gasket. Use your favorite gasket sealant on the outer side of the o-ring. - Hall-trigger bolt and wire will need to be grinded down ~1,5-2 mm to get clearance from the block. Ensure the trigger assembly plastic casing will be flush with the block, and that the bolt + rubber grommet for the hall trigger is sufficiently grinded down. ''Mounting instructions'' After a miserable user-error during mounting, I had to remove the transmission + clutch assembly to re-align the trigger wheel. This happened at 2500 rpm, no load, and stopped the engine with a nice pop out the exhaust. ''Cause'' When I initially mounted it the ring got pressed too far onto the crank, and the result was rubbing against the oil seal --> trigger wheel skipped ~45 degrees. In addition I did a really poor job at modifying the steel cover to accomodate the trigger itself. ''Solution'' - Attach the oil seal / trigger assembly - Carefully push the trigger wheel onto the crank - Fit the flywheel onto the crank, and tighthen carefully. This will push the trigger wheel far enough onto the crank, and this ensures it wont rub against the oil seal. - Ensure there is no contact between steel cover and trigger wheel, and that the hall trigger itself has enough room. - Note additional mounting instructions above The orange plastic clip is nice to use for alignment, since it will give you a somewhat predictable "TDC after the trigger" in VEMS (it aligns the wheel at 85 degrees BTDC). If you need to remove the triggerwheel, use the screws holding the oil seal to the block, and screw them gently into the brass threads. This will push the ring out. -- [http://i43.tinypic.com/nwmott.jpg Trigger wheel fitted to my crank, illustration overlayed showing 85 degrees between missing tooth and sensor] German thread: http://www.golf1.info/forum/thread.php?threadid=14109&page=2#post151865 and [http://jeje.je/creative/polizei/vems/elsawin-polo-axu-hallsensor.jpg ELSAWIN screenshot here stating it is a Hall sensor, (ro/gn) goes to G40 pin#1 (which we know is Hall), and EGR-potentiometer pin#2 (reference voltage) (TeroK)]) - 85° BTDC with cyl1 at TDC [http://i43.tinypic.com/2rf8zyc.jpg reference] - OEM parts numbers: * sealing flange with 60-2 trigger wheel and plastic clip to align wheel with housing: 030103171L (~65 EUR) * Hall sensor with ~15 cm wire: 030906433Q (~40 EUR) * Steel backing plate: 030103647E (~20 EUR) - [http://forums.vwvortex.com/zerothread?id=3516017&postid=45479900#45479900 some modifications needed] -- also possible to use OEM PG (g60) plate, with minor cutting. * [http://photos.fotki.lv/photos/4/W0001903/000190213/000019021289_%23_3_%23_GintsK.jpg image of connector + crimped wires] - part numbers: ** connector: 1J0973723 ** 3x crimped wires: 000979133A ** 3x rubber seals: 357972741A '''trigger settings example from emil (2007):''' * Falling, Multitooth * with trigger tooth 3 * TDC After the trigger = 62 degrees ** is this measured or speculation ? verified via strobing ? ** it's easy to get into the ballpark (+-6 crankdeg) with InputTrigger/TriggerLog, but it's really a good idea to verify via strobing anyway ** After strobing my engine I ended up at 64,5 degrees "TDC after the trigger".

Ordered via Jörgen. ''16.08.09'' MAP, TPS is calibrated. IAT + CLT needs calibrating, and Im getting ready to try out some configs to see if it starts. Using the V3harness on the engine I had to reverse the injector order since the main harness is on the transmission side of the engine. E.g cyl 1 is labeled inj D, cyl 4 is inj A. ''18.08.09'' IAT+CLT is now calibrated using above hex files. Waiting for last check of MSQ file before attempting strobing to verify trigger settings. ''25.10.09'' Car is running pig rich, currently running boost control directly on wastegate (max 0,4 bar). ''25.04.10'' Car has been driven regulary for a week, still not properly tuned. Runs very well, even with no boost restriction. I had problems with the car dying at random intervals - this was traced back to either fuel pump relay or signal wire to the relay. After putting in new wires and a different relay the problem has gone away. ''24.05.10'' Interesting oil leaks from the crank/transmission housing. Reason: trigger assembly not mounted correctly/not modified correctly. Starting to enjoy taking the transmission in and out.
