  1. Hello, I still have the problem with my oil temp. sensor, that I don't get the signal into the ECU - see also topic above. In the orignial dash I have the signal and it looks like, that it shows the correct value. It's a standard NTC sensor - see also attachment. Do I have to connect it instead to an analog temp. input to an analog volt input like wiring a NTC temp sensor in a piggypack situation? Thanks vor your help! Andreas
  2. Hello Simon, Trigger2 (camshaft) signal is sorted & the engine is starting - thanks for the help!! I have now a question concerning the oil temp. sensor. The BMW E30 M3 has a original oil temp. sensor fitted and a gauge in the dash. The sensor has only one pin for the signal and sensor ground is via the engine. Can I also use this signal to have the oil temp. in the ECU? Can I split the signal or do I have to mount another oil temp. sensor for the ECU? Thanks & regards Andreas
  3. Hi Simon, thanks for your feedback. I'm working on the Trigger2 signal, that it looks proper. One question - would it be best to have the Trigger2 signal short before the gap of the crank shaft trigger and before TDC is reached of cylinder 1? In my case, the sensor for the crank shaft trigger is about 90° before the gap reaches TDC cylinder 1. What would be the best position for the trigger2 signal? Thanks & regards Andreas
  4. Hi Dave, I noticed something in the help file in the chapter "Trigger 2 Sync Positioning". There it is written, that with Mutli-tooth / Missing the trigger 2 edge shouldn't occure in the rigger 1 gap. I made a snap shot with the trigger scope - see attached file. Can it be, that there is a mistake, that I have to reposition the trigger1 or trigger2 sensor? I also found in the chapter "trigger offset", that If the gap passes the sensor before TDC1 in normal engine rotation direction then the offset number will be negative. In my case I get the missing tooth of my 36-2 trigger wheel about 90° before the engine reaches TDC. If I crank the engine I catch the TDC marking at 90° but if I read whats written in the help file, I shoul catch it at an offset of -90°. If I look from the front onto the trigger wheel, the engine rotates clock wise (so anti clock wise when looked in driving direction). Thats also not clear to me. Thanks & regards Andreas
  5. Hi Dave, 1st I wish you all the best, that you are fully well soon. Thanks for your help with the map. As I'm at the moment in Le Mans and will be back earliest in 8 days, I will then have a closer look and try the map. One thing, the engine is a naturally aspirated one, not turbo charged - this is why I map it with the TPS. Will keep you updated on the progress. Thanks & regards Andreas
  6. Hi Dave, you had a chance until know to have a look at the pcl file? Thanks & regards Andreas
  7. Hi Dave, find attached to this post the pclr file. Thanks for your help. Thanks & regards Andreas 150511_SD_V4.pclr
  8. Hello, I'm at the moment struggling to get my BMW E30 M3 S14 engine to start with an i88. I did a complete rebuild of the car and the engine - now everything is finished and we wanted to fire up the engine, but it's not starting correctly. If we try to start it, it's backfiring trough the throttle bodies, sometimes into the exhaust or even in the compression phase. When we crank the engine and check with the timing light the TDC everything seems to be correct. The sensor on the crank shaft trigger is located about 90° before TDC and with the strob light we catch the TDC mark at around +90°. The ECU shows while cranking about 250 rpm - which seems for me correct and doesn't show any trigger error. When we try to start the engine, at one stage it backfires and then we get an trigger error - the rpm's go somewhere. We tried already several ignition angles, fuel injection timings, checked if the timing is not 360° offset, etc… It seems like the ignition timing is way off, but if we check the values it looks correct! Injector test done - ok Ignition test done - ok Oscilloscope check of trigger 1 & 2 - looks ok Ignition cables checked & changed - no change Wiring pin layout checked - couldn't find anything wrong Sensor & power ground checked - couldn't find anything wrong Details to the engine: BMW S14 engine 2,3 L naturally aspirated Crank trigger wheel 36-2 reluctor/inductive type sensor Cam trigger BMW E34 M5 reluctor/inductive type sensor LS1 single ignition coil Injectors Bosch 0 280 150 804 Mapped by TPS Has somebody experienced similar issues? Somebody a good idea what could be the problem or what to test? Thanks & regards Andreas
  9. Hi, thanks for your help! I will have a look and will see if this solves my problem! Will come back when its working. Thanks & regards Andreas
  10. I only have the Vi-PEC ECU in the car. Regards Andreas
  11. Hello, I am just on the way to finish the engine loom for my BMW E30 M3 S14 engine. I want to run the original dash for the engine speed with the Signal from the i88 - the signal for the ECU Comes from a 36-1 crank trigger wheel. Has anybody experience how to wire/connect the original dash with a Vi-PEC ECU? Thanks for your help! Andreas
